Still no signal even after putting it back together. Does anyone of you experts have any suggestions on what i can try to verify a broken pcb? Unfortunately, i do not own any electric equipment to check for damage. So i guess this will make this process close to impossible, but i thought i might give it a shot.
I always knew this day would come eventually but it took me by suprise this morning as no problems occured beforehand what so ever. I had it successfully OCd to 96hz for all those years, so this might be an issue as well.
either the panel died, or a board component died.

when you say black screen do you mean is emitting black, or zero illumination?

you'd have to know what to probe with a multimeter, if its a board level component. (busted cap/mosfet maybe? that's how most of my TVs have gone)

GerryTheLeper Does anyone know if the 2700 can be overclocked like the 2710 can?

Chowchilla Wow, My first post here was 2014!

Stick rocking my QNIX though I'm after an upgrade. Is there anything around the same size that's as good value?

Many thanks!

Same thing has happened to me twice. I bought a Qnix back in 2012/2013 and had to buy a new one in 2014, which then lasted until recently. The original power brick did run pretty hot and I bought a new one that didn't run quite as hot. I kept the panel from the first Qnix and was able to use the second PCB to continue running 120Hz. It's very likely that PCB capacitors and/or mosfets burned out due to heat/age.

I still have a 120hz-capable Qnix panel to give away if anyone is interested.

Luckily found a new but opened box of an Acer CZ380CQK (38" IPS 3840x1600 75Hz Ultrawide) which works as a much better secondary monitor replacement and now I have a vertically stacked Ultrawide setup.

Not that i know of. I tested it and it stays pretty cool for a pb that is. How high are the chances that the cable or dvi port on the grafics card are broken? Slim to none, right? I have no possibility to test the monitor on another pc. i purchased the hp x27i as a replacement and its a pretty huge upgrade tbh. was not expecting that.

Since these boards are like hen's teeth now I'd keep it and try and get it repaired. The company I bought mine from has gone out of business so no luck for me there!

Ugh, that sucks - I was planning to upgrade GPU with the 4000 series, didn't realise DVI-D is already dead.
Looks like it's 1080Ti for a few more years, and then decide what to do with this monitor.
