Try checking some of the tunning and coupling capacitors around the horizontal section as well for some crystalized solder joints in that area.

SOURCE: Magnavox projection TV - Sound cuts off when changing channels.

Yea. Your model FP5210 is much older than one with digital SSB board. Still would think that the mute is being activated; probably by the ucontroller/cpu IC.

My Philips Magnavox 60 in rear projection TV # PTV775-AH01 has no power when you turn it on. How can I fix it?


It sounds like a power supply problem, it could be as simple as an internal fuse (not the fuse in the plug) or something more sinister like a transformer issue which can become expensive, either way i wouldnt recommend repairing yourself unless your confident with electrics and know what to look for

Magnavox rear proj (model# 8p6044 c102) pic is cloudy/green tint


Yes the coolant gets crud buildup in it over time which will cause the color and clarity to get very poor with obects that will glow around certain bright ojects. You can get the Phillips CRT coolant replacement kit from www.tvrepairworld.com which has the CRT coolant for all 3 CRTs and also includes the Cd with instructions on how to do the replacement.

Well, I'm assumig you've already attempted just turning it off and letting it sit for a few hours. I would also recommend unplugging it and letting it sit for a few hours before plugging it back in and turning it back on. These TV's have this problem fairly often, and it's normally a result of a bad flyback transformer, which is a part you need to order from the manufacturer. I would advise having a licensed repairman replace the part, because it is fairly difficult. Even with practice, things can still be broken.
The flyback transformer is the component that generates the large amount of voltage required to drive a CRT. If you decide to replace this component yourself, order service manual #7566 from Philips - it will give you a lot of schematics and tips that are very useful.
