Right found a working one of these now
Need to replace as the guy has had a go at repair and somewhat ruined the board .

Whilst trying to change transistors on IC201 he has damaged pads and also burnt off pads on the PSU where IC201 goes on .

Voltages are way out 30v showing 40+,
12 showing 17+
Ground showing 8v??

To start with it was in standby and with resolder and cleaning up the above is where its at so will fiddle with it some more till the new board turns up but think it may be past saving
