Hi members, have a noco genius 10 that has all led's flashing. Did any of you come across this issue?
Thanks
Thanks

Re: Noco Genius 10
If the Overvoltage, Battery, and Standby LEDs are flashing together, either the charger's internal temperature is too hot, or the ambient temperature is too cold for operation. If the charger's internal temperature is too hot, the charger will stop displaying the error and resume function after the charger cools down. If the ambient temperature is too cold, the charger will resume function when the ambient temperature rises. -
Re: Noco Genius 10
Unfortunately all led's are flashing, not just those you mentioned. Am trying to reverse engineer the pcb so hopefully will get to the issue. Measuring some voltages, the power supply is also flashing on and off. There don't seem to be any shorts though on the secondary side. Something is forcing the psu shut down then reboots again.Comment

Check electrolytic capacitors.Comment

Re: Noco Genius 10
Capacitors checked. There is also a pfc circuit that boost the dc voltage to 380vdc. I managed to trigger it and the input dc voltage to the chip was correct, but the power supply still failed to work correctly. At that time the secondary voltage was around 4v rather than 15v. Just to make sure I ordered a new psu chip, but I don't think it is the issue.Comment

Check the feedback (optocoupler, tl431,..) if there is one in this block.Comment

I have a pioneer A-307R here and what it does is flash all of the leds on the front and nothing more.
I got the thermal camera out on it and saw that Q451 was getting hot, so I removed it and the lights now come on as normal, but obviously that part of the amp doesn't work.
I tried replacing it, but it goes back to its flashing lights thing again.
I noticed too that on the back of the board R465 - R467 - R 469 are all getting red hot (over 100 degrees C)
Im guessing I have a short here somewhere, but so far I have not managed to find...10-05-2023, 03:51 PM -
Hi,
I am trying to fix this DK10FG board for a friend. It is not powering up.
When I plug-in power adapter, its DC IN led and Caps lock start flashing. Even cpu fan gets on/off kick like flashing leds. No battery attached. Nothing happens on pressing power button. I checked the charger IC and it seems fine. (ACOK - 3.3v). Re-programmed the bios but no luck.
I checked SIO chip NPCE885LA0DX and here's the reading
19,46,76,88,115 | P3V3AL_R --> 3.3v
102 | P3V3AL_EC --> 3.3v
4 | P3V3S --> Fluctuates from 0.2v to...10-06-2021, 11:17 PM -
Hi there !
I'm having an issue for several weeks with my quite old K70 LUX RGB keyboard. I haven't used it for few months, and once I setup up again my desktop computer, I got several dead LEDs on that keyboard. I tried the Corsair troubleshooting thing (disabling options in iCUE, ...) but nothing changed so I conclude that for some reason some LEDs went in retirement...😅
Decision taken to change these LEDs as I have access to desoldering iron and binocular magnifier, I wrote a ticket to tech support, hopping to obtain the LEDs reference and... They refused to tell me 🙄...10-08-2024, 11:58 AM -
Got a new victim:
AcuRite 5 in 1 Iris outdoor weather station not updating the temperature / humidity anymore. The original sensor is a SHT21. Also there are identical other sensor manufacturers. I chose the HTU21D to replace the original SHT21. Both have identical specs. I've had two failure modes with these sensors.
A: outside temp stuck at -40?
It's cold here at times in Canada, but not that cold!
B: stuck at some temperature and maybe updating once in 12 hrs or so.
Easy solution is to go to AcuRite website and purchase the sensor. Right?...

Hello Community!
CASE DETAILS
Promblem Signs: Backlight on 1 sec off 7sec > repeat && Red standby light: 1blink, off 3 sec, 2 blinks, off 5 secs, 2 blinks, off 3 sec, restart cycle
13V present on powerboard output. Backlight continues flashing after removing cables to pannel one at a time and even with both disconnected. NOTE: backlight STOPs flashing and remains on when connector between powerboard and mainboard (note Tcon built in) is disconnected.
Tried inserting firmware on USB and left it in for a few hours, but no change
