A beginner's beginner...

Bah... well, that didn't work. I replaced 2 of the caps with new ones from Fry's just to see if that was the issue. Still not working.

I was very optimistic, too.

Hmm..

Now you want to identify the 8 pin SOIC, it's the SMPS controller so get the datasheet online and check it for Typical Applications where often you can find very close examples used in actual products.
When found give us a link so we can follow along and help if needed.

This looks like it's a flyback converter (Single input transistor)  In which case, the startup resistor is a prime candidate for going o/c or high value.  Usual clue is that without the small current this draws, the reservoir cap (big electrolytic center of board, mind your fingers as it can have 350v on it) will remain charged for a long time after power is removed.

Likely it's one of the larger resistors stood on end, R3 or its sleeved neighbour.  Will have a value somewhere between 47k and 1M. You can't measure it in circuit.

The other larger resistor, R17, 0.47 ohm,  is likely for current sensing. It's also quite common for resistors of this type to 'dry joint' so  check the soldering.

Some of the larger connection pins near D11 and L2 on the underside (possibly the transformer) also look a bit dry-jointish.

You can buy high quality capacitors in small quantity from places like Mouser. You want to match the microfarad, voltage and 105 deg ratings. If you select low ESR as a selection you'll end up with only a couple of choices. From google "mouser 10 microfarad 50v low esr radial" (radial = leads at one end) gets you to a chart and Panasonic EEU-FR1H100B is one that they stock and costs $0.33/each. You might want to add solder and other items needed for PCB work that you might not have for general repair work. A 60-40 solder in small dia. with rosin flux (never acid!), PCB flux to help solder in the new components, maybe a low wattage soldering iron and an assortment of tweezers and board cleaning gear and place an order. Also see if the fuse does reset or also needs to be replaced and add a new one to your shopping list.

Ok, I tested R3 and the sleeved resistor and they both checked out OK.

Then I took out R17 and got this. I did the resistor chart and this should be a 47 ohm resistor +/-5%



I cycled through the Range button and the only thing that shows anything is regular ohms. M and K shows 0000



I'm thinking this is a bad resistor?

[odessa]

Thats 0.47 ohm, so your meters good, and so is the resistor

[Pcmaker]

I'll put it back then. The BM235 can't show the next digit after 4?

Also, I'm not giving up just yet. One thing I haven't checked is the transformer. I only checked the mains coming in at 120v.
