The trouble with this set is a narrow vertical orange strip on
the left-hand side of the screen. There seems to be some
ghosting associated with this.
This symptom usually arises when there is a fault in the
application of flyback blanking to the decoder board. Check
the connection from F5 on the timebase panel to D9 on the
decoder panel for continuity. Then if necessary check the
flyback blanking transistors T4488 and T4524 on the
timebase board, and for breaks in the print, including the
edge plugs, on both boards. On the earlier separate decoder
board there could be a faulty component in the blanking circuit, for example C7213 (1µF). If the combined signals
board is used, check C3216 (1µF), D3218 and the
TBA560C chrominance/luminance processing i.c.
