Another nice fix well done. Sometimes the major Engineers can't see the wood for the trees and give the wrong advice. Like you say, the panel numbers must match.
Brilliant Allen, you do pass on some wonderful tips to us all. Keep up the excellent videos please can never get fed up of watching your amazing uploads. Very informative in deed. Regards, Brian 👍👏🏴👍👏🏴
Bit late now but you couod swap the eeproms over from the new board to the faulty one a see if it works. Then read the working eeprom and reprogram the faulty EEPROM. Probably not an initially cheap,excer ose but you could end up with working spare boards
The thing that bothers me about new TV screens, no matter how expensive they are, is that the sound is incredibly bad. Yes, just buy a soundbar. The problem with that is that MANY screens sit so low that the soundbar will cover the bottom part of the screen. On the LG OLED, the foot sticks out so it is in the way. It is not possible to have a sound bar in front of the screen! Are TV factories idiots and don't understand anything?
Foxconn bought a majority stake in UMC back in 2016, no doubt mainboard design/manufacture is done in China. UMC just screws all the imported parts together in Poland. Hands-on experience is all sluggish, buggy junk, even when new. At least if they use common LG screens those could be used to fix faulty/cracked Vestel's.
Hi Allen it’s got UMC Poland on the label, the sharp tvs are awkward as some of the units use infa-red remotes and some are RF remotes, I do the same as you as long is the screen is the same you will be fine, that’s a RF Remote
FIRWARE ABOVE SHOULD FIX IT,. faulty uboot , bootloader in flash failed. power smoothing caps fail as in this video, to clean power to flash ic,, which in turn causes corruption,in main flash.. to replace caps, and flash main flash ic,, i use RT809 ..
Hi, how easy is it to change Cold Cathode Fluorescent Lamps (CCFL) on a 52 inch lcd screen? And how easy and safe is it to send such things by post? Samsung LE52B620 Is 45 inches the limit? Do you have to use special suction cups to lift up the LCD panel itself?
Did you try to read the flash chips firmware from the bought working one and copy/write it to the faulty one? I think its the 8 leg chip in the middle.

I recently repaired a Technika (UMC) set by purchasing a pre-programmed for the model NAND chip off Ebay.

Engineer's doing smarter things with their knowledge. No one will study 10 year's to fix other people junk

Samsung LE52B620
Is 45 inches the limit?
Do you have to use special suction cups to lift up the LCD panel itself?
Hi - could you upload the .bin file from the new board using UART pins?
I have a sharp tv but it is an older lcd made in japan a 32 inch .

@@da_chriss8879 No it’s not that anymore. It used to be. These are on the flash team on the right.
Firmware gets corrupted by bad hardware ie the caps.
@@andythomas7931 Yes the caps cause this
