Sears LXI Projection TV with no picture

[NoStar]

This is a 60" CRT rear projection TV that powers on but with no picture. There are no menus or anything. The audio works, and I can tune thru channels by listening. Sometimes when I turn it on, there's a quick flash. I took the back panel off and found that the flash is coming from the inside of this composite square unit, that looks like a distribution box that supplies the 3 crt guns with the power from the single flyback. It lights up inside briefly and some smoke comes off of it. Since there is no picture at all, it seems like it has be something common to all 3 crts. and not the crt's themselves (I hope). Here is a link to some photos I took of the unit and surrounding areas:

I'm also trying to identify the parts from the flyback xformer forward. The thick red cable comes out of the flyback and goes into a thin black square box above it with a sanyo sticker on it. Then another red wire comes out of that and goes to a white box with 4 towers on it. That has a phillips sticker on it. I imagine one of the two is a rectifier.

The model # is PTV515-AH01

I pulled the part in question, its the HV Splitter/Focus combo block, and I found a site that has what appears to be a replacement, but at a *used* price of 189.00:

The one shown as 220482-14 appears identical to mine. So now my question is, can I get one new and/or cheaper? Also, is there a way to determine if this is all thats damaged?

It sounds identical to this post here, which is why im concerned about other parts. Also I believe it is also leaked coolant that damaged my block.
