    I can see the back lite is on... but there is no video...only audio. Tried the DVD input - same thing... I have it opened up... Looks like the Video input board (where the inputs attach into) might be the cause). I'm searching on here for any clues (usually a solder joint skip on a particular a video processor...but need the schematic).

Try calling up a Menu for Picture on the screen with your remote.  Also check that it operates the TV and not the VCR or DVD player.
Good luck.

I have a panasonic LCD tv i could hear the audio but i can't see the image of the tv can someone tell me what could be the issue of the tv?

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
Some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

That will be real expensive repair jobs, it can be from the power supply or from the backlight inverter circiuts. I would leave it unplugged.
It will cost too much to have it done at the repair shop, it is only 4:3 screen also. You may want to think about it first.
