SOURCE: Screen has gone black

This thing's gotta go to the shop. Don't poke around back there, very high voltage. Check around for a reputable tv repair shop. If it's real heavy, maybe you can find someone who makes house calls?

From your description it sounds like your TV it's actually on you just can't see a picture. That is usually caused by your Zustain boards. The zustain boards are located on the left and teh right side of the TV. You can check the fuses to see if one of them is blown or you can leave it on and see if one of them does not heat up. You would have to replace the board. You can find part at www.interliquidparts.com

SOURCE: The screen will turn on, but after 2 seconds the screen goes black, the power button stays lit, and sound remains. What could this be?

it could be a bad CCFL lamp, inverter, power supply 24vdc output, or a main board problem. The set will need to be properly diagnosed.

I have snow on a black screen when nothing is on.It is a LG 42PC3D I still have a picture when I hook up my HDMI. How do I get rid of the snow.


Sounds like your y-sustain board is getting ready to go. You need to have a shop replace it along with the z-sustain board to fix it. Hope this helps.

My coolpics s6 has a black screen when in picture taking mode - as if the lens is not open. icons display, and show pictures mode works ok.


Switch on the screen in setup. The screen is now in 'power saving' mode and does not lit up while taking pictures.
