When the power is off, I can see the red light on bottom left, but when I turn it on why do I get nothing, no picture, sound or anything?


The red light indicates power is getting to your TV and it is in "standby". When you turn your TV on, an open internal fuse or power supply failure may be preventing normal operation.

Won't start up


Either power or logic board problem. If it chimes but does not boot and the screen lights up then it is a good sign. Will it do anything?

If does nothing try a different power supply first.

Try removing battery and disconnecting power supply, then try to start it without battery and just power supply.

then try charging the battery overnight. If the lights on the battery show any charge after a few hours with it plugged in and the computer turned off, try letting it charge overnight and then try starting it without power supply connected. If none of these thigs help, I would have to look at it.

My printer will not turn on


First, try pressing and quickly releasing the Power button to start a Power On/Off cycle. Do not hold down the button. If this resolves the problem your done; if not continue on.

Inspect the power cord for visible damage; if damaged will need to contact HP to replace.

Disconnect the power supply (power module and cord) from the power source (wall socket) and the printer.

Test the power source, wall socket with or without your power bar or surge protector in place, with a small appliance you know works to confirm you have power. You may want to test the wall socket first and then test the power bar, etc. to make sure each component is not the problem.

If the appliance works then need to investigate the power supply. If the small appliance does not work you may need to check your electrical panel for a tripped breaker and possibly consult an electrician to check your electrical wiring.

To test the power supply plug in to the working power source; if the green light on the power supply does not light up you will need to contact HP to replace the power supply.

If the green light on the power supply lights up; reconnect to the printer.

Press and quickly release the Power button to turn the printer on. if the printer does not turn on you will need to check the USB cable.

Disconnect the USB cable from the printer.

Press the Power button to turn on the printer; if the printer turns on you will need to replace the USB cable.

If printer does not turn on, check the battery if your printer has one. A red light means the battery requires recharging; if it is still red after recharging, replace the battery.

If none of these steps resolve your issue before replacing the power supply try plugging the power supply directly in to a different working wall socket with no power bar or surge suppressor.; Press the power button.

If still no power to the printer you need to replace the power supply.

My epson Lx-300+ printer is not turning on even though it is plug on the computer and in the electricity. I turn the switch of the printer but it doesn't work. There's no paper jam or anything in the...


This is power failure. No need to find out anything what is the problem of your printer. Just send it to anyone very near to you and repair your printer.
I have printer like this and the problem as the same of yours.
No power, no light or even initial to run the printer. My technician says that it's power supply defective due to high voltage electricity.
Or I'm sure also its fuse problem.
Hope this tip might help you.
Good luck!

Hp photosmart c4580 won't print


Your problem indicates that your printer is not getting the power supply .

  • Check the power cord for any physical damage. If the power cord is damaged, replace the power cord.

  • If the power cord is not damaged, plug the power cord into a different electrical outlet without using a surge protector. The product power light should turn on.

  • If the product power light does not turn on, the power cord should be replaced.

DVD player froze, now only turns off


Sounds like the power supply in the dvd player has failed. It works just well enough to turn on the led infront but as soon as you go to do anything it shuts off. This is common in cheaper dvd players. Unless you can troubleshoot electronics. Or know someone that can. Your best bet is to unplug the unit and disassemly and retrieve your dvd.
