Image runner getting this error code (E261-0000) / how do i fix it


Code

E261-0000

Description

The intervals of zero-cross signals deviate from the tolerance range while the fixing heater is supplied with power

Causes

The wiring is faulty (short circuit, open circuit). The main power supply PCB is faulty. The DC controller PCB is faulty.

Remedy

1. Connectors Are the connector J205 on the main power supply PCB and the connector J308B on the DC controller PCB securely connected? (zero-cross signal: J205-7 <-> J308B-1) NO: Connect the connectors securely. 2. Main power supply PCB, Main controller PCB Try replacing the main power supply PCB. Is the problem corrected? YES: End. NO: Replace the DC controller PCB.?

E010


IR330, step 1- this Error is the main motor fails to rotate normally, does the main motor rotate until E010 turn on? if yes go step 5, if no step 2- harness wiring connectors around the main motor normal? if no correct the wiring, if yes step 3- does the voltage of J102-B12 on the controller pcb change to 0 VDC while the main motor is rotating?, if no replace main motor ( main motor driver pcb), if yes step 4-is there 24 VDC generated between J204-3 and J204-4 on the composite power supply PCB, if no replace the composite power supply PCB, if yes step 5 is the voltage of J102-B11 on the DC controller PCB about 5 VDC during WMUP? if no replace DC controller PCB. if yes step 6- Is there continuity of the harness between the image processor PCB and DC controller PCB normal J714-A14 to J113-A7 also 714-A16 to J113-A5 if yes to if no replace the harness if yes replace the DC controller PCB and the Image processor PCB.

Have power (backlite) but no screen (menu or any control from side buttons) will not turn off.


Try disconnecting the tv button pcb interface connection to the mai board once switched on and try using your remote control functions. If there is still no menu or functions, this cancels out the buttons pcb, and the fault is the main pcb.The voltages are ok which you mentioned..12v..5v and the 24v invertor feed voltage so it will be the main pcb..If you had sound and remote functions i would have said it may be the Tcon as well as the main pcb.
If the remote works ok with tv buttons pcb disconnected, then the problem is the buttons pcb.However, you have no picture..i presume nothing at all including 'no signal message or menu screen'. Therefore, with no bulging caps and correct votages to the main pcb, you will be right to change the main pcb.
PLEASE DO NOT CARRY OUT ANY ELECTRICAL REPAIRS IF YOU ARE NOT COMPETENT TO DO SO..ALL MAINS PARTS ARE DANGEROUS..GET A QUALIFIED TV ENGINEER TO CARRY OUT ANY REPAIRS IF THIS IS THE CASE.

Error261 in canon copier


E261
0000 The intervals of zero-cross signals deviate from the tolerance range while
the fixing heater is supplied with power.

Main cause The wiring is faulty (short circuit, open circuit). The main power supply
PCB is faulty. The DC controller PCB is faulty.

Making Corrections
1. Connectors
Are the connector J205 on the main power supply PCB and the connector
J308B on the DC controller PCB securely connected? (zero-cross signal:
J205-7 <-> J308B-1)
NO: Connect the connectors securely.

2. Main power supply PCB, Main controller PCB
Try replacing the main power supply PCB. Is the problem corrected?
YES: End.
NO: Replace the DC controller PCB.
