T20 flickering screen when using AC adapter.

[Reo51St]

When using AC adapter screen flickers. Disconnect AC and it stops instantly.

Have tried other AC adapters and it does the same thing.

Any suggestions. Thanks in advance.

Just a little update.

When battery is removed flicker stops.

Tried other battery and it does the same thing.

When battery is charging it flickers.
