I am seeing light bleeding from all 4 corners of the LCD through the black front plate. It is more noticeable on the top right when in the inverse landscape position.

What can be done to block this light that is acceptable to Cytech ?

I would make sure the black tape is securely stuck to the LED side of the LCD panel - you have to remove the LCD panel to stick it properly to the underside. With the corners that have small gaps I would put a small dab of black silicone sealer just to cover it.

If all else fails I would put insulation tape on the underside of the bezel with a small piece open to allow for the IR receiver to have access to the 'outside world'

We dont see any light leakage from 4 corners. There should not be any such leakage
Do you have a photograph of this?

Does  anyone else using KT03  see the problem of "Light Bleeding from all 4  Corners of Display". If so please give details or a phtograph so the matter can be investigated. t should not be necessary for customers to add any tapes anywhere as there should be no light leakage

Mine bleeds only from one corner and is only visible at a certain angle. It's not a huge problem for me.

Thanks, Ingo, we can see it now if we look really carefully. Some people may find it a hiuge problem. Anyway we will see if that can be totally blocked in future
