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.

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:

HPLJ 4350 58.8 error?What is this error referring to?


Here is the information courtesy of the HP website.

Happy Thanksgiving,

58.X PRINTER ERROR alternates with 58.X PRINTER ERROR To continue turn off then on Description A printer error has occurred where a memory tag central processing unit (CPU) error was detected, or there is a problem with the air sensor or power supply. X Description 2- air-temperature sensor 3- DC controller 4- power supply Action
  1. Turn the printer off and then on.
  2. Remove the printer from any universal power supply (UPS), additional power supplies, or power strips. Plug the printer into a wall outlet and see if this resolves the problem.
  3. If the printer is already plugged into a wall outlet, try another power source in the building that is independent of the one currently being used.
  4. The line voltage and current source at the printer location might need to be inspected to ensure that it meets the electrical specifications for the printer. (See the printer User's Guide for information about electrical specifications.)
  5. If the message persists, contact HP Customer Support.

Reseat connections to the specified fan and DC controller.
If the error persists, replace the specified fan.

Use the Figure and table below to properly identify the 57.X error and the corresponding fan that is causing the error message.

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
