Technician's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The TV Technician I'm going to connect you with knows all the tricks and shortcuts. Is there anything else important you think the TV Technician should know?

I think that one of my kids slammed a drink down and a drop wend down the front near remote sensor we noticed a few faint lines at first that made it look like we were watching ntsc in pal then it eventually went off
Customer reply replied 2 years ago
That's my theory anyway think I saw a tiny drop of liquid in inner casing when I opened it
TV Technician: Pete, Electronic Engineer replied 2 years ago

If any liquid has got near the panel itself then it could be fried :\

I'm not100 percent that's what happened
TV Technician: Pete, Electronic Engineer replied 2 years ago

It seems you have already tried replacing all of the main boards that could cause this problem, so I'll check if the other experts can offer any further input on this.

Hello and sorry you're having problems. Upon reading everything you've posted here, this indicates a bad LED panel in the TV, which is not replaceable- since the panel costs 80% of what the TV cost when new, and are not sold by the manufacturer aside from purchasing a new TV. The T-con, Mainboard and Power Supply have all been replaced and your panel is still not producing any images- so unfortunately this does tell us with certainty that the panel itself in the TV is faulty, and unfortunately, aside from purchasing the exact same model number TV, used, or with a different fault and taking the panel out of that set- this is not a repairable fault.
