I have read the first 10 posts, and I have experience with convergence on this set.
I have a Mitsubishi WT42315. The SDK's failed 20 months ago. I replaced them and a PICO fuse. The set worked till now.
RED will not adjust LEFT or RIGHT. RED adjust UP and DOWN OK.
The RED image is...
i replaced the chips and one 2.2 resistor everything lines up and moves fine
now i have to adjust the blue every couple hours and red every day and also noticed bowing on sides and small tilt counterclockwise..
i more concerned about the convergence needing attention so often?
should i try...
I have a Mitsubishi WS-55807, about 7 years old. A problem just delevloped when you first turn it on the red convergence is off. Basically about 1" lower than it should be (double text, bad pic). After anywhere from 5-30 seconds it just fixes itself. Been doing it for about a week now.
