If I try to adjust this with HSIZ and HPOS, it moves to the right but it looks like it's squished on the right side.
I may be replying in the false belief that the 30HS420 has the same (or very similar) service menu as my 34XBR960. If that's not the case please disregard the following comments.
With the XBR960 there are TWO sets of adjustments for basic horizontal and vertical geometry tweaking: one for the "background raster", and a second for the "foreground image overlay". Each of these two sets of adjustments has, itself, two sets of tweaks... one set for the horizontal dimension and one set for the vertical dimension.
All told, "background" adjustments are for horizontal and vertical size and position (that's four service menu items), and similarly "foreground" adjustments are also for horizontal and vertical size and position (that's four more separate service menu items). Eight service menu items in total, four for horizontal and four for vertical.
You've only mentioned your 30HS420 adjustments to HSIZ and HPOS, but nothing else (at least for horizontal). That would suggest you've adjusted the "background raster" in the horizontal dimension but not the "foreground image overlay" in the horizontal dimension... assuming that there is the second set of service menu items on your set which I'm alluding to. If that's the case, perhaps working on the two "foreground" tweaks as well as the two "background" tweaks you've already addressed might accomplish what you're looking for.
You may have done much research already, but if you read this post
and all of the further posts that are referenced by it, you will find instructions on adjusting BOTH SETS OF TWEAKS, to properly reposition and resize both the vertical and horizontal dimensions for both background and foreground. Again, my posts deal with the XBR960 so my apologies if that discussion does not apply to the HS420.
If the service menus are similar then if you follow the recipe described by my series of posts you will get into the 2170D-1 service menu group to adjust VPOS and VSIZ (vertical position and vertical size of the background raster), the 2170D-2 group to adjust HPOS and HSIZ (horizontal position and horizontal size of the "background raster"), and the MID3 group to adjust VDHP, VDHS, VDVE, and VDVS (horizontal position, horizontal size, vertical position, and vertical size, respectively) of the "foreground image". MID3 is used to manipulate the "foreground image" on top of the "background raster" for the 720p/1080i inputs... at least on the XBR960.
If MID3 isn't present, or doesn't work, you might look at MID1. This group (which I believe has DDHP, DDHS, DDVE and DDVS instead) was present on some lower-end or older 34XBR, XS and HS models so MID1 might be what they used on the 30HS420.
Hope this is helpful, and not totally irrelevant for the 30HS420.
