Question Screen randomly turning off on SAMSUNG QE55Q700T QLED 8K TV ?

[RyzaGul]

So my TV is 8 month's old and randomly started turning off the screen but sound keeps on going without an issue.
I am by no means a technician but i do like repair things on my own, but this time i can't figure out what is going on.

Here is an image

I tried to unplug everything and reseat it = no luck.
I had some brown liquid spots on the PSU board but cleaned everything with some alcohol 99% = no luck.
Tried different cables = no luck.
Checked the backlight strips all of them are working

It just randomly stopt working, i had contact with Samsung and this could be send back (RMA) but could take up to 2 months to just receive the tv and then they'll decide if it's fixable or not, i would then get a partial refund of the marked price which was 2.059euro but now is around 900euro, this TV is 8 month's old!

P.S: i don't have any electrician equipment so i can't check levels on outputs etc....

what do you think i can do ? before i trow it in the dumpster ? altho i was thinking of taking out the speakers sinds they are amazing and create my own soundbar 😛

There is no picture at all, only sound, i use HDMI but even without HDMI by just pressing the Menu Button is also not showing the menu options, so even TV normal tv is not working, it stays black screen but you can see that something is happening in the blacks when you press the menu button.

Also Samsung told me to open the back panel if i feel okay doing that to check connections and i did, i forgot to mention that in the first post, after that i went back to them and told me that removed my warrenty XD so wtf Samsung
