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?

Re: LG 49UF680V: Fuzzy only NOT on settings
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.Last edited by Hamie; 07-29-2017, 04:46 PM.Comment

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.Comment

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... -

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... -
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... -
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? -
I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).
