Hi.
Really, if you remove the connector strip, the bonding substance is removed, even the electrical cables will be broken. They are so delicate
I have this experience, and it's impossible to rebond the ancient connector band.
The main question is: Where to adquire a new connector band?.
Thx
Hello, is there any information which display is used? I would need to change it, but don't find anywhere spare parts... Thx
