I couldn't manage to embed the pictures, so I have attached them. Also .jpeg files are not allowed! WTF! And apparently only tiny files are allowed! So, one per post. Sigh.

Your pictures are too big. Use a program such as "IrfanView". Resize images to 1920 x 1080. Save. Then you should be able to upload each pix in one post.
P.S. I prefer to upload high resolution images. Extremely low resolution images such as 1920 x 1080 are annoying when you want to zoom in on the detail (which is something I do all the time and assume that other people do as well). I would rather not have compression used at all, but uploads are limited to 1M per file so a full resolution image of 25M or so doesn't work. I should have done two per post, though.

Yeah. They need to be resized first. Or try something like www.imgur.com which should take care of resizing and give you (img) tags you can can copy and paste.

Huh? Resolution is only useful when the actual image supports it. That picture is nowhere near sharp enough for a 5269x3573 resolution to be useful...did you even look at it? It's blurry! You're just wasting bandwidth and server space and annoying people on slow connections...
I size my photos based on the actual level of detail in the original. Works much better.
Hello,

Best thing you can do is download the service manuals. They are invaluable and the troubleshooting steps for the power supply are very good. Failing that join the Tektronix's group on yahoo. That's where the Tek experts/enthusiasts hang out.

I had a issue with a power supply on my 2465B and if it wasn't for the help on the group never would have figured out the problem. Aged and out of spec opto-isolator. Note if you recapped there is a error on the schematic and likely one of the caps was inserted backwards, can't remember which though.
Here is the damage, apparent bad components and recapping of the A3 Inverter board for my 2465B CT scope.
