I am repairing this Teac TV ctm687 which has a grainy picture on all
channels; even when using the vcr (however the tapes play a normal
picture.
Hence I suspect the tuner (oscar 2900kkc) for which I measure 7.87
volts at the AGC pin which goes to i/c TDA8305A pin 5 which according
to TV schematics should only have 3.9 volts.
My B+ at the tuner is 12.11 and I wonder if this is the correct supply
voltage to the tuner.
Thanks in advance.
