When this set was first plugged in it turned on by itself and if you push the power button you would get color and sound. If power button pushed again to turn off the color goes out and sound goes off but black and white picture stays on. On inspection found R431 and R432 burned also found Q400, R437, ZD405, Q420, and D413 all bad. Replaced all bad parts along with D415, D416, ZD406, Q410, Q404 and Q403, because after replacing all these parts I still only have about 1.9 volts DC on the emitter of Q410 which is the 5V standby REG. I do have 39volts on the cathode side of Z402 which connects to R402 but on the other side of R402 I only have 3 volts (should be about 7.7volts). I am at a odds on this set does anyone have any other notes? I checked the website for techassist but it only had things I have already replaced. Thank you.
