Thanks for the information. What you are describing sounds a bit more intense than what I'm willing to try at this time. An option I might consider in the future is to sell it as is and try and acquire one without any display problems. I understand that as time marches on, such an acquisition might be difficult but I guess that is a risk.
As I mentioned, I can live with it as is (at least for now).

That might just be a bad contact or a bad driver chip. The missing row troubles me more as it could signal a bad LCD glass. I have a T102 that has the same symptom and tracked it down to the glass. Interestingly the LCD glass is laid out symmetrically. You can take it out of the frame and rotate 180degrees and if the horizontal line is also moved you know you have a bad glass. Getting the LCD glass lined up correctly on the PCB when putting it all back together can be tricky though.

I attached a picture illustrating the problem. On the picture, you can see that the top of the 6th line has a horizontal roll of pixels out. It is most noticeable on the number, "5" where it took out the top of this number. The vertical column of dead pixels is on the column labeled, "Dist". It affects the first four lines of the display and you can see where the number, "9" is affected.

If the problem is a corroded connection to the LCD glass there is a 50/50 chance of fixing it and getting the glass lined back up properly. I have also seen a missing horizontal line be due to a bad LCD glass. The driver ICs can also fail and they have to be scrounged from other LCDs are they are an odd/smaller package that seems to be unique to the M100/T102.

The seller's definition of "mint" differed a bit from mine in that a horizontal row of pixels is out and there is a column of pixels that is out for the top 1/3 of the column. Do you fix these and if so, how much would it cost? The Y2K updated ROM sounds useful as well. Lloyd
