    LEDs for TV Backligth

    Hello everyone
    I'm new to LED strip LED replacement.
    The original LED comes with a single internal LED or chip. I only get at the moment LEDs with two internal LEDs or chips.
    I understand that this is due to the tone of the light they emit.
    My Doubt is:
    Can I use the LED with two internal chips without problem?
    Will there be much difference in the picture?
    I'm going to replace all the LEDs.
    Both LEDs (original and replacement) are 3V and the same size.

      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 🙄...

      Best place to source RAM chips? 8GB 820-00850 boards to 16GB or 32GB
      by ugamazing
      I'm looking to upgrade several 8GB 820-00850 boards to 16GB or 32GB for personal use. I am curious what the best practice and process is for sourcing new replacement chips, and what vendor(s) you guys prefer? Another question is, how do I find compatible chips and their corresponding part/model numbers? For example, in the 820-00850 schematic, the DDR chip U2600 model listed (EDFB232A1MA) corresponds to 1x32GB chip. Of course, I would need 4x8GB chips to replace the 4x2GB chips currently on the board. How do I find compatible 8GB chips? Is it as simple as searching "BGA178 8GB 2133"...

      WSON8 NEW Bios Chips READ, ERROR, ETC.
      by feherhollo
      Hi,
      I asking for help on some new WSON8 256MB chips. Please share your experience. I faced error on some new chips on read, erase, write with different programmers. These new chips are not exist in any programmers database. (GD25B256D, XM25RH256, W25Q256JV so on.)
      I'm using RT809F V.5.0, EZP2023 Pro, CH341A Green

      For the exact experience with GD25B256DYIG is RT809F erase the chip under 33sec. This kind of 256MB chip normal erase time is 70-120sec so I think not all the partitions are erased. If I do blank check or reread the buffer says FFFFFF but when I write the correct...

      Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
      by acedogblast
      This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

      There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

      Samsung un65h6203af led replacement question
      by tmhobadcap
      This tv is with sound but no picture. When light shines on the screen, we can see the image. This is a typical backlight problem. I opened it and found quite a lot of the leds are damaged. But the damaged ones are all shorted. No one is open. Is there a special reason? (From my past experience, both can be happened)

      When I supply 3V to each of the good leds, the currents range from 105mA to 154mA. From these figures, I think the leds are 3V and about 0.5W. I plan to replace all the damaged leds only (because the price of the led strips is very expensive), but I could not find 3V 0.5W...
