My cannon printer PIXMA MG5320 was off one day because a surge in the house flipped. it wouldn't turn on at all no sign of power..
Pretty much i thought it was a goner and not fixable so i just sat it somewhere till i get time to fully take it apart.
Today i figured i see whats up with it, than i notice the power supply clips right out instead of being inside the printer somewhere. Pretty nice feature right there.
I took the psu plastic case apart and from looking at it i see no problems.
So i get my mutimeter to start checking the fuses which i see none at all. but after googleing some stuff of each thing on the board... yea im kinda newb with this stuff but i do get by cause i fixed 2 tvs already
But i found out it has 3 of these https://www.google.com/search?q=re22...2.5%20a%20250v which are fuses. So i checked each one with the beep function and they all get a beep and i check the Resistance and they all go to 0 asoon as i put the probes on them. But they do go to 0.2 than 0.1 than back to 0 than they will do the same. i herd it needs to be always 0. But than again im not using a high end meter.
So i checked a few other things i circle the 2 things i checked and i get no beep nor any resistance at all from the 2 which i think might be bad?
They look like a resister but also looks like a ceramic cap too. like i said im new lol
Pretty much it would be great to get the printer working again cause it was a good printer. Now they do have psus on ebay but they want like 30+ for them and if i can fix this psu myself that would be great.
Should i be getting some reading on those blue resister cap thingys? cause like i said i get nothing. I even tested the other blue one in the middle of them and that gives a beep and a Resistance of 0.2-0.4.
They also don't have a reading mark on them..
heres better pics i found on the net my pics was blurry but looks the same as these pics.

I just tested it plugged in the printer and ac powered threw it. and tested these points. yellow is 124.125v coming threw. red is at the connector were the printer plugs into it. here's the weird thing.. i get 4v to 6v at the connector but if i hold one probe black ground in my hand and the red on one of the connectors i get 14 to 15v, than if i touch the metal surge breaker while doing the same it gets too the rated printer voltage 33v. whats going on? it seems to be getting power threw the board so yea im confused.
