Question about Philips Magnavox 51MP392H Rear Projection Television
If you take the back of the TV off like 4-6 screws star head/shape style, you can clean the lenses and there is a BIG mirror if you stick your head in then turn it around like in the excorsist you will see the mirror (sorry only way I could think of explaining it
I'll attach my general message there is a link to the service manual in it.
NOTE: I did read somthing in the manual about what NOT to clean the lenses with and how to clean them I don't remember so be sure to read it they might have some sore of coating?? just do a word search in the manual.
I found this in my manual however I would look at the link to be sure in your manual:
2c) Using denatured alcohol on a cloth made of 100% cotton or a lens cleaning tissue, gently clean the C element (fisheye) lens, coupler and the CRT faceplate. and allow to fully dry.
Caution: Do not use soap or detergent type substances to clean the coupler and its related assemblies.
I remember as a kid those heaters putting out a lot of residue, so good luck, however I fear your problem may be in your expensive lamps, and these TV's are not that relaible...
Generic informational 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

Suburban Electronics http://www.suburban-elect.com/
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
