    I posted the common problem in order to answer it.....

    An older lady gave me FREE her 1 yr-old AKAI after enough frustration... She bought a new SONY.
    With my online research, I have found that there are MANY of these AKAI LCD TV's with the same power/green/red light problems, getting worse over time and finally won't power on at all (Phillips TV's too) ....
    I'm the furthest thing from an electronics expert, but I did the job slowly and carefully.  Assuming you have basic skills, soldering tools, confidence, concept of safety, I'd say you can too, IF your problem is identical to mine (failed capacitor or capacitors on the power supply circuit board).

    Here's my method (first time took me a maybe two hours; I could do the repair again in under 30 min.)
    Put down a very clean shaken towel and put the TV face down on a flat table or work area, so that the face stays protected.
    Remove the back slowly, paying attention and keeping the screws organized.
    On my set (AKAI LCT2721AD) the lower back portion (covering the speakers) needs to come off first, since it covers one of the screws holding the main back assembly.  
    One back screw will probably be under a safety/warranty warning sticker. Punch thru it, if you dare.
    For the built-in DVD player, remove the outermost two screws only (end cap), hinge it down and very gently pop the three tabs holding it in place.   This assembly stays with the TV.  You'll need to feed it thru the plastic opening as you remove the main back assembly.

    Next remove the power cable attachment (gently pinch and lift the connector) and unscrew the "ground" -small bolt on one of four corners of the power supply circuit board.  Note the circuit board is held by two bolts and two screws -- remember this.
    I decided not pull the circuit board connectors apart.  Turn the circuit board over, and get a good look at the capacitors (three 1000uf 16v in a row between the two heat sinks) ... they are likely visibly buldging, and needing replacement.  Look at ALL the capacitors for a bulging top popping up.
    Replace with higher temp. 105°c (I believe you won't find at Radio Shack) ... replace the 16v caps with 25v.
    Make note that there is a polarity to these capacitors - a negative side with a stripe on it. 

    Order capacitors online or go buy retail (could be wasted time and gas) .. decide if you prefer suction or braid wick to remove solder, and get your supplies together.
    Go to and watch videos! ... search: "solder" and "soldering" ... especially "How and WHY to solder correctly" <-- very helpful video.
    Practice your soldering with any circuit boards from the trash or recycling.. there's millions of items around-- I took apart an old dig clock.  Practice removing solder and components and resoldering with clean good results.

    I used to buy three electrolytic capacitors 1000uf, 25v, 105°c (the ones I replaced were 1000uf, 16v, 85°c) ... plus wick .. my grand total shipped to me in a couple days (regular first class mail) $7.52 !

    Good luck .. I hope your results are like mine!

    My TV worked for about 5 months, then gradually would not respond properly to a 'power-on'.

    Thank you so much, Ketch1! A friend gave me her "dead" Aiwa LCT2721AD(not
    Akai) and it had the same history. After about a year, ittook longer
    and longer to turn on, and finally it wouldn't turn on atall. I was
    guessing power supply and/or capacitors from thosesymptoms, and, with
    courage bolstered by your experience, I opened itup and replaced 4 caps
    that had mushroomed and vented. Theneverything worked fine!!! Thanks
    for pointing out the hiddenscrews. I noticed the TV and especially the
    power supply puts outa lot of heat. To try to prevent a recurrance, I
    screwed a 0.08amp 12 VDC box fan to the back of the TV to provide some
    extraventilation. That low power fan is completely silent.
    Thanks again - now I have a nice new TV!

  • ketch1 Apr 25, 2009

    You're welcome, CloneBoy ... It's cool to save hundreds, develop a new skill, and get a nice working tv out of the deal...  so many people toss tv's out of frustration... i'm casually browsing craiglists ads for such tv's which i could now probably fix.

    i've been warned by a wise friend/tech to be extremely careful with other capacitors! ... like the high-power beefy caps in musical instrument amplifiers ... some of these caps are big, like the size of a redbull can ... they can retain a charge and knock you on your *** if touched incorrectly or not discharged properly first.. i think i won't be messing with those!

    good idea with the mini fan!  i might do that.  any particular model or online source for ordering?

    Fixya ketch1 !

    That was the problem. I replaced 3 1000uF 25v capacitors and the tv worked like it should. Thanks for the solution to your own post!

    Years later this post saved me hundreds on my Akai TV. Followed directions exactly and TV is back up and running!

