i recently was given a panasonic with a bad set of ic chips by an elderly friend (eugene). he was going to haul it to the dump but opted to let me have it when i told him i thought i might be able to do the job though i couldn't say for sure. anyway i got home and fixed. it was intended to replace the tv he's using now. it's a crt rear projection also. i thought since this one went so well that i make an attempt to fix the off color semi fuzzy image on his tv. i have tried some adjusting in both the settings menu and dials in the front (focus and screen both). only done this because i was fairly certain someone had monkeyed with the front before. after tinkering, i believe there is an issue a signal going to the green light gun. it doesn't do brown or whites very well. you can also make out some text in the convergence adjustment with the red turn up to though it's just black and what i would believe should be green. i did mange to get it better but it was only done by adjusting a to the point it had a green have over everything. (very noticeable with the blacks but still no green text anywhere). i confirmed this when i removed the back while it was playing and the red and blue light guns had an image but the green was not putting an image out. it was just brightly lit. i have limited knowledge of how these work exactly but it seems to me the green should have an image to. if anyone has any experience with a hitachi 50dx01b 50" or has a general idea of what i should look at or check, it would be appreciated by both eugene and myself. i did look the caps over, all the connections and for open resistors already. maybe the board on the light gun, idk:dontknow:?
