What a great crash course in TV repair. Thank you for adding a leaf to the tree of knowledge.

[@mikestearman2913]

Thanks for the clearly presented lesson. Module replacement is usually the best way to go, because most folks aren't adept at desoldering/resoldering components.

hey boss, what's the name of the small metal part within the TV - where you screw the screw to mount the TV.... two of mine broke within the TV... maybe can get replacement... thanks

Hello Mr. Jimmy, My name is Velma and I purchased a part for a tv and fixed it with your tutorial video. Thanks. Now I have a Sharp Aquos, LCD 60 inch. It powers on but only have a black screen and no sound.

[@JohnWest4]

KDL52EX700 Sony - Display is quite dim -but visble- and colors are distorted/remapped. There are no patchy/regional effects. Its done this several times, and then it would start working again - 100% perfect. Audio always works. Input from all sources are displayed the same on the screen. Going to split case to look for leaky caps, sniff around and look for damaged components.

[@chrishulley3698]

My Philips LCD TV took a power hit a couple of months ago. I took it to a repair shop and they replaced the power supply. Works great, except now it won't find any digital or analog channels when I perform the Auto Detection (antenna source). I have a couple of smaller LCD TV's in the house and they are picking up digital channels (antenna source) just fine. Is there another part that I might need to replace to get it to find the channels?

[@dennisdrevna5533]

Great video. I just acquired a Sony LCD TV model # KDL-52xbr6. Every thing works OK on the TV except the picture is dim and heavy on the colors after it warms up. any suggestions.

i have a sony XBR48X800E that does not turn on.no power at all.no red light either.i checked the power supply cord and it has power. i changed the power supply board and still no power.i suspect the main board, any suggestions?

[@jasminscott8434]

WOW finally an actual professional 👏.

[@bobbrock4221]

I just replaced my mainboard on my CX after my television was randomly freezing and making a horrific siren like nose until I unplugged it. It would also randomly freeze without the noise and I would have to unplug it to get it to work again. I ended finding a lot on eBay containing a used like new mainboard, power supply, wifi module, power button, and screen board for only $75. I couldn't believe how cheap I got all of these parts for; $75 for a $291 mainboard is a steal. I got really lucky finding this deal. My tv works fine now and I have a ton of backup parts as well. Doing this myself saved me around $500 to $600. The hardest part was moving the tv out of the carpeted room and into a room without carpet.

[@xkeithx2]

based on this video looks like i need two replacements ill check them thank you see i had picture problems first and then the tv wouldn't turn on that sounds like its a power supply and a backlight issue together Vizio E470I-A0 is the model

[@lesegolekhoathi7126]

Hi Guys thanks for the great videos, they help lots. I have a LG 60la8600 and the screen just went blank the other day, i had one of LG's techs come check it for me and after paying a call out fee he told me my T-con board (P/N 6870c-0445a) was damaged. asking him where can i get one he told me i couldn't get it separately as it comes with the screen, only problem is the screen cost more than the price of the TV itself. I then started my mission to find alternative repair options cause only 3 years ago i spend close to $3000 for a brand new TV and now i must use it as paper weight. after months of searching i finally found the exact T-con board for my TV and the seller was kind enough to give me two of them. excited i then installed my new T-con and boom no change still no picture just a slight glow as before, tried both T-con and same result. i then wondered if its possible that the problem is something else maybe the main board but though i may end up buying all the parts in my tv so maybe look help instead and that's how i got to your channel. needless to say I've tried your website lots of times but get an (access denied error) don't know why but maybe you can help me with that too. but preferably please help me first with a diagnosis of my LG's problem. maybe this is important, TV has sound but no picture and when i press the menu button on the remote i can see something is happening on the screen in the form of the glow intensity but nothing other than that. please please help thank you

Hi, I am Mojammel Rahaman from Kolkata, India. I have Sony KDL-32EX720 3D TV, Presently my TV shows some vertical white lines right along any subtitle or TV channel logo. As it runs for few hours the screen becomes almost white like it could not able to refreshed that white lines, and then the hole picture freezes but sound continues as it is. Sony service engineer said it is the problem with the LED panel, However, local engineer said it is the problem with either T-Con board or Main board... What should I replace.... Please help me.

[@ShuswapBCPortal]

hey Jimmy, we have a fun one. our 4 year old thought it'd be fun to spit water on the screen. now the screen has no display, but there is sound. I took apart and can confirm the backlight is working. seems like the t con board, but it did not get wet. before I go and buy the part, wondered if you have any thoughts on what else it might be. thanks so much!

[@louisj.mccabe1176]

Thank you for posting such informative videos. There is so much garbage being posted on KZbin and it's nice to find logical/intelligible information.I have a Sony KDL-52NX800 tv which works fine at cold startup. Once it is warmed up, vertical lines begin to appear and/or the image begins to scramble. Audio is fine and all inputs have been tested and seem to work. Any ideas please? Based on what I've viewed with your videos, could it be the T-Con board?Thank you in advance!!

[@mournetv6616]

Hi great video... I have a philllips 49inch 4k tv ( 49put49000/12) that has been barely used and just didn't turn on one day, is there likely to be a replaceable fuse inside as ive checked all the external fuses cables and outlet supply

[@pakachakawaka]

I want to make sure im hearing it correctly, the name of the board that is welded to this particular model is called the T-COM board, or is it the T-CON board? Secondly, I have a Haier LCD 32" and placed exactly the same way on your Sony but it is at the bottom of mine. How do I know that it is welded there, and not by other (removable) means placed there?

