Question about Hitachi UltraVision CineForm 55VG825 55" HDTV

Open Question

Our 2003 65 inch Hitachi Ultravision projection TV only blue/yell

Recently our big projection TV only started showing programs in blue, yellow and grey's. seems to be missing reds and other colors. when we do the magic focus and other menu troubleshooting we can see the TV showing red but the picture doesn't. does this mean our TV is done or is it something that can be fixed. i was thinking it meant a bulb was out but maybe it is an electronic thing? what can we do to diagnose the problem and decide whether it is worth having it fixed?

it sounds like your blue convergence ic is getting weak you need to replace the ic's STK392-110 and you should replace both because when 1 is bad the other will go real soon. They are inexspensive at the sight I posted and you will also get free tech online support if you purchase them there.

You have a defect in the convergence circuit. Both chips will need replaced and possibly a resistor or two. Chip part numbers are STK392-110. Typical repair runs around $350
