To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

I have a Plasma TV with black screen and 6 red light flashes.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

Samsung monitor blue flashing light, black screen


Hello,

The picture board of your monitor has developed fault. That is why the screen is black.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity, because the fault is not something you can fix in other not to complicate issues..

The repairer will help diagnose and replace the faulty picture board and your monitor is back and better.

Take care.

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.

My pictures are black i cant see anything when i try to take a picture


Your pictures will usually come out black if you're taking those against the light. Check the lighting or your flash (esp. when it's dark - flash is needed). You should know if your camera is for indoor or outdoor use.
