My phillips magnavox big screen tv model number 55p8288 doesnt have any sound when i turn it on


Check the audio setting to make sure the internal speakers aren't turned off. Check to see if it's set to use external speakers. If it is setup to run sound through an av receiver check all connections, make sure the receiver is on the correct input setting, and speaker wires.

Double vision on tv with purple and green colors


Hello,

This television set, as well as most rear-projections, is prone to convergence driver problems. There are two large chips (STK392-110's) in the TV that need to be replaced, as well as some resistors that are likely damaged as well. Any competent TV repair shops should be able to repair this TV for 200-300 dollars. It is important to note that if the back of the TV is taken off without the proper prep., the Digital input (DVI) will be disabled permanently.

Hope this helps you...

A 10 year old Rear Projection tv is usually at the end of its life. No such thing as "fluid". Best advice, get a new TV.

General post....

Actually I have this TV and 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

Where I got all my parts that worked:
Suburban Electronics http://www.suburban-elect.com/

Manual Library you should find all you need here:
http://www.techlore.com/group/2/list_downloads



What you need:
(2) STK392-120 OR STK392-150 IC chips
(12) 6.8 Ohm Metal Film resistors
set of star screw drivers
15 watt pencil solder pencil, DO NOT use a high watt iron you will fry the surface mounted item.
good leaded solder, and flux


BTW if you don’t plan on trying this and are going to throw out the TV, I still need a IC convergence board for a 51MP392H/17 TV I'm fixing, I'm willing to pay S/H and buy your IC board that’s not been tampered with. Edwinkraus@hotmail.com

TV- rear projection


If you try to adjust this you will make more work for yourself. The problem is convergence amps go bad and anything you adjust now has to be readjusted when problem is fixed. Also, convergence problems are a very common problem in all brands of projection televisions, not just magnavox, because the amps run pretty hot holding the colors in aligment. It's unfortunate you had bad luck with this set but we are also now seeing LCD, DLP and PLASMA sets that barely make it through the first year. More and more brands only carry a 90 day warranty now, so they know the life span is decreasing. To repair your set you will need soldering/desoldering equip. and test equip. or you could pay someone with experience 175.00-375.00 to solve your problem for you. That's why we're here. Lots of luck, Russmann.

Philips rear projection color and pic problems


 
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 or kits 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 I documented the fix and created a repair kit and step by step quide on how to fix the problem. You can find it here. http://www.magnavoxhelp.com
