> Help???
>  When I unsolder pin 23 & pin 24 on micro.(U13101) I get real good clock &
data pulses coming out, but the DC voltages are low.The DC voltage on the
pads is 4.9 volts , but when I reconnect, I only get 1.6 volts on pin
23(data) & 2.29volts on pin 24(clock). The micro seems to be holding the
voltage down.I don't have anything coming out of pin 19(run/stby).The micro
costs $49.00, and I am trying to make sure it is really bad before I get a
new one. I dont see many of projection sets here and won't need a spare
micro if this is still good.
