The set has been sitting in dry conditions for a while now and yesterday I had a chance to try it.
There is a raster and it responds to a signal in the aerial input, sound is working.
But there is nothing much besides flyback lines on the screen, somethinsg not right.
I found some service data from Television magazine but have yet to see a schematic of the signal stages.
Does anybody know of stock faults which could cause the symptom Ive seen. if it was an old hybrid set I'd expect the video output valve.
Maybee this set uses something similar to drive the luminance.
Has anyone got a schematic please?
Kind regards, David.
