Initially LCD monitor would go on for less than a minute and go black with power light green. Replaced all the caps, including the 120uF-400v, since several had leakage, but mistakenly reversed the polarity on one of the 470uF-25v caps. Powered up with no light and blank screen. Found my mistake and corrected the cap. Also replaced the one fuse. Still black screen with no power light. Check the voltage output of the PS and got 5v on the last two poles, which I should have. Then I put the PS back in and plugged in all the wires. Still black screen and no power light. Checked the voltage PS output and got 1-2v with it oscillating between the two values. Unable to measure with caps effectively with my analog volt/amp meter, but tested the old caps and got a reading of about 0 ohms climbing to very high. Found none that were different than this. Any suggestions? Wondering are there any other caps besides what is in the PS?
