My backlight appears to have gone out. The green light at the top still blinks that I have a message and when I push the power button the 4 icons on the bottom light up. I can answer calls because I know where my unlock function is. What are my options at this point? Do I really have to replace my phone? Do people have luck getting them worked on for something like this?

Yes, the was bothering me for some time. I think the indicator is a little green light that blinks in the extreme upper left hand portion of the phone...not on screen, above it....but the blinking light may indicate a missed call or a voice mail is present.

Try this. Go into your phone icon, press and hold '1' and listen to any open messages. Delete each. Next go into your Call Log and delete all call history. Now exit.There should be no green light flashing in the upper left hand corner of phone. You have just cleared everything.

Next call your phone but hang up before leaving a message. Note the blinking green light in the upper left hand corner apparently indicating you missed a call. Go into your Call Log. It will say one missed call. Exit the call log and note that the blinking light is now off. You have acknowleged the call in the call log so the light goes off when you exit.

Call the phone again. This time leave a message. Note the blinking light again. Go into your call log again. Note the missed call. It would be nice if there was an icon or something HERE that indicates if this call left a voice message....but there does not appear to be. Exit again. This time note that the light continues to blink even though you entered the call log and acknowleged the call. I believe it continues to blink because you have a voice message. Exit.

Go into the call log again. Delete the missed call from the call hsitory. Exit. The light still blinks, I believe still indicating a voice message.

Go to your phone icone. Press '1' to check messages, delete the message and exit. The blinking is now gone.

So it appears a blinking green light indicates a missed call. If it still blinks after exiting the call log, you have a voice message.

If someone figures something else out let me know because this stinks!

Hello,
the error light sequence that you are seeing is indicating a "backlight error". Most likely you have a bad inverter board -the board that powers up the back-lights behind the display panel. They might be available via ebay if you are a DIYer, or you need to call for sony service.
Good Luck!

Cleaning or changing the pad is a messy project. This ink pad reset will reset the printer ink use conter to new status and your pad full message will be gone. This is a common occurance with Canon printers and the fix causes no harm. I reset my own MP470 about two years ago without incident.

This reset has been sucessful on many MP150 and simular units and should work on your MP170.
The second works on models with different control pads simular to theMP470.

It can be the power supply is sensing short circuits in the power supply itself or in the backlight inverter board, those are the two areas you need to inspect.

sounds like u have a bad mainboard.

The symbol for toner low is a box, without a top, with an arrow made of dots pointing up. Insert an new print cartriage.

knowing printer manufacturers I doubt they even have a sensor to detect that its full at all, they probably based on something crumby like print count. here are some instructions to reset the waste ink tank, the instructions vary so try them until one does the job :
