These procedures are from the owners manual, go into menu and then picture quality and then:
The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’
images are precisely aligned, they create the color images you see on the screen.
Over time, the picture can drift out of alignment (this is normal). If your picture
seems fuzzy or has a yellow tint, using Convergence could correct this
misalignment. Only one convergence is needed for all inputs, regardless of the
Note: Make sure the TV has been on for at least 30 minutes (TV needs to
warm up for best results) before starting Auto Converge or Red/Blue
When you select the Convergence feature, a submenu appears with three options:
Auto Converge Automatically aligns the projection lenses to self-correct
color images. You’ll see flashing squares of color dance across the screen
(this is normal).
Note: After performing auto convergence, use the Blue Centering and
Red Centering menus to fine tune convergence in the center of the
screen, if necessary.
Blue Centering Aligns the blue and green images to fine-tune the picture.
Red Centering Aligns the red and green images to fine-tune the picture.
Note: The ability to change channels is disabled when adjusting the
convergence options. The TV must be tuned to a usable signal to
converge the picture.
You need the Phillips DPTV305 - DPTV345 Chassis convergence repair kit which is available at the following link. the kits contain the parts and detailed instructions on how to do the repair.Just click on the phillips repair kits page. http://tvrepairkits.net/
Your tv is crt-based and is out of convergence. In other words,
the settings for keeping the Red, Green and Blue images aligned have
drifted and must be reset. This is common with CRT projectors and
CRT rear projection tvs.
Refer to your owners manual for instructions on re-aligning it.
sounds like the high voltage transformer arc or one of the picture tubes arc causing the convergance ic to go bad you can try to replace the IC heres a site to help: http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm
