[@ricardonunez1602]

I like how you describe in detail what are the most common things that will go bad in a tv. I would like to learn more on how to fix tv's.

[@foodprude9700]

I'm an amateur so this helped a lot. Thank you, TampaTec!

[@Brucefan60]

I was wondering what your background is. Normally, I would have thrown my TV out that went bad but thanks to your videos I was able to fix my TV. Thank You!!!!

[@quest1221]

Hey Tampatec just wanted to give thanks for the I go on te vizio phone number I contacted them and yes my tv is still under warranty they will b here next week to fix. Thanks so much. Keep up the good work.

[@fred306801]

This is one of your better videos. I like the way you go through and test one thing at a time. So cap's and batteries are more a like than I thought. From what you said "Cap's can go bad just over time". So it's kind of like flash light batteries sitting on a shelf. You go buy them and they are already dead. So have you ever bought a new cap. and it be bad ? You said you thought it was a bad transformer on another board. And it was best to replace both. Is that because you think the board with the transformer may be bad as well ? Sorry if this sounds silly or what, but all this is new to me.

[@TampaTec]

yes when in doubt change it, inverters have transformers that go bad commonly and take out other parts. you should check out The super capacitors they are the Future!

[@flutemen]

Hi Tampatec,i watched two video's of yours tv repair for beginners and easy way how to test caps diodes etc etc, found them very informative and interesting.I need to send you a few pictures of my power supply board and a component with text and stuff how can i do that. then i can explain my problem with my television.thank you.

[@THOMMGB]

Hey Tampatec, Thanks for doing this video. I'm still learning the basics and your video helps to clear up some of the fog. Regards, Tom

[@victorfeliciano1961]

Crystal clear info. THANKS!

[@frankebenjamin8114]

Thanks for the information and I hope you continue to prosper.Quick question,I have two tv. A 40inch Samsung that bumped against the wall and have vertical lines no pictures, and a 50 inch RCA that had virtical lines due to a cereal bowl. I'll I have to do is replace the panel right?

[@Allessio777]

How can you find out what the blinking light codes are for your TV?

[@MehmetSuatMorkan]

Hello Tampatec. thanks for your videos. they are full of information not just crap. My neighbors TV got broken instantly while they are watching. I checked out and there is no sign of living. Its a 47pfl.... Philips tv. It has a dps 298 4 amps power board on it. I checked out the output voltages. All of them is showing 0 or very close to 0. I checked all diodes. Two of the diodes are shorted. They are parallely connected. I thought may be there is another connection that makes them short. Removed them from circuit measured them again, 1 of them is completely short other is sometimes short, sometimes 200. They are labeled as SB260. I don't have any, also in my country there is no. I think they are 2 amps 60v diodes. I have two questions 1. which diode can I replace instead of these? 2. Do you think that replacing will solve the problem? Ps: I don't have anything to measure capacitors but they look well (no pop, burn etc.).

[@chrismooney4228]

I've watched a few of your videos here. They are very informative. Thanks for doing this. I have an LG 50" Plasma model 50PN6500-UA.BUSLLHR. It's 2.5 years old. For the most part the TV works fine but after it warms up, if you play with the volume or mute buttons on the remote it shuts off for a couple of minutes then comes back on. I called the LG tech support line and they said they have not heard of this exact problem before. Have you ever run into this problem. What board do you think will need to be replaced?

[@acsmanny70]

thank you for ur time to show us. on how to repair our tv. love ur video ever sense I am been watching ur video I want to learn how to repair then....nice work bro....

[@briankanyinge4205]

thanks man.well explained for beginners.

