Samsung TV shutting off by itself and relays clicking


If you don't know what you're doing, don't open it up to fix it!
There are HAZARDOUS voltages on the power supply board EVEN WITH THE TV UNPLUGGED!!! The capacitors can hold a charge for several weeks!

Clicking noise can be coming from bad capacitors on the power supply board.



It's usually easier to just replace the power supply board.

We have the RCA HD52w59 projection tv. The tv shuts itself off at different intervals. It takes approximately 1 minute to be able to turn the power button back on, however, I have to do that many times...


A problem in the deflection board. Could be a Cap. Resoldering the deflection board may take care of the problem. You need to call a TV man to do this kind of work.

Best of luck

Screen freezes and then shuts off. This cycles every 1-2 minutes


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

Try the main board with the cpu chip. The cpu chip should have a heatsink attached to it, may be an overheating problem. It has the LCD panel connector plugged into it. You may be able to find the board on ebay for less than a repair shop.

This is a sign of a failing capacitor set on the power board. there may have been a small or minimal pulse that went threw the set during the power outage and when the power was restored. this could also be overheating as well due to dust forming on the power boards components. i would remove the back cover and clean as much dust off the power board as possible with some sort of canned air if possible. make sure the cooling system is working properly as well.

please rate and god bless.
