Re: Pye television 1956 screen problem
Circuit diagram of the frame timebase. Replace all the marked capacitors. Don't bother to test them, they'll all be leaky.
C85 and C86 are the sawtooth forming capacitors. The cathode bias resistor of V22 is un-bypassed. C116 (180pF) feeds the flyback pulse to the line flywheel discriminator. Possible function is to prevent hooking at the top of the picture.