[@dcjrtv]

nice tech

[@colintran6876]

I appreciate your technical expertise for showing how to repair tv but would you let me know where to find part for replacement. Thanks😜👍

[@PerrynBecky]

Makes sense. Sometimes what one sees is the effect, not the cause of the problem. I worked on cars for 35 years, and I've seen one thing that failed only to find out some other component would get cooked too. I can't tell you how many times I have seen someone replace a burnt out component only to have it fry the moment they turned the key because they went no further than what was in front of them. Example: GM has a control module that controls the fan speed to the HVAC system in the car, and when the fan starts to draw a high amount of resistance due to wear on the brushes and armature in the fan motor, it burns out the control module first before it stops working altogether. The fan still works like normal, but because it draws more amperage than the module can tolerate, the module burns out, and the fan stops working. Many techs will replace the burnt out module, the fan works again, but a week later the new module is fried again if not right then as soon as the tech turns the key depending on the amperage draw. Sometimes it takes replacing multiple parts to repair problems. Thanks for the presentation.

[@franzthesee1702]

Very instructive, thanks a lot !!

[@mattklaver3563]

My Samsung flat screen tv's picture has a shadow that is very appearent when using the station guide. When you play a dvd it's nice and clear. I've already replaced the cable and the cable box itself. I think it's a faulty cable connection port. Have you ever heard of one going bad if so what would be the fix.

[@docifun]

I have a Samsung 32" (2008) LN32A450C1D model that has lost color. Regardless of being on cable or antenna the picture appears in a negative view. The images defined & sound is good. The TV indicates it has a weak signal, however it had been working just fine. Other TVs have been used to validate the signal with no problems. It appears to point to the Ant in portion of the TV as the problem. What do you suggest? Thx in advance

[@Krazykarllsound]

Very good video, mon!

[@69snoopster]

Hey Paul. i just ordered and replaced the powerboard (sony a-1660-720-B ip1) from shopjimmy.com.) it's for a Sony KDL-40v 5100. before, there was no power on light. now, i get a green light, but nothing on the screen (at all). what video should i watch to get to step #2? i can call, but i thought i'd try this first. thanks

[@PsnPrez18]

Hey do you think ita possible for you to tell me what part is the "power supply" in a sylvania LC407SS1? I need to purchase a new one due to a power surge in the house. But I do not know which part is the actual power supply. Thanks!

[@niteowlsully2266]

thanks for all of your vids you helped me get my TCL running again. however i still need help and i hope you can guide me. i have a TCL 40fs3800 that is 1 year old and i just replaced the main board in it. it doesn't work correctly in that the picture is upside down now fuzzy and snowy. the colors are messed up also. can you help me out? this originally had a solid red light and no start up from manual button or remote, i shined a flashlight on the screen and saw nothing. then took it apart looking for obvious problems such as caps and burn outs. nothing... so it didn't take but about two seconds to see the power supply and main were all one so i went and purchased a used one online for $15 and replaced it. now it turns on but video is not right. got any ideas?

[@youngerwong204]

I learned something 👍

[@jennamccune]

i have a vizio e371vl that isn't getting any power due to a power surge. i have replaced the power board with a new one i purchased off of ebay and still no power. any ideas? or am i just screwed?

[@thomaswstorm]

thanks on the voltage reg. it seemed a bit flakey so I looked for one. Digi has none. Poland is the closest place.

[@thomaswstorm]

+Thomas Storm got the regulator, installed today, you the man. may i donate to your support when it sells? PM me. thanks. funny story for all to learn. i fired this up. went to program in the AIR as i dont have cable. as it was programming i installed the back. a minute later smoked pored out the back. big time. SHUT DOWN. removed the cover fired up again all good. POINT IS, always clean the boards after reworking.

First, I wish a Happy New Year to you. Second, Great job buddy. Third, I've a Toshiba Ragza 55" that I bought on 2006 as a Christmas gift to my parents. They are Not used it too much. Recently, they tried to turn it on, but there is No picture, No sound at all; however, the power supply is working fine and still flashing. I do not know what is the issue. Can you help me, please? Thank you so much.

[@jeffreyhunter8223]

I'm a "Green" beginner ... but I have a "LG" LED flat screen TV and I'm wondering about fixing it should it happen to need fixing? Have you done repairs on "LG" products?

