LG B9 Bright Flash

[bongio]

I started experiencing random bright green/blue flashes on my 18months old LG B9 (see video).

The frequency is around a flash every 2 minutes.

This happens watching local content (for example using Amazon Prime), so it shouldn't be related to bad cables/connections.

What could be the cause?

Thank you!

Seems most likely a main board issue for that sort of fault.

I have this same problem with a B8 except my color is white. Did you ever figure this out?
