I REPLACED THE TWO 2200UF CAPS ON THE POWER SUPPLY MAIN BOARD . BOTH THE BAD CAPS WERE BULGING AT THE TOP. I COULDN'T FIND DIRECT REPLACEMENTS SO I USE ONE 4700UF AT A HIGHER VOLTAGE RATING FROM RADIO SHACK AND FIT IT IN OVER THE BOARD. JUST MAKE SURE YOU INSULATE THE LONG LEADS.

Have a look at this instructable:
It describes fixing a W5001C with the problem of a blank screen but still having audio.

They have a parts kit for a common power supply failure for several Dell HDTV including the W5001C Look for bulging capacitors on all circuit boards and replace with the same UF (microfarad). However it is better to replace them with a higher voltage and tempature rating if you can find ones that fit on the board and chassis. Use an ESR meter to find the bad caps that are not bulging at the top. You do not need to unsolder the caps to test them with the meter. Electrolytic Capacitors are the most common failure in all modern consumer electronics and they are cheap to replace. It is because they are organic and dry out over time. Faster in hot environments like sandwiched between 2 large heat-sinks in the power supply section of the circuit board of a large screen plasma tube as in this TV.
