Hey all!

Just need some advice on the fault im getting with my laptop. It is intermittent fault but happens more often than not. Once it does sometimes it fixes itself on Windows or like the video not. If it happens I remove battery and AC and drain the power til it works (not always) I dont seem to have any issues gaming once it works and temps are fine.

Please see video link below:

Any help would be appreciated

Thank you,

Michael

Hello Carbonite,

 

Have you tried connecting the notebook to an external screen to see if you get the same problem.

Hello Phil,

I have connected via HDMI and the display on television was fine but not on laptop. Doe this mean a possible LVDs fault?

It looks like the LCD panel has a column driver fault. There are tiny integrated circuits called column drivers embedded in the looms that carry drive signals to the Liquid Crystal matrix inside the panel. Each one drives a column width of pixels, your screen appears to have two faulty column drivers.

 

To confirm this, change the screen resolution to a lower setting, if the faulty columns remain the same size and position, the screen will need to be replaced.

Yes, the image being sent to the screen changes, but the position of the bars stays the same. It's in the LCD panel.

Is it possible to haves fault/loose connection? Is it worth taking the LCD area apart and reconnecting everything?
Or is my only option a new LCD?

Thank you

If you wanted to open it up and try, that option's always there, but that symptom is 99% sure to be the column driver ICs.

Okay thank you.

So I would just need a replacement LCD By the looks of it? No inverter board or anything like that?

You should open it up anyway to check precisely what panel is fitted to that unit. Laptops and monitors can have different panels fitted in different production runs or different production facilities, depending on part availability at any given time. There may be different inverter modules or connecting cables for differing model of panel. Getting the exact correct one avoids problems, and you can double-check connections to the panel, even though they shouldn't produce that particular symptom.

Sorry that it was not better news but thanks for the update Carbonite  :thumbup2:

 

The rather basic external screen test being ok would normally suggest a bad notebook screen but you couldn`t ask for a better diagnosis than that provided by Platypus, if you post the brand and model name or number of the notebook we can take a look for a replacement screen and fitting instructions for you.

If you can confirm which connector, you can probably track down equivalents, e.g. for 40 pin:
