Please help diagnose my Ti - kullboys - 01-31-2019
Hi everybody. I picked up a TI-99/4A at a garage sale and was looking forward to playing around with it. Unfortunately, it looks as though it has a few problems. the TI splash screen comes up but the text is garbled.
Ive attached a photo of the screen. Any ideas? not afraid to break out the soldering iron

I don't see the attachment....
Does it work other than the display issue? I'm not an expert but I've seen a couple threads on other forums about the video RAM chips going bad and that seems to typically result in a working console but corrupt display.
