I replaced the LED Driver board but that did not help. I have sound, but no image. When I turn the TV on, no LG sign, nothing.
LED strip has failed bad enough (e.g. LED burning open) resulting in power supply over-voltage or under-voltage protection kicking in.
Solution is to open the LCD panel and replace strips, preferably all of them with new, though some techs would only patch/fix the bad ones.
It's not something I'd recommend doing for first time on a 60'' TV.
It's not a rocket science, but has its traps and if you want to see that TV working bring it to someone local who does that.
Alas it's one of the things that can't be serviced remotely, like a main board, for example, which you can send to someone and have it repaired.
Testimonial: "Issue was with the T-Con board. Part V12 60FHD. Installed new board from Amazon and TV is working fine now."

Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.
