I have a Toshiba Satellite 17" Laptop. A 32 mm strip of white running from the top of the screen to the bottom has established on the left hand side of the screen. Another 32 mm band is forming (flickering ) 32 mm away from the first i.e I have two white strips separated by a 32mm band of desktop. Suspect I will be looking at a prison-bar situation soon. As we live in Seychelles, our repair options will inevitably involve a teaspoon, some tissues and a toothpick. Before I open 'er up, I'd appreciate any insights as to what I am (or not, in this case) looking at.... Cheers CO'B

A compact, practical checklist and safety notes for the vertical white bands described, and to build on ’s diagnostic direction.

  • Quick interpretation: vertical bands usually point at the LCD panel electronics (column drivers or the panel’s timing/T-CON board) or the LVDS cable/connector that runs through the hinge. Backlight/inverter faults usually affect overall brightness or cause flicker, not narrow vertical white strips.

  • Simple tests that give good clues

    • Observe the screen during boot/BIOS and while changing the lid angle. If the bands appear before the OS loads or never change with angle, the panel/T-CON is likely. If they change or flicker when moving the lid, the cable or its connector at the hinge is the probable culprit.
    • Gently press around the bezel (soft fingertip) — see if the lines shift. Do not use hard or sharp tools for this test.

  • If you decide to open the lid

    • Only proceed if warranty is void or you accept the risk. Use proper tools (precision screwdrivers, plastic spudger) and avoid makeshift metal tools like teaspoons or toothpicks — those cause damage and ESD risk.
    • Reseat the LVDS cable and inspect the connector for bent pins or foam damage. While the panel is out, photograph the label and note the full part number; that exact number is needed for ordering a replacement.

  • Repair options and practicalities

    • For remote locations: photograph the panel label and ship that info to suppliers — often a replacement panel + DIY swap is cheaper than local repairs.
    • If under warranty or unsure, contact an authorised service centre first. If not, a local technician can often swap the panel or replace a hinge/LVDS cable.

Safety note: avoid poking, prying or using conductive household items. Small, careful tests will usually tell you whether the screen itself must be replaced or whether a cable/connector repair might fix it.

It looks like the screen is wearing out. How long have you had this laptop? Also, have you dropped it recently or has any liquid got into it? I think the screen is the problem here.

Thanks GL.
The bars do not appear when the laptop is attached to an external screen so, we are thinking screen defect - not uncommon apparently. The machine is less than 1 yo. Chrs

I would think about getting a new screen, or a replacement of some sort. Seeing as it's less than a year old, i think your warranty should still cover it. Take it back to where you bought it from, explain that the screen is broken, and i'd like a new one.
