Question about Televison & Video
Does anyone have experience with these sets ?
This one randomly powers on / off , sometimes after 2-3 hours , sometimes fine for 2-3 days !.
I had similar trouble with another set years back , this was repaired under warranty and needed the power supply board repairing .

Hi -I had the same problem with my tatung LDC tv. PIECE OF !@$#$#@#!!. Not knowing a whole lot about electronics, I decided well, I couldn't break it anymore, and I thought it was probably the power supply as the tv did NOTHING!!! it wouldn't light up make noise or anything. it was totally dead. I called around MANY, MANY local tv repair shops and NO ONE would work on this as they didn't have the repair parts for it. Thats what I get for going cheap. Anyway, well, I popped the back off, carefully making sure I knew where each screw went if I ever had to put it back together. Well, I located the power supply - it's pretty obvious, I removed it with a few screws and then found a company in california that repaired power supply's - I sent it off not knowing if it would solve the problem, but they quoted me $75 dollars and I figured if it didn't work $75 wasn't too much of a loss - and they said I could return it and get some of my $75 bucks back. So, I shipped it off to them. A couple weeks later, I got it back and installed it and to my amazement it worked!!! It has been working GREAT ever since. There is a few places online that sell the power supplies and offer a refund minus restocking fee if that doesn't work. Check out http://www.shopjimmy.com Good luck and hope this helps scott

Actually its a panel fault. You will need new inverter board for the panel. (That is if you get the power and sound, but no picture)

There may be some components failing in the power supply or one of the circuit boards that are causing too high a current pull.
I realize that this answer is very vague. Without doing proper diagnostics, it is impossible to guess at something like this.
Out of warranty repairs on these sets can be very expensive. I would suggest that if the set is going to be expensive to service, it would be best to replace it with a known brand name that offers an extended warranty with local service. You will pay more, but you will have dependability and better quality.

I just fixed a neighbor's by replacing the 2200MFD capacitor on the power supply board. Thanks for the help, worked great. If you replace it got for a 16V instead of the 10V and hopefully it won't fail that way again.
Just be careful and take notes when you're digging into it. And mark exactly where the card cage is before taking it loose.

You'll find some Samsung power supply boards here : http://www.usefulparts.com/index.php?main_page=index&manufacturers_id=11&sort=20a&filter_id=98&alpha_filter_id=0
but you have to open your TV first and find out model number

1 Check the antenna. Adjust it to see if the picture improves. Confirm that the antenna cable is firmly connected. Check to see that input cables are connected.
