Hi Pilatomic, In my experience Beo4 screens do fail, but replacement is actually quite straightforward because connection to the PCB is via a little rubber ‘contact strip’ – a replacement strip is provided with the new screen.
Can you describe me how the screen fails ?
I think there is a good chance the screen are actually fine, just not making proper contact.
The “contact strip” is called a zebra strip, it is commonly used for connecting LCD displays, but the drawback is you now have to keep it under mechanical pressure to ensure a proper electrical connection.
Failure to maintain the correct mechanical pressure is, as far as I know, the most common failure mode for those kind of displays.
