Pixels leaking?

Post by michaelzinn »

Yesterday morning, I found some weird black dots on my calculator's display. It looks like the pixels are leaking (It's definitely on the pixel layer, not on top of the glass). What is going on here?

Visually, it looks similar to the low-temperature, low-pressure display artifacts previously reported. Luckily these are fixable — if this is in fact the problem affecting your unit.

By chance, has your calculator been exposed to low ambient temperatures and/or low atmospheric pressures?

No, I keep the calculator on my desk, neither temperature nor pressure should change here.

On the other hand, the dots do look like the ones in the other thread. I'll try baking my calculator tomorrow.

I baked the board without the battery face down in a plate in the oven at 75 degrees for 5 hours, which fixed the problem. Thanks!
