    Hitachi Plasma TV P42T501 Factory Reset

    So I've got a Plasma TV that won't accept any inputs... it turns on but won't show anything at all. If I leave it unplugged for a week it resets and works again once I turn it on - but the next time I turn it off/on I have the same issue. I've tried upgrading it to newer firmware with an MMC card but the upgrade fails every time.

    So finally, I'm trying to do a factory reset, which is what the service manual says to do if the upgrade doesn't work. I found that I can get to the "Adjustment Mode" by hitting Menu+Menu+8+Select. Selecting FACT RESET flashes a few colors, then finishes on green as its supposed to. When I unplug/replug in the AC cord as the service manual says, nothing has happened. Nothing was reset. Any idea what I'm doing wrong?

      JVC LT-43C888 (manufactured by Vestel) does not start after trying factory reset, details below
      by masterm
      TV: JVC LT-43C888 (purchased in 2018). This is a smart TV with Netflix, Youtube, Freeview and other applications via 'Viewd' app store

      Problem with TV:
      - Netflix stopped working so i tried to do factory reset from the TV menu.
      - I confirmed on-screen but the factory reset did not happen even. It did not take me to 'first-time installation' screen as mentioned in the manual.
      - After waiting for some time, the TV went into a boot loop.
      - JVC logo comes on the screen and LED light flashes for some seconds, then it reboots again and the same thing happens

      Hitachi 55HDS69 55" Plasma TV - No Picture But Sound
      by KYBOSH
      Picked up a bahemoth plasma TV not too long ago and just now getting around to looking at it.
      No picture but you hear the TV static (white noise) playing loud and clear.
      The back was already taken off (and no screws were provided) as the previous owner had already taken a look.
      But it seems they didn't get too far and just left it.

      When I first took a look I was amazed at how pristine the inside looked.
      Its as if the TV had been in a time capsule.
      Caps looked like they were just pulled off the self.
      Copper coils had no sign of corrosion on...

      Hisense 55Q9G Android reset / factory firmware reload
      by mon2
      Hello. Have a 55" Hisense TV that starts to load the Android OS (no backlight issues) -> reaches the app screen where you can view the assorted icons including Netflix and always crashes at the same point just after this launch. If I quickly press the cursor buttons, the cursor can navigate to the settings menu but will power off just after a few seconds of this activity. Do not believe it is power related since the crash is very accurate in the boot cycle.

      After the OS 'crashes', the power does go off and the from white LED goes dark for about 20 seconds and then ON again....

      Reset/erase Hynix SC210 to factory default
      by pfrcom
      Some Googling made this seem straightforward, but it ain't necessarily so:

      First try was Hynix Drive Manager, supposed to be able to do PSID reset

      In Win7 x86 context, what shoddy software – this greeted me first time I clicked it from Start menu:


      After wild goose chase triggered by the OpenGL bit, I tried swapping graphics cards until penny dropped when it still objected to a Radeon HD3450

      How I got it work:

      1. Command prompt
      2. Change to install directory \Program Files\SK Hynix Drive Manager
      3....

      Chinese multimedia crashes on the home screen, could someone help with the software or factory reset?
      by LEONARDO DE FREITAS
      Hello everyone, I have 2 multimedia systems with a 9-inch screen that turns on and only stays on the Android screen. It is very likely a software update. I have 2 software programs here but the multimedia system does not start the installation. Has anyone encountered this problem? I would be grateful if you could help.
