I'm troubleshooting the YSUS from a 60PV250 which had a open fuse FS104.
I replaced the fuse and its open again so I started testing all the transistors and diodes on the heat sinks didn't find anything out of order there.
Tested all the diodes on the bottom of the board and found D417 which shows a voltage drop of 103 in both directions.
The marking on the diode is 83 and then 19 right below that. I can't seem to find any info in this diode. Anyone that can help with identifying this part I'd greatly appreciate it.
