EKCOVISION T221
There is a good raster. E.H.T. voltage is
present but there is no picture or sound. At first
it was only ITV I could not get, but now I can only get BBC -1 now and again with a broken -up picture. I have changed PCF80 and PCC84 and
cleaned the tuner contacts but this has made no improvement. -E. Bairstow (Wakefield, Yorkshire). The fault is in the tuner unit. Check the h.t.
to pin 1 of the PCF80. If low, check the 15k12
feed resistor and other tuner components. Check
oscillator tuning.
