Am running an original IBM AT with Hercules board.  On power up the
screen is filled with 80 vertical thin lines, each of which passes throughthe
centre of any letter/number typed onthe screen.  

When I load any of my applications software such as Excel/Word the 
screen clears and acts normally.  Some applications software, for example 
PCTOOLS which uses just the test mode also shows the #@!!& s.

My guess is that I have a faulty chip on the video board: My questions are:

	(1) Does this diagnosis sound right?
	(2) How can I tell which chip is damaged?
	(3) Is it worth the effort to fix?

	Thanks for any help.
