I just want you to know, be careful.
And secondly:
Does anybody know what could I do. I have several holes in my closet, so choosing another place is not a suitable solution. Should I place some mirror, metal … between light and CP7. Does anybody have any idea?
I only mention this because I have experienced this problem on some computer equipment at some customers (Commercial printers). Transformer noise is not limited to only T5. Many older transformers do the very same thing…
Mostly the problem is that touch event are not fired. But from time to time, the events are fired but nobody touched the screen. I also figure it out, that the system became unresponsiveness.
It is certainly lights, because when they are switched off, everything works as expected. Also when I moved CP7 5-8cm away from the closet, everything works as expected.
When I used to work on Jukeboxes we used to have no end of trouble with the touchscreens. Any interferance from nearby electronics or metal can cause the touchscreen to detect an event or completely miss someones touch as the charge wouldnt be sufficient against the background…
Three possible solutions were
Move the touchscreen away from other electrical devices, you need to ensure a decent gap between the two.
Find the device thats causing the problem and create a screen between the two objects. Normally using something slightly Lead based
Check the screen isnt too close to anything metal, I think this primarily effects the capacitive types of screens
It’s a classic interference issue, I’d suggest you start by building a shield for around the connectors, then go wider as you need until you get decent results. It really is a harsh noisy electrical environment around Fluoro lights so your installation will likely need specific shielding for your situation, and trial and error will be the best way to deal with it - unless you have good instruments that can help here, whatever they are - but I’d expect that if you do you probably wouldn’t have been asking for our advice.
