You watching: Sony vaio laptop screen flickering


It is a Sony Vaio NW series lappeak, 2009 production. Recently the display started turning off when you relocate the lid (the backlight turns off).

However before if you move the lid forwards slightly then it usually comes earlier on. I think this is definitely a hardware problem as it happens both in Windows and also Linux. Is there a DIY settle for this (I have actually repaired desktops prior to so I"m not too afrhelp to take the lapheight apart)? or is it a pro repair only?

As has been declared, a loosened or damaged display screen wiring harness might be the reason of the problem, gave the lapoptimal has actually suffered some influence. They do not work-related themselves loose over time, as tright here isn"t that sort of stress on them in the method they have been assembled. I"m not saying it is impossible, just that it has actually a low probcapability.

Replacing a display screen inverter is essentially just as facility a job as replacing a wiring harness. You"d need to remove the bezel around the display, and many likely rerelocate the LCD panel itself to have the ability to obtain at the inverter and rerelocate it from the bracket it is attached to at the bottom of the display. You"d recognize if it was an inverter that was going, bereason you"d be able to still check out what was being shown if you pointed a flash light at the display screen while it was dark. However before, they don"t tfinish to flicker as soon as the display screen is relocated or opened/closed. Some will flicker when they are going negative if you tap the bezel at the bottom of the display though.

It is more most likely that the concern is more expensive. Most human being open up and close their lappeak display screens from one edge of the lid, fairly than from the center... or evenly holding both corners. In time, opening from one edge puts a twist on the display and also over time, the LCD panel sepaprices from the PCB placed to the optimal edge of the screen. For some human being, this manifests in colored vertical lines on their display screens that will certainly either present up or also disappear as soon as push is put on one edge or one more.

Now... checking to watch if the wiring harness is loose or damaged is most definitely component of the diagnostic process. Why? Well, it costs you nothing but time, and also by doing so, you either find or remove it as the reason.

Tbelow is additionally a VERY tiny possibility that the problem is the CCFL (cold Cathode Fluorescent bulb) itself also. In one instance through an HP lapheight, the wire at the left side of the bulb had actually scorched off the bulb. The bulb itself would still function (as soon as the wire was re-attached) however otherwise obviously would not light. But aacquire, you can usage a flash light as soon as the laptop is on to check out if it is the bulb or inverter.

So... time to take acomponent your screen, and also view if it is the harness. If it is still linked soundly (at both ends), and tbelow is no damages at any of the locations wright here the harness bends, then you are looking at replacing your display.
