hi there

i have a code 25 which i really like. I dont play a great deal but of late i've noticed some stange behaviour from it;

1/The Lcd display flickers eratically between values and preset names when playing. Sometimes the display just goes blank, but luminated.

2/On occasions the whole sound fluctuates and sometimes even a complete loss of volume after a short while playing. The only way to get it back is to turn the amp on and off repeatedly.

3/Red edit light is almost always on and flickering .

I have tried to reset it but doesnt seem to allow me to do that -  the screen goes blank.

Its still under warranty  (just) but the shop i bought it from (Rockbotton Croydon) is closed due to the Covid.

Any ideas please
