LG 47lw5600 Screen went blank while the sound and backlighting is still operational. danlajoie Posted on 2019-07-16 21:54:35 1080p LED TVs Vote Up0Vote Down

I was using my TV and notice when I turned the volume up the TV would shut off. I turned it off and the next time I turned my TV on there was back lighting and sound by no picture. I have seen on other sites that this might be due to a bad T-con board. The question is this a correct diagnosis and if so where can I buy a new T-con board.

I am having the same issue on my 60 inch TV.  This month there was a new firmware update.  I have been trying to figure out if it is hardware or software.

LG sells parts through Encompass. But mostly everything is discontinued!!!
