Question about Akai LCT4216 42 in. LCD Television
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.

This works like a charm. "Replace the capacitors at location numbers C280, C302, C320, C323 - 100UF 35 VOLTS." I purchased the capacitors, cost me $1.07. Changed them all, that was the hardest part, took hours just to locate them. Burnt myself a few times, but by midnight, it was like new. So if you don't mind, doing something that would cost you over $500 by a profesional, I can assure you that this solution works. Email me if I can help, firstname.lastname@example.org.

I also did this repair last night, and voila....fixed. Strangely though, all the capacitors tested good, but one. It was reading 150 ufd, but, the changeing of the 4 caps did seem to fix the problem. Cost of the parts were 53 cents Canadian.
Thanks to Fixya and who ever posted the fix.
As a foot note.....AKAI Service has never responded to my warrenty claim by either email or phone. They suc the big kahuna.

I recently was given this TV because it was broken and did research on how to fix it on this website. When I turned the TV on it would show the AKAI logo with no problems but when the TV went to show picture it would show 4 boxes in the corners with a lot of colors and static. Taking the TV apart to get to the C280, C302, C320, C323 capacitors was easy. When I saw the capacitors they looked totally fine but decided to replace them anyways. I went to radio shack and got the capacitors for 1.40 each then jumped on you tube to see how to replace capacitors. The TV works great now. The job was easy and I would recommend the fix to anyone with a little skill with electronics.

Replacing the 35v 100u capacitors (5) works like a champ. Be careful when removing the glue as I had to replace a 3way resistor. Works like a champ!

I Replace the capacitors at location numbers C280, C302, C320, C323 - 100UF 35 VOLTS and my tv is now fixed. It was not obvious that any one of them was damaged until i had them all off the board then it was clear that one was bulging slightly on the bottom. Almost not noticeable until you take it off the board.
This isn't anything that challenging, it took more time to convince myself to do it then it the actual repair took. best of luck to anyone else.

Eerily similar symptoms as described by others here - a scrambled mess of horizontal multi-colored lines with faint to totally obscured video image in the background, and the 4 corner boxes flashing. Switching on and off worked to clear it up for a while but not for long.So, opened it up (lots of screws), replaced the four 100uF 35V capacitors at C280, C302, C320, and C323 with new ones (RadioShack part # 272-1028 at time of this post for $1.49 each), reassembled, powered up and BINGO perfect picture again on all input channels. I love the internet. Thanks to all of the great info for this fix to the ones before me.
UPDATE August 2016: The fix described above is still working. The AKAI HDTV is still working like new. Thanks again to all who contributed to this post!
