Hi Robert,
This appears to be case of dirty ribbon and connector between the TCON board and the LCD panel.The ribbon or flat cable and its connector on the defective side between the TCON and the panel has to be cleaned thoroughly. If you can not do it yourself, any good tv Tech. should be able to do it for you.
Good luck.

ok I have ran across this before.. First turn on the TV and go to a channel u know is good, with sound.. now turn off lights in the room.. or just darken the room.. next take a FLASHLIGHT and turn it on and shine it into the front of TV . If u see the images on the screen when moving the flashlight around. that is a good sign.. That usually means the Backlight board or boards are not working..with the TV on and in a darken room you should be able to see light coming through some of the Vent holes in the back cover, that means the Backlight board is working. from what u say I would bet on the backlight boards. pretty easy fix.. Unplug from the AC outlet. remove the back. Now be careful back there cause u can still get Zapped. I ALWAYS take pictures of the back (close up of the model and serial #'s) I take several pictures of the inside of the TV. some TV's have the Backlight board or boards on the side of the screen and some have the backlight inverter built in the main board, since u have already replace the main board u must have backlights separated. . Take close up shots of the board, and write down all the #'s from the board and when u order make sure u order the exact one..I never remove the bad board till I have the new one ready to install. I always go to ShopJimmy.com first to see if they have the part. Then I check Amazon, and then eBay. in that order.try to buy NEW boards if u can.. Hope this helps.

on some TV's the Analog board is where the other cables plug into. I know on a Sanyo I am working it looks like the analog and main digital board are all the same. but they are just hooked together. I bought an analog board for less that $30 from Shop Jimmy.com. The prices might vary according to the make and model of TV. need to be careful and remove the back of the TV . and get the part # directly off the board. BE SURE TO UNPLUG from the wall outlet first. Nearly all the boards carry a charge even when unplugged so be careful.

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.

First of all check the power cable is connected to both the TV and power outlet correctly and that no fuses are blown.

What are the symptoms of the set? A defective power supply can mimic symptoms of a bad main board

No, your video and audio processing should take place on the same main board.

Are you needing a replacement?

In order to ensure, it is not caused by the input device, connect a DVD player and see. Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
If problem persists, I suggest it is better to refer it to a qualified service technician, since the back cover has to be opened for investigation/rectification.
