SYMPTOM Too much red or colour bleeding in the OSD and teletext displays.
CAUSE
IC801.
This can be checked by examining the R, G, and B outputs on IC801 - pins 17, 18,
and 19 respectively.  If one is higher than the others in the OSD mode, then the IC is
probably faulty.
Note that the OSD and teletext signals are generated by the microprocessor (IC1001)
and  fed  into  IC801  for  switching  between  OSD/RGB  input  and  the  decoded  video
signal.
ACTION
Replace IC801 using the part number given below.
REF NO
