This is a video on how to repair the BP94-02084A Digital board for green lines. It covers the replacement of 2 RAM ic's. An easy way to check if this is your problem is to look at the difference between SD and HD signal sources. HD requires much less RAM to up convert than SD does, thus if HD looks much better than SD (see intro of video) then there is a good chance that this is your problem. I have repaired multiple boards with no call backs!

I have never in my life seen a guy like you, who can solder in a chip, with such ease, you sir should have been a brain surgeon, you must have had years of practice to get that good. you make everything look to easy.

[@stroise256]

awesome soldering job. You made that look so easy. I dont know how the solder didnt go over to the other contacts while soldering to cause a short. Very nice video for people with the same issue

[@norcal715]

I have changed this part in your model 2 or 3 times under warranty, it is quite involved but a fair repair shop should not charge more than 150 in labor. However if you are going to just toss it out, you should at least try to remove and re install your old board just to see if you can do it. If you succeed then order the used one and save some money!

[@whiskeyify]

I've watched some videos here but have never seen it done this way, but it makes sense to me. If you apply the solder to the pins you might get too much and make a solder bridge. This seems like the best way to do it.

[@norcal715]

Enter the factory mode, with the tv off on the samsung remote press in this order: mute, 1, 8, 2, power. go to option and then to WD Count. Thats the Watch Dog counter and counts digital board errors. you can reset it by selecting user reset, then let the set do its thing for a few days then go and check the count again. If it has incremented then the problem is on the digital board, possibly ram ic replacement would repair it. Thank You

[@norcal715]

No it is a bit more involved that just unplug and plug back in. It requires alignment after re installation. As far as the worth, it's up to each person, there may be someone that thinks its worth 1000 working perfectly and the next guy that would not give you 25 working for it. As far as an independent shop installing a used part, we do it with the understanding that its paid up front, and if it doesn't work oh well, and no warranty. Hope this helps. Remember their time is their money. Thanks

[@norcal715]

if you are seeing green in the dark areas then adjust the color wheel index. Most likely that will solve it. The color wheel rotor and sensor may be in need of a cleaning. Try that and let me know. Thanks

[@norcal715]

The flux causes the solder to become much wetter and stick to the leads, Flux also causes a wicking effect. Trust me it is much easier to solder when there is not a camera 3 inches from the work!

[@TheCharlemange]

How did you determine which ram chips were the problem? Did you guess? You left that part out.

[@priestblood]

I guess the service manual to find memory allocation address ,or a good old scope to check address lines and fine the faulty chips ,but if your unsure replace all memory still be cheaper than a new tv

[@norcal715]

Sounds like a bad DDP IC, bring up internal test patterns, with Samsung remote and set off press in this order: mute, 1, 8, 2. Then go to DDP1011 press right arrow to enter, go to test patterns and scroll through them and see if you still have lines. If you do then the DMD board is suspect, specifically the DDP IC on the DMD board.

[@norcal715]

you can get both parts from samsungparts . com. just make sure to double check the exact number off of your old digital board on the little white tag next to the 2 antenna connectors.

[@norcal715]

Yes do the HD/SD test. GPU affects both HD and SD signals equally. Ram affects SD more than HD.

[@everythingsupersaiyan5789]

Hello there norcal, I have skinny straight perfectly spaced vertical black lines on my Samsung DLP Model Code: HLR4667WAX/XAA They are in exact number sets. I think like they are in sets of 8. They go all the way from top to bottom of the screen. Starting from one side of the TV there is a set of black lines, then a space, then another set, then another space, etc. Taking in consideration of my description I will try to type it using the letter Capital I's to show you how systematic they are.

[@norcal715]

does it make a buzzing/humming sound? if not it could be either the color wheel sensor of the DMD board. Sounds like the color wheel is running over speed and that causes a whining sound.

[@2LAZY-2EDIT]

So tried cleaned color wheel, black sensor on wheel and on PCB board below wheel, cleaned up dust around to be sure, but still there it's def there when HDMI cord, VGA and component, but with cable seems a bit better

[@norcal715]

Just one question, Was your friends digital board the exact part number? because the analog boards are matched to the digital boards. and if you try and use a 1659 in place of a 2084 then no sound is the result. as far a a 4 pin cable, the speakers plug in somewhere in middle of the board and not in the back as all the other cables.

