What Qnix monitor does 120Hz?
post #5722 of 6483
I bought my monitor in June 2012 so I've had my monitor for close to 11 months now.

In the last few months, I noticed there was some flickering upon startup, but it was very faint so I thought maybe I just never noticed it and continued to ignore it.

However, the last few days it looked like the monitor was flickering more but I thought it was my eyes as I was spending more time on the PC so I ignored it until last night. It started just "turning the image off" yesterday night - i.e. the power on the monitor was still on, and it was still blue, meaning it was receiving a signal but there would be no image. If I turn off the monitor by the power button and turn it back on, it appears to work for a little while (can be anything from a minute to an hour) before the process restarts. I've noticed it does indeed flicker now.

I bought my monitor from BCC, is there anything I can do about this? If not, is it a simple fix for a person that's ok with electronics?

Thanks!

There's always been a problem with one of the capacitors on the back light PCB over heating. This is what is causing your flickering problem. Pretty soon your back light will probably stop working altogether.

If you ask BCC they may ship you one, I've heard they're relatively easy to replace. They've usually sent the component for free if people have had problems shortly after purchase, I'm not sure if they'll send you one for free after 11 months though.

Thanks for the speedy reply. I have to admit I've stopped following this thread so I'm unsure how this exactly works. Does that mean there's a separate PCB that I can simply unplug the cables from and then replace, fixing the problem?

Search isn't proving as useful as I'd like it to be frown.gif

EDIT: Just tried searching again and I found similar problems to what I was having, will continue researching.

EDIT2: Seems replacing the PCB is quite a simple fix, will email BCC and see what he says and call PayPal to see what they say too just incase BCC aren't playing friendly.

I'm not exactly sure how this daughter board is connected to the main board, but I imagine it's not soldered or anything that's a complete hassle because most people who have reported a successful fix didn't complain about the task being difficult.

I haven't followed the thread in about 6 months either, so my information is 6 months old. smile.gif

It sounds like it was as simple as requesting this daughter board (my guess is it's a voltage regulator for the back light) and then installing it. If you take the back panel of your monitor off, you should be able to see the board, it's the smaller of the two, you can then assess what you would need to do it in order to remove and replace it.

Yep, it seems to be a small daughter board which you simply screw in and plug the cables into.

Once again, thanks for your help!

No problem.

Their English isn't very good at BCC and as far as I know there are two versions of the board (one has a green PCB and one has a blue PCB), I'm not sure if they're cross compatible or not.

I'd advise taking a photo, and putting a red circle around the PCB and an arrow with text saying 'I would like a replacement for this.' Better to be safe than sorry.

Let us know how you get on, I'd be interested to know for future reference in case I ever need to do the same thing. thumb.gif

Almost all of them based on reports in the PLS threads. Some have done 144 (haven't personally tried above 120 yet) Some have scan lines at 120, others like me have settled at 96Hz mainly due to lack of GPU power.

Any doubts still that they truly overclock to this degree must be just sour grapes. It has been verified a few ways that there is no frame skipping or what have you.

Yep, I've tried to explain things more simply just to save time for both parties. I'm wondering whether I should just sell this monitor for slightly cheap and pick up a Dell U2713HM. Then again, I've heard of some bad experiences with it too so I'm not sure I'd want to go with it. Hopefully my monitor will just limp along until I can fix it - would be rather annoyed if it died before so as it's my only monitor.

I'll open the monitor if they ask me to, otherwise I'll leave it as it is for now.

Will definitely report back!

Interesting.

I was under the impression that the PLS panels only came in matte but looks like they have glossy also.
