Question about HP PhotoSmart 7760 InkJet Printer

7760 Photosmart Red Flashing Light

When turned on after the green light comes on for a second, the light starts to "quick" flash red. And then nothing will work or print. Nothing comes on the screen. So why is the light flashing? Why is my printer not working?

Thanks

    When you press the power button the green light comes on, flashes 5-6 times and then it turns red, flickers rapidly and cannot be turned off (by the power button). Nothing comes up on the flip-up display. I have replaced the power supply but no change. I have reset the clutch as per instructions found on-line, bu no change. The ink cartridge carriage slides freely. Thanks in advance ~

    Update: both power supplies tested out good, so the problem is internal to the printer itself.

    I have tried every combination of unplugging, shutting down, reconnecting, powering up, PC connected, PC not connected, connected to the rear port, connected to the front port, different power supplies, different wall outlets, etc. etc. Nothing causes it to behave any differently.



    I have seen other electrical devices behave this way when there is a ground fault: is there any ground test or compoenent level test I could do to check for this ?



    Thanks again ~

My playstation has the light trun green yellow flashing red light


With your PS3 turned off, press and hold the Power button on the front of the PS3 for about 10 seconds (the system will beep as normal as it starts up but after 7-10 seconds it will beep again). The video settings should now be reverted. Doing this will also reset any theme settings. try this? seems to fix alot of issues.