[@norcal715]

So I watched your video and if you access the service menu (with power off press in this order: MUTE, 1, 8, 2, POWER) go to DDP 1010, go to test patterns and see if the test patterns have the lines. If they do then the DMD board is the fault, if no lines then the digital board is the fualt

[@norcal715]

No, sorry I order them as needed. But last time they were on Nationwide back order I got them in about a week.

[@lostsledder]

Must have been the same - it worked. There was a 4 pin header that I messed during reassembly. The picture doesn't seem quite as good as it was. Would it be possible to send my old one to you for repair? Thanks for your help.

[@norcal715]

I have done too many of these for it to be a BGA problem, The DNIE ic processes SD and HD the same and the problem is much less or not there at all when less scan conversion is done, remember it requires way more memory to up convert 480i or p to 720p needed by the DDP ic, however it requires very little conversion to convert 1080i to 720p. I have however seen some problems caused by BGA problems but with this propblem and multiple repairs for the last 5+ years I just dont think it's it. Thanks

[@Tazer98LV]

Excellent video. This is the closest example of the failure of my HL-T6756W. Began getting dim on last day the screen froze at a commercial image. Thought it was the cable company. Picture went black. I replaced the lamp. Turned on but nothing. Lamp was bright. Couldn't get to settings via remote. Went to panel brought settins up and they displayed fine. Now a green-like display appears. Sound but no picture. Could this be the same problems as in the video.

[@2LAZY-2EDIT]

thank you \great video had this issue for years now bought tv in 2005-2006, ill tryn repair soon

[@serg71ut]

Excellent video. thank you. I have a problem on the same unit. Unit has a whining sound when initiated. I believe its color wheel related. It whines unit does not turn or lights flash in the front on power button. Can you tell me what you think it might be?

[@everythingsupersaiyan5789]

Please help. I can replace the part my self. Diagnosis on the other hand is very hard. I used to work with a solder iron and replace chips, caps etc. I just need to know what part it is. Then i can find one online somewhere. I have tried researching and if I had to choose I would say its a dmd board from what other people have said. I just want a expert opinion. You look like you know what your doing and that your good at it too. I dont have sound on my PC so I couldnt hear.

[@myopinion140]

Hi, good job. how did you know that these were the two chips causing the problem and not the other two, is there a way to test them with a digital meter before removing them. thank you

[@esj4373]

have in mind to go with the pana TC-L55ET5 OR THE LG55LM6700 leaning towards the panny,will see both tomm in store to see the picture quality,sharp is another possible brand,thanks for the info

[@annewahl4422]

One of the little "hooks" came off with the old chip. NOW WHAT? Do I have to replace the whole chassis?

[@2LAZY-2EDIT]

So tried service menu no luck I have it set to 30, any thing above or lower looks worse, I can always make a video if it helps, but maybe ill try your fix and see if it works

[@tye3333]

i have found if you get a full green screen on the samsung SP61L3HX it is NOT these RAM chips (4 in total), hope this might save someones time.

[@foreverjjun]

Hi, I am seeing many videos about this problem and solution. I see many videos claming it is GPU problem and fixing it by reballing the GPU. And I see you fixing it by replacing the Ram. Do you know how to find out what is problem between RAM and GPU? Is it by checking HD and SD channel as you mentioned?

[@motorhead45102]

I don't know what my problem is but I have a 39" insignia LED LCD tv and it has this similar problem, no where near as bad by far, but I have been noticing, mainly when there's video movement any area's of the video that is black is where I notice the random green shades/lines. I did mess with the tv settings and one feature I turned off helped a lot but very faintly see it still in certain spots but that feature was insignia motion 120hz. I turned that off and its an improvement, but its always had that turned on a never has shown up this green video before. but if you could maybe give some idea what I may have going on let me know

[@justineubank9547]

NorCal, I dropped my tv off at a local shop. They are telling me that they can only replace the complete digital board. I was interested in sending out my digital board to you to replace the ram chips. Are you available? What is the best way to contact you????? Thanks

[@2LAZY-2EDIT]

Got question before I start working on tv, my issue is on scene where it's supposed to black or just dark, it has a green shadow to it, say like black hair, beards even come up green-ish

[@williambroadhurst5780]

How did you know which ram ic chips were bad? I have a friend with a similar problem on his samsung DLP tv. What do you think of just replacing the entire digital board?

