Hi,
Do a "power on reset" test. Remove the PIP module. It's the first =
one
beside the tuner. On connector J12101, the farthest one looking into the
board, jump pins 3, 7, & 9 together. Also jump pins 5, 6, & 8 together. =
Test
unit for normal operation. If this test is a success, from the Thomson
website do the modifications to repair the power on reset circuit. =
Someone
else will have to send you that service bulletins my send is broken.
HTH,
Lindsey

We have a RCA CTC203CH3 which goes
into shutdown after one second..The base waveform of
the output transistor looks ok and the high voltage
comes up to 23 kv for a second..Output transistor
and scanning diode checks ok..B plus is 134 volts
on flyback..Any help with this unit would be greatly
appreciated.
