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

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
