Samsung 55" UHD TV Model UA55KU7531KXXA

Hi guys,
I have this fault that has me running in circles. This set was smacked by a power surge and i replaced the PSU. but now a battling with another issue.This set has 3 HDMI ports namely HDMI1/DVI, HDMI2 and HDMI3. Only HDMI1 has no sound when playing a bluray player on that port. Picture is perfect. 2 & 3 are perfect. RF audio is perfect.
Firstly i reset the tv to factory defaults and then get a weird picture like the colors are all in the wrong places. So i went into picture mode, advanced settings and found "Video format" had defaulted to CbCrY or something so i changed it back to RGB and got the picture fine but still no sound.
I then did a software upgrade also with the same results, no sound.
Can it be that something has changed in service mode causing the HDMI1 sound format to have changed.
I have no idea how to access service mode on this set as the remote only has a few buttons.
Any ideas?
Regards

there are no defect at your Samsung.. HDMI1/DVI it mean it handle only Video Signal with out Audio Signal. such PC out put.. the sound signal should be feed to the set with Audio Signal IN

Thanks Diah, this is only my second Smart TV that i am attending to and don't know their tricks. Can you believe that i contacted Samsung's Technical advice centre via a chat group and they did not have a clue what i was talking about...

Try them to see if it will work.

Hi Guys,
I will check the labeling option. I never noticed something like that on the Samsung.
Thanks for all your replies.

Follow-up: I experiment with my Samsung last night.
I have Samsung with HDMI/DVI input, I use my DVD player with it and get sound fine, but if you set the name to PC/DVI, then there will be no sound, you will get soundwith the input name blank or any other name except PC/DVI.
