This may be a long shot but I have a 4CH 350MHz Rhode & Schwarz Osc. The LEDs on the right side of the scope seem to be overheating and flickering either ON/OFF or changing colors. Each Channel button is supposed to be a different color which matches to the color of the trace on the screen. When I spray cold spray or compressed air, they seem to come on for a bit and start working again.
So far, I have replaced the power supply because I found it to be faulty as I noticed the fans weren't running. I also replaced the SMD LED drivers. The fans now turn on but there is no change in the LEDs. In the video, I sprayed compressed air and all of the LEDs turned off momentarily. (freaked me out!)
The scope still functions fine but the LEDs on this scope was an incredible feature. Every time you press a Channel button all of the measurement buttons light up the same color so you always know what channel you're adjusting.
Anyone have any advice of what may be causing this?
