No matter What Video ... even in the boot up the Akai screen is scrambling.... Any Clues on what it could be... It just started doing it on its own.

I had the exact same problem already and my LCD is less than 8mo old. One of the techs from AKAI told me that its a known problem and many tv's were coming back "unserviceable". They now have a "supposed" fix for the problem. I only hope it really works and its not just a "carry-over" until the warranty ends. I am beginning to think its a quality issue and the units may just be defective. Thismay be thier way of doing a quick-fix vs. recalling all those tv's. This is what he gave me to as a solution to give the serviceman when he comes to fix the LCD.
AKAI model LCT42Z6TM: If there is no image or a badly distorted image with horizontal static lines, usually with four boxes in all four corners of the screen, there is a possible fix for this. There are four capacitors on the main board that have been identified as the primary cause of this symptom. Replace the capacitors at location numbers C280, C302, C320, C323 - 100UF 35 VOLTS [dxh]

I had the same corner squares/scrambled display problem in a set just over a year old (of course). It became completely unusuable and I was not looking forward to a repair bill of hundreds of dollars. After reading these posts, I opened the back of the set and took out the board with the connections on it. (FYI, the cable connections were all hot glued down, but this did not present a problem - a little wiggling and they came free. I also took lots of digital pictures to make sure I reconnected it correctly.) This board had the four capacitors (C280, etc) mentioned in this section. Since I have not had any experience with soldering on electronic boards, I found a friend of a friend who was a techie and he agreed to look at the board. He replaced the 4 mentioned capacitors - although he said they seemed to be fine. He did, however, also notice that capacitor C336 in the same area of the board was bulging so he replaced it. SUCCESS. The TV is again working fine.
So if you are reasonably handy with a screwdriver, taking out the board is easy and makes transportation a lot easier than taking the TV to someone. The cost of replacing a few capacitors on a board was minor, and in fact, if I hadn't found someone with electronic soldering experience, I would have given it a try myself. You may, however, want to check for bulging capacitors (indicating a problem) rather than just replacing the ones mentioned.

Try putting a fan on the back of the tv to see if it is getting better. If it does then you probally have a board that is overheating. If that is the case then CAREFULLY !!! remove the back and place where you can turn on and safely access the open back NO TOUCHING STUFF !!! Mabey lay it face down on a glass table or lay it on a table with 25% hanging over the edge to see the screen. Then take a COLD blow dryer and blow it on the boards to find out which one makes it get better. If one does then it will probally be your problem board. Make extremely sure that is the one before removing it by blowing from all angles on the boards around it without air hitting the suposed problem board. Then try a little hot air to see if that starts the problem on that board so you can be sure. Of course check the surrounding and offending board several times to be sure before removing.

I have not solved problem, although I paid you to solve it many months ago. The information I paid for was not the problem although the answer I was given was someone telling me it was for sure the problem.
