Chosen Solution

LG TV stuck on reboot loop after successful update. model : 22lk3300-TH after update the TV rebooted automatically but then showed LG LOGO screen for about half a second followed by a black screen for about 12 seconds and then reboots again. this reboot loop never stops as long as it is connected to power line. it is obvious that it need to be reprogrammed again but all methods need the TV to be booted properly before rollback or reinstalling the firmware again. i have RS232 cable connected to my PC but yet i could not use terminal emulators to connect to the TV. is there any way to flash its ROM ? (except buying a new mainboard)

sure that depends on that? I have the same problem and in the internet seems a known problem, caused by power board (bad). Now they are building TVs for a little longer than 2 years, and LG has done well

The same thing happened to me. Did you find a solution?
