I have two of these
One is a v2. pcb, the other (giving me problems) is a v1. pcb
The issue is with the keyboard.
AT POST, sometimes the mobo will issue a beep or beeps, flash the num, alpha and scroll lock leds and I will lose the keyboard.
Naturally enough I thought this was down to bad caps
Sure enough, albeit the caps did not show bad phy. signs or bad ESR,
I replaced both the CPU I/P and O/P VRM as well as all the 10V 1000uF
caps on the mobo. All the other caps are 470uF or under.
Post recap, the issue still persists.
I tried testing the ESR all of the remaining caps and found four or five
that had suspect ESR in cct. I took them out and tested the ESR again.
This confirmed my suspisions.
Post recap, the issue still persists.
Checked the solder work on the superIO IC - this is good (appears ok).
Any other suggestions from forum members?

But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though.
