Rca hdtv dlp screen flashing


Sounds like it could be the power supply. Try changing the brightness of the screen and changing picture modes like movie or standard. If this causes the flashing to change in severity, it will most likely be the power supply board

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.

Flash not working


Hi there and welcome to FixYa.

Bad batteries can cause that. The flash module needs alot of power to charge. Your camera will still work, but without enough power to charge the flash module, it may take along time. Again.
Try fresh batteries.

Flashing Power Light


When this occurs an inverter, backlight, vga connectiosn, etc could be the cause, my suggestion is connect it to some other device, if you get the same result then your monitor is bad!

Powerbutton flashing yellow


If the main power button LED is flashing or solid yellow, this could indicate a hardware problem.

 

Was it running good before?

 

Are the diagnostic LED lights all green?

 

Here is what dell says:

 

If the power light is blinking amber  —

 The computer is receiving electrical power, but an internal power problem might exist.

  • Ensure that the voltage selection switch is set to match the AC power at your location (if applicable).
  • Ensure that the processor power cable is securely connected to the system board.

Do you remember what the BSOD said?
