I have checked all the pinouts of this display and proved them to be
common to most other displays acording to the T6963C datasheet.

I get nothing but random horizontal lines across the display, and
LCDinfo will show solid vertical lines where it is trying to display graphics
but too large for the screen.

I have checked and rechecked the wiring and as the lines seem to move around when the info changes I am suspecting that I am specifying
an incorrect size.

Does anyone know what size display this is as I have tried all software
I could find without much luck.

Do you have a datasheet for your display?

Check wiring again and again and again.

I have lost count on the number of times I have re-checked the wiring,
even leaving it to the next day didn't help.

I followed another thread from this forum
http://forum.lcdinfo.com/viewtopic.php?t=576&start=0&postdays=0&postorder=asc&highlight=

which looks to be the same as I have worked out.

I have noticed that although the lines across the display seem to be random, they apear to be the bottom most line of each character in text mode, and a Bitmap shows up as though lines are missing.

I am now thinking that the row generator chip T6A40 could be at fault.

Looks like it was a faulty display. Tried another and it works fine.

I have a small black bleed mark on the screen even with no power, if anyone knows how to fix this, let me know.

Thanks
