I replaced the LCD screen on the DSP mid unit today as it had suffered the usual loss of pixels. All went well and I now have a clear display,


I was unable to identify this before due to no display as it has never worked properly. Any ideas what I could try or has someone come across this?
To set the clock took me ages as the only button that worked to change the time was the minute + rocker button. Sore finger now as it was 1hr fast..
