Re: panasonic no picture

did forget to say that all voltages from the power board are spot on

Re: panasonic no picture

Check the voltage on both sides of the tcon fuse - it's possible you got a bad one.

Re: panasonic no picture

checked and 12.1 on both sides

Re: panasonic no picture

MOST times the presence of audio implies the main board is functioning. Try reseating the LVDS cable on both ends and even the tcon->panel ribbons while you're at it.
