Hi all
This B & O CRT TV is firing up , HT rises to 153V , with just a rustle of EHT , then shuts down.
If the on board button is held ,PSU pulses.
Removed line O/P transistor & used a 100W bulb as a dummy load , but still pulsing with button held .
Anyone know this set well enough to help distinguish whether i'm looking at a PSU issue or not ?
Depending on design PSU might be shutting down due to not receiving feedback .
Schematic may help
