Which way should I plug in the cord for the front panel buttons?

Try changing the input device to something you are sure, works such as a DVD player.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

Yep, pull the plug. Power Cord, remove the battery, then press the Power Button and hold it for 15 seconds.

Next time you boot up go into the Control Panel and check your Power Options. You can set it to never hibernate.

Try unplugging the power cord and the PC cord for 2 minutes then plug the AC back in before connecting the PC. If that doesn't work, unplug the AC cord again and hold the power switch on the printer in while plugging the AC cord back in.If it doesn't work, try performing a semi-reset:

Remove both the cartridges and then perform the reset.

Perform a semi-full reset on your PSC 2200 by holding the button
combination given below, while plugging in the power cord.

CAUTION: A semi-full reset will reset or clear the following
information:

* Return the user settings to the factory defaults.
* Delete language and country settings on some models.
* Fax logs.
* Fax headers.
* Fax speed dial information.

Press and hold "#" and "6" buttons while on the front panel keypad,
plugging in the power cord.

Now insert the cartridges back. Try printing a test page from the printer itself now. If it's OK, it means that the printer is OK. If not, there could be a hardware problem with the printer.
Good luck!

Hello there,

Step 1: check all connections redoing them if needed mean remove the cables and plug everything back in .

Step 2: check the plug, plug something you know works into the plug to Test it

if the plug has power plug the TV back in and try the front panel button to turn on the TV if the TV still doesn't turn on let me know and we try a few more steps

Pull the power cord out and press the power button on the PC to drain the power for 10 seconds. Then plug the power cord back in and turn the computer on. If still does not work, then the power supply may be blown out and needs replacement.

try removing the front panel make sure the button isnt clogged with dust or disconected failing that it may well be your power supply internal fuse which can be repaird but a trick job if youare not very good with a soldering iron you may get a replacement one on ebay.

Please perform the following steps:

1. Unplug the power cord from the unit.
2. Press and hold OK and Cancel buttons together while plugging in the power cord back to the unit.
3. Turn on the unit.

If the issue persists, please replace the unit. From my experience repairing coast HP OfficeJet 7310xi is almost equal to the coast of a new printer.

Try these steps.
If Power supply light does not turn on (or no power supply LED)
Perform the following steps, in order, until power is restored or it is determined that there is a hardware failure:
NOTE: If the Power Supply fan spins when the PC is turned on but the light does not come on, it is possible the LED is defective. If this is the case, use the section Power supply light comes on or flashes .
1. Disconnect everything from the PC, including the power cord.
2. With the power cord disconnected, press the power button on the front of the computer. Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
3. Replace the power cord with another power cord, like the one used by the monitor.
Test to see if the computer can turn on. If not, continue using these steps.
4. Ensure that the voltage selector switch is on the correct setting, 115V for North America.
5. With the power cord removed, flip the red voltage selector switch to the opposite position, wait about five seconds, and then switch the red voltage selector switch back to its original location.
This ensures that the voltage switch is engaged and set correctly for your country/region.
6. Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
7. Plug a lamp into the same outlet to see if the wall outlet has power. Try the computer in a different outlet in order to eliminate the outlet as a possible source of the issue. Test both to see if the wall outlets have power.
8. Remove all extension cords, power strips, surge protectors and any converters that remove ground. Plug the power cable directly to the wall outlet. Test for power. If this fixes the issue, find the device that is causing the issue and do not use it.
9. Use a vacuum cleaner to remove the build-up of dust from the power supply fan vent holes. Make sure that the PC is turned off and that the power cord is plugged into a grounded outlet. Only use the end of the vacuum hose near the outside of the fan entrance.
Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
10. If all of the above steps have been tried and the power supply light remains off, use the steps in the next section, use the next section Power supply light comes on or flashes , to reseat the cables and check the power switch connector.

Try the following:

Check that power supply is plugged in to a live source.

Certain models had an additional power switch on the power supply itself. This would be located to the rear of the computer within 3-4 inches of where the power cord plugs in. Make sure it's on.

Press the power button on the front panel.

Press the space bar. The computer may be in sleep mode..

Gateway desktops usually have a small 'reset' button on the front panel. Press it.

If it still doesn't respond, I'd need to know a little more info before moving forward.

• Are there any lights lit? (K/B, front panel)
• Can you hear a fan?
• Does the monitor turn on?
• What (if anything) has changed since it worked last?
• What was the last thing you were working on?
  
• What model is it?
• What steps have you taken so far?

The flashing power switch and power supply LED on the rear in conjunction with a power failure or surge indicates that there is a defective component; typically the power supply, motherboard, memory, processor or modem. -Disconnect all the power supply leads, drives, and motherboard as well as any USB, firewire and other external devices. -Plug in the 115v power supply cable and look at he LED on the back of the power supply. If it is still flashing the power supply is bad and needs to be replaced. -If it isn?t flashing then unplug the power supply plug in one device, plug in the power cord and watch for the flashing LED again. If it?s flashing you?ve found your culprit, if not move on to the next component and repeat the process until you?ve found it. Don?t forget your plug in cards could also be the problem. Good luck and let us know if you have any other questions. As always please don?t forget to rate this posting.
