Can you still turn it on?
If so, does it stay on with sound?

If the sound is ok and the picture is blue (even when changing channels, inputs, etc.) the lamp may have gone out.

Can you see the TV menu when you press the menu button on the remote or TV?

My Sylvania flat screen sound keeps going off


Check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Pull up older posts. Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts. http://electronicshelponline.blogspot.com/ The most probable cause is with its audio output IC itself; overheats.

Dear Support, This is about a 42'' Sanyo plasma HDTV model no: DP42746. It's my mom's, and at ''84'' it's her window to the world. So it needs to get fixed, please help! It was working fine, then all...


Hi Ed,

The only thing you can try is leaving the TV unplugged for an hour so the TV can discharge and reset itself.

If this doesn't work, then we're talking about maybe a power supply board problem for the screen itself. Most manufactures call it a Blacklight Inverter Board. I would use the warranty for the TV if there is any. The TV repair shop maybe expensive for this type of repair. So, get a price quote first. That way you can decide if is easier and cheaper to buy a new TV for her.

Samsung T.V. goes on for 30 seconds then no picture


If this is a flat panel LCD tv, this is a sure sign that the panel itself is bad. I have seen this before. Tv comes on works fine then within 5 minutes goes blank.

TV has sound but no picture...


This is a pitcure tube problem, either you buy another picture tube and change it on your TV or if this is under warranty better to send it back to the manufacturer and have this one repair.

TV turns itself off after a few seconds, no picture at all


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

DLP tv trouble shooting


Hi.
Yes it could be a cooling problem, If your tv has any filters remove & clean them ensure fan can turn freely & that nothing can or is snagging it.

Picture


yes it could ba the cable itself even, but i suspect more the tuner circuit or tuner itself may have bad solder connections. Here is another test for you to try, plug another dvd or vcr, or xbox etc. into the back, using one odf the inputs. See if this works like the built in dvd. if so it will be more likely bad connections in the tuner or surrounding circuit. good luck.
