Beocenter 1 with Suspicious Display and IR Board (PCB58)

[Peter Gallo]

Hi all. I am new to the community. I have a Beocenter 1 that I absolutely love but it suddenly stopped powering on from standby recently. I am highly suspicious that the problem actually has to do with the IR sensor board and not any kind of power issue for the tube. I believe this TV can only be operated via IR remote so I want to make 100% sure that the IR system is working properly before I start to look at other components for the culprit. I actually got the set to power on last night when I was fiddling with the IR board (identified as PCB58) but I can’t seem to reproduce how I got it to power up from standby. The little metal shield at the bottom with three holes in my picture is the IR receiver. I tested the resistor in the top left and it seems to be good. I also tested with a different 16-pin ribbon cable and that doesn’t appear to be the problem either.
Does anyone have any ideas for how to troubleshoot or test this PCB for functionality? I can’t seem to find a replacement PCB58 for sale. I have some electronics/soldering/repair experience but have no idea where to even begin with this one.

Thank you!
