I would like to know ow yo fine tune my Yellow and Green colors on my Mitsubishi HD 1080 Series


If this is an auto convergence you may be in for a bit more of a project than you want to be into. If there are separate color guns then you can adjust them individually with a screwdriver from inside

Image is bright but there is a slight issue - on the left hand side a purple line displays vertically. Anybody knows why is this fault appeared and how could it be solved.


There is three LCD in the projector red, green and blue. If green LCD make any fault mean line or dot or dots then screen show these line or dot in purple color:
If line is very straight and sharp edges then green LCD is faulty and need to be replaced.
If line is not straight and faded edges then some thing in LCD block so your projector need service

My video yellow plug works fine, showing correct video colors yet, the red blue green connection is only showing picture in a pale green


Yellow is composite input if RGB is not working it's probably a cable/output problem try with a different device first.

You need to replace both convergence ICs STK392-120 they are an easy repair you will also need (4) 6.8ohm Convergence resistors. You can get replacement ICs and the resistors at the following link and they will provide free installation instructions and free on line tech support so you will be able to do the repair yourself and save about 400.00 for a 45 minute repair. heres the link.

Colour problems with projector


In short If the reds show as red, The greens show as green & Blue shows as blue. I would say thats as good as it can project. It's hard to judge color without seeing it for ones self but usually DLP projectors that use a colorwheel do not have perfect color.

Red & Green seem "off centered"


Your set uses the 195 series chassis, which has separate components for each of the 6 convergence channels and a separate power supply for the convergence circuits. If all 3 colors have drastically shifted, especially around the edges, then chances are your convergence power supply has stopped working. This is usually caused by the failure of the STK730-010 switching IC. If one of the colors has dramatically shifted by itself then something has stopped working on the convergence board. Sometimes I see CRT coolant leaking onto the convergence board as the cause. In either case this is something that should be repaired and realigned by someone experienced with RCA projection TV convergence circuits.
