So I have two dmgs with overheating regulator boards. One has a backlight and rca prosound and only gets hot when I use it with arduinoboy. The other has a backlight, rca prosound and 1/4 prosound therefore I had to move regulator board. That one gets hot just playing it by itself. I have done tons of googling and searching and it seems that adding a resistor can possibly solve these problems. I’ve seen so many different values of resistors recommended and with my lack of knowledge on resistors it’s made it rather confusing. I ordered 30ohm from Amazon. I’m hoping that will be enough. Is there anything else I need to know about the resistor?
Also I believe these backlights have resistors built in. Shouldn’t this have prevented the overload?
I would really appreciate some advice. I’ve posted in other threads but they just get lost in the heap and I haven’t gotten a response
Thnx.
