I have a WD52525 that died several weeks ago (solid red light -- changed lamp -- still solid red)
Using these forums, I disassembled the TV and found 5 bulging/leaking caps spread through several boards.
Replaced the obiously damaged cap and few other suspect caps (Basically all the 1000mF 10V caps)
Reassembled the V26 chassis and reconnected all wire. I did not reassemble the back of the cabinent (But I did connect the FN2 to the fan and put some tape over the filter door cover switch) because I wanted to see if the TV worked before putting it all back together.
After starting the TV it went through normal startup and after 1 min the power lamp turned solid green. BUT no picture at all not even the blue screen. I tried pressing the device and menu button to see if they would display, no joy.
I would appreciate any help

I know the response is now quite late but for those with similar problem, here is my recomendation.
If you can see your lamp glow thru the vent on the back side, then you need to work on your DM board. If light is dead, you either got a philips china lamp or your ballast is gone. If you have a Philips lamp try listening at the right side of the TV, if you hear arcing sound then your ballast works but cannot handle the current required to start the lamp. Clean your ballast board and conformal coat it with rtv or polyurethane clear coat esp the high voltage output side. This will reduce current leakage at the board and ensure that the arcing happens in the lamp.
