Hallo again Rick.I have check the voltage for R62 to IC 1 Pin8 min 0,62V and max 7,07V.I have also check the voltage for R62 to D37 min 0,83V max 3,91V.



Jan

The base Voltage for Q44 is at min 0,63V at max 0,72V.So the voltage is to high for base at min I have 0,63 it sholud be 0,2 its that correct.


Jan

D37 D69 is intact

Sorry didn't you mean R62 instead of R63

I have also check C189 it seem to be intact.

I have the voltage for R232 to Q44 is min 0,63V and max 0,74V and the other results for R232 is min 0,8V max 3,92.I have also check C80 is still intact.

At min 0,63V at max 0,73V

At min 0,32 V and max 7,32V
