First thing i would look at is it is probabily dust on the lences and miror, you need to take the screws out all the way arount the screen from the back, then lean the screen out tward you from the front, do this while the tv is on, you will be able to see the dust alot better, take a soft cloth and glass cleaner and clean little miror, and lences

Problem with the Philips Magnavox 9P6034C 60 in. Rear Projection Television, had TV for 16 years. Picture gradually got darker and less clairity


the projection tubes do wear out over time and there is no fix but to replace them. you might first check to make sure the lenses and mirror are clean, do not use compressed air to clean as you may force dust between the lenses. if the picture is darker at the edges or a different hue then the coolant is likely contaminated and needs changed

Hello I have a 2001 hd phillips 62 inch widescreen and my tv seems 2 be getting slightly darker ,now somebody told me its a light bulb starting to go out is that the case and how much is the bulb


In 2001 most of the sets that are rear projection do not use a bulb--if just slightly darker--you may just need to clean lens----easy to do.

Let me know model number and I will advise you.

Picture shrinks to only show top half


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. You can get complete parts and instructions from www.TvRepairKits.com

Darker picture


Clean the lenes inside of the TV and the mirror and screen (a little dust build up on these three things adds up quick!) also if you smoke that can build up too! these tvs have too be cleaned inside

60" Rear Projection TV


sounds like a convergence chip problem...

here is my general post for the 51 inch you'll have to look at the link for the manual and check to see if you have the STK392-120 chips or somthing bigger in the 60"


51MP392H/17
you need 2 Convergence IC's STK392-120's (120's and 150's will work) of course order 2 of the same type I'm using replacement 150's they allow for a little higher heat and were cheaper ALSO you need to replace the 12 resistors with 6.8 ohm metal film resistors, make sure they are metal film! don’t skimp out here I did and then they blew and fried my IC's and I had to replace everything again!

Great reference link that I posted
pictures on, check out page 3
