Laptop screen flickering diffrent colours

SOURCE: 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.

Good afternoon!
From what you've described, I'd suspect that the video chip is starting to separate from the mother board. This is not an uncommon happening with the T41s. In fact, I have personally had it happen to me. So much for the sad story, but what do we do about it?

First, we do some diagnostics to verify that this is the problem. The next time this happens, try pressing down on the following location of the keyboard area. Place two fingers of your left hand on the keyboard cover, just below the left end of the space bar and and to the left of the red and blue mouse buttons. Firmly press down and see if it will start working again. If that doesn't work, try placing the thumb of your left hand in the area that you placed your fingers. With the fingers of your left hand, reach around and firmly lift the lower left hand corner of the laptop a little bit (maybe 1/8 to 1/4 inch). This will flex the motherboard and can cause the video chip to properly contact the motherboard.

If this works, you have pretty much verified that this is the problem. Also, if this seems to work, get back to me for a possible short term fix and what needs to be done to fix it permanently.

One other word of advice, if you haven't done it yet. Back up everything that you need to save, just in case.

Will be waiting to hear from you and have yourself a super day!

1. First since it is only 3 months old. Bring it back to where you purchase it so that you can avail of the warranty.
2. If for any reason you cant do that then try the following

• Turn off your laptop
• remove the LCD bezel by removing the rubber and screws
• try to reinsert the cable that attaches the monitor to the INVERTER. The inverter is the one lighting up the screen. Usually this is located at the bottom of the screen
• if this doesnt work then try to remove the LCD panel and reinsert the flex cable located at the back and see what happens

Hi - I have replaced lots of LCD screens,it can be done

HOW TO REMOVE LCD PANEL OF MY ACER LAPTOP.

First ===>>> Remove all power and battery

Each machine is different in construction and size,
but they operate in the same fashion,motherboard,power inverter,lcd panel and cable connecting them together,also there may be a wireless aerial and or camera as well inside the lids frame housing the lcd screen so be careful while dismantling the front frame,it should be a good tight fit,

the lid has a base and a front panel covering the workings of the screen and wiring in a compact frame,remove the screws from the front panel and lift the front frame free from the base,remove the power panel by the screen next to the keyboard this should expose the motherboard insides,then unplug the inverter from the screen,unscrew the screws holding the the frame and carefully lie the screen on a flat surface to unplug the data cable from the rear of the screen, top of the screen rear contains IC chips required to make the pictures,
DO NOT TOUCH THESE >>> STATIC KILLS

It dosent mater if the screen is already dead just remember this when you fit the new screen

Hope this helps,Misterdj

SOURCE: screen flickers and goes black on my samsung R700

I have found the problem with my r700 screen flick. If you hold the sides of the screen and pinch them it brightens which is a loose conection. This is a fault witht he design. You may notice that its quiet stiff to open the R700 screen and this puts stress on it. seeing most people open from the centre this bends the edges causing a loose conection.
You need to take out the LCD and check all conections are all in ok. Then make sure the LCD is firmly in place before putting back together and tight.
Mine is now working like when i bought it.
HAPPY DAYS !!!!!
