Hi. My digital display sometimes plays up. I mean that it goes blank with just horizontal lines only and just noticed that the analogue fuel display is inoperative-I mean its on permanently at mimimum. can anyone help me please?

No ideal of the 928 dash but it maybe a bad connection, try unplugging and plugging the dash connections.

But this maybe in the module itself.

Often the supply to any digital LCD of that vintage is via a small rubber strip with carbon embedded connections onto gold pads on the PCB and LCD. You could try disassembling the entire unit and cleaning any connections but that would be a big job (had a very similar fault on a 1990 Blaupunkt CD player and cleaning it fixed the problem).
 
Hi JB :)

If you still have problems , let me know and I will message you Adrian Clarkes email addy (our PCGB 928 Tech advisor)

All the best Brett :)
