There is no on/off switch on that power supply so it must run all the time
but at about one-third power when the set is off. At turn on, the power
comes up to normal. It is unlikely the chip is bad in this case. More
likely a turn-on problem or a shorted load on the power supply. There was a
bulletin for "slow to turn on" but I lost that after a recent computer
crash. Maybe someone else has that. John.

> All but one secondary supply voltage is low. 140v B+ = 55v. One 12v supply
is normal. Have checked all the supply lines for shorts or defective
components. Have isolated each line. Nothing makes any difference. Have not
changed switching I/C SFR-F6656. Not sure that the I/C is bad. Seems to be
working. Wondering if it can work and still be bad? Thought before I replace
it, maybe someone had some experience with this
