WHITE CORNERS IN LAPTOP SCREEN

[arnabgupta9]

 I have an HP NPTEBOOK AY-542TU. I have been using it for almost a year. It recently has started to show white glowing corners of the screen. Both the left top edge and bottom edge has these white corner.  Those are visible when the screen is dark. I am worried if it might become worse. The warrrenty is over. What should I do?

Backlight leakage is far from unusual in the corners of flat panel displays. As this web page (click) explains, there is really nothing you can do about it unless you are prepared to replace the display panel at your expense (which might simply swap one panel with backlight bleed for another one with similar or worse bleed), or you are prepared to experiment with adding light blocking material inside the panel - which is very much at your own risk!

The chances are that the bleed was always there; it is unusual but not unheard of for bleed to develop or worsen over time. If you had noticed it whilst you still had warranty coverage, it is perhaps doubtful whether HP would have authorised a warranty panel exchange for backlight bleed, especially on a budget laptop such as a Notebook 15, though it would not have hurt to have asked. Now that the warranty has expired, you are very unlikely to receive support for any further hardware issues. The consumer desire for inexpensive devices with thin and light displays leaves manufacturers having to compromise on performance and on what will be accepted as a fault justifying product repair or replacement.

Though it doesn't solve the underlying issue, it can minimise noticeable bleed if you turn the display brightness down, especially when you are in dark surroundings.

So far as what you should do now, I think the best approach is to try not to let it bother you - which will be hard, because you will naturally look for it now that you know it is there. I am certainly not aware of any steps you can take to limit the worsening of bleed if you are in the unfortunate position of having a screen with progressively worsening bleed. I would not pay to have the panel replaced unless you simply cannot live with the problem any longer and are happy to take the risk that the new panel will not necessarily be free from bleed.
