    jvc lt49c862 firmware needed (I think)

    Hi all, ive been asked to repair a jvc lt49c862 , basically when I switch it on it lights up (blueish so it needs backlights replacing) the jvc logo appears then it goes off again but all the while the standby light continues to flash constantly, i tried changing the main board to one from the same model tv but it didn't work at all so I'm guessing that board is broken, I would be grateful if anyone could point me in the right direction...

    Thank you in advance

              Firmware file for LG SK10Y Soundbar stuck in Please wait loop needed
              by Daniel Larsson
              Hi,

              My LG Soundbar, SK10Y, has somehow ended up in an endless "PLEASE WAIT" loop and I am now starting to suspect that the firmware is causing this, and I can't manage to connect via the app to push a new firmware in as it never really starts.


              I can trick it to start via HDMI ARC and it actually starts up, flashes OPTICAL and then goes to ARC where the sound (including sub) is perfect, but the white led indicator keeps blinking and after 20 seconds it says "GOOD BYE" and shuts down.
              During these seconds the function button is not working...

              [Help Needed] Yatour YT-M06 (Pioneer 1) – Firmware or Schematic Request
              by EduCabral
              Hi everyone,

              I'm currently working on reviving a Yatour YT-M06 CD Changer Emulator module for use with a Pioneer 1 interface (specifically with a DEH-P5950IB head unit).

              While the unit is recognized as a CD changer, none of the USB, SD, or AUX features respond, which leads me to believe the firmware may be corrupted or incompatible.

              🔧 Details:
              • Model: YT-M06
              • Interface: Pioneer 1
              • MCU: Fujitsu MB89F202
              • Goal: Find a valid .bin firmware file or memory dump from a working unit

              I'm happy to attempt flashing, analyzing memory dumps, or doing hardware-level...

              Firmware file for Marantz NR1501 needed
              by Daniel Larsson
              Hi all,

              I picked up a Marantz NR1501 that the seller said did not produce any audio, but was starting up just like normal. This was indeed the case and the hunt for damaged components started.
              After confirming all voltages and replacing all caps on this godforsaken HDMI-board I finally got sound from the AUX input, but all digital inputs are still dead.

              The service menu shows no DSP version so I desoldered IC1604 that should have the serial flash DSP firmware on it and made two dumps that turned out identical.
              The content of these seems to be useless as far...

              Lenovo X1 Carbon Gen 2 Touchscreen Firmware needed
              by neo2010
              Hello,

              I accidentally flashed the wrong firmware to my Lenovo Laptop Touchscreen. Now it is not recognized anymore in Windows 10. With Linux, I get the Device Listed as ELAN 04f3:000b USB device. I have modified the original Lenovo Flash Tool and tried other Firmware bin files but without success.
              The screen is the WHQD version. Can anyone provide a firmware bin file to reflash the touchscreen controller? As it seems that the controller is in recovery mode.

              Thanks in advance

              TV Felix FXV-4221 - firmware needed
              by gkoukoul
              Hello!

              I have a Felix TV that turns on, shows the "FELIX" logo then shows a "WISDOM SHARE" message and doesn't do or respond to anything else.
              I'm assuming a firmware flash will fix it.
              I can't find the firmware file though, anyone has it please?