[@thomaswstorm]

Hi Tampatec. first off thanks for the vids. i have watched all of them over time. i also refresh when i have an issue like now. The Fizio board you are working on here is from a vo47l, or close to it. It looks the exact same. Question. all caps are replaced. the cap blown in the vid must be a common problem. I have stanby volts and less than 1 volt going through the 24v lines, 0 v turned off. it comes out of standby but does nothing else. the relay is clicking. i tested the bridge rect and it tests good. what video do you recommend for further testing or what parts would you test next? TIA thanks stormy, student extraordinaire

[@TampaTec]

Check voltage regulator.

LG37LC2D powers on, have the Hopper hdmi hooked in- then after 10 secs it filters through all input sources and then shuts off , turns back on by itself and will do this until I unplug it. Can you recommend anything?

[@MrObrien205]

I have a sylvania 6727 FDE triple combo, it keeps jumping into this mode where there is a black rectangular small black box in middle of screen shows BF -0.22 with four number 2's in each of the four corners of screen, knocks out the sound but leaves the channel and picture on screen

[@freeyourmindok]

If you say the board needs to be replaced because it has bad trace lines why keep testing. On replacing board do you have to replace all parts to new board?

[@jboscoe]

since you are into the repairs do the manufacturers build these units to fail. Seems to me a lot of board have bad capacitors. Where can i learn to troubleshoot and repair these units?

[@greenmarine5]

[@rogertyler3237]

I Have A TV My Neighbor Let Me Have & Wen I Plug It In I Get A Standby Light But No Picture Or Sound. So Could It Be A Logic Board Or TCON Board Or An Inverter Board?

[@PAULWONG328]

I had unplugged the T CON and it still turn off on itself. Power board visually has no bad capacitors. So is there a way to check the main logic board to confirm it causes the problem?

[@stephenmarkle9267]

how can i trouble shoot my sanyo 42" plasma? half the screen is out. i think it may be the T-Con board but i am not sure. do you know how i can test the T-Con board?

Hi i have a vizio model M3D650SV the tv will turn on and stay on for anywere from ten minutes to twenty five minutes picture and sound work fine after it shuts off on its own you wait 10 seconds hit the power button and the tv will come back on and play for another 10 to 25 min wait 10 seconds and you can turn back on again and you can go all day doing this power supply in is ok tested that even moved to another power outlet i opened the back of tv nothing looks bad no bunt smell no burn marks what shoud i look for next

[@gtmx1411]

My Panasonic Viera tv was not used for 2 months (Model number: TH-42AS670D, 2014 model). I face the following issues: 1. When I power on the TV it goes to home screen (default). 2. If i click any icons on home screen, be it Media player or KZbin, it just freezes. Then screen blanks out after few seconds, and navigates back to the home screen. This happens even if I power ON the TV and do nothing. 3. None of the REMOTE buttons work except the power (ON/OFF) button (same happens when i use the android tv app). Same issue with the TV UNIT buttons too.. 4. Most importantly, if i invoke Main menu on the tv or remote or android app, it doesn't show the menu at all! 5. I tried a factory reset using tv volume- and remote Menu buttons, still above issues persists. 6. The firmware update does not run from USB, since I already have the latest revision installed. I have taken apart the TV back panel, and haven't noticed any capacitor burns or loose cables. Is there a way we can do a forced firmware install, if that fixes the problem.. Would really appreciate your inputs!

My name is ART. I have a Sylvania 6727 FDE CRT TV. I hope you can assist me with this bit of a dinosaur. When I attempt to turn on the set it clicks once and does not come on. This is a TV that we would love to keep going as it also has a DVD player and VHS player. I was given this TV when I acquired a property about a year ago. It has worked until recently but was very slow coming on and getting a Blurr-Free picture.. It has been used outdoors since its purchase. We were told it was an "outdoor unit"? It is mounted up high under a covered roof and it is not subject to direct water damage. When I do use my remote to turn on the TV I see a very quick little green lite then immediately it turns red then immediately shuts down. I do NOT have any manuals whatsoever but would like to obtain both the repair manual and the owners manual. Would you propose that my issue is a Power Issue? Could you also direct me to the manuals? Regards, ART

LG 46LD550-UB Has green shadow on left side of screen or picture about 15". This happened after I put a used main board from EBay. before put the main board in I had nothing. after I put main board TV played for a few minuets then the shadow came on.

