PHILIPS G8 CHASSIS
There’s an intermittent convergence fault on this set. The
right-hand side of the screen, particularly the lower part,
goes out of red/green convergence. The fault can be present
at switch on, and remain for the whole period of viewing
and for several days afterwards. At other times the picture
will be perfect for several days.
This is a fairly common problem on receivers with the
chassis -mounted convergence unit. The fault is usually due
to the RIG parabola control R1934 becoming intermittent
or dry -jointed, or a similar defect in the 2.7Q resistor
R1919. Gentle probing should reveal the fault, and
replacement is simple. Repeated failure of these components
can occur if the h.t. is excessive, so this should be checked
and if necessary reset.
