Why did my internal screen on my lm env9200 stop working?

Walt, hold the Fn key down again, and tap once more on the Acer, F5, Display Toggle-Over key.

There are at least 3 display options available;

1) Internal display of laptop ONLY

2) Internal display of laptop AND external display

3) External display ONLY.

Were you just using the external display for more 'display real estate room', or was/is there a problem with the internal display of the laptop?

Was no problem? Is now? Even when using the guidance stated above for the Fn and F5 key?

Then if your laptop uses a CCFL for a Backlight, it also uses a screen Inverter. Screen Inverter is bad.

If it doesn't use CCFL/s for a backlight, and uses LED backlighting, replace the LCD screen.
The LED backlighting is incorporated in the LCD screen assembly, and you ain't replacing it.
Replace the entire LCD screen.

Post the laptop manufacturer name, and model number in a Comment. Model number is on Bottom of laptop.


Try to hurry as I'm going to a meeting with the head of General Motors, (Obama), and later with Bill Gates.





OH I'M JUST KIDDING!

Your laptop may have a combination of problems. Since the laptop was dropped, it is possible that your may a motherboard that no longer outputs video through the video controller, or the screen may have been damaged internally. Try hooking up an external monitor through the vga output of your laptop, usually located on the side or back of the laptop. If the external monitor works, then most likely it is your screen that's bad, if the external monitor doesn't works, then most likely it is your motherboard that's bad.


Let me know if this helps.

So connect your laptop to an external screen. Turn your laptop on. Press start key on your keyboard and then press "P" key on your keyboard. Remember you must press them simultaneously. A small window will popup. Choose Computer Only. Hope it helps I assumed that you are using windows 7 or vista Do not forget to rate your answer.

It sounds like the actual button switches are going bad. Those would normally be replaceable id you can find an electronic tech that is competent. The internaal backup battery may be bad causing loss of the songs. One would have to look at the switches and find a substitute supplier. These switches are often very tiny about the size of a pencil eraser and are actuated by the larger buttons on the panels. You can probably find them at Digikey.com or Mouser.com. They typically cost about 30 cents each... Disassembly and desoldering and soldering qill be required. The internal parts of the switches wear out.

The smaller container in the back under the release handle it the cleaning solution resevoir. The larger one in the front is for the hot water. It has an internal bladder that holds clean water in this larger container, while returning the dirty to the outer bladder chamber. Both need to be filled with water at the very least in order for the machine to work. If either goes empty, the machine will stop working.

Look at the rear of the set by the antenna input for a small black slide switch. That is for internal or external speakers. I bet you bumped it to external. Slide it back to Internal.

Then the screen has failed, though that would be obvious.

reset it

You don't say if this is a laptop or a desktop. I am going to assume it is a laptop and tell you that one of the Function Keys (F7 or so) will turn off your laptop's monitor, such that you can use an external monitor, for giving demonstrations,using Visio or another type of application that requires a larger screen than your laptop's screen.
So, it is a triple toggle type switch, such that hitting it once, turns off the internal screen. Hitting it twice turns it off while the external screen is working, and hitting it a third time, allows the internal screen to work while the external screen works, too. That way, you can see your external application working, while you're able to focus on the application on your laptop itself.
See if this is the case, that you have it toggled to turn off the laptop internal screen.

A blue screen suggests no input signal, or a signal that the electronics in the screen can't handle. I don't think you need the remote, but, it may help. I suggest you try the dvd on a working monitor and check that it's a compatible output. The LM-S6001 is a multi-system monitor both NTSC(US) and PAL(Europe/Aisa). The monitor has a composite video (usually yellow) and RCA(phono) input and DIN, the manufacturer is unclear if both plugs are present. You can assume it's auto-switching, but that may not be the case. More information is needed to fully understand your problem. 1. make/model of DVD. 2. description of external plugs on monitor.
