AKAI LCT2721AD On/Off Problem

I have an AKAI LCT2721AD LCD Flat Panel just over a year old. A few weeks ago, my roommate tried to turn the TV off using the side button, and felt a shock from the TV. Since then, any time the TV is plugged in, it will constantly turn on and off. It will actually run the entire startup sequence, including showing the current channel and checking the built-in DVD player, but then immediately turns off once it boots up, and back on again, etc. It is possible to change channels, sounds, etc. just before the it turns back off again. Any ideas? Thanks a lot!

Well, I have the exact problem. There's a 'free' solution that's worked so far... my understanding of the circuitry is limited, but all I did was I stuck the ends of a black rubber twistie tie (the kind that usually ties down bread bags, or you might be using to tire your wiring, etc.) into one of the side buttons. The idea is to keep one of the side buttons depressed. If you hold down one of the buttons, you should be able to use the remote to turn on, change source, input channel, etc.

My Philips LCD TV had the same problem. If your Voltage system is 110 AC till 127 AC and no transformator, then it is probably caused by one of the 4 main transistors, which are likely not originalfrom AKAI, but made in Malaysia or closeby there.
My TV works perfectly after 1. Replacing the burned or semi-burend transistors (in the back panel) 2. After repair (=US 60 plug the TV in a outlet from transformator set to 100 V.Good Luck!

Akai TV remote is not working correctly


I don't think the Akai remote is designed to work with cable or satellite service. I have to use both remotes & I have Direct TV.

Try unplugging the TV for a few minutes then plug it in and try the remote again. I had the same problem shortly before my Akai LCT2721AD quit working altogether. Three 1000uF capacitors blew in the power supply. Bought 3 new ones and replaced the blown ones myself rather than pay over $100 for a new power supply. Works fine now.

Tv will not turn on with or without remote


The power supply is broken. You need to replace the capacitors that are bulging inside. I did and now it works fine. I don't have any experience but I did it. Follow what this guy did. http://www.fixya.com/support/t1661054-akai_lcd_tv_power_light_stays_red_turn

TV turns itself off after turning on. TV screen goes black.


Based on what I have read AKAI has reoccurring problems with power supply and bad DVD sound. The problem you have is caused by the DVD player trying to start. Never leave a disk in when you shut it off or you will have the same symptom you are describing.

Hello genetics2003,

I think that this is a power supply problem. I would suggest that you get a qualified TV technician to troubleshoot this issue.

I hope this helps

Mine does this all the time. It appears to be a factory flaw. The only way around it is to set the channel you are watching to "MONO" and the crackling sound will disappear.
