Hello all, this is my first post. I have a Sony KP-57HW40, RA-6 chassi
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 th
set shuts down with a HV error. I unplugged the socket from the CRT's s
that only one was on at a time. The problem only occurs when the red CR
is connected. I would suspect the CRT is arcing internally and feedin
back to the connector. Is there a possibility it is not the CRT. Th
arcing appears to be between pins labeled G2 and DFT. Is there an
chance a bumpy ride in a truck could have caused internal shorting o
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.

Sometimes tapping on the neck of the crt can dilodge a contaminent
causing arcing (rapidly all around the neck of the tube,but not to
hard)
