Re: Hitachi 42EDT41 42 in. HDTV-Ready Plasma
The Tech you had come out could be dead-on from what you've described... It could also be a bad connector. I've attached a couple of photos here to my explanation. One is a picture of what I am guessing you see on your screen when you power it up. If correct, you could possibly take a look at a line connector between the joint and formatter power board yourself and see if any of this is damaged.
To answer question more pointedly, (1) There are more than three boards inside, actually nine major board modules to be exact. (2) The Y SUS board, Hitachi p/n#TS05679, without going into great detail, determines the image position on the screen. (3) Cost - - Tritronics has this board at a list price of $436.22 and they are not as easy as they might appear to a layman to change...

Sounds like COF [Chip On Film] fault. Contact any service technician. To get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Line, faults & possible causes to LCD & Plasma screens are given with illustrations. You can get an idea about the fault to an extent.
The Y sustain board is not your problem because you have a picture. The problem is most likely the controller board and or the XR or XL board. It would be helpful for us if you post a photo of the symptom. Good luck
