Re: no power no picture no sound
I would say that its time to put that tv to rest is it a projection tv? if it is then it may be the bulb but i would recomend just getting a new set because repairing your current one will cost alot and wont last long so a new one is a better option

If you hear a grinding,whirling,spining or buzzing sound, that sounds to me like the COLOR WHEEL,the reason for that is because your color wheel spins at 5,000 rpms(revolution per minute) and something that modifies the balance of the disc can cause different things,Unfortionatelly the only way to check that the color wheel is working properlyis you need to check it out physically
I did some research and I found the color wheel at DM;http://www.discount-merchant.com/Samsung-Replacement-Color-Wheel-HLS-HLT-Series-p/samsungcolor_wheel_bp96-01579a.htm?CLICK=52978
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.
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.
