A neighbor moving out left me this non-functional Hitachi 35UX85B, now
to get it to work!!! Upon Power-up the relay clicks, but there is no
audio, video (raster), or visible LED's on the front. This is
accompanied by an intermittent chirping sound (~1 - 2 sec. interval).
The "Chirp" is coming from the Power Block in the vicinity of T-902 and
is audible in a quiet room (sounds like there's an agitated mouse in
there....but there isn't). All fuses (2) check out fine. Upon
Power-down the "Chirping" will persist another 8 - 10 secs. after the
relay shuts off power. Boards look good as well, no obvious fried
components/connections, shorts or dry joints.

I downloaded the service manual and it has all the schematics and
specs. but does not give much help in the troubleshooting flowcharts.
Before I cause too much havoc with my Fluke and soldering iron, does
anyone have a good idea of what are the likely suspects?

Mucho thanks for any help.
