55LM8600 Screen blacked out!!! no picture at all. help!
So this is actually for my sister in law, who is pretty tech illiterate.
She msged me this morning saying that there was a problem with her TV (she got this tv per my recommendation).
She says she just turned the TV on as usual and was watching some stuff sourced off her laptop via vga connection as far as I know, and all of a sudden she noticed the screen darkening starting from one corner of the TV and it started to spread like black ink on white paper and it completely blacked out her screen.
Now it won't even show the LG logo when she turns the TV on.
The TV still has sounds and outputs sound coming from her laptop from the TV speakers, and shows power button all lit up and all that as well.
She says when she pushes functions like 3D, the screen would brighten up and all but still no picture whatsoever.
Doubting this is a connection issue as the Logo won't even show, so theres definitely no picture here.
I did my best to search up all issues related to this TV set and could not find any similar problems. Doesn't seem to be power or the mainboard, in fact, I just don't know what it might be. Backlight dead?
Anyhow, shes out of warranty I believe, they bought the TV slightly less than 1 and a half years back.
Any suggestions or anyone with similar issues that's been fixed?
TIA! Any help would be really appreciated.
