Hi everyone,
First time posting after spending the last few days reading.
I have what seems to be a reviveable Vp201s. The syptoms are a black display with a steady green power LED that turns amber when signal is removed and back to green with a valid signal.
After reading the few existing threads on the VP201 monitors, I have opened the monitor up, verified that the power supply is outputting 18.25 Volts and on the inverter board confirmed that one of the surface mount fuses passes the full 18.25 Volts and the other fuse only 3.5 Volts. To me this would indicate that the fuse needs replacing.
My real question being... in the experience of those with much more experience than I, is there anything else I should do while I have it apart. I have read many reports of questionable caps and checking the ESR. My display does not seem to have any of the listed marginal caps. The power supply caps are all Nichicon, and the inverter board caps are all Rubycon. They all look like new with no bulging or leaking. I don't have access to an LCR/ESR meter, and buying a $100+ meter to check $5 worth of caps seems a little rediculous. Is there any reason not to just replace the fuse and call it a day??
