Question about RCA HD52W59 HDTV Projection Television
Colors are way off and the pictue is bowed. The is no "auto convergence" on the menu at all. Tha seems wierd since the manual shows one. Is there a fuse or something that can be checked inside this unit? Any assistance would be helpfull.
There is a special fuse on the power deflection board. when blown this causes the processor to think it a crt tv. The fuse calle fl231 is a small brown rectangular fuse in the middle of 3 just like it next to the flyback transformer the big black thing with the large red wire comeing out. ussally it blows because the solder connections on the flyback. WARNING high voltages are generated by flyback. be careful please

Replace FL231, middle fuse (Check all 3 fuses). Check solder connections on Flyback, lead free solder is is very brittle and can't take the heat generated by the flyback transformer and cracks. This increases the overall resistance of the circuit and causes the fuse to eventually blow. Resolder all of the flyback connections with leaded solder, remove as much of the lead free solder as possible with a solder ****** or solder braid before applying lead solder. This will improve the ovall quality of the solder connections as old solder is just that "old solder" also the lead free and leaded solders do not mix well and will weaken the solder joint.

Tin foil works great. Just rig it up by jumping the fuses with foil. Should work like a charm. That's the redneck repairman way to do it.
