Kevin, specifically check soldering and continuity and look for shorts (with a meter) on the pins connecting the front panel to the main board. You want the pins that carry LCD lines D0-D3. I had the same problem and I had a short underneath the right angle connector between the pins for D0 and D3. The easiest way to look for the shorts is between the pins on the LCD display itself.? Those are pins 7,8,9&10 on the lcd unit. Measure with the front panel connected to the main board. If you find a short, remove the front panel from the main board and see if it¡¯s still there. If not, the problem is on the main board, most likely in the area of the connecting pins. Good luck

There's been talk of checking the display's data lines. The older
firmware only used 3 bits, where the new uses 4. So check for
shorts between the data lines.
Also check on the mother board, people have found issues there
too!
Good Luck!
