I am unable to adjust the red color in the convergence adjustment on my IQC50H94W 2000 Zenith 50". From everything I read I believe I need to replace my Convergence IC Chips, however I am not 100%...


Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

My projection tv lost its blue tint


Hi

Thanks for using FixYa. Usually this happens when the Light Engine has gone bad, and I should say this is a common issue with Projection TVs. There are three tubes/mini LCDs inside your TV- green/yellow, blue and red. When the set heats up over time of usage the screens tend to break resulting in leaking color everywhere. The cost to get this fixed by a professional should be around $300 depending on the parts that needs to be replaced. Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks
Rylee

I have a Zenith Projection 50" TV IQC50H94W that has a blue arc


You need to replace your STK392-150 I.C.'s, Also, check all of the large nearby resistors, make sure none are burned, and remember, you have to check the resistance out of circuit with a meter.

once the resistors are checked, and the convergence I.C.'s replaced, you should be able to converge the picture through the user menu.

Tube set zenith tv


This is very typical of a Zenith set.Your picture tube will have to be replaced.One of your 3 primary colors (red,green,&blue) have turned off leaving you with the color of the dominant color.I would heave it.

The convergence IC's should be the first suspect in any convergence issue. Hopefully you can place the magnets back where they were or you will have that alignment to deal with first.
