How do I get the sim card out of my I phone 5?


Turn the phone COMPLETELY OFF.

- Put on your anti-static wrist band.

Remove the protective case ...
if you have one on your phone.

On the right side of your phone...
observe a narrow 5/8 inch slot with a small hole in it...

Using the appropriate release pin... (or small paper lip)
gently push into the hole and this will release your
SIM CARD...

Keep in mind THE tiniest STATIC spark can
(you might not even feel) utterly destroy the
most ROBUST of semi-conductors...

EVEN those big UGLY diodes in your cars alternator...
so always wear ESD (electro static discharge)
protection when handling any semi-conductors
YOU CARE ABOUT.

What does esd strap stands for led tvs


Ground for Workbench
Be sure to place a conductive sheet or copper plate with proper grounding (1 Mohm) on the workbench or other surface, where the semi-conductors are to be placed. Because the static electricity charge on clothing will not escape through the body grounding band, be careful to avoid contacting semi-conductors with your clothing.

Numark ttx1 blowing fuses


Fuses blow when there's an overload. Most are caused by a semi-conductor that has shorted. If it was the bridge you can test with an ohm meter. Connection across it's leads will be just like touching the test probes together. That goes for any of the semi-conductor devices.

Panasonic PV-4664 VR wont't power on. Replaced 1.6A input fuse and fuse blows immendiately when power supply is both installed and removed from the unit. Appears the power supply has a problem.


Fuses blow like that when a semi-conductor has shorted and acting like a piece of wire. Transistors diodes etc will show up quick with a Ohm meter, has it will be just like you have touched the probes together!

MY FUSE KEEPS BLOWING OUT


If the fuse keeps blowing it's because some part is acting like it is a piece of wire. It will probably be a semi-conductor in the power supply of the turntable, or the transformer. They often look burnt or damaged the semi-conductors in this state.

A small 2.5 amp fuse keeps blowing. It is located at the back of the unit just after the ac inlet


When a fuse blows suspect an overload in the power supply or power amp section.
For culprits in the power supply check the transformer, large capacitors, rectifier, voltage control semi-conductors, diodes.
In the amp section any semi-conductor on the heat-sink.

Semi-conductors - transistors and IC's are the biggest cause of fuse blowing. They become short-circuit acting like a piece of wire!
Because of this transistors and diodes are easy to spot with an Ohm Meter, as it will be like you have just touched the probes together.
Very often they have holes, or damage, or have burnt up with this kind of fault.
If it is a fault on the main amp section, check your speaker wiring as the + & - wires could have touched to cause it.

R52wh74 Convergence


If the convergence option is not on the menu anylonger. thats another issue all together. That is usually a fusible link and capacitor on the deflection board that will cause that to happen. The convergence ICs will also need replacing as the link and capacitor will most certainly take out the convergence ICs as well. You will need a service manual on this issue. Let me know and I will post a link where you can get one along with some free support to help you with it.

Blue convergence will not move left or right


look at the convergance board it will be the one on the left there re two stk semi-conductors tward the back of the board. most likly one of them are bad but sometimes the soldering can be faulty. look for signs of cold solder if so just resolder and should be good if not also look for burnt resistors. it will be obvious finding the stk 's can be done by using google and just type in the stk # finding the resistors you might try calling panasonic to find the part #by telling them the location of the burnt resistor. good luck. mind you that the soldering of the stk (semi-conductors) you will want to use a heat sink on each terminal you solder otherwise you take a chance of burning the conductor befor you ever get to use it, if you have no exp. soldering i wouldnt sugest trying it !!!!
