UPDATE: RCA TV (32" pic) F32676SB, ch CTC197CD
Hi,
I replaced the FBT even though all out of circuit tests on it revealed no defects. With a new FBT installed, the TV stays on. The HV is over 30KV (with a picture showing) and B+ is 141.5V (TV on). A label on the chassis (for this 32" picture tube type), says, "HV 29.5KV / 34.2KV". I assume this is a range of minimum to maximum? Please let me know if I am wrong. Thanks in advance, Brad On Tue, 18 Jul 2006 20:55:13 GMT, (Brad) wrote: Hi, I have a RCA (32" picture) TV model F32676SB, ch CTC197CD (mfg. 12/96) in my shop that shuts off right after turn on. I can hear HV at turn on. The regulated B+ is 151V in standby. Using a 250 ohm dummy load, the B+ voltage drops to 141.5V. I do not have a SM for this set. Is the standby voltage too high? Thanks in advance, Brad Before you type your password, credit card number, etc., be sure there is no active keystroke logger (spyware) in your PC. |
