Question about Akai LCT2715 27 in. LCD Television

1 Answer

Television will not fully power up to standby mode. Standby power indicator light repeatedly blinks in a weakish manner as if trying to fully turn on, along with simultaneously sync-ed popping noise, when rocker power switch is turned on. It is as if there is a shorted type voltage discharge (indicated by the standby LED indicators weak illumination in conjunction with a varying level of popping noise like a voltage spark amplified by the audio section) within the powering up capacitors. Could this be one of the smoothing capacitor cans? The powering levels could be described as a sawtooth pattern where it powers almost to full on status but quickly "pops" down to zero then re-powers and "pops' down again and again. Both indicator light and Audio popping sound repeatedly ramp up and down like this in a "POP"..."POP"..."POP" manner ~ one pop per 1/2 second.

It seems that your unit has some sort of Video side, PSU fault, or a problem to the Video section that is shutting down the Power Supply Unit, PSU. It is the sound that gives it away. This happens so that no further damage, and possible fire will occur. It is probably the PSU.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

Wont turn on red blinking light


How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy. For more information, check the link http://electronicshelponline.blogspot.com/. If the blinks continues, and non-stop, the fault should be with its main system control IC, and with the memory IC.

Power light blinking on nv53a gateway


Your Gateway laptop comes with a series of LED lights that alert you to the state of your computer. You'll notice there are blue, purple and red lights that either blink or display solidly. Each light, blinking or solid, has a different meaning. The blue blinking light on your laptop indicates that it is in Standby mode. Your laptop goes into Standby when you close its lid without shutting down the computer. To turn this light off, you'll need to take the computer out of Standby mode, and if you want to ensure that the blinking blue light does not return, shut down the computer after each use.

Open the lid of your Gateway laptop and press the power button. Once Windows loads, enter your password if required. The blue light will no longer be blinking because the computer is no longer in Standby mode. Shut the laptop off when you finish using it rather than simply closing the lid to stop the blue light from blinking again. Click "Start" from your Windows desktop and click "Shut down." Change your computer's power settings to keep if from going into Standby mode when you close the lid if you'd rather not shut down your computer every time you use it. Click "Start" and click "Control Panel." Click "System and Security" and then click "Power Options." Click "Choose what closing the lid does" from the list of options on the left side of the window. Select "Hibernate" from the drop-down lists under "On Battery" and "Plugged In." Click "Save Changes." Your laptop will now bypass Standby mode when you close the lid and it will enter Hibernate mode instead. Hope it helps.

Standby mode


Standby power supply runs 7/24 and this should indicate it is not allowing main power supply and hence the set to turn on= short someplace is most likely issue.

Sony TV LED & Blinking Codes - What Does It Mean When Standby/Timer Light Flashes

Sony has provided a "self-diagnosis function" with your TV, that in the case of abnormalities or problems the LED or red blinking light on the Timer/Standby indicator flashes a number of times to indicate the issue.
when there is trouble with your Sony Television set -- it indicates the issue in either the diagnostic mode, or even more commonly by flashing a series of LED blinks or flashes on the front of your television. Each set or frequency of the blinks indicates a very specific problem with the television itself.
Sorry but unless you may be able to repair the television set yourself , please call a local repair shop to the have a repairman sent out,,

Tv went off while watching a program power standby red light blinks 6 times then pauses then repeats tried unplugging unit waiting a few minutes then replugged same results nothing. can anyone help me ?...


Here's an excerpt from the Sony Manual online. And the link - http://esupport.sony.com/US/perl/webtree.pl?template=EN&mdl=KDF55XS955&content_id=68&category_id=11&problem_id=52

The POWER/STANDBY (red) indicator flashes three times
If your power/standby indicator is flashing in a pattern of three flashes, this may indicates that the lamp cover is not attached securely. Follow the directions in the Operating Manual under changing your lamp that related to closing and securing the Lamp Cover. Ensure that the Lamp Cover Door is securely fastened by tightening each screw.

The POWER/STANDBY (red) indicator flashes continously
If your power/standby indicator is flashing continuously, and the lamp cover has been secured, your TV may be in need of service.

The POWER/STANDBY indicator is lit up green (not flashing)
A sustained green light indicates your TV is on.

The POWER/STANDBY indicator is lit up red (not flashing)
A sustained red light from your power/standby indicator simply indicates that your TV is in standby mode. This shows you that your TV is ready to be turned on with the remote.

Is it the power light and not the lamp light? If the lamp light is flashing then replace the lamp.

Re: standby mode???


No really the standby mode dosent mean the sets fried or unrepairable. It just means that the sets in a shutdown mode till a power supply problem is corrected. They have shut down protection when the power supply dosent regulate the b+ and if it didnt shut down it would give off tons of X type radiation. thats just a safty on the set. seek a pro to assist you in repairing the set. Good Luck
