Hi,
I have a small number of monitors based on the above panel and am working through them. I have at least two with a single, burned-out diode. From what I can see it's something like DI428 or DII428 or DH428. Here's a picture of a working one.
Can anyone identify this please? Based on the number 428 it may be a shottky or a Zener according to Google. The device in question is D105.
ETA I can confirm that the number is definitely 428 (I took a video which revealed a better image), the DII appears to be a maker's mark. There's also a code 1G. Looking around...
