Hello,
I changed the PIA under the battery holder on Doctor Dude today and switch out the U25 for NVram. When I turn it on now I'm getting garbled characters on the left side display. See picture. If I press on the u41 chip or basically massage the chip, then I get what appears to be u41 pia failure, but then it also switched to Credits 6 after that. If I stop touching the chip it appears to go back to the garbled code like in the picture.
What would be the most likely cause?
The person who did it for me has been doing this kind of work for 40 years so I'm thinking the chip is bad?
Please help.
Thanks!
I didn't find the right solution from the Internet.
