I recently picked up a SX 1050 that would power on but had no sound output. I am not getting the second relay to click. I opened it up and found the F1 and F2 fuses on 104 board were blown, replaced them and still would not work. Fuses are not blowing now but checked the voltages on the 103 board and found most were off. I replaced all the caps and most of the transistors on that board but still have issues with voltages at pins 13,15 and 16. Some of the others are off just a little. I suspect Q1 may be problem. Q1, Q9 and Q12 are only ones I did not replace. I did find a couple of the transistors were bad when I was replacing them. Was planning to go back in and replace the rest of these but thought it might be good idea to ask the guys here that have good working knowledge of these if there is something else I should be looking at.
