Question about RCA P52929 52" Rear Projection Television
After hurricane Rita come through, and power had been returned to normal, the 5a 250v fuse was blown, replaced and blown again. Up until this point I had NO problems with the TV. Since then have looked vigorously for any possible/obvious component damage. Only one componant was visibly damaged (burnt), a 220ohm resistor, this was replaced, another fuse put in, only to blow another fuse. What am I missing? Help greatly apprecciated! RCA 52" Projection TV Model # P52929 Serial # 111651490 Chassis # PTK195S11B Mfg. March 2001 FYI: After Rita, this happened to nearly ALL electronics in my house, some I have repaired, others still troubleshooting.
Was this the 220 ohm in the power supply??? and if the 5 amp blew right away then it probably took out the bridge rectifyer with the power surge that comes alog with hurricane damage to the power lines as I used to live in florida and repaired lots of sets damaged from storms!! After you check the bridge rectifyers I would start looking to find any other shorts. First measure across the ac line with the fuse replaced but not plugedf in . If its shorted check what I mentioned before if its good after you replace the shorted parts you maybe in luck. need more assistance go to sams photo facts download a schematic and we will trouble shoot this together if you post it here so i can look at it. good luck
