Got one from Freecycle. Donor says the screen just went dark on day. I plug it in, and it does power up telling me to "Check Signal Cable". That status hasn't changed for the past 10 minutes leading up to this posting. I'm led to believe this monitor had been dormant for quite some time.
I see seven capacitors, all with either the SamYoung or Rubycon brand. There's one I can't identify. I'm using ESR Micro 3.1 testing in circuit.
The big SamYoung capacitor specified for 68 uF and 450V tests for 69 uF and 0.38 Ohms.
There's a Rubyon ZL on its side specified for 470 uF and 25V. It tests at 1375 uF and 0.03 Ohms.
The two SamYoung KMG capacitors specified for 330uF and 25V test at 1370 uF and 0.33 Ohms & 836 uF and 0.15 Ohms.
There's a small SamYoung KMG capacitor specified for 22uF and 50V. It tested at 16uF and 5.4 Ohms. That bothers me.
There's a SamYoung KMG specified for 470 uF and 25V and tests at 830uF and 0.00 Ohms.
There's a T0348 ZL (Rubycon?) also specified for 470 uF and 25 V and tests at 1365 uF and 0.00 Ohms.
I also test what I think is a fuse to the right of the small capacitor and northeast of the capacitor cluster. There *is* continuity.
Anything else I should examine? I keep hearing debates on the reliability of SamYoung capacitors, too.
Thanks for reading!
