When i go to turn on my LG 50PG20D-AA plasma tv, the green power light turns on for a couple seconds, the LCD turns on, then flicks off again, it keeps repeating the process until you disconnect the power...


everyone is wrong here.

Disconnect the power from the mainboard the board down on the right hand side.

now short out the auto_gen with a peice of wire while tv unplugged.

after this process plug it in.
You should see a test pattern this will rule out Y-sus and Z-sus problems.

Problem will be main board.

I refill the cartridge of my canon mp496 printer.I print images and everithing is ok but the ink lamps are orange .I don't know what to do ! Please ,help me !!


One of these reset methods should fix the problem

This is the procedure I used for an MP470. It is basically a modified version of that previously posted for the MP460.

1. Disconnect the power cable.
2. Hold down "On/Off" button.
3. Reconnect the power cable.
4. With the power button still down, press the "Stop/Reset" button twice.
5. Release the "On/Off" button.
6. The printer is now in "factory mode".
- wait until "idle" is displayed.
7. Press the right arrow button (next to the "OK" button) repeatedly until "Shipping Mode 3" is displayed.
8. Press the "OK" Button
9. Wait until "Without Cleaning" is displayed and then presss the "Stop/Reset" button once. (I pressed the ok button after Stop/Reset button on my MP470).
10. A test page should print.
11. Open the cover.
- the cartridges should position themselves at the far left - the cartridge removal location.
12. Disconnect the power cable.
13. Remove both cartridges.
14. Close the cover.
15. Reconnect the power cable.
16. Press the "On/Off" button once.
17. Wait until a "Replace Cartridges" message is displayed.
- insert cartridges.
18. Wait until the printer is operating in its normal mode. The display shows the normal start menu (ie: Copy).
The ink levels have been reset.
- check by going to printer>properties>maintenance>view printer status



this is what i had to do to get it to work with canon mp460
1. Disconnect the power cable
2. Hold down power button
3. Reconnect the power cable
4. With the power button still down, press twice the "Cancel/Stop" red button
5. Release the power button
6. The printer is now in factory mode...(wait about 30 seconds until it says "idle")
7. Press the down arrow (next to the "OK" button) until it says "Shipping Mode 1"
8. Press the "OK" Button

12. Disconnect the power again
13. Take both cartridges out like normal
14. Close cover
15. Reconnect power cable
16. Press power button
17. Replace cartridges







MP-160 is different from MX300 so I tried my best with it...
The main solution is to reset the entire printer:
1. Disconnect the power cable
2. Connect it while holding down the power button
3. With the power button still down, press twice the "Cancel/Stop" red button
4. Release the power button
5. The printes turns into a kind of factory mode...(wait for about 10 seconds, utils it says "Idle")
6. Press the ">" (next to the "OK" button) once."Shipping Mode 3"
7. Press the "OK" button.
8. Press "OK" again for "Without cleaning"
9. A test page will print..
10. Open the cover, like you are about to change the cartridges.
11. Disconnect the power cable again.
