Question about JVC Hd56fn97 56-inch 1080p Hdila Rear Projection Tv
A few months before Bulb fused and replaced then no red color coming. More purple and Greenish. Last week bought a new tv and now digging more on JVC TV. visually i cant see any problem in parts. disconnecting each ribbon cable to light engine Blue Green & Red individually and found no color difference in RED. Then i removed the Control PCB-LCA90635 and removed the color engine(a full block with lens and mirrors) and found one clear plastic glass burned and melted with over heat, took it that glass and fix everything back but still the same problem no red. Is this the color engine problem or control pcb ?
Does menu have any red? Yes = digital video bad; No is light engine bad.

SOURCE: I have a JVC HD-ILA
I only have bad news for you. This tv uses an engine assembly. It is impossible to replace the color wheel only. The entire assembly is quite expensive and wouldn't be worth replacing for a tv of that age. (By expensive, I mean roughly $400-$600, before labor). To replace the assembly the tv is basically broken completely down for this repair too and thus very expensive for labor as well.
Sorry for the bad news, but with no warranty you seem to be out of options. Some people choose to just live with the color issues, while saving for a new tv.
Thank you and have a nice day! :)
