Hmm okay, so there is nothing changed.
You still have a death box, with only the two network leds on.

Based that you have replaced the four big caps.
That you have all the main voltage on the P5 pins.

The main ohm values on the P5 pins are also fine.

So there are no measurable things that tells that there is something wrong.

Than I'm afraid it would probably a cpu problem.

Yeah well sometimes it's wiser to stop with the repair before you spend too much money on it.

But the only thing that it maybe could be.
Is the removal of the U18 - TL7702 ic.
The motherboard can work without it, and can give this issue.

However it's a small chance.
