Dell Presision T7610 power supply

With no schematic available, start by replacing the most common to fail parts - the electrolytic capacitors on the board.  However, if you decide to do this, be sure you're well versed in repairing high voltage parts - there are very dangerous voltages exposed inside the power supply.

Sorry, this is Google translator.

The power supply unit only worked for 2 months and broke down.

The new power supply will be delivered for more than a month, all this time I can not work.

So I'm trying to fix it.

So it should be clear

Repair is engaged in my friend, he is a master, but he says without a scheme is difficult.

Condensers have already checked, they are normal.

We found the burned resistors, replaced. While everything is the same. We are looking for the reason further.

I could not find the PSU pinout to start the power supply without a computer.

If what you're looking for is a schematic, you won't find one for a power supply - if something has failed, the power supply needs to be replaced.

There's some information here, but in general, you're in for a black-box repair unless you find that someone has published what you're looking for - Dell doesn't publish that level of detail.
