Hi,
my Goldstar OS-7020 refused to show something on the screen.
As far as I can tell, without a schematic, the High voltage is missing.
The heater voltage is present as are various power supply voltages (+/- 12V
for the opamps and +5V for others.
A service manual or schematic could be very andy to trouble shoot the scope.
Anybody who can point me to a link or make a copy?
Many thanks in advance.
Cheers,
Marco
