I pressed the power button for 5 seconds and there is still no picture

Just wanted to confirm a few things..
Did you do a hard power down by holding the power button down for 5 seconds or by just briefly pressing the power button (which would put the computer to Sleep).
I've found this laptop occasionally does not properly recover from Sleeping under Win8, that's why I ask.
Either way, do a hard power down by holding the power button for 5 seconds.
Unplug the laptop and find the battery disconnect pinhole switch underneath (indicated with a picture of a battery lifted up) and using a paperclip press and hold for 30 seconds.
Try powering on again, do you atleast get the Acer logo appearing when powering on?

It is nothing to lose to try this:
1. Remove the battery (the charged and good working battery),
2. Switch the power to ON position,
3. Press the shutter button for 5 seconds.
4. Switch the power to OFF position,
5. Insert the battery,
6. Switch the power to ON position,
7. Try to take a picture.

Please post the result here.

The lamp hours might have not been properly reset.

1. Press the "POWER" button so that the projector projects the picture on the wall (projection screen)
2. Press the "MENU" button to show the "MAIN MENU"
Use buttons "F" or "G" and select "OPTION"
3. Confirm this by pressing "ENTER" so that "OPTION" is shown
Using buttons "5 / 6", select "LAMP RUNTIME" (lamp operation counter)
4. Select and press the "ENTER" button for at least 3 seconds
5. The "LAMP RUNTIME" (lamp operation counter) will change to "TIME RESET[POWER OFF]"
6. Turn the device off by pressing "POWER" and unplug the power cord.

You may have not reset the lamp counter after replacing the physical lamp. To do this 1. Press the “POWER” button so that the projector projects the picture on the wall (projection screen)
2. Press the “MENU” button to show the “MAIN MENU”
Use buttons “F” or “G” and select “OPTION”
3. Confirm this by pressing “ENTER” so that “OPTION” is shown
Using buttons “5 / 6”, select “LAMP RUNTIME” (lamp operation counter)
4. Select and press the “ENTER” button for at least 3 seconds
5. The “LAMP RUNTIME” (lamp operation counter) will change to “TIME RESET[POWER OFF]”
6. Turn the device off by pressing “POWER” and unplug the power cord

Here's the basic troubleshooting:

1. Make sure that no front panel buttons are inadvertently stuck in an "engaged" position.
2. Disconnect ALL devices from the TV.
3. Press the SYSTEM RESET button and hold for 10 seconds. Proceed if the problem still exist.
   
4. Press and hold POWER and MENU buttons simultaneously for 20 seconds. Proceed if the problem still exist.
5. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours.
6. If it still shuts down, press the DEVICE and MENU buttons on the front panel simultaneously and hold it for 5 seconds to activate the Error Code Operational Check. The status LED indicator will then flash denoting a two digit code.
   
7. Count the number of flashes then pauses for about a half second then flashes again. The first number of flashes indicates the first digit of the error code and the second number of flashes indicates the second digit of the code. For example, if the error code is "35", the LED will flash 3 times, pauses, then flashes 5 times. The error code is repeated a total of 5 times.

Please let me know the code you got and I'll tell where the problem lies and how to fix it.

You probaly turned hdmi on or off i dont know what your settings is,

you can turn your system settings back to factory default using the Safe Mode.

Step 1: Turn off the PLAYSTATION 3 by holding the Power button on the front of the unit till the Power light is red.

Step 2:

1. Touch and hold the Power button, you will hear the first beep, meaning the PLAYSTATION 3 is powering on.
2. Continue to hold the Power button and after about 5 seconds, you will hear a second beep, indicating the video reset.
3. Continue to hold the Power button and after about another 5 seconds you will hear a third beep and the system will power off (Power light is red).

Step 3:

1. Touch and hold the Power button, you will hear the first beep, again for the PLAYSTATION 3 to power on.
2. Continue to hold the Power button and after about 5 seconds, you will hear a second beep for video reset.
   
3. Continue to hold the Power button and after about another 5 seconds you will hear a quick double beep. At that point release the Power button. If you succeeded in activating Safe Mode, you will see a message on the screen saying, "Connect the controller using a USB cable and then press the PS button."
4. Connect a USB cable to the controller and the PLAYSTATION 3 and press the PS button to enter Safe Mode.
5. Then you will see the Safe Mode menu.
