This indicates a failure during Power-on Self test that there is a fault with the DACS or secondary VDAC/IDAC readback.

If a simple on/off cycle of your power supply doesn't resolve the problem, your supply will require servicing.

Sir, i have hp laserjet colour printer CP5225, having error 55.0601. Kindly give me online solution


this all i manage to find for hope it helps

55.x Error
Error Message
55.X Error
Turn off then on
Description
The printer has experienced an internal error. The printer may experience one of the following errors:
55.0 DC controller communication error
55.0601 DC controller NVRAM data error
55.0602 DC controller NVRAM access error
55.1 DC controller memory error
Action
Turn off the power by using the power switch, wait at least 30 seconds, and then turn on the power and wait for the printer to initialize.
If a surge protector is used, remove it. Plug the printer directly into the wall socket. Use the power switch to turn on the printer.
If the message persists, contact HP support.

You need to first check the connection between the dc controller and the formatter and if the connection is fine you need to replace the dc controller.

I have the hpcolorlaserjet 9500n shows error code 50.6, how to solve


50.6 error is an open fuser heating circuit
between the fuser and low-voltage power supply.
Problem could be the fuser, the low voltage power supply
or the DC Controller.
The 1st thing to do is replace the fuser. If you have another one.
You should really call a printer tech to look at it.

Hi, I have hp pavilion dv2500 laptop. I have display problem.pls help how to rectify it. If i connect exteranl CRT monitor Display is coming . Pls tell me how to disassemble the laptop.


You might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.

In this service manual, you will find an illustration of how to disassemble the laptop & replace either the LCD cable or screen inverter board:

57.03 error shows in hp p 3005n laserprinter


Hello!
The 57.03 error relates to a problem with the fans, in particular, the right fan.  Try reseating the connector for the fan in the DC controller board.  (DO THIS WITH POWER DISCONNECTED!!!) If that does not fix the problem, it is most likely the DC controller board failed, which will have to be replaced.
Hope this helps you out,
Ken
