> Hi Guys, this  Sony has a shorted Q801 (2SC2555), I only have a partial
> schematic but I can`t find anything else shorted other than this
> transistor, Q811 is good, D802 is good, no shorts on 115v line, this
> is the chassis that has the "N" board on top of the "D" board so it`s
> impossible to run the set once the N board is removed unless you of
> course have the "cable extenders" that Sony will sell to you for a small
> fortune. I can`t seem to get the members area to accept my username
> and password so I can`t check those files, seems strange just this
> transistor would short, anybody run into this before? tia, Larry E
