I have a Philips Magnovox 8P6044 C101 60" rear projection tv that appears dim and slightly blurry. Waht are the suggested fixes and what would be a range of repair costs?

Sounds like a coolant issue with the CRTs. Look into the lens of the green and blue CRTs and you should see what looks like bacteria if the coolant nees replacement. Usually the green and blue get contaminated which dims them and makes the red become dominate and the picture will get dim and out of focus.

sounds like circuit board problem consult a technician

mine is doing the same thing and it is the same tv same year

The CRT fluid is cloudy and should be replaced. Goto www.TvRepairKits.com. They have a kit to do it yourself.

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to...look white, look dull, look red/orange, etc. You may even see halos around images. 

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

I have 50" philips magnavox big screen. I recently started to have a problem with the edges of my tv. They became blurry. the center of the tv is clear and the edges are blurry. what should I do to fix this problem.

I would suggest that you check the HV output first this could be a sign of a decrease in HV and or a focus problem. Check the trippler, The IHVT, and the focus block (this is usually attached to the IHVT). Then I would check the actual CRTs (items to check: filament voltage, HV at the HV anodes, and screen grids of the CRTs). If you do not have a background in electronics, I would suggest that you have a qualified TV technician examine your TV set.

I hope this helps

Thank you,

this seems to be convergence problem in your tv .............

coolant fluid on picture tube may be contaminated replace it an setbe ok (this is a technician job)

If decide to do yourself, ya only have to do the green and blue ones, the red light spectrum won't allow fungal growth. Pull whole CRT assembly out to prevent spilled/leaking glycol from onto lower main boards
