Atmospheric discharge in DVI

Dear friends, I was presented with a lightning strike that hit the DVI output of my DM8000 japhar clone.  All for a Chinese HMDI switch. Below are the images of the components I need to replace. I need help, what is the correct specification of the components that signaled that they were damaged by the electric arc. I need to know where to buy these components. The dm8000 turns on, starts the power led and the hard disk. However, no signal and video signal are input to the main screen on the front. Thank you very much for your kind colleagues attention !! Deny H.P

R816/R817 = 2k
D402/D406/D407 = A7W SOT23-3 Dual Surface Mount Switching Diode.
D403 = WB1 sot23-3 I think, a zener diode the BZX84-C3V3.

I'm not sure what you ask but the removal of these components are mostly done with a hot air station.
When you mean, if I could give you some sellers which offers these parts, then I advice to use Google for searching for it.

I did not test with the SCART cable. I did not see the front main display screen initialize so did not perform this test. Thanks for the tip!
