Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

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.

Standby light stays on and the tv will not go on


Please check batteries in remote that seems not working. Sony TV would either turns On or standby light will blinks if TV gets any internal problem.
You question shows standby light stays On that means TV does not receive power on command from remote.
If standby light is blinking in sequence, let me know how many times it is blinking and also intimate exact model number of TV to find out possible solution.
Thanks.

If blinks continue without any pause, the main board is faulty.
