I used the instructions created by Han to open the 48sx so that I could fix a non-working keyboard row.
I used a thin piece of rubber between the existing keyboard rubber strip and the keyboard connector as a shim.
My thoughts were that this would help provide the missing contact for the keyboard row.
I accidently disturbed the lower rubber 'zebra strip?' that provides contact for the LCD.
The unit is back together (right side does not snap back well enough).
It does not power on unless I press down on the right side of the bezel below the LCD.
And even then, the LCD is missing many columns after powering on.
1. What is the proper way to clean and reinsert the rubber strip for the LCD.
2. Is there a better way to provide 'gap reduction' for the keyboard contact than what I did?
A whole new rubber piece, or can it be shimmed in the manner in which I attempted.
3. What is causing the power-on problem?
4. What would cause the right side to not snap back together as well as the left?
I know this side was more difficult to pry apart.
Obviously, I am open to suggestions and criticism. The unit was working fine except the keyboard row not working prior to my repair attempt. The unit is at home at the moment.
