Question about Philips Magnavox 51MP392H Rear Projection Television
I HAVE A PHILIPS MAGNAVOX 50" MODEL # 9P5034C103. THE PICTURE IS BLURY, WHEN WATCHING A MOVIE THAT IS WIDE SCREEN THERE ARE WHITE GHOST LIKE AREAS ON THE BLCK PART ON THE SCREEN. WHEN TRYING TO DO THE CONVERGENCE ADJUSTMENT YOU CANT HARDLY SEE ANY DEFINITION ON THE CROSSES TO ADJUST THEM PROPERLY ESPECIALLY THE BLUE. PLEASE HELP! I CANT AFFORD TO REPLACE THE TV RIGHT NOW.
What you're describing is probably contaminated coolant in the crts. Between the outer part of the crt and the lens is a chamber filled with a coolant (ethyl-glycol) which can become contaminated and cause blurred picture. I'd strongly recommend taking this to a shop the procedure for changing these is a bit beyond the layman level.
Remove Crt assembly. Mark the Crt lens position for accurate reasssembly.
Mark the centering ring's postions to make easier realignment and carefully remove lens assembly by removing the four torx screws. Keep Crt assembly vertical so you won't leak the fluid...
Remove the inner lens by carefully prying up on the edge of it.
Dump out the fluid in the sink and wash the face of the Crt and chamber with water to remove all the fungus and crud. Flush the chamber with isopropyl alcohol to kill all the fungus and dry thoroughly.
Reassemble inner lens and outer lens and tighten all four torx screws.
Remove side filler plug and fill chamber with approved new Crt coolant, reinstall and converge.
Repeat this procedure for the other two Crts. It will need this done whether it looks clear or not !! The green and blue Crts in this unit are prone to this failure.
Hope this helps
