Hi everyone, i have a ps3 CECHL04 with a VER-001 board.
I'm searching for the boar service manual with schematics.
I can't find anything everywere (i just found for COK-002 board if someone is interested).
Can you help me to find this schematics?

Thank you very much.
 
afaik the service manuals were leaked only for models COK 00X and SEM 001, for the other models nothing official was ever found.
What's the problem with your console, maybe we can help.
 
My ps3 didn't start well.
I got the syscon were i had errors 1002, 2022 and 2124.
Than i replaced all 8 nec tokin from the board.
Now the ps3 start but i cant see nothing on both av and hdmi out.
Also the pad can't connect.
I tried to reset ps3 out by pressing the power botton but i still don't see anything.
I got again the syscon and i had again errors 1002 and 2124.
According to psdevwiki the problem for 1002 could be the rsx, the nec tokin or the nearby components of the power block.
I would like to understand if the nearby components of the power block are ok.
If they are ok, only rsx remain (perhaps reball).
Thank you.
 
There are only 3 leaked service manuals, for COK-001, COK-002, and SEM-001 (coincidentially, are the 3 PS3 fat motherboards with NAND flash)
The mention in wiki about posible candidates for the problem could be "the nearby components of the power block" is something generic, because that components are located in between the PSU and the tokins

There is also a leaked .pdf with some error codes (that seems to belong to COK-001), the problem with error codes 2024, 2124, and (never found) eventually 2224 is that doesnt appears in that document, it seems was added later for newer motherboard models, so we dont know well what they means, are actually labeled as "AV" because we know are a bit related with HDMI, DVE, and audio chips

The error 1002 seems to indicate something related with RSX power, but RSX shares some of his power lines with the HDMI and DVE chips, take a look at this schematic made by @RIP-Felix for a reference, there many voltages in RSX

And there are some descriptions of that voltages at bottom here

I tried to see the vlotage in standby on the nec tokin position (using a multimeter) but result 0 V.
All the voltage can be measured only when the ps3 is turned on (green led) right?