Hi I have a Samsung Surround DVD player Model HT-H5500K, Model code HT-H5500K/XA. This is the only appliance that I Earthed until one day a Lighting Storm struck, at the time the TV and DSTV decoder were also on but nothing happened to them. When the lighting struck hit us it tripped the earth leakage and that's the last time my surround system worked. After inspecting it inside I cannot see any burned damage or smell anything that has burned, yet a company that I took it to for repairs tells me it is unrepairable and I don't believe them. Can you advise?

I have a lg42le5400uc. My baby sprayed it with water and one of the ead's went bad (tjick grey line on screen). I replace both sides but was rushing and switched by mistake witch caused one to burn. I just replaced both again but now I have no picture at all. It turns on but no LG ico, etc. Should I replace the driver boards or the tcon board first? Thanks in advance if you can assist.

[@TampaTec]

my guess is tcon board cause if water dripped in tv edges it maybe shorted.

Hi. I have a Samsung Plasma TV (PN60E550) that is giving sound but no picture. The problem has slowly gotten worse and worse. For a while after several attempts the picture would finally come on (and often while on and working the red light would blink), then it took a lot more attempts and now it just won't generate a picture at all. I watched some of your videos and opened up the TV. None of the capacitors appears to be buldging and there is no obvious damage or corrosion anywhere. So what is the next step? I don't want to remove all of the components and test every single thing .. how do we narrow the problem down to one component from this point? Any help is very much appreciated!

[@marmarteeny]

I just watched your samsung plasma tv video and I wanted to add that I tried unplugging the y board and checking to see if the tv screen would come one. It did not. So that means the issue is not the Y sus board right? I really don't know anything about this kind of stuff total noob so I don't want to dissassemble these boards to test / replace all the caps. my soldering skills leave a lot to be desired. Please let me know what you'd suggest from here. thanks

Please help.. how I explain well enough for u to understand. Thanks

some tv tuners are better than others, use amplifier but sometimes loose connections on connectors can cause weak signal and bad solder connections on tv turner board can weaken signal, (make sure you use rg6 cable)

[@Leoj-dx2nv]

Quick question... If a capacitor it suppose to measure 47 uF and my meter measures like almost 2,000 uF from that capacitor instead 47 uF does that mean that the capacitor is bad as well? Reason for my question is because it already happened to me when I was measuring my ps3 power supply board and all the capacitors measured pretty closed according to each range in each one of them but except the only one that I'm mentioning above. I'll wait for your response Thanks in advance Regards

[@TampaTec]

take cap out of circuit and read it, check meter settings and put in fresh batteries in meter too then check it again, but when in doubt change it out. ps3 usually main board goes out first.

I went over to look at the TV and took off the back to get a look at the power board and nothing looked out of the ordinary visually, such as blown capacitors or burt marks. I also checked the fuses and they were ok. So I advised to order a Power Board anyway since the TV would do nothing. He did and just tonight after replacing the power board, he said the same thing. NOTHING! I was like "not even a sound, or a power light?" and he said nothing. Tomorrow I am going to look at it with a meter and all. What can I do to troubleshoot this baby? I may, like you suggested check the Test Points first and than start disconnecting the loads off the power board. Is this a good idea and if so where to start? Any feedback would be appreciated. Thanks Michael

if you got 3.3v or 5v on power board then main/video board is bad which is common for a strike, when lightning hits the ground it travels through cable lines then in cablebox then through hdmi cable that is connected to TV, but sometimes it travels through powerlines to TV's powercord to power board Or taking out both boards sometimes- get parts at shopjimmy.com/ or 1 [phone] / [phone] 8^(

Hi Tampatec, I hope you could find a second to help me... I'm trying to fix panasonic tc p50st30 it won't turn on. The led light is on but doesn't blink so I took back panel off and there isn't visible damages I mean nothing burn, all capacitors are look good but I did not test them since I don't have tester. What could it be? Thank you!
