[TechAssist] Re: RCA model#F19430 (ctc156B) set dead

Junior:

We get a lot of those little RCA/Daewoo sets.  I bet your Flyback is bad. We
have seen bad
regulator IC, dead short, will blow new AC fuse instantly. Seen about 30 or
40 of that
fix. Then of course the other common failure on that chassis is bad flyback,
causing dead set. No blown fuses or anything, just dead. Seen probably 60 or
70 of those.

hi techs.
I have had worked a few of these RCA mod# F19430 sets that were dead.
normally the reg is shorted . But with this one the reg is good , and you
can hear the
power supply start up when you plug it in.when I switch it on all happens is
the degaussing
relay cuts in for a few secs  but nothing else . it has the 5v for the
eeprom and the sys control .
this set carries a GCT841B ic for the signal and deflection and I am not
familiar with this ic.
can any one tell me if there is suppose to be a standby voltage on this ic ,
or Evan the pin out
for this .
