View Full Version : TRS-80 Displays Garbled Characters

February 6th, 2005, 09:51 AM
I have two TRS-80 Model 100s and one of them powers up to a garbled display. I've tried the reset button to no avail. Is this unit worthless? Is it worth including in my package to sell on eBay (even for parts)?

It probably is making a bad connection at the ribbon cable from the mainboard to the LCD, due to corrosion or whatever. (I've seen this before, and it wasn't a serious problem). If you feel brave, open it up and unplug/plug the cable (both ends) a few times and see if that helps. Even if you can't get it working, it still has value as a parts machine, especially if the case looks good, etc.
I just picked up a Sharp PC-1500 the other day that has the same problem, but I haven't had a chance to do anything with it yet. I'll get to that today, and report back here afterwards.
