Sad Mac icon error code problem need help

[GetTaDaChopa]

Im a bit stuck on this code, I've already looked at online but still cannot pin point what it means exactly:

SADFACE

00000005

00008000

any idea? I've washed the board (although maybe not well enough) and its a lot cleaner and removed most of the junk that was on there. Put it back in and still same code.

any help will give me a happy mac face, thank you.

Well this is a bit vague. your lacking some information here, as to WHAT machine it is? And if this code is occuring before disk access, or after? 

 

[GetTaDaChopa]

Sorry just assumed these error codes have the same meaning. Macintosh Classic. boots up with no chime. and shows this code straight away. I can disconnect the HDD and its the same thing. 

 

[techknight]

probably needs recapped. 

And no they do not, they vary by model. 

 

[GetTaDaChopa]

Anyone know what the codes actually mean?

 

[techknight]

There is information on how to decode sadmacs. But its moot until the logic board is recapped, and the AB.

TK is right, no point in troubleshooting codes until the basics are done. Otherwise, you solve one sadmac, you get a different one after that, and one after that, etc...ad nauseam

I've recaped it today same error code. If anyone can decode the error it would be highly appreciated.

Code 5 = bad RAM. either on-board, or external card. If on board chances are the cap goo rotted a trace or two going to the RAM ICs. 

 

[GetTaDaChopa]

what about the second line of error code? I've tried baking the logic board in the oven as well, same error. seems to have done a good job on reflowing it but same error. 

 

[techknight]

address location. But its not important until you either remove the RAM and use the external card only, or fix the trace. Its possible one of the RAM ICs is simply bad as well. 

 

[GetTaDaChopa]

so it should wotk with all the ics removed with just the card? i removed all the ram chips from the logic board and pluged the external card in and its a sad mac with a different error obviously saying the ram is missing? can i use any chips to replace the inboard ones? the knboard ones are mitsubishi? can take the ram fronthe external chips and solder them in to the logic board?

I remember there was an experiment with removing the RAM in another thread. Whether it works on a classic or not, I cant remember.
