Problem solved.
I had the exact same problem with my Magnavox TV. The screen would shrink then expand. After thrity minutes it would correct itself. Then one day it just broke - no sound and no video. I searched these forums but did not find clear instructions on how to fix it. I gave up and called in a repair tech. He fixed my TV in less than 30 minutes.  To help others like me I documented the fix and created a step by quide and repair kit to fix the problem. You can find it here. http://www.magnavoxhelp.com

Hello lagqboy,
It looks like you are having a high voltage problem where one or more of the HV components are failing. The picture starting off small and the growing as the TV heats up is a sign of this (high voltage) problem. The problem experienced when a bright scene occurs is due to poor high voltage regulation. I would suggest that you take this set to a qualified TV repair shop due to the fact that the section I am talking about deals with voltages that can be fatal. 
I hope this helps,
Thank you,
Shuttle83

I have a Philips Magnavox ptv843 and it has a red tint. The picture is really dark, I can hardly see anything in dark seens. I tried to adjust the contrast and brightness but no help. Thanks


These TV's are known for polluted coolant in the picture tubes.The coolant is between the lense and the tube. The factory has a Service Bulletin about this problem and they say to change the coolant in each picture tube. This will make the TV look like it did when it was new.

Screen is getting darker



The most likely cause is the blue and green tubes need to have the cooling fluid changed. After many years the blue and green get clouded with algae. The red tube won't have the problem due to the red spectrum kills the algae before it has time to grow. 

The way to replace the fluid for is to completely remove each CRT from the set, remove the drain plug, drain the fluid out the tube, disassemble the lens, give it a good cleaning; then reassemble; add fluid; and reinstall in set. If you check with the site www.TvRepairKits.com they are working on a kit that includes the fluid and photo instruction guide.

My 60" Philips Magnavox, model 9P6034C103, chassis PTV835


It could be the flyback losing resistace in its windings. What is the chassis number I should have the service manual for it. Phillips/magnavox is hard to cross reference without the actual chassis number.

Unknown AutoLock on my Philips rear projection tv


If you look on the rear of the set and locate the chassis number can probably assist you. But I will need the chassis number for RCA & Phillips/magnavox.
