Continued Blinking Of LG 32LJ542D-TD Resolved By Software Reloading
This again was a TV attended to by me partially at my friend’s place. As there was continuous blinking and no display, first I thought it could be due to backlight problem. So, I opened the set and checked the backlight and found that one connector had come out and was glad that I was able to trace the fault quickly. My friend helped in soldering that side directly. But the blinking did not stop on further checking. The LED driver output was found normal and the LED strip also was ok when checked with backlight tester.
So, my friend suspected that the system might have entered into some error mode and tried to crack it by entering into service mode. But nothing worked. It looked like a software corruption. So, he removed the memory IC, loaded it into his programmer, read the program from his Lap Top, copied it to a safe place and reloaded fresh from his collection. Then replaced the memory IC back to the board. Well, the blinking stopped and the TV started working very well once again. Unfortunately, I could not cover the process as I was busy in dismantling another TV. But anyhow, these procedures are quite common and well explained in books published and listed in Jestine Yong’s blog. Here are a few pictures:
I assembled the TV back and allowed it to run as a test.
It worked perfectly well, adding satisfaction to its collection bag!
