Hanon monitor
Of unknown origin, probably a work reject, I have been using this for a couple of years now. Recently it has not been coming back to life after the PC has gone into sleep mode. Just a very brief flash of the screen then nothing. OK first thing in the morning though.
PSU capacitors looked OK but I noticed one had been changed in the past. Took them all out and one was off on capacitance and ESR around 5 ohms, all others around 0.2 ohms. Changed it and now everything is hunky-dory again. It was a capacitor in parallel with the previously changed one. Gordon |
