All lights flash like crazy on powering up; diagnostic says "turn power off & on"
I have an HP aio 7710, actually, and today i unplugged it for awhile. when i plugged it back in (it plugs into a power strip that has a surge protector, btw), the display flashed up the normal "self-test" msg for a couple seconds, then all the LEDs went nutso, all flashing very rapidly, and the display said "turn power off, and on again." well, i tried that, but it wouldn't actually turn off--it would only repeat that same cycle again & again. i tried unplugging & replugging several times; same thing. is there any sort of "reset" button or procedure for this, or am i screwed? Thanks!

If a power surge didn't fry the mobo or PS, this can work: Unplug the tower from the 110 outlet, wait a couple of minutes, then plug it in again. Also try that with the power strip; unplug.. press its reset button, plug it back in.
1. Unplug the power cord from the back of the product. 2. Unplug the power cord from any surge protectors or power strips. 3. Select a wall outlet to plug the product into. Test the wall outlet by plugging another electric appliance, such as a lamp, into the wall outlet and turning it on. Unplug the test appliance. 4. Plug the power cord into the back of the product. 5. Plug the power cord into the wall outlet. 6. Press the Power button to turn the product on. 7.Now check if its already working.
If the HP All-in-One is turned off, press the On button to turn the unit on.
Unplug the power cord from the back of the HP All-in-One.
Wait 15 seconds.
Plug the power cord back into the HP All-in-One.
Turn on the HP All-in-One by pressing the On button.SOLUTION 2:
Reset the power module and test the power
Step one: Reset the power moduleThe power module has a safety feature inside that protects the product during a power surge. If you experienced a recent power surge, the power module might need to be reset. Use the following steps to reset the power module.
Unplug the power supply from the rear of the product.
Unplug the power cord from the electrical outlet, power strip, or surge protector.
If the product uses a power module with a detachable power cord, disconnect the cord from the power module.
Wait 15 seconds.
Reconnect the power cord to the power module.
Plug the power cord back into the electrical outlet. Do not use a power strip or surge protector.
Check to see if the power module has an LED.
If the power module does not have an LED, continue to the next step.
If the power module has an LED, check to see if the LED lights up.
If the LED does not light up, contact HP to replace the power module. To buy a compatible power module, right-click the following link, How to Buy HP , and then click Open in New Window .
If the LED lights up, continue to the next step.
Step two: Test the power on the All-in-OneFollow these steps to test the power on the product.
Reconnect the power supply to the rear of the product.
Press and quickly release the Power button ( ) to start a Power On/Off cycle. Do not hold the button down.
Not all power strips prevent power surge, only those that specify on their packaging or imprinted on them, that they are "surge protectors". Also, even these will have lost their surge protection once they have been hit either by lightning or a strong power surge. You would have to check with the manufacturer on how much of a hit they can withstand. Was there a thunderstorm in your area recently? Are you using a remote to try to change the channels? If so, try the buttons on the tv itself. Also try unplugging, waiting 15 or more seconds, plug it back in, directly to the wall socket. See if that resets it. If you still can't get it to change channels call the manufacturer of the tv, it may be a known problem and they may be able to help.
If your TV was plugged into a power strip with a surge arrestor, the power strip may need a reset (if there is a reset button) or replacement (those surge arrestors are only good for so many "hits". Try plugging the TV in elsewhere.
If it was not plugged into a surge suppressor, it is time to call a repairman.
The all-in-one product will not turn on
If the all-in-one will not turn on at all, follow the steps below in order to determine the cause:
Verify that there is power at the wall outlet.
Verify that the computer and the all-in-one product have a three-prong power plug.
Remove the product cable from any power strips or surge suppressors, and plug it directly into a grounded (three-prong) wall outlet.
For models that have an external power supply module, verify that the power supply module is plugged in correctly. Some power supply modules have a green LED built into the connector end or on the power supply module. This LED will be lit if power is present. If the LED is not lit, replace the power supply module.
Plug the power cord into a different electrical outlet.
If the all-in-one has an ADF with an external cable plugging into the back of the product:
Turn off the unit.
Unplug the power cable from the wall outlet.
Unplug the ADF cable from the back of the product.
Plug the ADF cable to the back of the product.
Plug in the power cable to the wall outlet, and turn on the power.
If no change, the problem is not the ADF.
If the problem clears, turn off the all-in-one, unplug the power cable, and plug in the ADF.
If the error returns, the ADF is defective. Contact HP Customer Care to get the ADF replaced.
Unplug the USB or parallel communication cable from the back of the all-in-one and try to power up the all-in-one. The computer may be grounding out through the communications cable. If this corrects the issue, check the grounding of the computer and outlet.
If the above steps did not resolve your issue, contact HP for additional issue verification or the servicing of your product.
I would try some simply things first.
1. Pull the power plug and wait for approximately 15 to 20 minutes before plugging back into outlet.
2. If your power plug is plugged in a power strip then try pluggin directly into the wall outlet.
3. I would make sure there are no paper jams.
4. If you recently installed ink cartridges, then check to make sure they are the right make and model for your printer.
Comments: If you had a power surge the printer may just need to be powered off for awhile. Some printers will hold there settings for at least 15 minutes.
