McD replaced my ram and it changed nothing then changed it back since it was the apple branded ram for me, which as a 128 is kinda cool for me.  I have 2 working 128's but both upg…

Too bad. I have a Simasima 1400, and it turns out that the 1400 is OK, its the LCD Screen that is Simasima. I would love to fix that one day. 

I looked at your pics (it did not load the first time I posted but that is on my end). Sad news. Looking at the bottom board, I saw several of the solder joints from the capacitor…

i found some trace on the back side of board. that looks like someone had tryed to resoldering or replace ram. but every ram has thext "4264" with apple mark. so i thought someo…

video artifacts and sadmac code is all bad ram.   who swapped your ram chips for no charge grandpa?

Just FYI my ram was swapped with new chips and no change. If you have video artifacts with the error code another chip may be at fault. I have yet to figure it out. Now that I a…

IT needs a re-ram. i offer this service... its a big nasty job.    i did 2 over the weekend.

PB 1400c use Sharp LQ1142 11.3" screen. You can find some alone on the bay, but not cheap. Don't know in what other machine it's been used...

Not possible sorry - the connectors, timings, etc are all different across most LCDs.  Do you have a part no for the LCD, it might glean more info if it was also used say in a Tosh…

Charge light doesn't seem to work but it does seem to be charging.

Maybe There is a way for adapting an easier to find part, since this laptop is hard to find parts. Anyone have tried?

Probably unlikely... anyone have a 3400c logic board out that they'd be willing to take a picture of?  Specifically the underside right below the power adapter port and next to the…

Very good! Now all you need to do is retrobright the space bar, and you can get it looking even better! c

Any ideas when the WIKI is fixed? Maybe a repair of the database necessary?  Need any help?

Do you guys have a link for a site with a junk one? Could not find on eBay and we love macs won't ship to Brazil
