Ok, good. Just wanted to verify the PS was definitely what was buzzing.
I guess now we know what we needed to so put the bad PS back in and test the voltage at that resistor and see if it falls and what it falls to. I would also like you to recheck all the voltages on the connector to be sure they are all right where they should be.
Well MT we have a slight problem, R214 on the bad PS popped off when I went to put the test wire back on it, and to make matters worse, one of R214s ends came off too, so the resistor cannot be tested for its rating...
R213 which is right next to it is 1.2K, I don;t know if R214 is the same or not, but these are so small they are no numbers on them. I'll throw another 1.2k in place of the bad R214 and do what you asked and see what I find out.
Results of testing the + voltage on R214, when in standby its at 4v, when powered on it drops to about 3.6, when the lamp lights up it drops to 2.9, it made it down to 2.8 and then the projector shut down and went back into standby.
