I get a message that says "Waste Ink Near Full".


3 choices are available. Take it in for service(expensive), try to clean waste ink pad yourself(messy) or try this reset yourself. It works on many different models and may be your answer.

I have been running my printer for approximately 2 years since resetting mine without a problem.



Waste ink full reset


These are the instructions which worked for me on my Canon pixma mp470:

1) Close the print head cover, and turn off the printer. While pressing the Resume/Cancel button, press the Power button. (Do not release the buttons. The LED lights in green to indicate that a function is selectable.)

2) While holding the Power button, release the Resume/Cancel button. (Do not release the Power button.)

3) While holding the Power button, press the Resume/Cancel button three times, and then release the Power and Resume/Cancel buttons. (Each time the Resume/Cancel button is pressed, the LED lights alternately in either orange or green, starting with orange.) During initialization, the LED blinks in green.

4) When the LED stops blinking and lights in green, press the Resume/Cancel button the 4 times. (Each time the Resume/Cancel button is pressed, the LED lights alternately in either orange or green, starting with orange.)

5) Press the Power button. The LED lights in green, and the
selected function is performed. (When the operation completes, the printer returns to the menu selection mode automatically.)

6) Power off then back on and test.

TV has been working great for the past 6 years, this morning when turning on the TV nothing happens except the standby light flashes about 9 times on and off. No click like I usually hear when turning on...


Hi Dave,

We have had this same problem twice now - the first time under warranty (no problem) and now currently. The 9-blink error code refers to needing to replace two diodes on the G board. Specifically, D6301 and D6116.

The warranty time, the repair guy came and resoldered the new diodes onto the G Board, reinstalled the board, and was on his way. We had no problems for the next 3 years.

THIS time I ordered the two diodes from Andrews Electronics (www.andrewselectronics.com) am removing the G board myself and taking JUST THE BOARD to a local TV repair guy. This is a LOT cheaper than calling Sears or taking the whole TV to the repair guy. Here are the links to the specific diodes:

D6301 - http://parts.andrewselectronics.com/search/electronic-parts/parts/7/6-500-567-21.aspx

D6116 - http://parts.andrewselectronics.com/search/electronic-parts/parts/7/8-719-081-97.aspx

They are a heck of a lot less expensive than other places and the customer service I received was great!

I hope this helps!!

2 red lights are blinking!!!!!


is both the light blink the same time or blink alternate ? if blink the same time, it's probably a fatal error..
if blink alternately then the waste ink counter need to be reset and the waste ink pad need to be replaced.

Check the zener diodes over by the fuses, where the 2 chokes or load coils are. TThere are 3 or 4 Of the diodes, they are zener diodes. I had the same problem and found it to be one bad zener diode. Check my solution out on the 7202, same thing.

Blinks twice pause blinks 4 times


SYMPTOMS
Dead or Shutdown symptoms.
RESOLUTION
Dead symptom reported to be caused by the following:
1. Dead.
Found Q601 & Q602 shorted, R615 open, and IC600 on the A Board were the cause of the symptom.

2. Dead.
Found D614, Zener diode, on B+ line was shorted.

3. Set shutdown and the standby LED blinks 3 then 5 times.
Found 200v line was low. Disconnected CN706 on the C Board and found 200v now
present on CN706/pin 7.
Found: IC702 (C board) shorted the 200 volt line.
HQ Comments: C541 on the A Board could become defective if the 200v line is shorted since
the polarity on the capacitor will become reversed. R553 fuse resistor could also be opened
on the A Board.

4. Error code of 4 blinks .
Dead set press power button you hear the relay and you see red led flash 3 times and stops? Has no HV or other action. Tech removed the back as no 200 volt supply, did unplug CN706 and now has 200volts. Tech did remove the IC702 and same it comes up so needs this IC.

5. Dead. 5 blinks then 3 blinks. Found shorted Damper diode D504. Q502 has a built in damper, as well.

6. The TV does not turn On and the LED flashers 9 times.
Found one side of R610 open on the Base of Q690 on the A board.

7. Dead, 9 flashes, Q606
Would not start when cold, has stand by 5 but relay never energize.
No response from front panel or remote controls.
9 blinks is not in service manual.

Found Q606 (Zero Det.), on the A Board, had no soldered on the collector
of the transistor causing an intermittent connection.
Soldered the collector of Q606 and set returned to operation.
HQ Comments: Also refer to E30968554.

8. Dead. 5 blinks or 3 blinks
Found on the A Board D611 in the Power Supply open, and Hor. Output Q502 shorted.

9. Found Power Supply components D611 shorted causing Q600, Q601, and R615
to fail on the A Board.

10. No picture or sound. Standby flashes.
Found Q512 (Pin Out) shorted. on the A Board.





11. Dead. No sound or picture.
Found the FBT and Q502 were shorted, and R615 open on the A Board.

12. Dead
No power, Stand by light flashes 4 times.
Found T604 and IC601, replaced.
Found D611 on the A Board was the cause of the symptom.

13. Dead.
Found D534 shorted on the A Board.

14. Shutdown 4 Blinks.
Replacing R595, OCP Latch Q532 on the A Board, fixed the set.
PN 1-247-891-00, 330K 1/4 watt.

15. Unit shuts down after 15 mins.
Immediate shutdown - sometimes it give a 3 blink, sometimes nothing.
Found R595 (330K) was open located in the Q532 OCP Latch circuit.
R595 P/N 124789100 330k 1/4w

16. Won't power up. LED Blinks 4 times, B+ is very low
B+ is at 49V, +15/-15 only coming up to about 1 volt.
Wth Hor Out disconnected B+ only comes up to 50v.
Found D611 on the A Board was the cause of the symptom.

17. Intermittently does not turn on
Found a intermittent C633 on pin # 3 of IC600.
C663 P/N 113647911 Film cap .001uf 100v

I had the same problem twice now, I am on here looking for replacement parts this time. The last time I had this problem I took the VCR apart and found a small round piece just floating around inside the case. I took out the DVD player and placed the small round piece back on the small silver post in the middle of the DVD player angled side up. Hope this helps. This time it’s something different for me.

Sony 32XBR400 Wont Power On


I do not believe the set is too far gone. The standby light blinks codes up to 7. If the standby light blinks more than 7 times it usually means that there is a short on the clock or data line. There are several small zener diodes connected to the clock and data lines in a couple of different places on the main board. Many times I have seen one of the zener diodes become very leaky, usually along the back of the board, loading down the clock or data line which produces the symptoms you are seeing. If you have no experience locating shorted zener diodes and unsoldering and soldering small parts, allow a qualified tech to service the set for you.
