In use or In stand by mode the blue light will flicker. It is a external signal on your computer that indicates that there are processes running on your computer harddrive.

It is not a problem.

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.

My matsui m32lw508 will not switch on just flickers then the standby light comes on.


Hello,

Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Take care .......

I have a Gigaworks 750, the Audio Pod is not working, however, there is power going to the subwoofer though the power light is flickering. Hope you can help me in solving the problem. Thanks


I did fix this problem and the whole bunch of other ones with the s750 system.

"light is flickering" is a very common! It shows that there is a problem with STANDBY power supply:

1) Yellow glue became conductive (needs to be completely removed)
2) Capacitor malfunctioning C61 (68uF 450)

3) mine had TH1 cracked (replaced from PC power supply) and D9 diode.

If this successfully fixed, you will be able to get 2nd stage power supply on (Relay or power on button)

If you will have problems there, there is a whole bunch of test needs to be done (capacitors, IRF740 etc.)

Samsung 55" flat panel lcd tv is not coming on the standby button light stayes on but no picture coming on it doesn't come on with the switch only by plugin it to the outlet.


Does the backlight come on? or even flash on and off when the TV is switched on? I presume the standby light is showing 'blue' then. Do you have any sound? Also, when the TV remote is pressed, does the standby light flicker?

Power supply is the place to look, look for bulging on top of the capacitors in the secondary side of the main power supply.
