Quoted from honkbahh:That was my first guess too, but now the 12v is out. Also, behind Q3 is a very thin clear plastic looking piece the same shape as Q3.
I took updated measurements, and maybe noticed something peculiar?
New readings:
"E4": .11
"E5": .47
"E6" (should be same as TP4): .47
Issue 2 -- high voltage supply.:
"E2": .46
"E1": .68
Resistor R4, end closest to heat sink: Fluctuates .16 to .03
Resistor R4 opposite end: .03
For the heck of it I tested some of the screws that mount the plate to the brackets on the back of the light board, (Not the screws attaching the pcb) and they each had a reading of about .35
I did the ground mod like pic 2 months ago (this is not a pic of my board).
Is it time to yank it out and remove Q3 again? I do fear for those pads a bit. [quoted image][quoted image]
