Corrupted characters on bars

[anonymous]

After a couple of hours of running, my screen shows corrupted characters. I have set the timings to give more time to the LCD but it has no effect.

Which version?
Can you post some debug output?
Are you sure this is not hardware related? Its possible to run another LCD tool on this hardware and test it?

Cheers michu

This is not my hardware's problem, I'm sure. I used the display with LCDHype before connected to a linux server with lcd4linux. I've tried with 2 PC-s, same problem. Corrupted or displaced characters after a while. I've checked the LCD's datasheet for the timings. Bigger timing values has no effect. And this problem is appeared only on bars.

Problem solved. I've set timings to a very big (!) value and it worked.
