This was the same symptom on a Dell 19" LCD monitor I got and after disassembling it found a
shorted transient absorber diode (ZD15) on the power supply board. This diode is a protection diode between the 5V and 12V output. You do not need it
to be in the board but if you want to keep the same
protection on the board I suggest you order a
replacement from Digikey.com or Mouser.com.
You will need to know how to separate the front bezel from the rear casing to get to the power supply board. I have a picture of the power supply board and the bad part is at the bottom left of the board with the designator ZD15.

The manual does not indicate what is wrong, when the green light is flashing, other than the flash is charging.
It could be the flash can't be charged, because the flash capacitor is defect, or the battery does not have enough power.
Try switching on the camera while not in automatic mode (M of so) or when in video mode. If the light on the main dial still flashes, I think you should look for another battery. But first try another battery, before you buy one. (Or test the camera with an external power supply. Don't forget to switch of the camera, every time you change the power supply.

I have a 26mf231 Magnavox 26 inch tv. The screen on the tv just flashes over and over. Never powers up. I took out the power board and all the capacitors look good. Thanks in advance


How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy.

Screen black. Power light on unit flashes red slowly. Power light on switching adaptor power supply flashed green slowly.


Sounds like the battery might be low which would cause the red flashing light and dark screen. Let it charge for a little bit then try turning it on again. If it still does it with the power supply plugged in, make sure there isn't a lens cover on it, and switch modes or try getting into the menu to see if you can get anything to come up. If that still doesn't work then it sounds like there might be a problem with the camera.

I have a cybershot DSC W55. When the power button is switched on the lens extends and the "access" message shown on screen. Also amber light is flashing above screen. After a few seconds I get a message to power on and off again. I\'ve tried switching on and off a few times, removing battery pack and memory card, but nothing seems to be solving the problem.

Replace the lamp would be the first thing to try. Lamp door switch on this model is notorious for going bad. If you replace lamp and still won't turn on jumper door switch. If you take off back you can see switch board.

On back of the computer is a on off switch for the power supply, or unplug the computer for one minute. Turn the switch back on, or plug the computer back in and try to turn it on.
