The following is from Alvie Rodgers at Hitachi:
If the Pink picture can be corrected by Initialization, the drive PWB must
be replaced. If this is the case, make sure there is the new style bottom
filter (lunchbox) replaced as well.
If the Pink picture is oval and not the entire screen, then the engine must
be replaced.
Overheated LCD color filter.
All this, of course, is on the web site under "Things you should know".

Jim McVey (becyn) has a link that he posted yesterday 11/28. If you
still have it you can click on it and it will take you to the Hitachi site
and the LCD pink picture check. If you can't get it that way I will try to
separate it from the training manual and send it to you. It is rather
extensive. I can type it out if nothing else works. LMK.
