After blowing up my 20*4 display, don't ask how but there where impressive blue sparks, and it's a miricle I didn't fry my PC

I'm now using my old 16*4 display. Which works perfectly with Mike Lynch's plugin. However with ever other plugin it displays the text 4 blocks to the right, it also does this with LCD print and every bit of software I've written. Any ideas what's going on?

I've spent about 3 hours trying to get it to work with no joy.
