Screen Flickering on Acer 3680-2682

I bought an Acer 3680-2682 few months ago. Computer was working perfectly until i tried to connect an external monitor (TV) using the S-Video hook to it. When i did this the screen on the laptop went crazy and all the display setting were changed automatically. Immediately i stop what i was doing and set the screen and display seeting to their defaults. By then the computer worked well but when i restarted it i noticed the monitor start flickering at start-up, up to 3 times until i finally stops. Everytime i start the computer when it is almost completely boot the monitor starts flickering. It does the same even when waking the system up from sleep mode I tried to solved it using the system restore but it didnt worked. Have you heard of soemthing like there any recommendations???

Re: Screen Flickering on Acer 3680-2682

Ok we must remember when we setup any device on our PC, one of the many non PnP devices is and LCD Monitor, your PC should always be shutdown before installing a new Monitor. If you did not do this you could have damaged the I/O port on your PC. Not a definite, but possible! When you plug up a monitor or any serial cable while the PC is still on, it is of a low voltage which can casue some issues for you! Sounds like this one is yours!

if you activity lights on, try connecting to an external monitor or modern flat screen tv. if the screen is flashing then it is probably a screen issue. eg the invertor r screen has failed.

Hello there...

Best advice i can give you is to plug out your HDD and backup all the data you want to keep using a external casing or plugging it into another computer, and then format your laptop.

THis happened to me a few months ago, i tried everything, untill it came down to formatting my laptop. Really hope that this can be of help.

Best regards

To determine if you have a faulty LCD screen or a faulty video card, connect an external monitor to the laptop's video port, power up the external monitor first the the laptop. The video output should automatically switch to the external monitor. If you get a normal image then the video card is OK, and the fault is with the LCD screen.
If you still get a bad image, then the fault could be a faulty video card or video RAM. Most laptops use part of the main RAM module for video RAM, try reseating the RAM modules and or test the RAM modules. If the RAM is OK then the fault is the video card.

Acer Laptop Screen Flickering

The flickering screen indicates that it is a backlight problem with either a faulty inverter or inverter connection problem. The inverter is usually located at the bottom edge of the LCD screen, and may have one or two connectors (one for the video info. and one for the inverter power or a combined connector) attached to the motherboard under the case near the top edge of the keyboard near the hinges. Reseating these connectors may solve your problem.

Black screen on Acer 5100, but will work with external monitor

It sounds like the control board or cable for the LCD may be damaged. If you're still under warranty, you'll need to send it back to Acer to be repaired.
