Does anyone know how to rollback the firmware in an LG TV without using the screen on the TV? I need to rollback the firmware but can't see the menus to change the DNS to fake it into to a downgrade.
Is it because you installed a Wrong F/W in the first place--maybe looking for additional features that chassis did not come issued with....?
(Seems endemic--Ive seen a few sets lately that have been 'Upgraded'--And Bricked in the process--Never ends good after that....)
Only proper way is to pull the EEPROM and re-load with a flash-tool with the Correct F/W if you can get it, Not easy or quick as it'll be a SMD device.

I am actually trying to use the board for another TV. They changed the firmware for one model. If I can revert the firmware I would be able to use this board in another TV that doesn't have a panel short.
Thanks for assuming I installed the incorrect firmware for this board.
What I need is a list of command to use and a way to get into these prompts for then TV in a linux platform.
I am thinking of using something from openLG to allow me to modify the firmware in a power only environment.
Yes I have the TV connected VIA RS232 Serial to USB
If anyone can get me some advise on a script or program to use for LG TV's that would be helpful.
The TV functions properly including the remote and sound. The only problem is the LCD panel is shorted on both sides and I can get a screen to come up to downgrade the software using other methods like DNS changing and faking it into think there is an upgrade.
Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...
I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...
Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...

Does anyone downgrade the firmware?
The firmware is like EC - BIOS reprogramming? or I can use other methods ...
Just had a customer bring in a HP 14s-fq1010nm to do some maintenance.
After updating the BIOS to the latest (F.35) I get black screen (no backlight turning on). However the backlight turns on if I connect an external display to HDMI, but when booting to Windows, both displays remain black.
After disconnecting internal LCD, and plugging in external display via HDMI, it works on external.
I tried downgrading it using official method - using an USB drive with older BIOS version, but it fails, saying that the BIOS files are corrupted. I used about 5 different older BIOS versions...
