Pro-96 scanner My unit has been in repair 3 times for the same problem. the last service call they actually replaced the system board. Problem: scanner will not work until it is hot. After leaving unit on for about an hour, I am finally able to use. Any thoughts?

from service handbook:
[F110] Communication error between system CPU and scanner CPU
[F111] Scanner response abnormality
(1) Check if the harness connecting the SYS board and SLG board is disconnected or open circuited.
(2) Check the version of the system ROM on the SYS board.
(3) Check the version of the scanner ROM version on the SLG board.
(4) Replace the SYS board.
(5) Replace the SLG board.

from me:
Try power off, then press and hold 1 + 3 + * and power on
after
power off again, then press and hold 1 + 3 + # and power on

You cannot repair this error easily. Most times its the main board that has the problem but its more than likely to be the scanner pcb than the main board. I am actually in the middle of the very same error and have tried the main board and it is the scanner pcb that is causing this particular problem. As you do not state what model you have , I cannot give you a part number.

You may need to replace the laser, it may have failed, this is from the service manual

E100

0001 The BD signal is not detected 10 times or more within 10 msec in 5 msec

after the generation of the laser drive signal.

0002 While the laser is ON, the BD signal cycle is outside a specific range 20

times or more continuously.

0003 While the laser is ON, the horizontal sync signal cycle is outside a specific

range 20 times or more.

Main cause The wiring is faulty (short circuit, open circuit). The BD PCB is faulty. The

laser scanner unit is faulty. The DC controller PCB is faulty.

Action

1. BD PCB

Try replacing the BD PCB. Is the problem corrected?

YES: End.

2. Laser scanner unit, DC controller PCB

Try replacing the laser scanner unit. Is the problem corrected?

YES: End.
NO: Replace the DC controller PCB.

C3C50 at power up.

PROBABLE CAUSES:

1. Loose connectors or failed PWB-C board.
Reseat all connectors and then replace PWB-C board (p\n 65FA-9360) if necessary.

2. Poor connection for the interface cable between the MFP and scanner.

Reseat the MFP-to-scanner interface cable its a large molex cable with thumb screws to remove on the outside of case.(p/n 4581-6876-01).

3. Failed PWB-F board.

Replace PWB-F board (p/n 4025-0103-27). Flash MFP with most current firmware. The latest version firmware or system software is available via the Konica Minolta Download if you need help with this write me back.

4. Incorrect scanner serial number.

Access service mode and select System Input. Verify the correct scanner serial number has been input under Serial # Input.this is in Service mode. if you need help with this write me back

It is a common problem, usually associated with moisture physically on the board or improperly installed communication cable (18-22 AWG shielded stranded Cu cable required). The PCBs are tightly packed and are frankly not worth the time it takes to diagnose and repair them. Replace the PCB and make certain that the original install was done correctly with the correct materials.

E100 Scanner unit failure
Cause: (1) Poor contact in the laser/scanner unit connectors(2) Defective laser/scanner unit(3) Poor contact in the ECU board connectors(4) Defective ECU boardSolutions: (1) Reconnect the BD board connerctor (J871), laser driver board(J801), and scanner motor connector (J851).(2) Replace the laser/scanner unit(3) Reconnect the ECU board connectors J913 and J914 correctly.(4) Replace the ECU board.

1. YOUR flyback is going bad 2. Peform a removal and replacement 3. check your error codes first to ensue nothing else exists 4. Proceed to change out the required parts 5. Observe all electrical risks 6. Order replacements from jimmyparts.com 7. Ensure to always remove power 8. Ensure to always use electrostatic wrist strap
Generally what occurs is the units soldered connections on the main projection board warm up as the system warms up. Thus, the loose capacitors, resisters, and diodes are causing the CHANGE when the system warms up. When metal contracts, it expands thus losing the connection needed for a solid connection. This process is normal after the units have reached their service life. Keep in mind that you can repair this but at the expense of time if you have never performed this type of work.

On the X305 the video card is actually 3 boards sandwiched together. there are 2 actual video cards plus the SLI control board. I have a feeling that Toshiba was just replacing the failed board and not actually addressing the cause. In your case I would say that either the SLI control board is faulty or there is an active component on the motherboard that is causing an over voltage issue in one of the video cards. In any case you are looking at some pretty serious money to get this issue resolved. I personally would try a reflow on all 3 graphics boards and if that didn't work I would look to replacing the motherboard and the video cards.

Hi,

There may be four (4) ways the repair could be done:
1. board - an entirely new power board maybe available from the monitor manufacturer or you can Google for OEM provider;
2. board - a refurbished/reworked board may be available, again you have to Google. Both 1 & 2 would require that you search for the actual PCB assembly number;
3. use the power supply board from an identical unit that has defective LCD panel, inverter or other problems/defect other than the PSU; and
4. component level repair - determine which components in the power supply are defective and needs replacement.

All of the above would require time. Time to look for the replacement board, time to determine which component to replace, time to do the actual repair.

Cost - depends on the tech. Of course board assembly would cost more to purchase but should be relatively easy to perform and therefore should not be expensive in terms of service. On the other hand, component level repair often would be cheaper in terms of parts purchases but would cost more in terms of service fees.

Taking into considerations the above factors, it may be more to your advantage to do the repairs yourself (no service fee). Still should you be uncomfortable on a DIY, then the cost of repairs might justify the purchase of a new LCD monitor instead.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
