✅ Boiler Mural Peisa Diva Unica does not turn on the display

As the days of lower temperature are about to begin, I set out to check the boiler, after cleaning it, I connect it to the outlet and it does not turn on anything on the display, as it would lack power supply, the first thing I do is check the take and arrive voltage correctly, then disassemble the box where the plate is located and voltage also arrives, check the fuse and it is also fine. I would like you to guide me that the platelet broke down and needs to be replaced, I have read that it is quite expensive. Thank you very much to this forum for exposing this problem I already took out the board and I don't see component that is "burned" Can I feed the board outside to take measurements? I leave of the board

Hi! Sorry for the delay to respond is that I was traveling due to family problems and today I was able to perform the test as indicated by “MDQ Heating” Perform the test with the serial lamp and measured at the input of the transformer obtaining voltage, mdí

the output and also has voltage, so I interpret that the input protections are correct. Then I turned on the display and turned on again, lightly turned on the lamp series that did not turn on before, this indicates that there is a consumption. I do not know if this should be correct or indicates that there is an abnormality in the plate. I leave a photo from now thank you very much

Hello People of "I repair" After quite a few days analyzing what was happening with the control board and the display I could find the problem, a capacitor of the power supply of the display board, in sight it did not seem that it was defective, was right “MDQ heating ”Who was advising me to look at the capacitors, thank you very much. I will tell how I discovered the fault: When testing the serial lamp without the display connected, the 60W incandescent lamp did not turn on and made the measurement with a multimeter on the integrated L7805 CV di regulator It gave me the corresponding 5V and when I connected the display cable the very dim series lamp was lit (indicating the passage of a current) and when measuring the integrated it gave 0.3V a short. I test the plate separately with a cell phone charger that has 5V on its output, this previously analyzing that the 2 cables that are separated from the rest are effectively where the plate is fed and when testing did not turn on, I measure the voltage in the At the time of the test and 0V, the short was on the display plate, I will test the easiest 100 µF 16V capacitor that is parallel to the input of the power supply, desueldo and test, the capacitor was short. Well, on Wednesday when I open the electronics house I will buy it since this was a Sunday and Monday and Tuesday holiday on May 1, and I think somewhere I have to have a capacitor of this value, I start to stir in the things that I keep and I find an old motherboard that had many electrolytic capacitors finding 5 of the value that I needed, I discard 1 I measure it and all the parameters were correct, salary on the display plate is a bit short since this was vertically placed and I had it that put horizontal, but with a little strength left, then I do the tests again and it worked. It is already placed in the boiler and at the moment it worked correctly.
