The first one is fine until I fill the screen with numbers and then various segments across the screen fade.

The second one shows a brief PR Error when I put in batteries, but it quickly fades to nothing.

Both machines were working the last time I used them (10 or so years ago), but one would dim the LCD slightly when I pressed a key.

Does anyone have any info or links on repairing these issues?

Off hand, it seems like a power supply issue, most likely caused by corrosion somewhere, but may be a faulty component inside. An internal inspection should find the corrosion or wiggling the board(s) to see if a connector is playing up.

If the main chip is faulty, I don't know how available they are and if they can be replaced.
