imageRUNNER 3225 / 3230 / 3235 / 3245 Blank LCD Display or No Power to the Main Unit

When the Main Unit is turned on, either a blank LCD display occurs or no power occurs. In some cases, the control panel buttons work, but the display is blank.


If the Main Controller "registered value" ID does not match the REAL TIME CLOCK (RTC) ID, the Main Controller Malfunctions; preventing the LCD display from powering up or no power to unit. By shorting JP1 on the Main Controller it will clear the RTC "registered value", to correct the ID between the Main Controller and RTC Circuit.

Procedure:
1. Turn OFF the Main Unit.
2. Either unplug the power cord from the wall.
3. Remove the rear cover of the Main Unit.
4. Below the left leg of the Battery, jump JP1 for 3-5 seconds.
5. Plug in the power cord and turn on the Main Unit.
6. Verify that the Main Unit powers ON and that the LCD display works.
7. Re-install the rear cover.

Is the green light showing on the LCD panel?

Also, Teckat, how do you short this pin? I am not familiar with this method. I usually just replace the LCD screen.

Thanks,

That Is exactly what I'm looking for teckat, thank you. Is this the same for all models? Only I have had this screen fault oh iRC2380i. Is the RTC ID kept on pin JP1 on all machines?

Thanks in advance

LCD Display is completely Blank
LCD Inverter PCB

new style LCD Inverter PCB (Part Number FM4-6690-010) now has a jumper, JP4, on it. Also, there may be one of two different style LCD's in the machine, each with a different style connector to the Inverter PCB. There are two positions for jumper JP4 depending on which LCD you have.

If the LCD Display's connector plugs into J2 on the LCD Inverter PCB, the jumper for JP4 should be positioned all the way to the left for the LCD Display to work properly. Please refer to the picture below:

If the LCD Display's connector plugs into J3 on the LCD Inverter PCB, the jumper for JP4 should be positioned all the way to the right for the LCD Display to work properly. Please refer to the picture below.
