I had got the BK 08 a while back (more than a year) and was using it not that frequently. It has suddenly started misbehaving. It lights up once every 6-7 times of unfolding. No issues with charge it is fully charged.

I am able to open the internal parts safely and see for myself but couldn't understand the mechanism. When the keyboard is without back cover on its middle section, it lights up more frequently. If I disconnect one side of the keyboard by removing the flex connector it works on that side accurately but not the other side. I couldn't figure out what mechanism is sensing the unfolding. If it's the same sensor, how come it senses the folding accurately everytime but doesn't sense unfolding?

I am requesting either of following:

1. Help me troubleshoot?

3. Advise spares if any?

2. Help me figure out the mechanism of how the unfolding is sensed?

I would really appreciate your help. I am very sad, I liked it very much but haven't been able to make much use of it.
