Hi,
Sorry for the length of this.
Here's what I have. This is a service call job on a WS-55311 (Chassis
#V20C).
It was throwing an error code 22 (Short protect). I measured a dead
short on the -24V line, which feeds the convergence output.
When I removed the Heat sink from the convergence outputs, I found that
too much heat sink compound had been applied to the chips, and had
seeped down onto the board. This was the cause of my short.
I replaced the convergence IC's, and now I'm getting a code 23
(Horizontal Deflection Failure). The 110V supply is OK. I assume that I
have deflection, since I'm reading HV drive to the power board.
I double checked that I had replugged everything.
Has anyone had any code 23 problems with these?
Any ideas will be appreciated.
Thanks,
