    LG 49UF680V: Fuzzy only NOT on settings

    HI all. I have never seen anything like this in my entire life. When powered on, you get the menu for setup. Perfect. After all that and not in menu, tv becomes fuzzy. Any pointers? Tcon or mainboard?

    Main board. I'd say corrupted flash memory. Maybe try a software update, failing that, new main board needed.
    Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

      +1 MAINBOARD

      This is the most common fault on all the UF series.
      LG should have recalled them all.

        Also I'd ad I got a working board for a 55uf860v exact same fault.

        Tried to keep the faulty board in circulation by swapping/copying the flash.

        Didn't work. Gave up.

          Sorry for late reply. Ive done a software update from the main menu but same. Guess I'll let the customer know. My spirit never took this one to even repair it lol.

            Elitebook 820 G3 engineering example: CMOS settings lost despite new cell
            by i440bx
            Hey there,

            I got a HP Elitebook 820 G3 Engineering Sample Laptop and I want to use it. Besides the difficult things at the ES-BIOS I have a big problem by saving the main BIOS settings.

            The laptop does not have a big battery because it was dead, but I already plugged in a new CMOS battery.

            It takes about 5min without power and the BIOS settings are lost. Unfortunatly I dont understand why the BIOS settings are only saved with power connected and this is the reason why I registered here.

            As written above, I plugged in a new CMOS cell and checked...

            Asus ROG Ally X -RC72LA - changed hidden bios settings with 'Smokeless-UMAF', won't get past boot logo
            by throwaway327
            ASUS ROG Ally X - (Handheld Gaming PC)
            Model No: RC72LA
            Serial No: SBNVKD001014459

            Hi all, I've spent the past week digging through the forums and guides to try correct my foolish mistake of changing hidden settings while tinkering around, and to be honest my heads overloaded so I'm hoping you'll be able to help.

            I used a tool called 'Smokeless-UMAF' to access usually hidden settings in the bios. I tweaked one or two 'safe' things but made the mistake of tweaking a lot of settings under 'USB/Thunderbolt Configurations' when I didn't know what they did. For...

            Problem with PANASONIC CF53 laptop after changing BIOS settings
            by AquaMan Ua
            Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in...

            Various Asus Motherboards losing bios settings
            by Billydv1@verizon.net
            Trying to track this down. 3 boards all same problem. Rampage IV Extreme, Z87 Pro, Z97 pro. All boot and function correctly but all lose bios and time settings if power is shut off. If power is maintained, sytrms boot and reboot normally. I have verified cmos battery is supplying 3v to board. 8 pin bios chip has continuity to ground but no voltage to vcc pin. I assume that's the pin that maintains the settings with power to bios chip. How do I track this down? What voltage do these bios chips require?

            Clevo W25CEW doesn't save Bios settings / shutdown issue
            by Conste
            Hello together,

            I have a Clevo W25CEW (Terra 1541) with some strange symptoms:

            1. I cannot save Bios settings by pressing "save settings" in the bios. By pressing "save & exit" it will save the settings.

            2. I can boot normally (UEFI installation), but when I shut the machine down and start it after a few seconds again it will show resume from hibernation and shutdown after POST, just before windows would boot. Then it will go back to factory settings and my UEFI installation will not boot!

            Already changed the CMOS battery...
