Hey... someone else on another site helped me out when I had the same problem. The thing is was that some of my buttons were stuck... check to see if any of your buttons have got caught underneath the remote face. Hope that helps.

Monitor goes black - green light stays on


My screen is black, why do I not have a picture?
Answer Antenna is not hooked up to television.
  • Make sure that the antenna cable is correctly connected to the television. If it doesn't work there appears to be no signal.
Problem is caused by television broadcast
  1. Push 'INFO' button.
  2. If the screen shows channel number (1, 2, 3, etc) try another channel. Not all channels broadcast at all times.
  3. You may have a signal problem. Contact cable provider or local broadcaster regarding the specific channel.
Television is in EXT or SIDE mode, and there is no external source provided, so screen mute (black screen) is activated.
  1. Push NEXT SOURCE button on the remote.
  2. On the screen appears all sorces.
  3. Press the UP button to switch to the TV mode.
If you are using an accessory device (DVD, DVR, or VCR), be sure the device is on and running.
Blank screen when connecting to the accessory (DVD, STB, PC) device via HDMI to HDMI.

Answer
  • Make sure the cable is well connected .
  • To check which connection is selected, Press the i+ button on the remote control.
  1. When you see Blue mute / blank screen and the i+ display does not indicate any video resolution indication then there is no valid signal detected.
    • Make sure the HDMI output of the accessory is valid by changing the video output resolution to a resolution which the TV can handle.
  2. When you see a blank screen and the i+ display shows a video resolution indication then the connection is correct.
    • The blank screen is caused by the accessory device and not by the TV.
    • To detect and remedy the problem caused by the accessory device, check the instruction manual of this device.
  3. If the problem remains : reselect the HDMI external source input by changing to the other HDMI input and back to the connected HDMI :
    1. Press AV on the remote
    2. Press up and then ok
    3. Press AV again
    4. Press down and ok
    5. The compatibility check process between TV and accessory device will start over again.
  4. Reset (switch off and back on) the TV and also reset the accessory device.

When I press light buttopn in the middle the display goes blank


This sounds like a simple battery replacement. Depending on how low the battery is usually pressing the light button and the display goes dim or blank is a good indicator of this. Takes a CR1616 battery and be careful of the spring inside and make sure the seal is in the correct position. You will need to touch the AC button and the back of the battery with a pair tweezers for a couple of seconds to reset the watch. Put the case back on and set the watch thru the functions.

Screen goes blank momentarily


cover up the infrared remote sensor on the projector. The heat of these colours or something might be messinf with the infrared remote sensor. TRy this and see what happens. It may just be bad contacts. Some projectors just cant handle stuff like this. Some were meant for presentations and presentations only. BUt seriously try covering the remote sensor to see what happens. If it is an older projector the infrared signal detector might be sensitive to bright light or stuff like that.
