Mitsubishi Diamond Series T.V.

the crt cap have dry solder, solder it that will work

Televisions covered: all Projection with yellow picture, but not Projection TVs with a yellowish tint surrounding objects in a nearly normal picture.

Yellow = red + green
normal picture = red + blue + green (RGB). See illustration.



Fig. 1 Additive color mixing in an RGB monitor, or RGB Projection TV.

The circuitry powering your blue output, or the blue light engine itself is starting to fail.

Operating Theory:

The lamp module shines a bright light into the optical unit; there are a series of lens and baffles, and at the top of the light engine, a lens puts the picture into a mirror which is reflected onto the screen; All video and color is processed thru the light engine. Blue most commonly fails first, leaving a yellow picture.

This tv have a problems known as a convergence.This problems the tv convergence board,must have the 2 STK convergence ICS some or all it resistors be replaced to solved the convergence problems.These problems are 3D pictures,colors out alignments,colors have shadows,pictures of colors mesh it all together.The shop will cost u $300-350 for parts and labors.

SOUNDS like you have bad filtor capacitors in 9v and 5v circuits. J.D.W.

Ur CRT coolant require changing.Tries websites Tv repair World.com,MCMElectronics.com to buy the coolant for the replacement.

POWER SUPPLY NOISE FROM LEAKY CAPS

Please chech degausing coil around crt from inside

z sustain board going bad

The convergence is going bad

intermittent convergence fail. suggest re-soldering the 2 convergence output ICs on the middle power board. they are the 2 large devices located on the largest heat-sink on the middle board(looking at from back) once you re-solder them as long as the aren't faulty internally you should be all set.
