I just acquired a Philips 50P8341 rear projection TV for free. It powers up fine, picture has a white/blue ghosting/halo effect around objects. Tried doing some adjustments but can not remove this ghosting/halo effect from the picture. Anybody have any ideas where to look or what is causing this problem? Is there a service manual to be had for this model? I have already found the USER manual but this is of limited use. I am capable of doing any work on this myself, soldering/desoldering, have O-scope and DVM and can read a schematics. First time working on a RP-TV. I have also heard from others about a Fluid change? How do I go about checking this level? by eye? Many thanks.
