ken wahl: I have a RCA L42WD22yx6 serial I134CU036 First experience; would have to unplug to turn on tv, red light blinking, no green light. So other than unplug and replug no problem.

Then no picture 3-4 mos. later. I took power board off changed 1 swollen cap 1000uf35V. reassembled came on good with green light working properly but still no picture.  I simply plugged in, powered up with no input source. I expected to see a "Unusable source"?? floater hoovering across screen, I got nothing. Heavy Sigh...

So i dug it open again and took out both backlight inverter boards, they appear to both have 2 caps on each with tops looking a little raised. So I suspect they are all 4 bad. But not sure. Main Board "Looked" fine as far as caps go. 

Any ideas

Dale Dietsch: 63 inch Sony flat screen televisions replaced bulb about a month ago it went out again any idea

Paula Sutton: We have a LG 32LG70 LCD TV. Last night, my husband was watching it, all of a sudden, screen went white and no sound. No power surge. Have taken back off to look for any possible scorch/burn marks, none seen on first inspection. Could this be the capacitors? Also there is a tiny white fuse on that same board, appears to look okay. Don't have volt meter, to check.

Jabaar Dugan: I have a LG 47LW5600. It powers on and the LG logo fires up. After that it does nothing as far as showing television. I had a tech tell me it's the graphics card. Is that accurate and if so, where can I buy one and how easy is it to install.

bull smith: I have a 47LE5400-UC and the screen is lit, but no picture, even in menu,or sound. There is a response from the remote, but only static when I volume up and down ?

Danny Ortiz: The same thing just happened to my TV today. Its an LG too. The only difference is the screen works when it wants to. I was watching TV and screen went black but I can still hear everything. When I turn it on the LG logo just flashes for a quick second and then the screen goes black again. I had to keep turning on and off the TV several times for the screen to come back. I'll probably just get a different TV. 

Rick D: I have a RCA 32 inch it has no sound or picture ! Just a light blue screen can it bee capacitors ?

Burhan Karimy: Hi man I'm Kurdish from Kurdistan how many USD fix that LG please Reply me ?

Chip Carrigan: Excellent! I bought the repair kit for $12.65, and replaced 5 deformed capacitors yesterday, and voila, works like new!
Tampatec, your the MAN!

Henry Reyes: I'll try it. I'll let you know if I can get it fix.Thanks Teacher.

B Reid: You should probably explain that the bigger caps on the hot side can hold there charge for some time :0   bud nice vid though .
Also for the love of all things AC make sure you unplug your TV not just turn it off!! trust me mains voltage does not feel nice...
