Sometimes I swear I can beat my head against a wall at times...
A Simasima Mac is something most Techs dread and rather fixing it, just replace the motherboard. But there are a few brave souls like Uniserver and TechKnight that would find this a challenge to fix. Is it a stuck data line, a broken address line, the clock stopped? What ever, they have brought dead Macs back from the grave!
Since joining this community, I have been corresponding J EnglishSmith about acquiring a 1400cs to fix my dead 1400cs/133. It died years ago when I got a memory upgrade for it, put it in and the 1400cs went into Simasima mode. I took the memory upgrade out, and still - Simasima mode. So I thought this memory upgrade is faulty and had killed my 1400cs. With a working 1400cs and 1400cs parts I got from him, I swapped parts in and out of the machines and concluded - it must be a logic board failure, the damned memory module fried my logic board! Good thing is, the other RAM, CPU card, Hard drive and everything else works. All I would need is another logic board to fix my dead 1400cs. Meanwhile, I took my aggressions on the bad memory upgrade with a pair of hammers and a flight out of a 13 story window.
Got the money and the time, and got another 1400cs and a bottom 1/2 of a 1400 from J EnglishSmith (it arrived today!). Time to swap parts and get my 1400cs running! The nice thing about the 1400cs is that everything is modular and accessible with #0 or #1 Phillips Screw Driver, no more funny Torx bits! It took about a 1/2 to swap the logic board and put back together my 1400cs/133 within a 1/2 hour time of work.
Power up, "Bong!", It's Alive! But a second after screen lights up - Simasima Screen!!!
DAMN IT ALL!!!
I did not want to tell J EnglishSmith the Bad News of the logic board arriving DOA. Especially since he worked so hard to insure that it would survive shipping, which it did! So I decided to put the machines back together.
But then I decided for some oddball reason to swap the LCD Heads (the whole display assembly) with the good 1400cs with the dead one. Power On, "Bong!", Simasima Screen. Put the working LCD Head onto the dead Mac. Power On, "Bong!", intact screen with the "?" flashing inside of a floppy drive! So it wasn't the logic after all, but the LCD Display Panel.
I have not put the two machine back together but soon will. Now to fix this, priorities will change to getting a new LCD Panel. It could be the wiring harness that went bad but I wont deal with it, for me its better to try to get whole "new" display head and then sell the dead one since its OK and in one piece though there is some cracking at the usual area.
Lesson learned: test everything, and don't fault a part that are otherwise OK until proven faulty. This "repair" has taken 5 years to figure and one day to complete as I was looking for a cheap 1400cs logic board. Now I know it's not the logic board and will be saving up my pennies to get a display unit. I think J EnglishSmith might have one, I have to ask. But for now, time to switch parts to their right places.
