This set was acquired by a friend who when collecting a few sets for himself, thought of me when he saw this one. Subsequently given as a gift, many thanks Mike.
Initial Power on result.
Powered up flashes at edges of the screen crackle and pop in the speaker as the set repeatedly trips.
An excellent addition on this model from Thorn is the diagnostic ports TSA ( Scanning) & TSB (Power Supply) to see if the expected voltages are present, helps with fault finding. It will help to narrow the fault down as the set can be operated with any of the daughter boards removed. Along with removing the supply rail fuses to isolate the fault/trip condition should be found.

Armed with the service manuals for this model, I’m hoping I have a little less torrid time with this Thorn, than I had with the 8500, 9905 and 9000.
