Question about Philips 51PP9303H Rear Projection Television
Turns on and holds a pic but then starts to flash from big to small pic. and colors are messed up and cant colers right
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

Hello, below in my post is a link to the Manual library. there are detailed instructions on how to adjust the color. it takes time and some steps are difficult but using two people you should have no problem just print them out and go step by step... also I suggest doing it at night with low lights or off, and let the TV warm up for 20 mins.
Good luck, below is my general post with lots of info
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

Manual Library you should find all you need here:
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
