Laptop screen flickers then goes very dark - Computers & Internet

Posted by on

  • rexterdexter Apr 07, 2009

    Hi, I have a Samsung R700 laptop (17" screen) which has a faint flicker, almost like the LCD panel connection is about to fail. Similar to a fluro light tube flickering before it finally blows. Once the screen did go black but I could still see that the screen was working perfectly (except for the LCD panel that had turned off). I rebooted the laptop and it worked OK, but the faint flicker is still there. If it's the LCD panel, how would I go about seeing if the connection is loose? It's still under warranty but I'm concerned that they dont fix it as it's an intermittent problem and easy for them to say it's fine and there's no problem.

    Many thanks in advance.

Hi,

The flickering of the screen is caused due to the problems with the inverter.

Inverter is the part which provides the power to the backlight.

Sometimes you may see a white color on the screen.

In this case the connection between the motherboard and the monitor may be damaged.

To solve this problem, replace the inverter with a new one and also repair the damaged connections.

Did you check the sleep mode or power off mode? What do you do to make it come back on? Sounds like it might be getting too hot and/or going bad.

Sounds like a loose connection at the inverter board. Laptops use an inverter to step up voltage to drive fluorescent tube(s). The problem could be at the inverter or at the tubes.

THE SCREEN FLICKERS ALL THE TIME, HOW CAN I FIX IT


The screen flickering could be the screen inverter starting to fail. The inverter sits under the screen behind the bezel, it takes the low voltage DC power from the power adapter and converts it to high voltage for the screens backlight. If the inverter starts to fail, you either get a dim display that finally goes dark or get flickering like you see in some store lighting fixtures when the flourescent bulbs are failing.

most likely inverter issue, or somewhere in between inverter and LCD, illumination bets thing to do is to take aprt the LCD frame and disconnect and reconnect all wires leading from the inverter. If that doesn't work, the replace the LCD wires and or inverter.
