Check that you hooked up all the power supply connections. Try a new motherboard battery as the old one may be dead and the bios is not working. You are evidently not getting a post beep signaling that the cpu, ram, video are good.

I bought a used dell monitor e177fpc when i hook it up to my comp. i get can not support 1280 x 1024 resolution


Try downsizing the resolution, and then try unplugging your adapters. If it's not working still, it's a bug in the drivers, which should be taken to a professional to be looked at.

Dim monitor


Hi

You just bought a new power supply for the monitor? Did you set the B+ voltage to the correct settings. Rebuilt power supplies for CRT monitors are not set correctly at the factory. Use your schematic to determine the proper B+ and then set this under load.

Thanks

It's probably your dc power supply.

Mine would blank just 2-3 seconds after power-on.
I pulled this monitor out of the garbage - someone threw it away. I found any old 12vdc power supply I had laying around (1 from an hp scaner 1250mA, another rated at 600mA) neither could supply the current (amps) required to run the backlights, therefore backlights shutdown, monitor goes blank--monitor stilled powered on, but black.

I tried all of the disassembly, re-solder various solder joints on the LCD Inverter board and removing the heat/magnetic shield from inside the back cover of the monitor. Nothing worked.

I bought a Segate 80gb external hard disk drive that came with a 12vdc power supply, looks like a typical laptop power supply, rated at 3A (3000mA). Plugged it to the monitor, it powered up, and it works flawlessly.

PROVIEW PL-456S LCD MONITOR TURNING PINK ON ONE SIDE


Chances are that you are not hurting anything with the lower power supply. What is probably happening is most likely two fold. 1. The light bulbs in the backlight circuit may just be wearing out and need replacement, and 2. the lower current power supply may not be capable of producing al the current that the monitor needs at certain times during operation. I would suggest getting hold of the correct power supply module and see where that gets you. If you still have the red outs,replace the light bulbs in the monitor. The only other fault than that would have to be in the video controller. Hope this helps.

I had this exact problem with a newly bought motherboard and it turned on but the screen was black, also I noticed once it turned on it wouldn't turn off, (Am wondering if this is happening to you) the motherboard was fine as it is in the other room now working away, so dont get rid of it just yet. Most new motherboards require additional power to the processor from the power supply, through a four pin power cable, which should be availble with the newer power supply units having (number of pins for you motherbpard power supply) + 4 (which is the 4 pin J-connector) printed on the packaging. If this is connected and you are still having problems which for me was the case, then you will have to try a different approach. Cutting the chase, the problem I had that produced similar effects of screen being black when the motherboard was powered on, was to do with my case. It was one of those flimsy aluminium foil types. I came to this conclusion by taking my motherboard out of the case and hooking it up to the cases power supply on an insulated surface such as a cork mat. It then worked fine again. So I bought a good qulaity case with a new power supply just to be sure, hooked everything up and hey presto it was fixed. It turned out that enough power couldn't get to the board as the case was shorting its supply. Hope this helps.
