SOURCE: Locked

Switch the lock symbol on the bottom of the player to unlock the little button from left to right. That should do the trick.

SOURCE: Monitor goes blank

I was thinking about your problem, I just had a similar issue and the problem is that the inverter or the power supply with an embedded inverter had gone bad.

The reason it goes black is because the inverter fails to provide power to the LCD Display.

The only way to fix this is to open up the FPD:

*note these are instructions for the most popular FPD 1730*

1.there should be four screws on the back --> plus two large screws that hold the FPD stand and the Monitor together.

2.Open the back by pulling the cover off
Remove 7 screws holding the frame and the power button for the LCD

3.Remove two screws through holding a silver cover and remove cables.(pinkwhite) (blackwhite)
Please note where they belong before removal**

4.On the edges left and right are two screws 4 total ---> remove and remove LCD off of frame**becareful because the backlight Damaging can cause severe damage to your LCD panel.

5.Choose your model
Your FPD has 3 boards (power, inverter(backlights) Logic Video)
replace the inverter with well known good one

Your FPD has 2 boards(Power with inverter on edges, Logic Video)
replace the power board with a well known good one

6.Then do steps 1-5 in reverse order(putting your FPD back together.

I hope this is significant help

SOURCE: 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.

SOURCE: the base unit goes blank no display

I had this same problem. It turned out to be a bad power adapter for the base unit. If you have another handset that has its own charger than the power adapters are interchangable. try swapping them and see if this fixes your problem.

SOURCE: Laptop computer connected to projector.

When the projector displays the background image and the lcd displays the desktop as normal you can drag the open windows to the left or right and display them on the projector. it sounds like this laptop has an internal video card. If you right click on the desktop it might give you options to configure the display settings for the video card. Not sure how you will get to it if it does not show up on the right click menu. Probably through the start menu or in the control panel there should be somewhere to change the settings for the video card. This will no be under the display settings though.

But once you find your dual display options you will be able to change it to make both displays the same

When using the computer with my projector my computer goes blank because i am not actively using it just having students view the screen what can i do

"test test" offers a good answer but misses out the possibility that your laptop "Power Settings" might be turning off your screen display. So if the problem persists after going through all the things already suggested you could go to your laptop's control panel to the Power Options and click on "Change when to turn off the display". Good luck.

I turn on the laptop the dell logo boots then the screen goes blank a padlock is illuminated on the panel . What is going on?

You have 3 padlock LED's. They are as follows.
icon_9.jpg Turns on when the numeric keypad is enabled. icon_a.jpg Turns on when the uppercase letter function is enabled. icon_scroll.jpg Turns on when the scroll lock function is enabled.If you don't get a display when Windows tries to load then you probably have a video driver issue. Try to load Windows in safe mode by powering on the laptop and tapping the key. If it works then your video driver might be corrupted or your video circuit has a problem.

Need to see display on both laptop and projector

On most laptops pressing the Fn key plus the F5 key (in your model laptop) several times will cause the video to switch to different options
In the various laptops I've used with data projectors it is the same.
If you plug in the data projector and power it up then the laptop then the Windows image will be on the data projector (provided the laptop's screen resolution matches the data projector).
To toggle between the data projector only, the LCD screen, then LCD screen plus data projector, and or back through this sequence, just press the Fn key and the F5 key to get the displays you want .
