Your TV might just have a blown capacitor? It also can be a bad power supply not powering up the screen. The Backlight might be burned out but in my experience it always is a blown capacitor in the main board. If your handy with opening up the TV, look for a can like component that might be all black in color oozing a yellowish grease like substance? Replacing a blown capacitor is quite easy by just desoldering it and replace it with a new one of equal values.

Lcd tv's Do that when the backlight bulb is out. There should be a small panel on the back. Order a new bulb and replace it and it should work fine.

We bought 6 Pelco PMC10A Color Monitors and they are working 24 hours a day. Suddenly after the warranty was over, the screen went totally black on 3 of them. After searching a while for the cause, Pelco seems to have used the wrong capacitor on their board close to the fly-back. They used a catalytic capacitor G-LUXON 4.7uf 50v and they have all busted by just looking at it on the board. I replaced the defect capacitor with a 4.7mf/250V Metallized Polyester Film Capacitor for about $2 each. They are now fixed! Hope this will help someone that has the same problem as I did.

I have a Peloc 500 series monitor 32 " that seems to have a power isue. The power led stays an orange/red color. I have left it unplugged for quite some time to let it cool down, but made no...

I have never work on this model yet, but the power supply voltages and caps will be the first palce to look. May be you should open it up and inspect the pwoer supply module first.

Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

I have a pelco pmcl319 19" lcd monitor. when i switched it on the power (LEDlit) stays blue but it has no display. hope you have a solution for this. thanks.

First thing I would recommend is to get a flash light and shine on the surface of the screen where the Pelco name normally appears when first turned on. Next press the power button and watch at the center of the display. If you see a gray image of the Pelco name then the ccfl backlighting is no longer functioning. I have been able to order replacement ccfl lamps and if need be inverters that drive those lamps. These part can be purchased from Disassembly of the LCD display is required as well as some soldering.

Monitor wont turn on. is there a fuse of some sort inside? or any other minor issues i should check?

There is always a fuse inside and if it is blwn, there is something else that has failed. Check the power supply caps also. Common failure.

Screen went black

I am working on one right now with a similiar problem. The power supply is bad in the one I am working on, and sadly, the part is not made anymore. I hope you have better luck than I am finding the bad component in yours. Sorry for the negitive answer.
