Hi,
I received a Chaintech CT-7NJL4 for initially free. State, broken.
Without powering it on, there is a 2 and respectively 4 Ohm short to ground on both +3,3V and +5V lines.
There's also a 6 Ohm short between these lines (2+4=6)
This seems way too low. Too bad I don't have a thermal camera.
Does anyone have a pinout for the chipsets so I could check whether they use what voltages?
These *seem* shorted at the same point to ground. Maybe an IC? or two fets (one on each line)? Hope not the chipset..
Any ideas?
Best regards,
Martin
