What do you think about this video?

ForgottenLegends OfTomorrow: yeah boy, fix that s h * t just subscribed

Dr Curious: my TV is - a RCA L42W22D. Power light blinks 5 red and no picture. any thoughts.

Nes Jr.: Thanks, it works for me! GreatJob ;)

Alex: **********CAUTION***********If you trying this at home you should be aware capacitors can hold a charge even after disconnected from the power supply and you shouldn't handle them directly without being grounded.

Dwight Sanford: i need my fix

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

For The Love of Blue October: 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.

shaelyn 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....

Chef de NYC: Thanks! I'm more info ultrasound type of work. I learn most of the stuff myself online. Just only recently start looking for a school to make things "official". Hehe
