    Turn TV on has sound but no display also when I push the menu bottom nothing comes up on the screen. Has always worked fine just turned it on the other night and no picture

    TV image went black right in the middle of a show. Sound works fine...but I have no image whatsoever - just a slight glow to suggest the TV is on...versus complete black when it is off. I've checked my video connections, power, everything. I'm wondering if this is because I recently plugged the TV straight into the wall, instead of going through a surge protecter like I normally do. Any help?

    I have a LG DU-37LZ30 LCD TV purchased in Feb,2006 and on Oct 29, 2007 the picture did not come on upon turning unit on this evening. Sound was normal but no picture upon using all inputs including the menu function. Totally black screen. Can you indicate problem. LG says TV is out of the one year warranty. Have unplugged unit and plugged in the next day to power up and have the same problem.

    I have a Dell W4201C... 20 months old-  same deal.  Was watching it- went into the other room- came back later- all black but I still have sound and can still change channels.  When I power up, I don't get the blue Dell screen,  can't see the menu- nada.  Of course it is out of warranty.

    have a LG DU-37LZ30 black screen great sound, tried resetting but no good. Sent to a repair center for evaluation and they said it needed a new inverter main, invertor slave, and digital board. $511.97 in repairs not covered under warranty. I am fighting with LG to get it covered. I can not see why this would happen. I have a whole house surge arrester and a secondary power conditioner for the TV. No other problems with electronics in the house. Can you suggest whether I'm being snowed.

    I tried changing from antenna to cable on the input screen.

I have the same problem with my sharp aquos 42", to fix it seems like it needs to be reset. I unplug everything (all input cables rom cable box and also dvd player as well as electric), let it sit for about 30 seconds and plug everything back in.. works fine for a few more weeks and then it happens all over again.

The screen is completely black. you can hear sound but the screen is still black.

Try unplugging everything then unplug the TV for a minute plug everything back in turn on. It might be the main board that needs replaced on it if that wont work. FYI LCD TV/ DVD Combos have been known to have issues

Sharp Aquos 32 wont turn on

I called up Sharp, and if you are a part of Sharp AQUOS Advantage Program you get free in home service.

They were very nice about it, and I already have a technician coming to my house on Saturday and I called on Wednesday.

I doubt Sharp's policy alot less now!
