This is from Sony's commercial line of monitors from a few years ago, panel made by Fujitsu/Hitachi.
This one tries to start three times and then goes to flashing the LED sequence 6. This is listed as a PDP error, but can mean other failures as well. Apparently, the X-SUS and Y-SUS board were originally sold as part of the panel, but are now available as discrete parts. I get all of the voltages listed coming up ok except the Ve and Vq voltages at test points on the DC-DC board. The chart on this board lists them as +18v but they go negative by more than 100v. All ground points are at the same potential on this and related boards. Sony tech says that these are returns from the X-SUS board, but there is little info on either the SUS boards or the DC-DC board in the manual. Looks like the X-SUS board is bad, but I'd like more info.
Anyone familiar with these or perhaps with something similar from Fujitsu or Hitachi?
