Dashboard Info Display Not Problem

[Oakey]

The dash info display on my 59 plate Galaxy is playing up, working intermittently and not always displaying all the info i.e. mileage, temp, radio, station, fuel left etc. The pixels flicker across the screen or sometimes don't appear at all. I have been quoted 'between £150 to £250' to diagnose and repair by a company in Greenwich who want me to send the unit to them and they will repair. Not great reviews of them tbh and I imagine I will be charged £250 exactly.....

Has any one else had this problem and solved it, or anyone recommend a repairer so I have some degree of trust of who I'm using?

Thanks
