      Corsair K70 LUX RGB dying LEDs
      by Pipolups
      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 🙄...

      LG 47LB5DF blown power supply board
      by cmlewis89
      Hi folks,

      I'm new to this forum. So my trusty 17-year-old LG 47" LCD recently died. As I was booting it up, I heard a hum followed by a loud bang, sounds of pieces flying around, and loss of power to the unit. Inspecting the PSU, I saw two obvious problems: a blown thermistor (bang + flung pieces) and a visibly bulging main cap. Inspecting as many components as I could with my Fluke MM, I diagnosed that the following components on the "hot side" of the board were also bad: one of the 2 main MOSFETs, main 8A fuse, small cap (25V 47uF) connected to main caps, and a blown...

      HP X360 convertible battery blown fuse error, not charging
      by drscoot
      HP Modelnumber: 14-dh0061nb​
      This laptop had a shorted cap on a Vcore section. After replacement is works again. But there is still a battery issue.
      The battery is HT03XL and with the built-in component test from HP, in the Power section, I get an error: Logic State: Calibration required (20), Charge state: Blown Fuse (42)
      I have another same battery, also with error: Logic State: Very Weak (70), Charge state: Blown Fuse (42)
      And a third battery TF03XL (looks identical) with error: Logic State: OK (0), Charge state: Blown Fuse (42)
      All these 3 batteries are charging...

      Insignia NS-37D20SNA14 intermittent LEDs
      by THE GTC
      So I use this TV daily as a second monitor for my PC or my Playstation - at one point a few months back I tried to fix the problem - but in the process, I figured out something that works so I haven't posted this for awhile. It is an annoying trick to have to do though, so I decided to post about it to see if anyone could spot what's wrong. It baffles me because it works on it's own half the time.

      When I first got this TV, I was told it wouldn't turn on, and of course I did the flashlight test, and the image was there. Also, the red LED on the front indicated that it had power (it...

      Identify blown component on HP ENVY X360 13-arxxxxx, Motherboard G1 13 AMD X360 18740-1 448.0GA03.0011
      by w00pz
      I have blown a component on HP Envy x360 with motherboard G1 13 AMD X360 18740-1 448.0GA03.0011.
      Unfortunately there are no schematics available and the component was so blown the marking weren't readable.

      I have marked it with a red circle in the attached photos - sorry for the mediocre quality I was too much in a rush.
      Hope someone will be able to identify the component.

      Many thanks for your help!
