Re: SC502 With Display Issues


Transistors Q935, Q940, Q960 replaced. No change...

Since I’m at a complete loss, I decided to look at the other end, from the power switch, which is located on the opposite board (A2), and look for any signs of burns or discoloration. So far nothing.
Is Q400 supposed to have it’s collector to ground no matter the position of the selector switch?
I see Q405 is, but Q400?
