SOURCE: 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.

SOURCE: 42" philips plasma

when a television turns off by itself and flashes as you say, it indicates that there is a problem inside the tv. If you keep trying to turn it on you may do more damage. It could be something as simple as a faulty fuse inside. If you have no expierience with electrics I suggest you get it checked out by a professional. I had a similar problem with another tele model and it was the fuse in the back of the tele that needed changing. I did try to this on my own but unfortunatley didn't have the right fuse so i took it to a repair shop and he done it really quickly.

Hi there! The panel may be in protection mode. The Inverter board is the most logical area to start after checking power supply Voltages.(5,6,24 and 13Volts). There may be coils on the Inverter Board which have bad soldering or faulty. Other than this it may be main board which controls switch on or off. If all else fails, refer to a repairer. Beware of High Current!!! Best Wishes and Good Luck, Jus004

Green light, black screens, no sound, needs new battery???


The alarm is just a coincidence i suspect, green light comes on and stays on probably not the battery at fault. It would be red.
If the green light goes out and screens just flash one of your screens are at fault or a loose ribbon connection.

Acer AL1914 black screen, green light


it sounds like a deleted driver? try getting the driver for the monitor, did you loose the Operating system at some point, if so try a system restore to a date when the computer was working properlly prior to the malfunction. It sounds like it restored you to a time before the driver for that monitor was installed.
