What are the toroidal coils?

Any store to purchased them. Do you have or can provide with some intructions on installing the toroidal coils and transitors.
I have heated up and done sodering on top of them but i is till have the same problem.
Monitor problem: After turning the monitor on for 3 to 5 seconds it turns off to a black screen.
I have done some sodering, specially, on dc jacks, but i have no other experience than that. Any pictures and instruction will be helpful.
Thanks,

On my monitor I had the 8 pin smt FET's short out. The CCFL transformers were not bad. You can use a ohm meter to determine if the transistors are shorted or open. If you use FET's like mine did, you can monitor the out put for voltage. Mine was 12 volts pulsed DC. Good luck.

Yukon 2.5 x50 nvrs tactical night vision rifle scope, works fine but making a strange processing noise when on?


Hello, don't worry about it. It is HV to the image intensifier tube. The battery voltage goes through control circuit then to ccfl inverter (here is were dc voltage is switch on and off and switch dc voltage is step up by toroid coil that has two input and only two out puts). By impulsing the coil with two different switch dc voltage on the input this make the current lag the two different phase voltage by 90 degrees. Here is where the strange noise is coming from. The toroid coil is encased in iron case and if half of this iron case is loose, it makes case vibrate so the noise.


Now, the voltage come out of the toroid coil is switching dc (one could call it AC because that what AC voltage is, it switch between positive to negative) this voltage is about 300 to 900 switching DC voltage. This voltage will be applied to a 1/2 wave voltage multiplier (this voltage multiplier with have anywhere four four stages to 10 stages depend on what the input voltage to multiplier is.

Low the voltage out of the ccfl inverter the more stages the multiplier will have.



Now, the voltage multiplier will double the voltage per stage to need image intensifier tube voltage of 12000 to 45000 volts---DC switching or AC what ever one wants to call it. This voltage will bit you but it doesn't have a lot current associated with it, the current would be in the 10 to 15 ua (micro-amps) 1/10X6 amps.

Hi, Toroidal transformer in Sakura AV-200T input is 220v I need 110v Thanks


Hello shole135, Hi, you need a 110v to 220v step-up transformer with 200 watts power specification. you can visit your local hardware store and find one. Don't replace the toroidal transformer.

This is caused by an option on the printer not be seated correctly or there's a prob. with 2000-sheet feeder option.

Usual Cause:
  1. Reset power or power the printer off and on.
  2. If this does not resolve the error:
  3. Power the printer off.
  4. Reseat all of the paper feed options on the printer:
    • Remove all optional drawer options, like a tray 2 or tray 3 drawer, and reposition them from the bottom up.
    • Reseat the printer on top of the duplex option, if one is installed.
    • Reseat other options such as the envelope feeder or additional output bins.



2000-sheet feeder option? See below:


Explanation of the Issue
A cable can come loose inside the 2000-sheet feeder option and cause one of the following three conditions to occur:

  • The printer displays a 982.xx error. NOTE: The .xx extension can be any number.
  • The printer displays a 990.xx error. NOTE: The .xx extension can be any number.
  • The printer does not recognize the 2000-sheet feeder option installed.
The issue is with a toroid on one of the cables (see the blue/black wire cable highlighted in the image below). When the 2000-sheet feeder option is moved, the toroid can pull the cable loose, causing an error. NOTE: This toroid was removed in later versions of the 2000-sheet feeder.

Monitor problem


You are experiencing an inverter board failure. You will need to replace or repair the inverter. The inverter drives the CCFL lamps that illuminate the screen if the lamps draw to much current or components on the board are overheating it will shut down the backlights. Some monitors have cold solder joints on the toroidal coils of the inverter that causes this problem, very typical with HP monitors, If you are handy with a solder iron you may try just re-soldering board and replacing push-pull transistors for a few more years of use. Provide make and model and I can be more specific about probable cause and solution.

No power


The inverter boards for the backlights fail on these HP F series monitors. Sometimes it is cold solder joints on toroidal coils. Sometimes the transistors that drive the output transformers (4). It is not difficult to repair if you have good soldering skills. I usually resolder the toroids and replace the transistors regardless of culprit. You may see the heating effects of bad components (discoloration) on the board.
