Common BOE-Hydis IPS' problem?

[ziemeck]

I had to replace screen on my 2007-FHG due to malfunctioning screen. I have noticed that the problem is pretty common (horizontal lines appearing/disappearing depending on lid flexing):

screen 1
screen 2

Any ideas if this can be repaired? Note - it IS NOT the cable!

More than likely it has a few bad row drivers in the LCD. There are row driver tabs bonded to the glass and these can go bad. The fix is to replace the LCD...no repair.

Anything can be repaired.. it's just a question of costs.
http://www.moniserv.com/doc/panelrepair.html lists a type (ACF) which they can repair, but by simple inspection this is not the type of bonding required in laptop LCDs.

From http://www.hitachi-displays-eu.com/doc/ ... ethods.pdf i'd say the solution which is applied in laptop panels is TCP with heatseal.

These people claim to offer Heatseal recovery: http://www.febaelectronics.com/?title=l ... r&menuid=9 ... but as to the success rate i don't know. Cheap? Almost certainly not, but if you are a company relying on a specific display to function (for example in avionics) which is non-standard, it would be more than worth it.

If it is pressure-related, it is possible it was a problem in antenna cable routing after a repair. I have seen cases where rerouting cables fixes this problem, especially if the is the extra WWAN antenna

Nope, in my case the lines appear even at very light pressure - caused only by lid imperfections. If I took out the LCD off the lid, the image was flawless, if i only very lightly squeezed /rotatad the metal frame- the lines appeared; only at very special squeezes/rotations of lid the lines were gone - but such position was ALWAYS attainable.
