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

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.

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.

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.

I have connected via HDMI and the display on television was fine but not on laptop. Doe this mean a possible LVDs fault?
Sorry that it was not better news but thanks for the update Carbonite
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.
