    scrambled squares in all 4 corners of screen display also scrambled and when i do get a pic thin white lines running across the screen seems when i turn it on and off several times i get some results but it is getting worse....................... ME TOO, DUDE! Exactly the same problem. What the heck IS this? How do I fix it without sending it in?

  • ltlyon Dec 25, 2007

    Same problem here except it only does that when I turn to High Def and only once in a while. It will go away if I turn it off for a few minutes.

  • tooty74 Dec 28, 2007

    I'm having the same problem. One of the techs at Akai Tech support says its a problem with this Akai model and many units were being sent back "unserviceable". He gave me this information to give to the repairman when he comes out to fix it. I only wonder if this is just a "temporary fix" to cover the bad quality of this product. My LCD is less than 8months old, luckily its still under warranty.




    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 have experienced the same problem which has gradually gotten worse.
    At first the problem would go away if I let the set warm up for 15-20
    minutes and then cycle the power off and on. Now it takes around 40-45
    minutes. It also seems worse when using it with the higher resolution
    HDMI input. Yesterday the picture was completely gone.I'm still under
    warranty so I put a call in to Akai for service. Still have not heard
    back from them.

  • spotsky Jan 09, 2008

    Akai LCT42Z6TM malfunctioning with small shooting white lines, then total horizontal lines with small boxes in the corners. I have to turn it off and on for about 30 min, before the picture stays on. This has happened within one year of purchase, and I have contacted akai but there has been no responce.

  • Kimvor Feb 07, 2008

    I purchased the same tv & have the exact same problems. Contacted Akai 1/8/08, FINALLY called them back for the 10th time this evening & got a telephone number for a repairman. Calling repairman 1st thing in the morning. My tv is less than 4mo. old. Anxious to hear if anyone has gotten this problem resolved. Akai evidently has horrendous customer service!

  • Gerbers Feb 11, 2008

    Had the same problem as you are reporting, where Hi-Def signals would give me the most trouble. The condition kept getting worse and worse to where I was unable to view anything in HD over either the HDMI or Component inputs.

    I first contacted Akai Customer Service on 12\21\07 (the set was only 7 months old). The complete lack of customer service I have received is sickening. I have never been contacted by them in the last 8 weeks, I would always call them. After about 7 weeks of calling, they informed me that they could not find an authorized service shop in my area (I live in Minneapolis), and that they would be replacing the set. I was informed on 2/8/2008 that the replacement process could take an additional 4-6 weeks. This, combined with the fact that I had no confidence that the replacement would be of any different quality than the original set, forced my hand. I went back to the store I had purchased my set from (Sam's Club) and plead my case. They agreed to exchange my set, and I replaced it with a new 42" JVC on Saturday.

    Buyer beware, Akai might make good products from time to time, but if they ship you a defect, you will be frustrated for months trying to resolve the issue. In the end, I would have to say it isn't worth the chance.

  • MrBill17 Feb 26, 2008

    AKAI finally came through after about a month and a half. I fortunate to have an AKAI service rep just a few miles from my house. Once my warranty was verified (I had to fax a receipt to AKAI) the rep came to the house picked it up and returned it in two days. He said he replaced several capacitors as was suggested in an earlier post. It's been about a month now and the set is still working fine. I agree AKAI is very slow in responding so you have to be persistent.

  • Anonymous Jul 28, 2008

    I have exactly the same problems with the white lines that happen more and more quickly over time after warming up. I have not yet solved it. 

  • sajjon Sep 14, 2008

    same as above post. Horizontal white lines or multiple colors and no image in the background. Color behind white lines ranges from black/blue/green/pink. If i leave the monitor on for about an hour and restart the problem goes away. Problem was correctable by switching on and off a couple times when problem was first apparent but now requires at least 40 minutes of warmup to correct, and longer every week.

  • katenassau Sep 29, 2008

    Same problem, same TV, no support from AKAI just the run around. We live in Ontario and they claim to have no authorized technicians in this area. We've been calling them for about 2 1/2 months now. The tv is not even a year old, squares in the corners. At first we would turn it on and off and it would eventually correct itself, however now it's about a 1 hour long process of turning it off and on and we eventually give up. Any suggestions on how to get help from this company, they don't seem to care.

    I had seen this problem several times. If you have the white lines and they go away after it warms up. and you have to turn it off and on and it seems to be getting worse, you kust replace the caps or your set will stop working at some point soon. If you need help email me at tommy@ruden1.com

  • VinAiz Apr 09, 2009

    I have teh exact problem with the unit bought from Sam's club. It seems the replacement of the capacitor is the solution. I am going to try and see if I solve it. Vinny

  • Anonymous Apr 11, 2009

    Started with vertical lines on the screen until TV was on for 20-30 minutes. Now have screen blurred with 4 boxes in 4 corners and then vertical lines on screen. Turned TV On and Off it helps some, usually just have to wait.



    Some have mentioned replacing the 4 capacitors. Can it be done easily, any tips on doing this repair, where do you purchase the capacitors, and are the capacitors all the same?

    Thanks for your help.

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, csclarke@gmail.com.

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!

Posted on Oct 14, 2009

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!

    I will add that the four capacitor sockets - C280, C302, C320, C323 - are grouped near each other, all within about a 2 square inch area near the upper left-hand corner of the board.

We have a 50" Vizio plasma TV with a persistent blue, sometimes white, pair of vertical lines on the right side about 1/4 from the right edge.


if those problems were present when you got it back from repair, then, the guy didn't fix it fully.

if those are new problems - then you are now finding out why electronics and plasma displays wear out after ten years, replace the unit, don't pay to 'get it fixed' as the rest of the parts are old and about to also fail.

You may have bad capacitors on the main board where the signal is processed. These caps are as labeled: c280,c323,c302 and c320- replace this one first (it usually fixes the problem) Replace these caps with 100uf @35V

Akai LCT42Z6TN


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]
