Picked up a Sylvania 40" LCD set for free, so I thought I'd give it a go for the heck of it
It's a model LC407SS1, and has a picture similar to this:

No audio, but I don't know if the menu settings are set on one of the HDMI ports or something. Pulled the back, and while the set is on, there is a peculiar ticking sound from the T-con board. Unplug the T-Con board, and the screen is black and even, ticking goes away. Might be in over my head, but the price of admission on this project is $0 so far
