Tv turns on, backlights on but no picture, sound is present. Responds to remote, mute, voll up/down etc..
On initial power up the red led comes on solid, then switch on red led blinks 17 times. After initial power on from stby to on theres just 4 red blinks. (just for info really).

So, apart from the ana pin I guess these all look good?
Theres no obvious damage on either side of any of the boards and appear to be getting various voltages that look good around the main board and getting 12v, 1.2v & 1.8v on the T-con.
Theres a very, very faint 4 inch wide vertical bar around the middle of the screen which lines up with one of the tabs so its possible even if the tv can be fixed there will be bigger issues ahead, tab bond fault!
