RCA CTC177BP2 part CR4112
RCA TV chassis CTC177BP2 part CR4112
My RCA TV went dead, and after discovering the "RCA/GE TV (CTC175-187+) Solder connection and EEPROM Problems" page, I went to work on the chassis. I did the tuner regrounding, and checked the other parts mentioned, but the only part I found defective was a diode that had overheated and gone bad. That diode is CR4112 (not mentioned in the above). Problem is that the parts layout diagram on the TV doesn't list CR4112 or the parts around it; they are simply missing. And I can't figure out what type of diode it is; the only markings on it are 95J5c, which doesn't lead me anywhere. The diode has 2 ferrite beads on the leads, and is flanked by 2 ceramic caps. It looks similar to the AC rectifiers, but a little smaller. If someone knows what this part is, or what a good substitute would be, I'd really appreciate it. Thanks in advance, Tom Harrison |

Hi!
CR4112 is a nte 552. I find that the regulator is shorted and also sometimes the horoszontal output transistor. Vince wrote in message oups.com...
