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.
Also check for bulged capacitors, if found replaced with the same rating value.if otherwise Power supply board have problems,just not dead yet.Replaced the power supply board,will solved this problems.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.
Hope this works....

No picture, siren type noise as restarting


My Toshiba dlp 62hm116 was used for 3 months then stored for 2 years, I turned it on yesterday and it makes a loud grinding noise which I think is probably from the exhaust fan area and the picture is black except white at both vertical sides. It worked fine the last time I used it 2 years ago. Any ideas?

Tv keeps turning itself off


You most likely either have a faulty power supply or high voltage transformer that is failing. You can test them both with a voltmeter or multi-tester. The capacitors on the newer sets seem to overheat and burn out quickly
