I used to have an IC-756 which is famous for problems with its LED. Once 
upon a time the famous problem has hit my radio... The famous horisontal 
lines came up. The backlight has been put on MAX then. Having seen the 
lines, I have lowered the backlight to the level (60-70%), the lines 
disappear while the whole display remains perfectly readable.

It was good 5 years ago.

The radio has been sold to another guy who extemsively uses it every day and 
there is not a sign of problems neither with the display itself, nor the 
controlling circuit.

73,
