I have the older 65 in rear pro.one day to the next the lines color lines drop off on the bottom corners. I can fix the red and blue line but not the green line
You need new convergenc chips, this is the most common failure in all rear projection crt tv's. the part numer is either stk 392-570, or stk 393-110, the tv needs to be taken apart and the chips have to be soldered in, a qualified tv repairman could do it, but a consumer could not, and would probably damage the set trying.
