Hi all,
I've got an H3000 on my workbench with no screen action.
There's some power to the board, but while probing around I've found a component that isn't doing what I'd expect.
The component in question is a SR3030 Schottky Rectifier, which is receiving an AC input of 7V to each of the input pins, but only giving an output of 0.5V DC.
I have no schematic so I'm blind-probing, and I've never come across a Schottky before but I have doubts that we have need for a 0.5V rail inside this thing, which makes me think that this component (or the transformer that's feeding it) is at fault.
Does anyone have any ideas, any info of what a schottky actually does, or a schematic of an H3000 that they wouldn't mind sending me a copy of?
Thanks in advance,
Phil
