Question about Akai LCT2721AD 27 in. LCD Television
Problem gets worse over a year or more, until the TV won't power on at all
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.
