One of my studio color 575 has a problem with the logic board. The board seems to have no power, the display and motors are dead, but the LEDs for DMX and Lamp status are working. I replaced the whole power supply but the problem is the same. Should I replace the whole logic board? I can not believe its damaged, because the LEDs are still working..
You were right. U13 was the faulty component. Now, another washlight has the same problem. On the schematic there is the regulator LM2596 but on the board there is the following regulator: LM2576 HVS 5.0 Do you think this could be the problem or do you think it doesnt matter which of them is on the board?
The difference between these two units is: The LM2596 regulates between 7 - 40 V and the other one between 4,75 - 60 V
