    The on/off light on my HP Officejet Pro K550 blinks continuously. The printer does not print while this is going on, and the unit cannot be powered down unless the cord is disconnected or the powerstrip is turned off. When the printer is turned back on, it goes right into this mode again.

Red stand by light blinking continuously black screen

It cannot be reset fully unless it comes on and stays on (the model you have listed here.)

That set should have a blink error code--watch the red power light to see if blinking in a number sequence like 7blinks pause and repeats over and over.

I have a Mitsubishi WD-62525 HDTV that suddenly wont turn on. Just has a green blinking light when you hit the power button. Any ideas?

I found this on another website, most likely it is your power supply capacitors.
  1. Press the "reset" button and hold for 10 seconds .... Does TV turn on and blinking green light turn to solid green.

  2. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours..... Does blinking green light continue upon plugging in the TV.

  3. Disconnect ALL devices from the TV; DVD, Tuner, Cable Box, unplug the TV for various duration times .... Does blinking green light continues upon plugging in the TV.

  4. Press Power and Menu buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.

  5. Press Power and Display buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.

  6. Insure that no front panel buttons are inadvertently stuck in an "engaged" position.

Diagnosis: If none of the above test resolve the issue, then the failure lies in one of the following:

  1. DM Module Capacitors have FAILED.
  2. DM Module is defective.
  3. EEPROM Board failure
  4. Power Supply failure.

The led light blinks continuously and tv will not turn on

With the led blinking continuously it's probably a power supply problem. Unless you're a tech there's not much you could do other than unplug the power chord for a little while and plug it back in to see if there is a difference. If not you'll need a qualified tech.

Speaker phone light continually blinks

The blinking light on the speaker button means the forward when busy is on. To cancel it- With the handset on-hook dial #12.
Then press your own station number. Then dial # again. The speaker button should stop flickering.
Note: If the SPK button continues to flicker, Forward all is activated. It is the same process as above but use #11 instead of #12