[@Incoming21215]

Very nice video once again .......

[@snapon80]

Great video! one thing....how did you determine that those two chips were faulty, do they have a give away like burn marks i know capacitors bubble? i have this exact problem and would like to learn how to determine its that part. thank you!!

[@KillerZero259]

norcal715, i love your videos! very educational and informative!!!

[@MANMAD1]

Nice video . I have same problem with my hlr 5067. Sent digital board to a repair shop in MI. jd electronics.They said they were having good results with reflowing main chip . I got my board back and have the same problem . Maybe I can send the board to you . Thank you .

[@CHIBA280CRV]

Can that be the same problem I am having with my Runco projector? The green picture I have ? It is DLP VX1000 c.? Thanks.

[@2LAZY-2EDIT]

Actually never went into service menu ever, I gotta look into finding manual then give it a try

[@joshbarton]

I have a Samsung HLR4667WAX/XAA. Here is the issue: When the tv is fully assembled the lamp light in front flashes for about a minute or two sounds like everything is powering up then it shuts itself off and Standby/Temp light flashes. After looking into it with covers off and door switch unplugged tv will run for at least 5 minutes before shutting off. Lamp is on color wheel is spinning. I have no picture, no sound, menu does not display. Im thinking digital board replacement?

[@SuperRnine]

How did you know which ones are faulty ?

[@mem-vz6on]

I don't think it's the exact problem cause I'm on HD channels only. almost all are 720 & 1080. Although when I first noticed a year ago it only did it changing channels and I recall it was worse when going from 1080 & 720 to a program broadcasting a 480p signal

[@esj4373]

got a samsung hlp 5085 with thin black vertical lines,there is 10 groups with a 3 inch space between,each group has 8 lines,any ideas what this may be ?

[@esj4373]

what is the unit worth in the current state,besides this issue the unit is in mint condition,unless the board is like changing a video card in my computer i probably would not get involved,if i purchased a used board would a repair center install it ?

[@norcal715]

did you try the index delay adjustment in the service menu?

[@esj4373]

so if i had a service center repair this what range would this be for labor,possible i would do if there was a video to follow but this looks involved,where does one buy a used one besides ebay,thanks for your replies

[@michaelpleasant8870]

I am interested in getting my digital board repair. Can you repair mine? If so, what's the best way to contacy you?

[@SpectrumOnlineDeals]

I have seen a video about re floing the dnle ic for the same green picture is that correct? or what do you thing about that. I just got one that keeps turning on and off and on and off etc. I disconected key pad and remote sensor but it does not make any difference.its not shut down issue but keeps turning on and off you can hear the melody every time it goes on and off.

[@esj4373]

whats the general price range to repair this

[@norcal715]

Part number BP96-00696A from samsungparts . com $529.00. you may be able to find a used one for less elsewhere.

[@marielaalvarado8389]

Can you tell me where to buy the ic's? I looked online but havent found anything. thanks

[@marielaalvarado8389]

it says nationwide backorder. Do you have any in stock to sell? thanks again!

[@Jeters123]

I have this same tv..it will power on then go to green lines then the screen will go black..sometimes the tv will work fine for a few min. then the screen will go black and none of the buttons on the tv work. the only way to turn it off is to unplug the tv from the wall.. any help would be great thanks!

[@everythingsupersaiyan5789]

The spaces are bigger between sets though.

[@norcal715]

If it is a LCD tv, it sounds like a LCD Panel problem, that is if the lines are like 1MM wide. Most likely a drive pack failure that is bonded to the glass and no way to repair short of replacing the entire LCD panel. Sorry

[@slsnack]

After my husband replaced the chips, now he can not get a picture. The lamp comes on but there is no picture. What now?

[@norcal715]

The main brand I recommend is Panasonic. I see only a fraction compared to other brands. I cant recommend LG anymore since they started outsourcing from China and the same company that makes the throwaway Vizio uh-ohs, Amtran. Sony and Samsung so-so reliability.

[@Jeters123]

am i able to buy and new digital board? if not where can i buy new ram ic?

