Zebra stripes for LCD - help/advice wanted

[acadiel]

I have some TI CC-40 systems that seem to have bad Zebra stripes. Or at least, that’s what I figure. I can get parts of the LCD pixels that are missing by gently pressing down on the bezel. I’ve tried cleaning the stripes and LCD with alcohol - no dice. I think the stripes just might be warped. It’s a common issue with the system.

(The LCD has a bexel/frame on top of it with metal clasps in the back that are bent at a 90 degree angle to put pressure on the LCD and Zebra stripes to make contact).

I’ve never ordered new stripes before, so I need some help on figuring out what to get and where to get it. I lucked on getting the schematics for the CC-40 LCD as well as the specs for it - the whole engineering diagram. Attached it here, but it says nothing about the zebra strips that in need.

Can anyone help? I wonder now since we have the specs if we can get some replacement LCDs made too.

Thanks!

There is a guy in the trs80 model 100 mailing list that has ordered zebra stripes for M100. Maybe that is a good source for you too. Perhaps thr same company could supply some to meet your needs. Mailing list at bitchin100.com.

Just get some tape and fold it over a few times and throw the frame back on. How I fix alot of lcd's with this issue. The tiny bit of extra pressure seems to cure it.
