Hello,
My Dyson Pure Hot+Cool, model HP00, no longer starts.
After disassembling and accessing the electronic motherboard, I found that the 16A fuse soldered to the motherboard is dead. I decided to do an electronic shunt to see the reaction, and the Dyson turns on for a few seconds and then turns off.
It is likely that a voltage control chip or a safety chip is dead, but without the electrical schematics, the repair becomes complicated…
Thank you in advance for your help.
Best regards

it was working yesterday, i opened it up and saw this mess. boardview and schematic uploaded for convenience.
PU200
pin 17 vreg5 = 0v ~ solder joint was corroded and flicked right off with my probe, was able to get clean and reflow, rest look fine.
pin 8 vreg3 = 0v
pin 13 en = .2v
pin 1,6 entrip1,2 = 0v
b+ and b++ = 19.5v
+5valw = 0v & 25+ohm to ground
+3valwp = 0v & 25+ohm to ground
i cleaned the board up just a little and can get more pics.
where should i be looking? thx... -
Hi there!

Symptoms are it doesn't barely cool down, and makes a chirping noise at the board.
Both fans on each side of the peltier are (now, after much cleaning) running smooth and silent
When you turn it on, the front 7-segment display flickers for a variable time, usually like 1 minute but sometimes nothing or 3 minutes... Then turn on solid (but still some... -
Good day folks. Having installed, or at least dealt with, a modest amount of cameras as part of my current job, I came across one aspect which seems to divide us in two schools of thought: those who suggest that a single PSU run ALL cameras and those who suggest that each camera have its individual power brick. For now, we went with the second option for all our installs, which is messier and takes longer to set up, but offers better redundancy, since if one brick were to fail, the rest would still remain up, whereas with a single supply....well, if it fails, ALL cameras go out. A single supply...
