Screen Brightness Issues

February 27th, 2007, 01:33 Posted By: wraggster

Fanjita posted this news over at noobz

After using the downgrader, some people have had problems with their screen brightness. This article explains why, and what you can do about it.

The problem seems to occur only for recent TA-082 / TA-086 PSPs, that came originally with firmware 2.71 or later.

The problem is that Sony changed the display hardware in some of the recent PSPs, and the firmware needs to be aware of how to handle that.

This means that if you run a lower firmware than v2.71, then the display isn't given the right brightness signals. Where normally you would see a bright screen, and it would go dark after a while of not pressing any keys, now it is normally dark, and goes bright if you don't press anything for a couple of minutes.

The best fix is obviously to install a firmware that can control the display correctly. Fortunately the OE firmwares, e.g. 3.10 OE, will do this. The only drawback is that, when running homebrew in the 1.5 kernel mode, you will get the old screen behaviour. But you should be able to work around this by pressing the 'screen' button a few times.

It's also possible, for advanced users, to make a hybrid firmware that will use the later screenhandling code in the 1.50 kernel mode of OE.
