Phillips Magnavox model # PTV835 Problem

I have a Phillips Magnavox model # PTV835 and something has gone wrong with the picture. The color seems to be..strange. I go through all the color/tint/brightness settings but no matter what I do it almost looks dull, or too red in some places. You really cant distinguish the colors very well anymore its not like watching a black and white tv but the colors arent sharp anymore. Any ideas?
Thank you!!!!

Phillips Magnavox model # PTV835 Problem

I recently received a 56" Magnavox PTV835 ... Model 9P5034C102 manufactured 1-2000... Chassis # 29116256. The color alignment is way off. When you go into the screen to set the colors.. the pluses are way off. You fix one color & another goes out of align. For ex: when you fix the blue.. the red goes out of align... when you fix the red.. the blue messes up again. Can someone give me an idea as to what this problem might be before I spend a fortune hauling it in to a repair shop?

The ultimate test for color is to turn the color off. If the set is not black and white then you can see the problem. eg too red or too green.

I have a 65" PTV840, and athough I can determine the red and green shades and make some adjustments, it still lacks blue. The clearity is altered due to being so dark now.

Magnavox PTV 835 audio problem


Can anyone provide me with a schematic for this model. I have no audio to the internal spkrs. I know of some problems with the ssb. I replaced it after checking the obvious(spkrs, solder joints, connections, etc)with no results. I am in need of a schematic to do a thorough check of the audio circuit.

My ptv835 has a washed out look to it. It's like the brightness is maxed out even if I adjust it all the way down (or up). It just doesn't make a big difference.

I found where some Magnavox CRTs had a capacitor which was under spec and would do something similar. If I knew of such I would not have a problem replacing it (I know about flyback transformers, etc. and have worked on CRTs before).

Sooo, if you manage to find a schematic - please do post about it here.
