Rohan,
I got the latest LX90 in the same shipment. When I do auto alignment, the alignment stars are a couple of degrees out, but once aligned, the goto puts the object at the top right of the view; close enough for now. Sounds like Wayne's method of manual alignment is better. I have yet to correct the Lat/Long which I know is a little out and each time I have aligned I have had metal within a few metres of the scope which would effect it's north sensing. Maybe your LNT module is faulty. My scope was inaccurate out of the box, but I immediately found that Bintel had the wrong date entered and once corrected it performed OK. I had a bit of trouble with the red dot finder but once I got it working correctly I found it really useful. I haven't got anything else to compare with but I'm impressed with the optics so far. Sounds like you have some problems, given that the unit worked fine the first time. I also noticed in one of your other posts, a long DC power cord in the pic, you probably will have a substantial voltage drop over that cable and that could be causing your problems; I would recommend trying it on drycells in the supplied base compartments. If you get some duracells from an office supplies place you should be able to get them for under $1 each. (Meade claim 60 hours to a set but my estimate is more like 6 hours.) That will give you a stable power source for testing and at least eliminate one possibility. Don't fall in to the trap of measuring the voltage on the plug of your cord as this figure is meaningless unless under load. I would also try manual alignment as Wayne suggested, then if it's still faulty give Bintel a call.
