Your Y-main bd buffer(s) upper and lower. needs replaced. to do this, u need to remove the back cover with a t20 torx bit + phillips screwdriver. once removed, look to the far left, there are 5 or 6 long snap on connections they run along your Y upper and lower buffers. look at them carefully for burn marks around the sealants. if u notice a orange burnt residue, its prob burnt out and needs to be replaced. this should enable the video once again.

47" plasma 1080p ... screen went black , sound


Plasma TV's have a shelf life. By that I mean the screen is only good for so many hours depending on the model. Most likely, you have burnt out the screen and the set will need to be replaced. The good news is, plasma TV's used to be better than LCD but that is no longer the case. You can get a very high quality LCD TV for a very low price now. Also they use a fraction of the power and don't generate all of the heat of a plasma.I'm sure this is not what you wanted to hear but the reality is that ALL plasma TV's do this eventually, and it is something that most salesmen back in the day didn't bother to tell customers. If you have an extended warranty, you may be able to get it replaced.

My sylvania LC427SSX 42inch lcd. i turned it off and when i turned it on in the morning the screen is black, i can hear sound and if i hold a light up to the screen i can see an image


Hi,
It seems back light inverter is not working for some reason, either it is not getting volts from power supply board or got bad itself.
Please check with local tv repair shop for replacement back light inverter board.
Thanks.

Turn on JVC 32" flat screen TV and got the JVC logo then sound and no picture. Then next day, only got the logo, no sound or picture.


There is a way to reset television. I have a jvc 42inch that was just going to main logo screen and not beyond it. If i remember correctly you unplug the tv hold power button for 5 sec on tv then let go plug in and start. If that dont work unplug and then plug and hold power button on tv for 5 sec. It is 1 of those combinations. My tv worked after that. I googled my problem and a website listed that some tvs need to be reset.

Vizio GV42L 42inch LCD/HDTV


there are several possibilities. first if the unit comes on and the "VIZIO" light turns white, but no picture or sound, then the main control board is most likely the issue. could be the LCD control board(s) depending on model one or two. and ultimately could be the power supply on the upper side....if the "VIZIO" light does NOT turn white, the whole power supply unit is out. after that, would have to scope the circuits to find out. Seems that the control board is the most common and tends to happen on many different sizes. new board will be around $350.00. Might get lucky and find a used one, but it MUST be EXACT part or it wont work right. if you dont find one or want to sell yours for parts, id be interested in the screen. can reach me at kmarlin@grandvalleygolfclub.com. thanks, keith

The black bars are a common problem with these dells. My understanding is the warranty is good for two years. Be persistant with them.

It sounds like it's the inverter panel which lites the lcd back light.
If it's under warranty, try to replace it, or take it in for svc.
