I had the exact same problem. The screen would shrink then expand. After thrity minutes it would correct itself. Then one day it just broke - no sound and no video.  You can find a repair kit here . Hope this helps.

Re: Philips 9p5034

It is probably something as simple as a bad electrolytic capacitor in the vertical output circuit. if you are handy with a soldering iron, you can change it yourself for less that $10. If not, check with your local repair shop for an estimate and make the decision on repair or replace based upon the cost of each. Panasonics are usually a very reliable set and if it is good shape otherwise, it is probably worth getting repaired. Incidentally, continuing to operate the set in this condition will blow the vertical IC and add to your expenses.

Tv picture shrinks

This is a common problem on certain models of Philips Magnavox TV sets. The most common symptom is the screen will shrink and expand over and over. After the TV heats up for a while the video will work like normal. After a few weeks or months your TV will eventually stop working and not have video.

I never had this problem on this particular unit.....But it is in the large signal board, the one with the flyback, that is troubled. A bad cap [look for high voltage [160v or 250v with 1 to 4.7MF] Check for loose grounds around heatsinks or power resistors or a leaky horizontal transistor or regulator. These are good places to start. And don't over look diodes! These are my ideas!!!!
