Got a dead one, seems the SMPS is dead, no output on any rail. There's good rectified DC present at the bridge on the mains side, but it the chip (ir2153) doesn't have a steady 10v supply on pin 1 - maybe that's enough for someone to give me a pointer [emoji28]

Or if anyone has a service manual and can send the relevant sections, I'd appreciate it.

Thanks in advance [emoji120]
