It's usually underneath the motherboard, but just look around if you don't see it on the top of the motherboard just extend the wire as far as it will go and look around there. It can't be further away then the length of the wire.

Wiring a Westinghouse 3way speed switch.


Three way Switch installation; One cable has two wires plus a bare copper grounding wire, The other cable has three wires plus a ground.
1. Connect the black wire from the two-wire cable to the dark common screw terminal. 2. Connect the red and black wires from the three-wire cable to the traveler screw terminals. 3. Join the white neutral wires together with a wire connector and pigtail the grounding wires to the grounded metal box. 4. When the switch lies at the end of the circuit one cable enters the box. 5. The cable has a black wire, red wire, and white wire, plus a bare copper grounding wire. 6. Connect the black wire to the dark common screw terminal. 7. Connect the white and red wires to the two traveler screw terminals and the bare copper grounding wire to the grounded metal box.
I hope this help.

How can I eliminate the click from the Mad Catz Wooden Fender Stratocaster controller?


This is a pretty easy fix, if you have basic soldering skills. Total time is about 30 minutes.

Tools & Materials Required
  • Pencil soldering iron
  • Small phillips screwdriver (size PH1 works well)
  • 2x CH310-ND switches from Digi-Key ($1.49 ea.)
  • (Optional) Fine wire solder
  • (Optional) 2-3" zip-tie


Step 1: Remove the six screws holding on the rectangular back cover, and cut the small zip-tie holding the cables together.

Step 2: Remove the screws from the front white cover and gently pull the cover away from the guitar body. You will need to work the ribbon cables through the small opening to the back cavity. You should end up with enough cable free to flip the front cover over.

Step 3: Remove the four screws holding down the strum switch circuit board and flip the board over. You should see two blue-top switches that look very similar to the CH310-ND switches. Note the Up/Down labels on the back of the circuit board. You can put either switch into either socket, but you must install the circuit board in the correct orientation when you are done!

Step 4: Apply your soldering iron to the two connection pins on the back of the circuit board until the solder liquefies. Quickly move to the other pin and repeat. Once both have liquefied once, you can move back and forth for just a second or two on each pin and slowly work the switch out of the circuit board. There will be plenty of solder left in the pin holes to connect the new switch. Optionally, you can use a solder remover to completely remove the solder from the pin area, then apply new solder with the new switch.

After the old switch is removed, align the new switch and insert the pins into the connection holes (they will not go all the way through). Heat up the solder that was left behind, again alternating between pins, and gently push the switch all the way into its mounted position. Make sure it is resting flat on the circuit board (there will be a small gap between the bottom of the switch and the circuit board, but the switch should be completely level; compare with other switch).

Step 5: Repeat Step 4 for other switch.

Step 6: Reinstall circuit board in correct orientation. Push ribbon cables back through hole and reinstall front cover. Optionally re-zip-tie ribbon cables, flatten them into the rear compartment, and reinstall rear cover.

Step 7: Rock on in silence!

Problem with Toshiba Equium Laptop which is switching itself off. even when connected to mains supply Is this a problem with the switch or power supply? Hope you can help thanks


If the laptop shuts down and won't boot up straight away, then the problem could be an overheating CPU problem. It could be a faulty fan and/or the fan and heatsink assembly is clogged with dust.
Check the fan and if it has stopped spinning then replace it and if the fan and heatsink is clogged with dust, loosen the dust and remove it.

Red light blinking no picture no sound


tart checking the cable connection to receiver, try moving or replacing cables.

If you have a surround with external speakers check surround connection cable and speakers wiring.

If the cables are OK, then the unit may be faulty.

In that case the fault can be either the audio board (often audio circuit is integrated on the main board) , or the sinput output signal board.
Also a contact on connection to internal speakers can give you same problem.

RCA 27R410T my tv turns itself off and on


My one year old 24" RCA was having the same problem and also changing channels on its own. I decided to do some experimenting. (Warning: High voltages exist inside a TV even when it is unplugged. Messing around inside a TV may be very dangerous and stupid.)

I found that there was a 5 wire ribbon cable that connected the circuit board with the front control buttons to the main circuit board. I discovered that if I turned the TV on, then disconnected that ribbon cable from the main circuit board, the TV was stable, it would not do anything on its own. Obviously, I could not control it either with the ribbon cable disconnected.

Since there did not appear to be any ic chips on the button circuit board, but mainly some resistors, I theorized that the buttons simply caused a certain voltage signal to be returned to the main board. I further theorized that perhaps the voltage being sent to the board was varying causing the return voltage to also varying making the main board thing a control signal had been sent.

The five wires are labled on the small control circuit board. One was labeled "key". (or maybe "keys") I separated and cut that wire. The TV was then stable. It could be controlled by the remote control, but the buttons on the front were now not functional.

I connected some longer wires to the "key" wires and ran them outside to a switch. The TV now works fine with the remote control and is stable and will not do anything on its own. If for some reason I do need to use the manual buttons on the front, I can simply flip the switch on and the buttons will work. However if I leave the switch on the TV will again be unstable, turning itself on and off and changing channels.

That is how I "fixed" my RCA.
