Guys
I'm trying to repair a power supply for an old(er) 22" Venturer TV/monitor by Venturer Electronics Inc. out of Ontario. Model: PLV 16198 Manuf. date: October '07.
I've been unable to find a schematic for this thing but I 'think' it's a big box electronics/retailer offering like BestBuy or Walphart.
I'm brandy new to power supply testing so any advice greatly appreciated. I'm still also learning how to test components; FETS,bridge rectifiers, etc. I'm most proficient at testing diodes, caps, resistors, and transistors. I have ac mains up to the dc conversion section but no dc out. All the caps test OK with my Fluke 233 and an ESR meter and none are leaking/bloated.
Methinks I can't see the treefor the forest and am over thinking this tho. lol
I also could use a little enlightenment on how to test X/Y capacitors. There are a couple/three in the ac section but they were OL and no ESR.
Thanks guys!

I hadn't thought to even look anywhere downstream. (One of the dangers of learning from YouTube vids!!) I should at least get +5v on one pin thought right? PSon would come from farther downstream but would still have to come back to the tap at the SMPS I'm thinking. Unless I didn't catch neg from an isolated part of the circuit???
