Two inductors 100mh and 75mh in parallel in series with a 5v power supply and a57.14mh. What is the frequency?


Isn't the frequency imposed by the voltage source?
The equivalent inductance is about 100 mH
100*75/(100 +75) +57.14 or about 100 mH.
You have a voltage source connected to an inductor with inductance equal to 100 mH. Then what? You need at least the peak current value, don't you?

Hi all i own a behringer XENYX 802 audio mixer. this device is powered by a power supply that as input to the mixer gives 18,5 x2 Ac, 150ma. i would like to know in which point of the circuit i can...


You would need TWO DC supplies as they use AC so they can create both a plus and minus 15 volt power source to run the internal op amps.

Here is a schematic for the 1202 which has same power supply configuration as the 802.

Scroll down to the little link "Get Manual" and download the service manual and schematic. You will find the power input in the upper left corner of page 5.

Here's a hints on how to repair or fix Nokia 5800 XpressMusic Digi Mic Knopfler problem issues.
A guide picture below which I included an schematic diagram shows each every components and line paths for quick test and check up procedures.
Digi Mic Knopfler Pin configuration:
1. L/R - microphone's left and right audio signals groundings
2. CLK - Audio Clock data
3. Data - Digital Microphone data
4. VDD - Power supply voltage

http://2.bp.blogspot.com/_8JZhVVmpICU/TBnMEY2FYyI/AAAAAAAAAiI/KWb0ERKLIPE/s400/digi+mic+knopfler+schematic.jpg


Locate and trace each and every components, line paths and corresponding connection as shown on a picture. The red highlighted components and line paths is for the power supply voltage which came from Power management IC (AVILMAS) Vsim2- approximately 2-3 volts.
Test and check this components and track the supply voltage from C220 to C2170 then through the digi mic knopfler pin 4.

http://4.bp.blogspot.com/_8JZhVVmpICU/TBnNuXjiK5I/AAAAAAAAAiM/zRyjq5oSGEA/s400/nokia+5800+xpressmusic+digi+mic+knopfler.jpg

The pink highlighted components and line paths is for Audio Clock data signal, which is came from the Audio Codec IC (Avilmas) then flow across R2201 and R2170 (valued 100ohms each) then to the Digi mic knopfler pin number 2. Check also the C2173 valued 22p Clock filter capacitor for possible damaged.
I included step by step procedures on the images like as follows:
* Check each components and line paths.
* Replace if found open or shorted
* Jumper the line paths if found open or cut
* Check or replace the digi mic knopfler for a quickest step might as possible.

The microphone's digital data signals has also a line paths connected to the front side of the Printed circuit board, check and trace also this line paths which is connected to digi mic knopfler's pin 4

My t1500 XR keeps clicking on and off when i connect it to the power suply. why is that and how do i solve it?


that is because the power outlet it is plugged into probably doesn't have a steady voltage. which means that if more things are plugged into the outlet then the power could be going from 120 volts to 99 volts to 130 volts and it could be going up and down like that. your ups thinks that when the power goes really low or really high their is a power outage or surge. so it clicks to battery. then when the voltage steadies out it clicks to house current. you will need to configure the ups to have to tolerate that kind of voltage. by plugging the data cord in to your computer it is either a Ethernet to usb or usb to usb, you know a cord that plugs into the ups to the computer to let you configure it.

No sound from tv with philips HTS8100 THEATER


Hello,

First, check you menu settings for (High Definition Media Interface) HDMI on your TV and on your home theater system, if they are correct then, I have bad news the HDMI port on your TV or on your home theater system has been blown. This is a common and on-going problem with HDMI. The control circuitry is suceptable to stray voltages, which cause the HDMI IC and circuit to malfunction.

I would suggest if it is the HDMI port, having a qualified TV technician troubleshoot the problem and give you an estimate on the cost of repair.

However if you want to try to do this yourself, here is what you will need:

1) schematic of the TV
2) multimeter
3) Oscilloscope (optional)
4) HDMI signal generator (This can be improvised if you have a background in electroniocs)

First unplug the TV and remove the back cover. Then using the schematic find the voltage rail that suppllies voltage to the HDMI port. Plug the tv back in and turn it on. Using the multimeter set to DC volts measure the voltage on the HDMI port control IC and compare it to the schematic values, if they are different within 10% then you have a problem with the IC and it needs to be changed out. If there is no DC voltage difference the look deeper into the circuitry, and follow the path to the main processor, checking the voltages and comparing them to the schematic values. If this proves to be unsuccessful, use the oscilloscope to look at the wave forms (These will be digital pulses) and compare them to the schematic values (they should be as close as possible to the schematic values).
Once you determine that the problem is in the HDMI IC you will need to remove the IC by desoldering it. After the IC is removed clean the area and then replace it with a new HDMI IC.

If you need asistance with the process let me know and I'll try to walk you through it. The best bet however is to call a TV technician.

I hope this helps,

Thank you,

Hello zang,

 

This denotes a problem with the switching power supply or the high voltage power supply. what is happening is the safety relay is being actuated by the shutdown circuit. Any number of things can cause this proble but more then likely the problem is in the high voltage power supply section and or its associative circuitry. The switching power supply and the high voltages power supply have very dangerous voltages and I would not suggest that you work on the TV set unless you do have a background in electronics. If you do not I would suggest that you take the TV set to an electronics shop for repairs. If you do have a background in electronics, you will need the following items:

 

1) A schematic diagram (to know where voltage and signal test points are located and to have a reference of the levels.

 

2) A multimeter (to measure the DC voltage levels on the TV Set)

 

3) An oscilloscope (to measuer the AC voltage and signal levels in the TV set and compair them to the values in the schematic)

 

4) A signal generator (to generate a reference signal for troubleshooting)

 

I hope this helps,

Hello Big Bristow, It sounds like you may have a shutdown problem. This will require troubleshooting of the television. I must ask if you have experience in electronics, I ask because this is what you will need to troubleshoot this problem: a schematic of the television (to know the correct voltages, signals and signal levels) a multimeter to measure continuity of fuses, and the voltage level to match with the schematic values. an oscilloscope to measure the signals and signal levels and compare them to the schematic values a high voltage probe to measure the high voltage points on the set. These are the basic pieces of equipment needed, in the more advanced are you will need a NTSC signal generator (the Sencore VA62A Universal Video Analyzer does a good job). If you dod not have a background in electronics I would not advise you doing any work on this set and you should take it to a TV repair shop.
