Corsair K70 RGB led issues

[audiofanaticz]

So this is now my 2nd keyboard from them.

The first keyboard with the corsair gaming trampstamp had the W and A key start to change colors by itself when you tap on the keyboard, in under 2 months.

I paid the deposit of a new keybaord to corsair to have an rma replacement shipped asap so I was not without a keyboard.

Now the new keyboard with the sleek corsair logo everyone loves is doing the samee thing, but this time on the Space bar.

 

While the keyboard still works fine except for the occasionnal double taps on some of the keys, its very annoying to see a key I have set to white light up blue, green, purple, etc.

At this point doing a 2nd rma for a 3rd keyboard seems pointless.

I guess its just time to switch back to Razer, and hope that the knnock off chinese cherry switches are held to a higher standard of quality control.

 

I have a video uploading now with the issue, still about 20 or so minutes left on the upload.

In the mean time here is the old keyboard from 5months ago that did the same exxact thing, just diffeerent keys.

Ok so I posted this in a more popular thread than mine, but Im going to post this here as well..

 

I have taken mine apart.

IMO the design is horrible.

There is no support under the pc-b.

How it works is you have the aluminum top cover that is held un to the plastic bottom cover by 15 screws or so.

The switches are sandwiched between the aluminum front panel to the pc-b, the only thing holding the pcb to the alumiunm  top half is the solder joints.

So if you are somewhat of a hard typer (which I would say I am since i alway bottom out the keys) the pc-b will have slight flex issues.

There is only 1 screw that screws from the pc-b to the aluminum top, and that screw is a grounding screw that has a small black wire attached to it.

Here are some pics.
 

There are 24 tiny screws that hold it together, 2 of those screws are hidden. 1 is under the corsair logo, the 2nd is to the right of the volume knob (the half round piece of plastic pops out).

 

A couple pics of screw locations

 

In this picture you can see the plastic stand offs of what those 24 screws get screwed into.

You will also notice that these stand offs go right through the pc-b providing no support to the pc-b directly to prevent any pc-b flex.

 

This is the only screw that secures the green pc-b to the aluminum top half, however it seems like it is just there to provide grounding via the black wire with the ring terminal.

Maybe it is to help the keyboard to resist static shock.

 

This picture shows the switch for the space bar. notice how it sits flush on the aluminum front.

 

Same space bar switch, with just a tad of pressure and  no longer sitting flush..

 

Another thing I noticed is you can signifigantly wiggle each key switch fairly easy from side to side.

Here is my old Razer Blackwidow ultimate 2013 (over 2 years old and flawless), I put this thing threw hell, and its still working to this day.

I gave it to a friend after buying my Corsair K70rgb.

But first I had some fun with it....

 

Right off the bat you can tell its assembled better, stronger.

Here I am removing the keycaps getting ready to take it appart.

You remove the screws out of the bottom of the keyboard and your able to remove the top half of the keyboard which grants you access to more screws that screw the metal covered pc-b to the bottom half of the keyboard. The pc-b has more than adaqute support underneth, and has no flex, even when the keyboard is taken apart.

Id say a lot of strength comes from the bright green metal layer, and also makes the LEDs appear brighter than they are becuase they are reflecting off a bright object not a dark surface.

Keep in mind not only is the pc-b screwed to the bottom half, but it is sandwiched between the top and bottom half for a real good flex free issue.

 

Like I said I put it through hell, I figured it wanted a bath......

Yes it still works flawlessly after getting soaked!!

You didn't seem to mention this as part of your troubleshooting, so IMO update the firmware and corsair software to latest versions if you haven't already done so.  I had backlight issues on my K95 RGB purchased close to launch where 2 LED's wouldn't change color at all, but after updating the firmware I haven't had a problem sense.

 

When I took apart my K95 (ended up with a drink spill while unattended at a lan party, was more than dead but wanted to tinker), I took it apart and I was actually impressed with the construction.  It felt like I could kill someone with it with a single blow lol.

Nothing was spilt in the keyboard, it is clean as can be except from a little dust that you will find in any house for the most part.

The firmware is up to date v1.30, its nto a software issue.

When you tap on your keyboard and they start changing colors proves that.

The problem is not the leds not wanting to change colors, the problem is that something becomes loose and any vibration is causing other colors of the leds to illuminate.
