Well just a little update I put the replacement motherboard I bought offf e-bay in and it's working great now. It no longer shuts off every 3 mins like it did when I replaced the eeprom memory chip. So I would call this fixed. Now all I have to do is replace the psu as it makes a horrible buzzing sound that makes watching tv unbearable. And the one other issue is some of the led diffusers fell off so they will have to be re-glued but no big deal. Main problem fixed. thanks everyone.

Well I spoke a little to soon as it did power on and somewhat function but it kept turning off and freezing. It will display a image at least but like I said after 3 mins restart itself for no apparent reason. So it looks like a motherboard replacement is the only thing that will fix this tv at this point....

Well bholu was absolutely correct. I literally thought this wouldn't work but I bought a Winbond W25Q40CLSIP erased eeprom with no programming what so ever. I just got it today and soldered it in and really had low hopes of it fixing my issue. I soldered it in anyways thinking I have nothing to lose. Well when I turned the tv on after installing new eeprom it did the same thing smart logo then blank... turned it off and turned it back on and wouldn't you know it that it came alive right before my very eyes. What a great surprise. Thanks to all you guys for your help.

yea, I have a replacement 25q40 coming in the mail. The one guy said that it doesn't even need to be programmed which I find hard to believe. But yes I would much appreciate the firmware for that chip and I'm going to pick up this [URL="https://www.amazon.com/Organizer-Socket-Adpter-Programmer-CH341A/dp/B07R5LPTYM/ref=sr_1_3?crid=U0ZZAVAPIOG5&dib=eyJ2IjoiMSJ9.DayBBtmwEM4eNtpgqz5a7ZK3EmniNdaYeJMrtGjqwjbomN5UhT4k4PRcpdSh3s9mE_oMXM9Q1VqfYwOOV_I8CQaEdwk0tXZHsIWyhyqiLYx9UttjszjoekxB4ZSVp4D6POFr0ekcY7yGimLhlsXyl-E4bDuKtobCybNm9eAJH9YyppCDaIEWCN_PDys2-d3MiiPCzL2XlL7XDEgdtV0LpN_zkJ3DH7Jy4Zqz...

Ok tried all your steps other than I can't find a usb drive smaller than 4gb but the led didn't even flash for the usb drive once. I formatted it as fat and mbr and made sure to change how I put the file on the drive like you mentioned. I think I'm going to just put a replacement board in this tv and sell it on. Will keep everyone updated....

Froze the shit outta those both chips to no avail. Used almost a whole can freezing the whole board and nothing changed. Tv turns on displays the smart tv samsung logo and screen looks like it is on but no picture comes out and no visual. It then shuts off automatically after a minute....

Samsung/UN65H6300AF LOGO APPEARS AND SHUTS OFF
Hi as you can see from title, I have a samsung tv here that will show the smart tv logo and then no picture after that even hitting input or menu on remote and shows nothing but the backlight still appears to be on. The tv will turn itself off after a minute or so automatically. I'm somewhat confused if this is either a eeprom problem or a bad led strip problem. The power supply makes a pretty noticeable humming sound when it's turned on leading me to believe one of the leds are shorted but idk honestly. Any of you guys have any help for me? I have a good multi meter and can take pictures of whatever...4 Photos

Re: lg-55UH6090 Diffuser panel mixup
Ya I fixed this through days and days of giving up and restarting it. Their is no easy way of doing this other than trial and error and yes its a major pain in the ass. The school of hard knock taught me to never ever mix up tv diffuser layer ever again lul sorry man just keep trying different orientations.
