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.

My device a red blinking light with a dark screen.


The red blinking light can mean a couple of things. First, It could mean that you have a message. If that is not the case, you caould have on the 'LED Coverage Indicator'. The LED Coverage Indicator tells you by having the top light flash eather Green or Red depending on coverage. If you are in a place that has good coverage it wil flash Green but if you have little or no coverage the LED will flash Red. To check if you have this setting enabled, first go to "OPTIONS" on the phone in the full menu. Once there, go to "SCREEN AND KEYBOARD". Click on 'SCREEN AND KEYBOARD" and scroll down will you see the option that says "LED COVERAGE INDICATOR". Click on that and switch it to OFF if it is not already there. Then click the back bottton and click SAVE. That should work. If it doesnt, I would call your phone carrier and ask them.

Projector screen turns off after 10-20 seconds


Is the projector receiving a source signal? if not it will power itself down after whatever time you have it set to do so when no signal is present.
Just an idea?

The tv will turn on but no the screen wont. and


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.

Ds lite flashes on but fuses are ok


One or both your screens have blown.

Try removing the motherboard from the screens and attach the battery the green light should turn on and stay on.

Now attach the lower screen and turn on. If the screen is ok the screen and green light will flash and then turn off. (if the screen doesn't flash the bottom screen is you're problem and will have to be replaced)

If this happens the problem is then you're top screen which you will have to replace.

Stand by light flashes red on powering up with remote and the green light flashes approx 15 or times before the screen illuminates.


thats pretty normal, it takes a good second or two to warm up and the display to turn on(at least0, you get the green flashes as you hold for on, 1 sec is a long time at times, lol, be patient, no problem with your tv!
