      I get no google hits at all on that model number - is it correct.
      Is it LCD or LED
      What does it do with a source connected
      Is there sound
      Can you update your profile with country and mains voltage

      Welcome to the forum-
      We can help a lot more if you please post good clear pictures of the whole chassis, and then pictures of each board, front and back (in the same orientation) and close up of connectors, (max resolution 2000x2000 and 2MB) using the manage attachments button, which is found by clicking "go advanced" under quick reply.

      Please do not post inline and offsite as they slow down the loading of pages.

                      Good job!

                      About the no Google hits thing - probably a rebranded unit.

                              Sharp Lc-50UB30U may be locked out of Service Mode and Factory Mode
                              by RRice25541
                              So i got this tv from my neighbor, when it wasn't working right for him,, he purchased another tv and gave his old to me.
                              the color is all outa wack, like the settings have been corupted,
                              I've already done a firmware search using the wifi connection update from the tv and it didn't find any new update so it's got the most recent version.

                              so
                              The issue is i can't get into service mode or factory mode, tried resetiing it from user mode and it didn't change anything.
                              when i bring up the menu and type the pass codes to access either mode the menu disappears...

                              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
                              ...

                              [NOT A RESCUE BIOS] Dell Latitude E6530 Rare Factory BIOS (Revision A86)
                              by Amber TC
                              ⚠️ Not a Rescue BIOS. Flash at Your Own Risk. ⚠️

                              This is not A17.

                              This is not listed on Dell's support site.

                              This is an unreleased internal firmware revision recovered from a university loaner Latitude E6530... and it possibly bricked the system it came from.

                              It is from the 8 MB Winbond W25Q64 chip. Could be nothing burger but given the anomalies this is a very interesting firmware dump.

                              Firmware collectors and reverse engineers might find this useful, It contains certs, modules, and DXE drivers not present in A17. This is likely...

                              Dell XPS 13 9310 2-in-1 stuck in factory mode
                              by ancan
                              Hi,

                              I've got a XPS 13 9310 2-in-1 with what I assumed was a hardware error, but browsing this forum I see that people have gotten the same issue fixed with BIOS modifications.

                              Symptoms:
                              - Warning about factory mode at start
                              - Fans at 100%
                              - No service tag set, and when I set it in the BIOS it just reverts to blank.
                              - Shows 8AC6D992 on POST

                              I'd be grateful if someone had some tips for me. It's a nice machine and it would be a waste not to have it fixed.

                              Thanks...
