You said do the PDF, it doesn't have all the stuff on it like shown in the PDF. I did reset it, the panel type stays normal the model number doesn't change. Now no turn on. Gonna break it down again in a bit.
Thx all for now, I'll be back with updates laterComment

All settings
and the changes are stored in eeprom 24C512, if you can't start it, then move it from the old board.
But the native eeprom also stores its native keys, and these keys must correspond to the keys that are in the emmc.Last edited by lotas; 09-19-2024, 03:52 PM.Comment

Yep, it's not even annoying anymore it's just laughable how you are always correcting me and are SO wrong lotus.

I didn't export the value of the PDF. I was sitting in the service menu and it just shut off. I'm saying besides the panel value which I input, and did factory resets after. Nothing changed... And I never blame anyone here. All help is appreciated.
And lotas I may attempt that now that the board won't start.. will be a few days but I'll write back on hereComment

I figured this out. The solution was absolutely simple
You send a command to the TV with remote.
Press Info, settings, 3,1,4 then hit exit and unplug tv.
This does some screen correction command. Something I think many here will find useful.Attached Filesif you find these attachements useful please consider making a small donation to the site

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
I hope this is the right forum to post in despite not technically being a repair, but still a question of swapping boards.
I thought I'd explore the possibility to upgrade an existing working Samsung ue55nu7096u with the logic board (and power board if needed) of a newer model (ue55ru7105k) of the same size and appearance (and resolution). The reason being I'd like the extra inputs of that board including component in, an extra HDMI port and bluetooth. Its panel is broken so I have no use for the board otherwise.
The models launched in 2018 and 2019 respectively.... -

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....