[@Dramaguiness]

Hi I have a Sony KDL-26U2000. I plugged my active speakers into the aux socket of my TV to get the sound of my TV to come through my speakers, when I turned off my speakers the TV went black and turned off. I have checked the power output which is working fine, the fuse in the plug for the TV which is also okay in other appliances. I took the back off the TV and tested the fuse inside the TV which also works fine. What is the solution? Is there more than one internal fuse? Thanks!

[@jamesmallett2232]

I’m troubleshooting a Sony KDL-40V2500. According to your video I leaning toward a backlight inverter. I have changed the power supply board already but that didn’t solve the problem. When you power the set on the picture and stand by light shows for a second, then picture shuts off and the standby light starts flashing red 4 times. Any suggestions! Would trying backlight inverter be the next course of action? Thanks in advance for any advice.

[@LeGrandZas]

Jimmy, just like you've asked us to send you questions, I did send you one but did not get a response. One of the 6 plastic connectors to the scan board is unglued and I don't know what to use to glue it back to the board without messing things up.

After watching this video I purchased a T-Con board for my LN46A550P3F Samsung TV. The problem is the TV does power up every time, however most times I only have Audio and no Video. On occasion the Video will come on and stay on as long as the set is powered up. If I power off the TV it may have video next time I power up, but chances are that it will not have video. I keep turning on and off until the video appears. If the video does go away the sound remains working. Can you recommend a solution to this problem? Thanks Phil

[@Soundbasics]

I have an 80” Sharp LCD Model LC-80LE650U…the TV won’t turn on and has a short flash followed by long flash..in my search I have found this to be an error code for the backlights. How do I diagnose this as replacing the backlights on this is a taunting chore. Could replacing the main board fix this or power board? Is there a converter board on this big screen? How about a reset sequence? Thanks in advance!

My Zenith Z50P3 \ Model: 50PC3DB lists all the "Input" jacks on the screen from which you choose your device. The listed jacks are grayed-out when not in use, and lit when in use. The two HDMI inputs worked until recently. Both inputs still light-up when viewed under the "input" listing and in use, and grey out when not in use, but the screen reports "No Signal".

Hello. I have a lg 42lk450. About a year ago, hdmi 1 and 2 stopped working. HDMI 3 still worked, so I have been using that. The other night the picture went out. The sound was still on crystal clear. After a few minutes, the picture came back on. It kept doing that. I took the cover off to find all the board numbers, which I did. My question is how do I know if this problem is the tcom board or the main board? It seems when I took the metal plate off the tcom board, the picture stayed on longer. I also tested the hdmi ports that weren't working. One port got source not found like it did. The other hdmi port had the blue screen that I now have been getting when the picture goes off. The Tv has back lights as well.

[@shopjimmy]

+courtney bush Try all repairs and troubleshooting at your own risk. This sounds like a TV panel (TV Screen) problem. If your TV panel is bad, it may be more cost-effective to replace the TV as panels are typically hard to find in stock, difficult to replace, and expensive.

Hello Jimmy. I have a Sharp Roku LC-50LB481U LCD Smart TV with no back light but the image is there when shining a light on the screen.

Hello ShopJimmy. I have a Sony Bravia 55BX520 with no sound, no picture and no indicator / blinking lights on the front of the set. The set is dead. I made sure the wall outlet was working and tried the little reset / check sequence on the Sony esupport website to no avail. I then pulled the back panel and checked the main fuse on the power supply board with my meter, fuse is good. Btw I can hear a relay energizing type noise from the power supply board when I plug the set in. After I verified the fuse was good I checked the 12v & 24vDC output voltages at the pin connectors on the power supply board and those were present as well. At this point I would like advice from you concerning my problem. I have a feeling the main board is shot but??

I have a Sharp LC-50LB370U I have sound and can see the image with a flash light. Based on the info in your other videos this tv has everything built into the main board. When I open the back I see the t-con board, a main board, and the board that holds the various inputs. I suspect I would have to replace the entire main board. Am I missing anything? Are there backlight inverters somewhere that I am not seeing?

[@JacobSMueller]

Hi, I have a LG TV; MO.- 32LC5DCB-UA. The TV sound works but the picture went out. I'm guessing its just the backlight inverter board, but wanted to make sure its not the T-COM board or something. (don't think there's a T-COM board on this TV?) Haven't been able to try the flashlight test yet, because the tv at my other house, but if I do and see a faint picture would this point to a faulty backlight inverter board? THANKS A BUNCH!

Hi, thank you for your video. Very helpful! I have a TV set LG 37LK430. It was pluged-in to a multisocket but was on stand-by. I was plugging in into the same multisocket another device and a short circuit occured and the something in the TV burned. Now when I plug-in the TV the small blue control light comes on for 2 seconds and then goes off. I checked the fuses on the power board and they seem to be working. Could you give me some hints what to check. Could this be something else apart of power board? Many Thanks. Christophe

I have a Samsung UN65KS8000FXZA (Ver. FA01) LCD TV that just developed a brown vertical line at the center of the screen. The area where the line is, appears to be dark, like a LCD has failed, but I am not sure. I would like your opinion on the failure mode. Is it possible that the dim (or brown) area on the screen is a function of a failed LCD strip? I also looked on your web site and noticed that there are three LCD strips listed for my model tv. Is there a way to confirm which Samsung PN is in my TV ? Thank you for your support.

Hi guys, hope u can help me. I have a Sony kdl60r510a I don't see a serial #.. my issue is a large dark area covering most of the right side. U can still see the picture there but like it needs a light shinning on some parts. I took off the rear cover and the backlights all LL ok to be on in that area.... I'm stumped now

Ok so I have Sanyo DP42740 that turns on and then off after a few seconds, I thought it was the power board so I purchased a new one and installed it. It still has the same issue as before, should I purchase a new main broad to solve my problem?
