Tx NR646 No Hdmi in/out

[saphire34]

Hello everybody. As it says in the title, I have an onkyo tx nr646 where the hdmi ports no longer work, both inputs and outputs.
Last night there was a storm. There was a lot of lightning. The electricity was turned off several times.
The speakers work correctly. Radio net works. Bluetooth works. I managed to update without any error through the usb port.
Can someone help me? Thanks in advance.

Buna din LA.
Most likely the HDMI IC(or ICs) are bad.

Here is the service manual for it. I am not sure if you just can sepal either that Q8000 on that HDMI aboard.as it can be flashed with firmware.

I have some threads on repairalmostanything forum. Tjmotter is the expert on Onkyos, though he quit repairing, but he still shows up once in a while on that forum.

The HDMI ICs do not get hot?
