I am very curious to see the results of this! Hope it works!Winner winner screen dinner!
It’s a PB 170 screen with a huge tunnel problem here. Corners begin to dark after a few seconds and in a two minutes nearly all of the screen is dark. According to major opinions in this thread, I will bake for three or four hours at 80-90ºC and see what happens. Also I put one silica bag in every corner after taking the picture. I’ll post the results.

I like this idea, if it turns out that it is moisture.How about putting the screen in a large enough food dehydrator instead of an oven?
or silica gelnext we should try the bucket of rice for a week
Thanks for posting your 'recipe' and the in-process pictures. I would like to try to replicate your results with a PB180 screen that is showing signs of the tunneling issue. It will take a bit to sort out which oven to use and the correct settings, so it may be a while before I report back, but its good to see progress here. Also glad that you and yours are safe.I kept it between 80 to 90ºC for about six hours twice. Temperature above the boiling point, to avoid expanding gases and I let it cool down for the whole night inside the oven. I didn’t open the door during the process to avoid abrupt thermal changes that could crack the screen.
I used a regular size oven, upper and lower heating. I think it’s better to use one of these rather than a smaller one, in order to keep a safer distance between the screen and the heating element. Don’t trust the oven’s thermostat, by the way. Buy a cooking thermometer, they’re cheap and more reliable.Thanks for posting your 'recipe' and the in-process pictures.

I kept four silica bags in the display assembly, I hope this will do the trick, at least for some time.How do you keep it from tunneling? My 170 has a problem were it has 3 lines going down on the far left of the lcd when on but it goes away when i put pressure on the side of the screen. Its not the lcd cable. Thats good everybodys safe.
