Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

My Sylvania lc320ss8 shuts of by itself after being turned on for 1 minute or two, I have tried unplugging for 30 minutes as suggested by the owners manual but still shuts off, please help


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

I have a Sylvania LC370SS8 (37" LCD + DVD) TV. It will stay on for about an hour, then it shuts itself off. The power light flashes while it's off (for about 5-10 minutes) then it comes back on... and...


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

The tv turns on and digital tv comes up on the bottom of the screen, and then it shuts itself off by itself. We have unplugged it for a few minutes to try to reset, but it continues to do the same thing?

New TV 9 mos old, Won't stay on after power up? Remote or manual turn on, set keeps turning off after 1-2 second green on and brief screen flash.


I would try leaving the TV unplugged for 30mins so the TV can reset itself.
If that doesn't work, your TV should still be under warranty. I know 95% of come with a 1 year warranty.
The most common problem with Sylvania TVs made by FUNAI, the Backlight Inverter board fails to early in life. ( That's the part that powers the screen)
The Tv can't power up the screen and it turns off automatically. Basically called "Protection Mode" so it protects the other parts inside the TV.

TV goes out


Intermittent problems are the toughest to track down, but usually have one of two root causes. Cold solder joints are an intermittent contact between where a component (transistor, etc) is mounted to the circuit board and the electrical contacts of the board itself. The other cause is components which break down under heat. Either way, if your not much on troubleshooting, have a TV shop service it, it can be easily repaired.
