![]() Hello everybody
I'm looking for the electronic schematic of this NAS. In the motherboard I see the codes E230435 JH M3 94V-0 tm1210 and also tm-j1800 other diagrams of the same brand could also fit, for example F2-221 or others, as in the attached photo. Maybe it would be useful to know the name of the manufacturer. When I turn on the NAS, I see the LEDs on the front panel light up, but there is no power to the hd. the first two mosfets close to the power connector start conducting correctly, the next 4 mosfets do not receive power due to the absence of the command from the gate of the first mosfet. no power supply (it seems due to a short circuit in the central area of the motherboard). I would be very grateful to anyone who can help me by getting me the schematic in pdf format. :O) |

![]() I have F2-221. These boards are made by https://www.gifaipc.com/, might be worth sending them a letter if someone can draft one in Mandarin.
Out of curiosity, is there a chance you can dump its BIOS? As an experiment, I wonder it this would allow to revive the dead 221. |
