everything in that area I checked.

I pulled out a mirror, and I suspected that teh controller IC/CPU, and the
jungle IC has no power.

because, when i jump the relay the deflection circuits kick on, but none of
the front controls work, the power LED IS NOT on. and there is a dark gray
raster. if i pull the plug, it powers off. There is NO SOUND either.


Is the power switch toggling the uP? You'll have to trace the
circuitry to determine this, with no manual.

i think the front ICs dont have power, but I dunno where to look. no
schematic.

.. .
I received this set, its dead with no relay action.

Checked fuse, ok, checked HOT, ok.

I checked volts, it dies off at the relay.

I put the unit on an iso transformer, and jumped the relay. Set fired up,
and powered on.

if i remove teh short, it shuts off. I checked the volts at the relay coil
when pushing power button, nothing.

Any ideas?
