My powerbook 170 and the tunnel vision
Posted by: Rikintosh on 2018-12-08 06:24:52
I'm going to try to dehumidify the screen of my powerbook with a new method. I have seen many people trying to bake the screen in the oven, but in my opinion, that will not work, because evaporation must occur in a slow process, the key is not high temperature, but time. I think it's necessary to let it evaporate for a long time, at a reasonable temperature.

So I'll leave my screen under this halogen lamp for several hours, and I'll post the results here. If I do not get satisfactory results, I will try to leave DAYS under the lamp, and I will also try with some kind of silica

Sorry for my bad english. I'm from Brazil.

You realize that even if you can get the water out, its only a matter of time until it fails again, right? It's an inherent manufacturing defect. It can't be corrected.

Nothing to lose anyway, i have a Powerbook 170 with this problem (had another one not having it, but the screen seemed different, with a orange hue) 

Keeping the Powerbook in a warmer place apparently improved the issue, but didn't solved it.

Maybe someone can enlist the help of a Chinese factory and reproduce compatible panels using more modern construction methods which aren't susceptible to this tunnel vision problem?

Then we can get neat things like LED back lighting and such right out of the box.

Does anyone make a 6-bit grayscale panel that size any longer that would be compatible?

IIRC the panel itself is still sold, don't remember but can be found online.

Wasn't cheap...