[@esj4373]

so what i`m getting online with the brand new part and professional install this looking like a 800-900 price which seems insane and probably better off buying a new quality led unit for 1200 - if i go with a self install used board is this more or less like installing a video card in my computer or more involved,i`m unemployed now so money is a problem,you have or know anyone in the new york area who has knowledge on these samsung 5085 units

[@esj4373]

prob going to get a new led unit,looking at the LG 55 LM6700 - would you consider this manufacture relialibty on par with samsung,pana,sharp or is it just the luck of the draw lol ! hopefully i get 10 years out of a led as there seems less to go wrong then a 7 year old dlp,maybe you feel or know otherwise !

[@norcal715]

sorry, i forgot a key command. with set off: mute, 1, 8, 2, power. try that

[@GOLOBILLY]

Hello I would like that you were more videos of lcd and plasma here in mexico we are in diapers with att failures: William

[@rodolfogarcia9461]

how can i get those chips, i have the same problem?

[@Jeters123]

Wow way to much money for the parts! But thanks for the help

[@siggustafsson6334]

How do I determine what ram chips are bad?

[@007cttina]

do you fix these boards if i was to ship it to you. i have been trying to get this tv fixed for some time now. i have bought 4 different used boards from tv replacement part shops but they didn't work either. it would be greatly appriciated if you did. :)

[@stevegajadhar896]

hello i.m from trinidad tobago ,, does watch your videos , must say very good , tell me do u supply parts also? cause i.m always looking for parts for flat screen tv ,, if u do maybee we can do some business,,

[@esj4373]

can`t seem to bring up test patterns

[@akabobbybox1]

Wanted to know if you had any idea for what could be my problem. I have a 72" Samsung dlp tv (HL72a650c1f) that I bought in 2009. Had the on/off problem, so I replaced the lamp first. That did not solve the problem, so I ended up hiring 2 technicians to some what fix my problem. First guy stated it was the digital board (not so), 2nd guy fixed the on/off issue by replacing the power supply and ballast. However, now the picture does not have the color red in it. Fired them and I have been researching all dlp issues on the net (nothing like my issue yet to be found). Found some one selling the same tv with the on/off issue, so I purchased it for parts. Swapped out the entire light engine but removed his ballast for mine and presto, it worked. But now after a few months my new problem is its turning on and off again but this time I can hear audio and after a few attempts the screen comes on but within seconds the color fluctuates and on and off cycle continues. Any idea how to fix both issues? My old tv with no red in picture and my new tv color changes rapidly and then no picture to just audio and back to the on and off cycle...

[@norcal715]

check the cap on the ballast as well as the 2 big filter caps on the power supply board and see if any of them are bulges. that will cause the on off problem as well as color fluctuations. as far as red color sounds like digital board setup problem, or color wheel problem

[@akabobbybox1]

Ok, thanks for replying. Wish I knew you personally because the idiots out here don't have a clue or a tenth of your knowledge and I've already fixed other problems by watching your videos. Again, thanks a bunch!

[@AnonyMous-pc6vo]

Hey I have an HLR4667wax/xaa, screen flickers on s video and coax but is perfect on component. I think it's the digital board. Where can I find those Samsung RAM chips? I have been having trouble finding them. Thanks

[@norcal715]

Sorry, it have to be brought to me, as I have been burned in the past with mail order and credit cards. Hope you understand.

[@lostsledder]

I had a friend with the same tv as mine with a different problem - his tv would turn off after a period of time (samsung dlp tvs model hlr5067) when I swaped the boards out it fixed my green line issue, but now I have no sound. I know there is one 4 pin connector with a filter on it that is not plugged in, but I don't remember unplugging it and I don't see anyplace to plug it into. Can anyone help me out?

[@norcal715]

it is one per package

[@esj4373]

do you have a email i can send you a couple of pictures on the line issue,maybe get your opinion,the picture plays with the lines for about 10 minutes and then screen goes dark,you did say it may be the dmd board in your passed email but figure i show you the pictures.

[@everythingsupersaiyan5789]

Please help I need your expert opinion.

Please checkout my upload and see if u think this is my problem. Mine is not staying that way but will start with a horrible noise and froze picture the look very similar to this and go blank. Can't get it back until change channel. Did it when I got TV second hand but only noticed a few times after changing a channel. Now it does just watching it and as much as 10-15 times a day.
