To remove the low voltage power supply, Take off the side covers. the power supply is on the rear right hand side of the printer. Just remove the screw's and the cable's connected to it and your done. Don't confuse it with the Hi voltage power supply which is on the Left side of the printer as your facing it head on from the control panel.

Hi I have a car amp in my room which is hooked up


Car amplifiers cannot be powered by laptop power supply. These amplifiers have different power ratings. You need to check the Car amplifiers power requirements / rating (Voltage & Current requirements) and then get a power supply with the exact same Power ratings. If the power supplied to the amplifier is less than the rated power it needs, it will not be able to drive the amplifier IC's and transistors in the amplifier and will not produce good sound.
Please check the power requirements for the amplifier and buy a suitable external power supply for it.

CCTV power supply keeps decreasing the voltage


Your power supply appears to have a capacitor that is breaking down located within the diode bridge. You will need to replace the power supply or get it repaired.

I plug in my tv with a 125v cable my tv and nothing happens.


Good day!Follow this D.I.Y procedures to find the exact problem of your TV.
  1. Remove the back cover of your TV.
  2. After that,find the power supply board.
  3. If you already found the power supply,plug-in your TV and power it ON.Check the input voltage of it,using multimeter (AC range).If the power supply have no input voltage the problem could be the power cord.Replace it.
  4. If the power supply have the input voltage,try to test the output voltage if have 5vdc for the system and logic supply,12vdc for the sounds and 24vdc for the back-light inverter.Use your multimeter tester (DC range) to test that.
  5. If the power supply have a voltage outputs such as 5vdc,12vdc and 24vdc and the problem is still there.The problem could be the main board.Replace it with the same type and model # because the main board is no very difficult to fix and its very sensitive.
  6. If the power supply have no output voltage or the voltage is too low,just ignore the step # 5 because the problem is not on the main board,its on the power supply board.
Check the following to fix the power supply board:
  • Fuse: Check the fuse if it is busted or blown.
  • Power transistor (regulator): Check the regulator if it is shorted or leak.
  • Resistor: Check the resistors specially the one that have a low resistance that near the power regulator.
  • Capacitor: Also check the capacitors if it is leak or bulging top.
NOTE: If you found any defective parts or components that mention above replace it with the same value,type and ratings.

I hope this solution will be helpful.Thank you and good luck.

Hi, i have cp2025 printer and it giving an error 58.04 could you please help thanks


Hi,

Solution or Workaround:
NOTE: Replace the low voltage power supply before replacing the fuser or fuser power supply.

A firmware upgrade is available on www.hp.com that will solve this issue.

If the error will not clear after the firmware upgrade, replace the low voltage power supply.

If the error continues, replace the fuser power supply.

If the error still continues, replace the fuser.

Cause:

Low voltage power supply malfunction.

I hope this information helps

Actually if your TV have problem like that it is not on the inverter.That problem could be on the power supply or the system board.

  3. If you already found the power supply,plug-in your TV and power it ON.Check the input voltage of it,using multimeter (AC range).If the power supply have no input voltage the problem could be the power cord.Replace it.

Low voltage power supply


What is the error message you are getting with the new fuser. Is this the same error you were getting before changing the fuser? If you changed the fuser because the old one was just at EOL ( end of life) but did not give you an error, have you tried to reinstall the old fuser.

It is possible that the new fuser was damaged in shipping, or not properly seated.

If both the new and old fuser give the same error message, then yes, I would agree that the LVPS would be the next part to replace, however, if they have different errors, then you probably have 2 bad fusers ( or one that is EOL, and one that was received damaged).

Before changing the LVPS, make sure you follow the steps below prior to the LVPS steps.
as far as where to purchase it if you do in fact need one, you can always do a google and ebay search for "Dell 5100cn LVPS".

I can provide you with replacement instructions if it comes to that.

See below for the actual troubleshooting needed for the fuser.
The following steps are the troubleshooting steps that should be followed for error code 010 397.
First, the definition of the failure is <IOT Fuser Failure>, and means a Fuser Error is detected.

1) With power off, reseat the fuser by physically removing it from the printer, then reinstalling it and locking it in place. Turn the power back on. ( if the error is still present, proceed to step 2 ).

2) If reseating the fuser did not resolve the problem, Replace the fuser with a known good fuser.
( if problem is not resolved, proceed to step 3)

3) Replace the LVPS ( low voltage power supply ). ( if problem not resolved, proceed to step 4 ).

4) Replace the PWBA MCU ( printed wiring board assembly - machine control unit ).

END of troubleshooting.........
