Question about Akai LCT2721AD 27 in. LCD Television

1 Answer

Set will not turn on.

For awhile I could get the set on by unpluging and repluging.
Now the standby light will only blink once , when I try to turn the set on, no matter what I do. Is this a big cost item?

Sounds like you have a bad power supply issue, and costs for repairs, and parts can start amounting with time and labor. If you could narrow it down by testing the power supply yourself with a volts/oms meter you will be able to tell a tech. exatly what needs to be replaced., or do it yourself.

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.

I would attempt to diognose these parts starting with power supply and moving forward to narrow your search from most likely and cheapest to more expensive and harder. You can also do visual checking while looking through the tv to see if their is any burn damage from a short cuircut.

Un plugging and re-plugging in the tv multiple times will take its toll on the tv and start wearing out parts needed to function. This is what leads me to belive it was power supply that failed or the on off controler board.

Good luck

I would look on e-bay for a broken Tv identical to yours, with the screen busted out and just put your screen into it. Easy fix and its only a few wires to reconnect when you have them both stripped down, that and a few screws.

Take photos if you dicide to go that route and use them for a refrence when installing and transfering parts from 1 tv to another. Makes your job easier and nothing will go forgetten and un plugged

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

Funai TV will not stay on. It turns on for 1 second and then turns off. Red standby light blinks on and of, what can I do?


Either the power driver board is faulty, or it has a humidity sensor in it, which turns it off. Move it to a very dry place for a few days, then try it again and it might work.

My Sony Bravia will play for less than a minute and then reverts to standy. Any suggestions?


Please unplug tv from wall socket for minute or so,, replug back in and turn it On.
If tv still goes to standby itself than its standby light would blink to show an error in somewhere inside tv circuits.
Let me know how many times standby red light blinking? There would be 3 seconds long pause in blinking so count pause to pause to determine problem section.
Thanks.

Sony Bravia KDL 46", no picture, standby light blinks 4 times


Since the TV is still receiving power, the problem is going to be with the TV's mainboard.  After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again?  The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation.  Don't forget to provide them the error code or 4 flashes repeating.
