Hello all, this is my first post. I have a Sony KP-57HW40, RA-6 chassis
that has a shutdown problem. After the set runs for approx. 15 minutes,
there is arcing under one of the connectors on the D board and then the
set shuts down with a HV error. I unplugged the socket from the CRT's so
that only one was on at a time. The problem only occurs when the red CRT
is connected. I would suspect the CRT is arcing internally and feeding
back to the connector. Is there a possibility it is not the CRT. The
arcing appears to be between pins labeled G2 and DFT. Is there any
chance a bumpy ride in a truck could have caused internal shorting of
the CRT?


It's probably the CRT, but if you can make the cables reach, try
plugging the green, or blue CRT socket into the red CRT.
