Acer 77e Black Screen Until Warmed-up
This 17 inch monitor turns on and has HV but the screen is completely black
for about 5 minutes. Gradually, it brigthens up but the images look out of convergence [?] - blurred, colors off, unreadable. After about 30 minutes the picture is superb. OSD works fine. No matter how long the monitor then remains in standby, it comes back perfectly. I'm guessing maybe a failing capacitor in the SMPS and will test with freeze spray. Any better clues/hints/suggestions to limit my hunt would be apprecaited. Thank you. -- Remove -NOSPAM- to contact me. |
