[TechAssist] Re: Toshiba 20A42, Dead with two shorted rectifiers

Good point Jeff.
May be an idea to post both.
Some Model numbers have not matched up with Canadian (Toshiba), compared
to US.

This set seems to have taken a lightning hit, two rectifiers and the
fuse were gone.

Now it won't come up all the way, it seems that high voltage might be
starting, barely, but then
everything is quiet. B+ voltage doesn't seem right, it's sitting at 165
when the set is off, when the set
is turned on, it takes on different random values, 105 one time, 115 the
next, 110 the next time. The B+
adjust pot has no affect. Other PS secondary voltages seem to be
present, the power led is on when the set
is on. I have a schematic, but some of the voltages listed there seem
wrong, as though they were measured
from the wrong reference ground.

The set is not worth doing much to, but if someone has any ideas that
would be appreciated. Thanks
