Is the green light indicator on??

hi dear every one please tell me i have Canon Ir3200 in the penal of machine there is nothing appear. any one please help

first do a simple test below >>






Adjusting the Brightness of the Display Panel adjust the brightness of the display panel?


If the touch panel display is difficult to view, use the display contrast dial on the control panel to adjust it's brightness




Note: To make the touch panel display brighter, turn the dial counterclockwise. To make it darker, turn the dial clockwise.

**Check Display contrast dial on the control panel to adjust its brightness/to make the touch panel display brighter, turn the dial counterclockwise. To make it darker, turn the dial clockwise.

**Ensure that the voltage between the neutral and ground poles is 1/2 a volt or less. If the voltage is higher than 1/2 a volt, an electrician needs to look at and correct the outlet.

**There are many reasons the LCD screen on the C3220 is blank, but this scenario gives a hint. The Main Controller PCB has an LED101, which is ON during normal operation. When you experience a blank LCD screen, inspect the Main Controller PCB LED101, if the LED is OFF; replace the SRAM PCB (FG3-3669-000) which is mounted on the Sub Main Controller PCB.

**There could be a problem with the memory, a blown fuse on the Fuse PCB, a defective control panel, boot rom, memory, etc

**Re-seat the memory DIMMs, the boot ROM, the control panel connectors.
and the Option Boards (Network/Resolution/Open interface). If the problem still exists replace the Power Distribution PCB. (FG6-9676-000

**Check/or Replace Fuse PCB. The fuse for the voltage for the control panel could act like a resistor. And drop the voltage from 3.3 vdc to 1.2 vdc.

**You turn the machine on and there is no display but the green light comes ON. After 30 seconds or so, the green power light goes OFF.

**The unique difference with this situation and other blank display issues is that the green power light turns OFF after 30 seconds (Do not overlook this). First turn the machine OFF, unplug the hard drive from the system and turn the machine back ON. See if the splash screen displays on the control panel, as this will confirm a bad hard drive. It is possible that a bad hard drive could short out the system and cause this symptom. Therefore you must replace the hard drive.

**NOTE: This theory of a bad hard drive shorting out a system occurs also on a regular computer where no power is present. You unplug the hard drive and the machine comes back to life.

**When the main controller fan was unplugged the display would come up and the machine would then give an E code.

**Check the connection between the Sub-Main Controller (J1303) and the Main Controller (J1209) to see if they are seated correctly. When installing the Sub-Main Controller press the connectors together, and then install the standoff screws

yes green light on

yes green light on

yes green light on

have u check for proper wall voltage /
also check your neutral to ground voltage/ should be 0v to 0.5

well run some/check tests shown above- if u are a tech/ if not call for service

yes green light on

Are you a tech?

...looks like something had shorted somewhere. If all of the above recommendation fails, try replacing the hard drive again but this time without the fax board...good luck.

Did I miss something... Where is the fax board.

A bad DC power supply PCB can cause this as well.

1) Check whether DC line is supplied to the fuse PCB J57 from the DC power supply PCB J157. If no, check the DC power supply PCB.
2) Check whether AC line is supplied to the DC power supply PCB. If there is no problem with the AC supply, replace the DC power supply PCB.

I assume there is. Had similar problem with 2 units where the fax board shorted some PCB's. Symptoms: Dead panel with green indicator "ON"....just suggesting

[blazebusiness]

Check the dc pwr supply voltages as per Screwtape . That's the best advice. Not a bad idea to check all the other possibilities as per Teckat's list also-----but always start this type of diagnosis by checking pwr supply outputs first before moving on to other possibilities.

I understand now.

I've never seen this happen before.

Thanks for the heads up.

Thats a new one on me also-----------never seen it. Either way this poster never stated that he has the fax option installed. These units rarely have the fax option in my experience. Interesting info though.....

Fax function come as default, not as optional in my region as some rural area may not have broadband coverage and the subscription are cheaper too.
