Huge problem with my denon dj sc Live 4, The Screen freezes & completely unresponsive (to touch). I totally can’t even figure out what causes it & How it happens, it works for one or two days & the 3rd day it completely freezes. I mostly use my controller with a Laptop, so it’s becoming tough & unbearable to operate with the controller as the touch screen is the only way to connect to my laptop. Is there a way or a press button cheat where I can access the source button without tapping into the screen?
It Now seems that The SC Live 4 is a wrong investment for me…I’m sick & tired of the screen freezing & failing to respond to touch has become persistent as I want to connect to Source & Denon doesn’t have an ENTER or OK button to connect to the source. Even after several updates & factory settings on the firmware & updating back to the latest version, Screen still refuses to work. then, all of a sudden, it will work for a couple of days … I really don’t understand the whole issue & what caused it. I even e-mailed Denon DJ, but they couldn’t give me a reasonable solution. They told me I should use its original power brick…Of course, I do use its original brick. I’m just completely exhausted by this product. It’s the worst, worst Investment I’ve ever done!
It sounds to me like a grounding issue wherever you’re connecting your device.
Denon’s use capacitive touch screens which work on tiny currents of electricity from your body to respond. Ensure your electrical supply is earthed correctly, you’re not wearing clothes that induce static, you have shoes on that don’t create static, or a carpet/rug that doesn’t induce it.
How Robust is Uganda’s power grid? What sort of standards do the electricians work to?
Wow That sounds like a very defined & deep problem because I wouldn’t know if the shoes I’m wearing create static. But generally, we use 200 - 220V here in Uganda. And it does work perfectly sometimes…& sometimes it freezes completely when you power it on, The press buttons (like scroll, Menu, view) work perfectly while the touch sensitivity remains unresponsive. I can’t even figure out the issue at all. It has become the biggest riddle of my career.
No I don’t have those designed gloves nor is there any capacitive touch device connected to it. It just does that whenever it feels like it. then u find it working on any random day. Then it works suddenly the next day. Just keeps on doing such & it is so draining & too risky for business. Every time I leave home for a gig I have to try it & sometimes it causes issues when I’m just setting up my gig. Don’t know what to do for real.
I’m not saying is there any device connected to it, I’m asking if you own any other capacitive touch devices so you can test if there are similar issues.
It’s possibly more sensible buying a dedicated DJ controller if you’re using it with a laptop anyway. Something like an FLX-10 sounds far more suitable.
Does the touchscreen work if you touch a metal part of your SC live 4 with the other hand at the same time?
Does the surface of the jogwheels work correctly in vinyl mode?
If, as @STU-C indicates, this is a problem of poor earthing, you should theoretically also encounter detection problems on the capacitive jogwheels in vinyl mode (random detection of your hand or music that continues to play even if your hand is placed on it).
This will determine whether it’s a real earthing problem or simply a screen fault.
Now I came to understand…it was a completely wrong investment…I was just swayed by the functionality it was supposed to give me…& moreover, I wanted to learn to play on a standalone without a laptop in my free time…but now, it’s just the worst investment I made in my life.
@Gaian No it doesn’t work…I don’t think there is an earthing problem. It doesn’t work whether or not you touch a metal part. It switches on well…all controls (buttons) are working, the only problem, is the screen doesn’t respond completely. U can scroll through the demo tracks or the menu using the scroll & press buttons. Tapping on the screen, Nothing, Nothing at all. Even when switching off, You have to long-press the power button because there is no other way u can shut down from the screen.
Do not blame the appliance until you have determined whether it is a problem related to poor grounding or not.
A bad grounding is usually an external problem located at the level of the electrical installation (wall socket or power strips). The device itself is not the cause here if the environment is not suitable for its use and you could encounter similar problems with any equipment using capacitive detection technology.
However, if it is indeed a screen malfunction linked to the device, it can happen, no manufacturer is immune to a manufacturing defect. This is precisely why there is a warranty on the product.
This is why I asked you the question about the touch detection of the jogwheels in vinyl mode on my previous post.
You did not answer clearly on this point concerning the vinyl mode. Because you will not see any malfunction if you do not use it in vinyl mode.
I always use it in Vynyl mode. Yes jog wheels work fine…Like I said, Everything on this controller works fine except the screen (the most important part). And of course it’s time to blame the appliance (or may be my luck) now (although I do understand no manufacturer is immune to malfunction), But the whole country can’t have faulty electrical wiring. I’ve taken it to several gigs, most of them with very reliable power connections & protectors, & it has done that on almost half of them. I Bought it last year in July/August from Amazon Dubai, & the problem began just a little after 7 months. At first I didn’t think it was serious as it worked the next day or after restarting, but later on, it became persistent & could just malfunction for three-four days consecutively & then works suddenly.
I have limited knowledge of electrics and wiring, but as I understand it, different nations have vastly different approaches to their regulations/laws and methods of installing electricity in our homes and businesses.
The UK for example have a very distinctive 3 pin plug that is almost unique to us (aside from some other commonwealth country’s who adopted it), the top pin is purely for Earth/Grounding and its generally seen as one of the safest out there. The US and most of Europe use 2 pin connectors, although Europe have started adopting an earth/grounding connection on the locator springs if I understand it correctly.
This for example is what pops up when I google electrical wiring in China, can you imagine your gear connected to the end of that.
We also have 3 pin plugs in Europe, just the third pin for earth is not a male pin but a female pin. The male earth pin is located at the wall sockets or electrical power strips.
Sometimes you’ll only have a live/neutral 2 core within the cable (no earth) so the third ping on the plug is just to activate the safety device on the socket, if the middle earth pin isn’t inserted into the socket then you can’t insert the live/neutral pins. It’s a design feature to stop children sticking things in plug sockets, that’s why the top pin is slightly longer to activate the lock mechanism. Most TVs only have a 2 core cable but a 3 pin plug on them.
If it’s 3 core then the earth pin will be copper, if it’s 2 core the earth pin will be plastic, unless someone has wired a new plug on the end using a normal 3 pin plug with no earth core going to the pin.
Just checked my Pro Go, it’s 3 core. Copper earth pin on plug + a 3 barrel connector going into the transformer. TVs normally use a figure 8 (2 pin) only live/neutral with a plastic earth pin on the plug.
