Crashing crazy image crashing functions (board code =715g5172-m01-001-004k) | Ci regulator u701 g1084-33 of 3.3v which I had, 4.3v power supply changed | U701 3.3v gergulate; u415 1.8v regulator but at its output it gives 1.5v which is normal because it has a voltage divider on its grounding pin which drops the voltage by 0.3v so it can have a voltage of 1.5v at its output! make the replace hug | orlando lott |

Uce d16-15-al replacement | Rinnai heater model reu 85 was not turning on due to a defect in the uce d16-15-al. As I had difficulty finding this model I ended up buying it on Aliexpress with the following description (1 set of 14 wires universal DC 3V gas stove double ignition with temperature control and ignition pulse display) and despite having an LED that is not present in the original it works perfectly. | littlecarlos | |

Turns on but tsound is no sound, and the output amplifies normally | In my case, as the 12v from the pre and p-on output that usually cause this were ok, I walked from the output backwards and arrived at ci u107 and u108 without power. The cause was the u803, the 5v regulator located on the top of the board. | A piece of advice for anyone who gets these Philips nx5, nx7 boxes with a power supply defect without calling: have a high budget and already carry out preventive maintenance on all its chronic defects. changing the famous electrolytics around the computer, micro switches, cleaning controls, etc. so you don't have to disassemble everything again later, especially during the warranty. The worst thing about these boxes is disassembling and accessing the plates, a lot of work! So it's better to do it all at once. And tsound are still these surprises like what happened to me when I repaired the power supply and it had no audio due to another defect that had nothing to do with the power supply. | Magrão tk |
