Question about Samsung LN32A550 32 in. LCD TV

1 Answer

Unit shuts down after 25 minutes

I have a similar problem. After 25 minutes on, the tv shuts itself off. This happens a few times and then after a few attempts, it can stay "on" for hours. I do not have the timer on but don't know why it is shutting itself down.

Could this be the lamp temp?

Can anyone advise?

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

Older-model Toshiba TV shuts off by itself


There is a large sand filled resistor on the main board close to where the power cord attaches that cracks. This will stop power until it cools enough to make the connection then heats up rapidly to open it again. It may be worth the trouble if you're handy with a soldering gun and can get the back off the TV. If not then I'd consider getting a flat screen.

Shuts down after 5 minutes blinks green


Once the set shuts down, wait for the unit to stop blinking. Once it stops hold in the input and menu buttons for 5 seconds. The TV will then give you an error code. A 6-1 or a 1-8 error code would indicate a bad Color wheel. Which I think is the problem you have.

Shut off itself


sounds like you might have an auto overvoltage shutdown circuit kicking in. The hivoltage goes to high and the monitoring circuit auto shuts down. More than likely trouble is in hivoltage circuitry. If you have a transformer that will allow you to bring up the set slowly without shutting down and you can look to see what's happening.

Intermittent shut off


20 years is too long and the components ternmial might be loose or crack at this time, I'll susgest you look for any dry cold solder on the main board and do resoldering to the components terminal.
