Question about Sceptre DCL9a
When my pc boted this morning my monitor had a white screen nothing else. i disconnected it and when i reconnect the power wire. i astill have the same white screen and the buttons on the front do nothing. I hooked up an old CRT and have no problems with the screen.
Inside the case you will find 2 PCB's. One is a controller and the other is your powersupply. On the power supply look for some Radial Lead Electrolytic Capacitors. Replace any that are swollen on the end or deformed in any way. Electrolytic capacitors can go bad over time the swelling is an indication of this. I have the same model screen as you. I replaced 3 capacitors that were swollen and this fixed the problem. You will see 2 values on the capacitors ####uF ##v. The first is the microfarad value this should be the same value. The second is the voltage rating it can handle. As a general rule these capacitors should be rated at twice the voltage they handle.
Sometimes increasing this value can reduce the chance of repeated failure.

I had the same problem, and putting in bigger capictors, solved the problem, they were 16 volt before, we replaced them with 35 volt capictors.

Hi Guys, I solved this problem by turning off the power saver settings. Make sure its off and sleep mode is off. Then reboot, monitor should work. One more thing. Never shut it off!
