Question about Philips Magnavox 51MP392H Rear Projection Television
I recently replace the ICs for my 51MP392H to remove blue "3-D" like shadows. The replacement worked to solve that issue, but now the blues and whites appear washed out. When trying to adjust the multipoint converge, the symbols look blue in the center of the screen, but green towards the outside. When watching TV or a movie, the whites look okay in the center, but yellow towards the outside edges. All blues look a little "off." Is this just a CRT issue, or could it be something else?
Hey guys here is a great thread on this subject, its were I posted most of my pictures and there is a link to the manual in there. hope this helps,
BTW, IF ANY OF YOU GIVE UP ON YOUR 51MP392H/17 PLEASE LET ME KNOW!!!! I WANT TO BUY YOUR CONVERGENCE BOARD... "I killed mine" email@example.com

Sounds like you have a grayscale problem. Did you use a soldering gun when replacing the parts? Did you turn the TV? Sometimes just turning the set off and letting it cool down will automatically degauss it when you turn it back on. Do you have the service manual? If so let me know where you got it as I'm looking for one. The manual should tell you how to adjust purity and grayscale. If not, mark the screen controls for each tube and turn off two of them to check the purity of each CRT. If there is a purity problem you will need to degauss the set and mark the position of magnets on the neck of each. A white paint pen will do. Adjusting the magnets can be tricky and will affect the convergence so you could end up with a bigger problem. Good luck.
