Its actually very simple.If you can set-up a new computer you can do this too. It is just a bunch of connectors and screws. Take a picture of the wiring and then reinstall them one byone.

Sylvania Model 6632LG shuts down


Check power supply board and inverter board for faulty solder connections and visually inspect electrolytic capacitors for signs of stress or failure. Bulging tops, black or brown crusty material oozing out of them, are the most common. Replace those that are visibly faulty with high ripple current types.

If that does not resolve it, the next step is to test the transistors in the 24 volt section and inverter section primarily. Recapping the power supply 24 volt section is prudent regardless of physical appearance of the electrolytic capacitors.

Tv turns on and stays on for a 30 second then shuts down.


Hello,

You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some where,if otherwise the power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Hoping this will help in solving the problem....

The tv powers up for about 30 seconds and then the power light starts blinking fast and the tv shuts off i think it is the main board but any suggestions would help


Good day.

This the procedure that you have to do.

  1. Remove the cover of your TV.
  2. Power on the TV to apply voltage data.
  3. Check the power supply output.5vdc for main board supply,12v for the sounds and 24vdc for back-light inverter.
  4. If any of the 3 supplies are missing or got a voltage drop,there's a problem with your power supply.Check some leak/bulging top capacitor.
  5. If the 3 supplies are OK,the problem is on the main board of your TV.Replace it.

I hope this solution will be helpful.Thank you for using FixYa.Good luck.

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

When i turn my 42 inch plasma sylvania on, it makes a sharp high pitched squeal, then shuts off. it does this repeatedly, whats the problem, and how do i fix it?


You have a short on one of the drive boards making the power supply squeal. You will have to unplug each board until the squeal is no longer there. Which ever board it is will have to be replaced. Thanks for using fixya.
