Hi,

Try lowering your laptop's screen resolution and refresh rates to the lowest possible.

Additionally, you need to press Fn + F? keys on the laptop to cycle on laptop display, laptop display + external; display, external display.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

If the menu isn't coming up then the TV video board may be faulty as otherwise it would appear. If you can still return you should go to where you bought it and ask for a replacement.

you might need to turn off your computer .
then connect the data projector
and turn on data projector
then turn on computer
hopefully it detects the data projector is connected and switches windows to duplicate projection
On my P.C. F4 key in windows Switches the display manually to duplicate, alternate screen or pc screen only or projector screen only.
As I am not familiar with Apple this support article below might explain the switching of display outputs available on Apple Mac.

1.Press the MENU button to display the menu screen, and
then press the F or G button to select the OPTION menu.
2. Press the ENTER button, and then press the F or G button
to select LAMP RUNTIME.
3. Press and hold the ENTER button for approximately
3 seconds. The confirmation screen, “LAMP RUNTIME
RESET.” is displayed and select OK.
4. Turn off the power.
�� This will reset the cumulative usage time for the lamp
unit to zero.
***Here you go and best of luck!***

1) Press the RESET button on projector for 3 seconds or remote control TIMER button for 3 seconds and display the total lamp used time. 2) Press the RESET button on projector or remote control MENU ON button during displaying the lamp used time. 3) Select the ?0? on the screen using the MENU ( ) button or DISK PAD.

Give input signal to the projector and see that if the menu appears or not on the screen.
if menu comes on the screen then put the backgroung color to blue, instaed of black.

if nothing comes on the screen, then the LCD panels are faulty.

When you first replaced the bulb it went back on and then later it did not. Most projectors have a safety switch that it is activated upon the bulbs cover placed. Once the cover is removed it activates the switch and shuts down power to bulb. It sounds based on your remarks, that this switch may have intermitten problems. I would suggest, locate this switch and verify its operation. Or, make sure the bulb cover is placed and/or secured properly.

OK, found the solution on the net, you have to use the buttons on the projector instead of the remote to access the menu item.

go to menu and to screen and adjust brightness and contrast