If the power supply is supplying the main board with the correct amount of volts, your controller board or your on off switch panel is malfunctioning and needs to be replaced. If its the whole board your looking at a few hundred unless you can find the same tv with a broken screen and just swap parts.The on/off switch board is cheaper but you have to remove alot of interior parts to access and becomes a hastle.
thank u rate me!!!

Just wanted to write a note to Ketch1 and the rest on this thread to confirm that this is an excellent solution to the problem. I followed Ketch1's advice and it worked perfectly. In my case, I opened the Akai flat screen and found the 3 capacitors and they were slightly bulged on top. Using a soldering iron, I removed enough solder to pull them out of the board. Interestingly, the 3 capacitors were 105 degree, 16V, 1000uF...not the 85 degree mentioned...I ordered 3 new 105 degree, 1000 uF, 24V capacitors from digikey. One thing that isn't mentioned here is that the 24V capacitors are larger than the 16V and don't fit quite as well on the board. However, even though they are touching and at a slightly odd angle (not straight up), they still work great. Hoping that this will last a while! Thanks again!

Ketch1 !! my hero. i registered here just to thank you! profusely! My set is a Westinghouse, but these different makes are more similar than different, with the same design flaw: underestimating the heat which makes capacitors fail. I checked out the youtube solder videos and practiced, but looking at my completed solder job, everyone would laugh! I ****! But you know what, the connections are soldered solidly (yet sloppy) and now it's all reassembled and working perfectly!! Truth is, most of us are just normal dorks evaluating whether we are skilled enough to tackle do-it-yourself repairs without screwing it up! This was a big success story, thanks to the Internet, and cool cats who help others! Now, ketch1, about my GE washer.... haha

The solution above by ketch1 was 100% spot-on. Thank goodness there are people out there who are kind enough to share this information. 95% of the people in the world would have taken that Akai TV and tossed it to the curb. Thanks for saving me a ton of money, and helping me to better understand just how simple it is to make basic electronics repairs.

My Vizio Tv won't turn on

The power supply regulator board shouldbe ckecked for fault. Check the fuse. If it is found burned out, find the reson for that. Surely there will be a reson for blowing of the fuse, if it is blown up. Without rectfying it, inserting an other fuse in place, might make things more worse.

My vizio tv keeps shutting off

If it turns on reliably but won't stay on, try putting a portable fan pointed at the rear of the set.
If this prolongs operation, it may be a semiconductor at fault or an early warning of a common problem caused by chemical (electrolytic) capacitors going bad in the switched mode power supply.If this is the case, the problem will continue to get worse until it no longer turns on at all.

TV will not turn on and stay on when turned on. I have a ViewSonic 4060w LCD TV Is there a battery on the TV that needs to be replaced? I have unplugged and repluggehald TV. What can I do? I have to...

iF THE SET is a year or even two old and you have to repeatedly turn it on and on but once it is on it is ok, the problem is in the set's power supply.

All of these sets (every brand) have a "standby Power supply" built into them, it runs 7/24 even if the set is not turned on. One of the areas some companies cut corners on is the filter capacitors in this part of the set: Say the constant voltage is 9 volts and they use 10 volt rated caps, the caps will fail after a year or two from heat.

The reason companies do this is the cost difference say on 10,000 sets between 10 volt versus 16 volt rated caps is a nice piece of money.

If someone opens it and follows the power cord to the supply it will be easy to see, these caps (see photo) have a perfectly flat silver top with creases---any caps puffed up are bad.

Look at the caps and Before you rate this information let me know what you find, this problem will not just go away and usually gets worse and worse until the unit will not turn on at all.

XBR 4 vertical black band, ghosting/smearing, getting worse.

Hi, I have a similar issue which is progressively getting worse. My TV is on a sliding mount, and interestingly enough, sometimes I can "jilt" it by hitting it and it clears. This seems to me to be a connector problem, where heat (thermal expansions, electrical resistances) can introduce degrading signal. Now if I could find a manual on how to take this damn thing apart.......Certainly does't solve the warranty issue, but at least gives a reason for one to kick their TV.

Wont power on after being turned off, but if unplugged and replugged it will.

It looks like the power supply is not providing the correct voltages to the other circuitry and that is when the LCDs failed to power up. In about 95% of the time the power up issues are due to a defective power supply.
I repair these power supplies, let me know if you required further assistance or you can email for more info.

Plan on fixing or replacing the power board soon. It will keep getting worse until, the end. There is a small bright side. It is the best damage to sell your broken tv "as-is" online. Someone will come pick it for sure.
