Acer Aspire 5610 LCD backlight problem

my laptop is acer extensa 4620 problem is web cam is not working what will do

Once connected the LCD press Fn + F8 to switch the monitors. You cannot use both the screens at the same time.
If pressing Fn and F8 does not help Try other combinations of function keys with Fn

looks like you have lcd backlight lamp bad, you can try connecting external monitor to make sure the computer boots up, also you can use flashlight to shine directly on lcd screen to see if there are any images showing, if that works you can order backlight lamp from ebay replace it and enjoy ;) if you never fixed electronics before do not try to do it yourself, find somebody who knows how to do it, it is tricky

You need to fix the boot manager problem first by connecting an external monitor to the laptop so you can see and do a system repair.

As for the backlight problem :-
You could have a faulty CCFL lamp or inverter, To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

sounds like a bad video card honestly. I doubt the monitor was bad.

To determine if you have a video card problem or the LCD screen is at fault.
Connect an external monitor to the video port on the laptop and boot up your laptop, if you get a display on the external monitor then your video card is OK and you have a faulty LCD.

When you power your laptop without an external monitor and have a close look at the LCD screen at and you see a slight image then the fault is with the backlighting panel. This fault could be a faulty inverter or a faulty CCFL backlight lamp.

Defective CCFL backlight may has the following symptom:

• Screen flashs on red/pink and off.
• Picture stays on in red and slowly be come normal.
• Picture flickering with dim display.
• Picture flickering on and off.

The inverter can be easily replaced so can the CCFL lamp (but requires a lot more work)

Attach a external monitor to the laptop, it will have a VGA connection on the back or side. You will need to press, function and one of the F keys, F5 or F8 which are standard ones. So function and an F key. This will rotate the display from the laptop to the monitor and vice versa. If you get the display on the external monitor then you have an LCD or inverta(controls power to LCD screen) issue.

If there is no display to the internal or external, then you have a bad motherboard.

Mine does this too. It is the inverter. Of course it goes wrong as soon as your warranty expires. It can result from Best Buy sending you the incorrect battery and them insisting to put it in even though the voltage doesn't match...

You need to replace the inverter. This page should help:

There is settings for your screen in the display options. Sounds like you need to fix a couple settings.
