hi guys, i'm sure this has been covered somewhere before but i have a couple
of big screen 50" Mitsub. TVs with bad colors and convergence installed in
some arcade games! i know how to adj a normal CRT tube convergence with
rings but no idea on projection. i heard this is a bitch to do, is it?
is there a capkit/repair that you can do with these? is there a website to
follow directions on this procedure?

thanks and sorry for the ignorance,
Kelly


That depends... It is normal for a rear projection TV or monitor to
slowly drift slightly out of convergence as the CRTs age. If any sudden
drastic change has happened the there has been a component failure on
the convergence board. Usually it's the large ICs and maybe some caps
and low wattage resistors as well.
If the TV has just slightly drifted, there should be a large amount of
controls on the convergence board which can be adjusted, or it may be
done through the menu, depending on the model.
If it's done by controls, most manufacturers attach a long extension
cable to the convergence control board so you can stand far back from
the screen while adjusting all the controls.
