PYE HYBRID COLOUR CHASSIS
On monochrome, the picture is much lighter over the last
third of the screen, with a magenta tinge. The first twothirds of the picture have a brownish tinge. The colours,
appear to be normal on colour reception, though the right-I hand side of the screen is noticeably lighter.
Remove the CDA panel and clean the print at the sides
and the chassis runners which earth the panel. If this fails to
clear the problem, check the blanking components (VT28
and D53) in the cathode circuit of the PL802 luminance
output pentode, and if necessary the electrolytic decouplers
C367 and C371 (both 4µF) in the colour -difference output
