OP77A Dispaly goes Blank - reg

Sreeram Posts: 53 Rating: (0)	Dear All, I have got an OP77A display unit (6AV66410BA110AX1). After wokring for about 2 months in the machine, suddenly, the dispaly has gone blank. We opened the unit and found that, there are no burnt symptoms and when powered up, the background illumination is very well present but the text is not getting displayed at all. I suspect, there could be some kind of a OS corruption in this case. Can you please throw more light on the probable reasons of this issue as it is required very urgently? Await your reqply at the earliest. Thanks & Regards Sree
