The above model TV started to flicker, losing red then reappearing.
I don't think its the tube (guaranteed anyway), bt somewhere in the

CAn someone point me at a website with the schematics?

I'm afraid my tv/analogue skills are rather weak as I'm a VHDL/FPGA

Any help welcome.
(Also, my old 'scope burnt out, so diagnostics are difficult as well!).

TIA, Niv

Never hear of a Protron losing reds and reappearing, now do we?
