Need help with this Avionixx Class T amp

[powerT]

I have an AXT1000.4
It has 2 Tripath chips in it.

The amp goes into protect mode immediately upon powering it.
I dont know much about repairing electronics but decided to just compare the semiconductors on each channel to see if there measurements would be the same.
I found 2 output devices wich were measuring different from the others.
the devices are labeled w34nb20

There are 2 other devices that are in the power supply which are not measuring the same as the other devices in the power supply.
They are p80ne0

I think if I put new devices in there places maybe the amp will work.

Or maybe someone knows how to fix this amp..
