Hi there, there is plenty of posts on here about them that tell you the same: they work perfectly fine to revive these old machines. I still install a couple of them on a weekly basis.
You loose external video. Brightness control works with the newer versions of the Tiresias. The boards now have a little PWM output for the LP8550; you run a wire for it. Another wire taps into the brightness keys-output on the keyboard-controller. This gives you brightness-control (albeit without the on-screen brightness indicator).
If you do a PRAM reset, the Mac needs to be turned off first, after that the BIOS is overwritten again and you can boot normally.
what else do you need to know?
captainmac thank you. I only came across this product recently and after watching loads of videos, hearing most repairers will not entertain this problem on the older machines, I was ready to tell my customer no. There are loads of videos on the fitting of these, but no real "trustworthy" reviews. Just wanted to know if this is a worthwhile repair and the overall outcome, i.e. effectiveness and longevity of the repair. I am more than capable of fitting it. don't want the customer coming back after a short while complaining that its not workinhg ( the repair carried out not anything else)
No problem.
I'd stock up on a couple, they're quick repairs and you can charge decent money for them.
Haven't had much returns, other than a couple where someone managed to damage my jumperwires for the backlight.
