    Cheap LED grow lights flashing

    Hia, I'm pretty sure am having an issue with an LED driver on my grow lights.

    One side of the lights were working correctly at 70v the other day and the other side was jumping around the place.

    Regards,

    Okay either you have an issue with one more LEDs pulling to much current being not lighting at all or dimmer than the other one in the string or an issue with the switching power supply because the start capacitor is having a high ESR ( 100uf or lower value capacitor ) or because of a bad switching power supply regulator ic chip

    The first thing that I would recommend is that you if you have an external power supply that you adjust the voltage try testing each LED light separately if possible or a group of LEDs and note the current of each one or a group of them and you find one with a higher current or dimmer that other ones this is with the same parameters all being the same this is what you are looking for trying to figure out what is going with the issue that you are looking at

      ITE IT8390 (IT8390E-256) programmer "ITE Download Board 4" user manual + firmware, flashing ITE ECs on the cheap
      by H34TO
      Recently I've gotten into EC flashing due to my broken laptop(s) and started frantically searching methods for flashing the IT5571E-128 chip on the cheap(due to me beaing a student and not having a job) and noticed that ITE newer chips can be flashed via ISP (In-System Programming) either via SMBus or the KBC (EPP - Enhanced Parallel Port) interface. While these can be achieved with programmers like SVOD4/3 or the RT809H/F those options are WAYYY out of my budget so I was horrified. But recently I stumbled uppon some programmers on aliexpress that claim they can program a variety of ITE chips...

      When your mom is complaining about her new cheap lights
      by evilkitty
      My Mom bought some cheap motion sensor lights on wish... then complains about about batteries and this thing chews though them, well it uses 4 AAA batteries and a pack of rechargeable ones is about 13 USD

      well since it uses 4 AAA and rechargeable are 1.2v and non-recharge at 1.5 this thing must work with 4.8-6v, I'll shove a USB cable on it, infant i will use a broken phone charge cable... dam this thing uses 430 mA and they made it battery powered...


      lets ignore the fact that i thought the board fit both ways... and the wire color is reversed going to the board...

      Elitebooks (820, 840 etc. all gens) and those continuously flashing Power LED + flashing CapsLock LED
      by STKR123
      As the Elitebooks (820, 840 all gens) only show flashing Power LED and flashing CapsLock (continuously) + a very soft "ticking" noise near the DC Jack,
      I wonder if re-flashing the BIOS might be of any use here.

      As far as I understood, steady flashing either means insufficient power or a CPU/GPU/Motherboard issue. I use the original 65watt power supply.

      There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard reset, reseat the RAM, clean the RAM,...

      Vizio E55-F1 dark backlight zones. LED failure or Dimming Zone Driver?
      by howardc64
      Problem

      Fixing a dimming zone TV with LEDs not lighting up. Dimming zone circuit introduces added variable to diagnose LED and/or Dimming Zone Driver board? Some 1/2 rows of LEDs appears to be out in active dimming zone off AND some brightness flickering with active dimming zone high while playing changing video



      Model & Board Pics



      Conflicting Spec

      Vizio indicate this TV has 10 dimming zones. However, LED strips and Zoned light driver connector suggest 12

      Sharp LC-32D44U - Power and OPC lights flashing
      by TVAddict
      Hello everyone, so the problem is the tv would seem to power up when i hit the power button as i would hear a relay click, sometimes it may give me a good picture for about 5 secs or so, sometimes i get a black screen, then shortly after it will click back off and i get power and opc lights flashing together twice followed by one flash of the opc light then it repeats.
      Please correct me if i'm wrong but i understand the flash sequence indicates a possible power supply problem, can anyone say if this is accurate information? So going on that i went ahead and tried a factory reset, checked...
