Help, I Can’t figure out Sad Mac code on my new 128…. :(

[Slammbone1986]

Found a very nice week 29 128 today on marketplace here in Atlanta. She told me it wouldn’t turn on. Of course, it does but the only code I’m getting code is “041CE0”. I’ve been trying to use the the website to decipher it and the only thing I think I can come up either is data bit 12 location G9.
Is this correct and if so is there any more to the “CE0” part of the code?? Ugh I’ve never been good at figuring these codes out. Anyway, any help would be much appreciated.
Thanks

Yes, G9 is a good start, probably first step.

Cool I’ll give it a shot and see what happens. Thanks!

 

[Slammbone1986]

Any idea which chips the “CE0” equals out to be??

Never seen before, but removing and replacing G9 will probably change the code and give some clues.

Updated :

If I understand it, 1CE0 is 0001110011100000 so you're reporting errors with data bits ... 5, 6, 7, 10, 11, and 12??
Someone check my working, did I get get it backwards because of MSB / LSB?

His G9 looks like it is working

Whoops , edited because I can't count

Just installed a chip in G9 and new code is 040CE0. So I fixed the “1” now to figure out the rest. Thanks for all y’all’s help, I’m going to try and make heads or tails or the previous chart.

Try piggybacking chips, don’t work everytime, but can save you time and money.

Not a great thing to do if one chip is stuck at one logic level and the other is trying to pull it to the other.

Surely try replacing chips corresponding to 5, 6, 7, 10 and 11 like the error code says?

Although I'm getting strong shadowban vibes.

 

[Slammbone1986]

yeah I’m going to throw in the rest this evening and hopefully I’ll have some good news later on.

Wanted to say thanks for the help with deciding my ram. Replaced all and shes back to life! Thank you!!

Well done! Were they Micron RAM chips by any chance?

They were Samsung KM4164A-15
