I guess you have already opened the machine and reseated all ribbon cables? Make sure you are well grounded - there are many sensitive CMOS parts in the display module. You might also want to read through the Service Manual to see where else a bad connection could be located in the display module (hoping that it is only a contact problem). I don't know whether there is a flexprint/rubber pressure pad combo involved, maybe immediately at the display - these are well known for losing contact pressure over the years (a typical problem for the HP 48 calculator family).
