Research BAD CAPS and now you know what to look for inside that display. BEWARE THERE CAN BE SOME HIGH VOLTAGE inside so do not work on it unless you know this.
For me I get lucky about the BAD CAPS too often to not look for that issue.
My sceptre monitor will come to life after moving the mouse to get the computer out of sleep mode, but then goes black after 2 seconds. I turn the monitor off, then back on, and the same thing happens again. It started a few weeks ago. Initially it would go blank/black, I'd turn it off, then on and it would work fine. After a few days it took turning it on and off 2,3, sometimes even 4 times before it would respond and stay on. I used my 19" tv as a monitor and don't have any problems with it. Right now I'm using my origional dell crt monitor with no problems. Is the Sceptre monitor shot?
