Poor picture quality. Picture also tends to curve

Since the boards and most parts are not available for this model from Philips the only hope is to have a shop take a look, voltages and other checks MAY reveal what is wrong but I would not spend a ton of money on this set, was prone to a lot of problems and middle of the road as far as picture quality.

model is older philips set----try to describe the problem a little more

Are you getting some kind of high pitched squeel from set when you try to turn it on?

The more you tell me the more I can help.

Fluid has leaked out of one or more of your picture tubes ( 3 of them ) I suggest you call a service company asap because that fluid can destroy boards in a hurry.

This is a common problem with older Philip Magnavox projection sets. Over time one of the IC chips on the main power board begins to fail. You can find replacment chips and repair instructions on www.magnavoxhelp.com.
