L Schut: This is happening to my Insignia TV. It's only 2-3 yrs old. If I shut off my TV, then later turn it on to watch it, it won't turn on. The little blue power light is on, but my remote and the buttons on the TV won't work. I keep unplugging it from the wall, unplugging the power from the back on the TV, and nothing works. It usually will come on after 15 or so minutes of doing the same thing over & over. WHAT IS WRONG? Now I've had to tell my whole family NOT to turn off the TV at all because it's such a pain to try to start it again. Thoughts? I'd rather not have to go buy a new TV. Grrrrrr.....!
Robert Husk: Holy crap balls folks!
Wilbert De Kwant: Great !!
Synthematix: RUN A HAIRDRYER OVER THE CAPS for 5 seconds, if the tv turns on theyre bad, caps dont always bulge.
Zalatiel Velazquez: I ki
Shari Anton: Trying to learn now. Ugh. I don't know if I can do this. It's happened a few times. If I turn the TV off the only thing that will turn back on is the light. Just a black silent screen. But, if I unplug it and leave it for a while then plug it back in then I can turn it on. Sometimes it takes more than one try. So I'm sure something is going out. It's only a couple yrs old dang it. BOO
Derpy Destroyer: ok here is the thing i got an xbox one wake up today decided to play gta but my tv turns on but the audio i tried turning of and on wich worked yesterday but it doesnt work please help me!
Snide Pete: Very nicely done! I have a background in electronics, but I'da never thought it could be so simple to fix a hi-tech big dollar item like a 45 inch flatscreen! Just goes to show ya; never give up! I'd like to add that caps are polarity-specific, so you need to be sure to put the + lead back in the + hole, etc. And I'd also add that it's very important to replace each cap with the proper value. Maybe replace them one at a time so's they don't get mixed up. All in, though, a great article, thanks a bunch!
Jason Arcos: he sounds like vin diesel
james donnelly: great info mate thanks the reason my tv is not working is the cops raided my house looking for the crown jewels and flooded my house now thirteen years later the house is stinking with dust and dampness and so is the electrics go to u tube and watch my stoy its true its under thei on u tube [THE PRINCESS HER MOTHER AND THE FALL GUY ]original JD.
Sawgrass68: Holy crapballs is right. Had a Palsonic TV that wouldn't turn on. Did exactly what you said(had 4 caps blown). Fixed for $5.25 in Aussie. Legend thanks.
PWNAGElNC: Just thought I'd throw this in, if you don't own a soldering iron and are going to spend around $40 at least doing it this way, you can buy that entire power supply board for somewhere between $30-$40. All you'll need for that is a screw driver.
bill miner: ill just get a new tv
Celeo Portillo: OMG! I have the same LG HDTV with same issue. Will try to fix now. I was going to toss out in two weeks. Thanks brother!
Geoffrey Morrison: Small local electronics parts stores don't exist anymore--maybe in some major cities. RS is toast. I didn't see bulging electrolytics: I wonder about the internal power supply. I'm not now likely to buy a refurb mainboard for the smaller 26" LCD TV (the part maybe still goes for about $75, if it still exists--that's about the value of the TV, used and nominal--maybe even more--that's just not reasonable). Fixing it is pretty low on the totem pole.
FI--just get new and recycle. I hate to see my broken TV simply being shed like that--given the great efforts necessary concerning development, components, fabrication, logistics, marketing etc.--and problematic disposal--not just purchase costs. Flat screens seem almost miraculous. It looks practically new and shiny, still....
More concerted and organized efforts towards documentation and instruction prove warranted--we can't just rely upon simpleton pay advice from TV techs online anymore. It's often hard to divine exactly what's wrong. Things are improving--more content here. It's certain that some DIY'ers with broken big screens like this will attempt valiantly, still....
Katie Pace: Thanks for your tips! We just fixed our LG for less than $40 because of you!
Tony Brown: only replaced the burnt out 1 and works fine thanks for your help
jyoti sharma: Hello, My samsung LED tv has a similar problem. When I switch on the TV I can see no image just a blank screen appears but the sound is perfect. Is this related to capacitor or do I need to change the screen.
