[ICOM] Request - dead 756 Pro series display wanted

[Ted Hay]

Believe the back light wasn't a problem with the original 756, the 
display developed vertical lines.

A bonus is that if the display's only problem is the backlight (even if the problem is in the cold cathode power supply - which accounts for more failures than the tube itself) you will receive the display back, hopefully better and brighter than before.  It's been a good while since I've seen the older original 756 (non-pro) but if I recall correctly, the display module "sandwich" from the original (non-Pro) backlight and diffuser system is quite similar in design, even though the LCD component is monochrome.  I'm offering this to the list in return for all the good Icom info the folks here have provided me over the years.
