The color is messed up. the color is all different colors like red,green and blue.

Your convergence is out of whack.

This can be caused by a failed convergence IC - or can be adjusted using the Convergence settings in the main menu.

White colors schemes seem off white color or brownish color and blue has green tint or baby blue color. .

Check the coolant in all three crt's as chances are it is contaminated (should be crystal clear). If brown (beer color), replace coolant in all three crt's and perform convergence adjust. Picture should be like new!!!

Good Luck!!!

Good Day,

This is a common problem with this TV, but there is an upgrade to correct the CONVERVGENCE circuit problem.
If you want to repair this concern yourself: Contact: B&D ENTERPRISES,
1-800-458-6053, and ask for KIT10 for your Hitachi TV.
If you want some else to do the repair for you call an Authorized Service Center.
Good Luck, big IRISH.

3 year old Mitsubish 52" DLP mdl.WD-52627 TV displays all "Red" colors as Brown-Grey in color. Going to the color level menu and maxing out the Red color bar does no good. Also intensifying...

Found out I have extended warranty and I am awaiting service company to respond in order to conduct service to find the problem.

Thank You

I discovered that the red input from my DISH receiver had come loose. I plugged it in and all is well.

Certainly glad I didn't call a technician out!

Course and fine Convergence adjustments

You don't need to raplace all the resisters! Only the bad ones. Remove one lead of each fusible resister out in front of the STK's & check for the ohmage by their color band. You will find the bad one or two resisters causing your problem.
