I've placed the complete color display (CRT/Color LCD Shutter/Driver
Electronics) from my defunct Tektronix TDS-544A on eBay (item
7534375672). I believe this display will also work in the TDS-524A,
TDS-6xx and TDS-7xx color 'scopes. Very low usage, excellent condition.

Here's a link to the auction: http://tinyurl.com/9sx2r
