Hello, yes your dump is fine (working).

I have 9v on the connector instead of 12v. Psu is tested ok. On one case the standy led lit red,(new 25q40 with another dump) in other cases there is no standby. Already replace 24c256 just to make sure. Should i give it a try to the emmc? I have a dump for this chassis.

It will not work with someone else's dump 25q40, do you still have your native dump? And bring back your native dump eeprom 24c256 (if you saved it). And what was the original problem?

Original problem was 9v instead of 13v on the connector of mainboard. When disconnecting psu from mainboard the leds lit up. I posted my dump yesterday here https://www.badcaps.net/forum/showpo...&postcount=100

I kept the original untouched and I worked with spare dumps. With another 25Q40, on 2 times, I disconnected the cable between psu and mainboard, removed the 220v and then plugged back the cable between psu and mainboard and then put the 220v back on. 13V was stable, standby lit but it couldnt start up becouse the dump was not native. I tried to replicate it again this procedure with a native dump but I was unsuccesful.

A strange malfunction, and no one has repaired it before you, maybe someone else's dump was already in it. If you flash eMMC, then you need to flash the whole kit (spi, eeprom, emmc).

If the problem is in the firmware, then you need to restore the native dump, and if you do not save the native dump and write down someone else's, then there is a high probability that you will have to look for a working motherboard.
