They are solderd in. the heat sink compound will harden making it a little difficult to pry them from the heat sinks but they will come loose. be sure to apply new heat sink compound available at radio shack. You can get new ICs STK392-560 here.

Instructions

1

Purchase a new fan for the Sony Vaio model you have by checking the owner's manual of your computer or consult the Sony website for the correct part number.
2

Remove the power cord from your computer and then remove the battery. Unlock the battery and slide it from the bottom of the laptop. Allow it to sit for 5-10 minutes after removing the battery.

4

Slide the panel covering the power buttons to the left and detach the ribbon cable connecting it to the motherboard and then remove the panel gently.
5

Remove the keyboard by unscrewing the small screw directly above the keyboard. Once the screw is removed, gently lift the keyboard and detach the small cord connecting it to the motherboard. Set the keyboard aside.
6

Remove the plate under the keyboard by unscrewing the three screws and lift the plate out.
7

Disconnect the cooler fan from the motherboard by pressing the connectors in and removing them from the sockets. Once the connections have been removed, lift the cooling fan up out of the computer.
8

Replace the old fan with the new one you purchased and attach the two connectors. Reinstall the metal plate back on top of the fan and attach the screws.

How di i change the batteries in my Casio Pathfinder 2782


  • Choose a quiet, well-lit room where you can replace the battery in your Casio Pathfinder watch. Prepare a table, desk or other clean, flat surface where you can perform your watch repair. Put down a soft cloth or piece of craft felt to protect the face of your Casio Pathfinder watch from being scratched during the battery installation process.

  • 2

    Set your Casio Pathfinder watch face-down on the soft cloth or craft felt. Use an optical-sized Philips screwdriver to remove the four screws that secure the watch back to the body of the watch. Set the screws aside, but don't lift the watch back.

  • 3

    Slide the watch back off of the body of the watch very slowly. There are three important springs held underneath the watch back; it is essential to remove the watch back slowly to avoid losing them.

  • 4

    Lift the three springs out of your Casio Pathfinder watch using a small pair of metal tweezers. Take note of the length and placement of the springs as you remove them. Set the springs aside with the other disassembled watch components.

  • 5

    Take the black rubber protective disk out of your Casio Pathfinder to reveal an identically-shaped white plastic disk. Remove the white plastic disk and set it and the black rubber disk aside. Use your metal tweezers, if necessary, to lift out the rubber and plastic disks.

  • 6

    Release the battery strap that holds the battery in place in your Casio Pathfinder watch by pushing the battery strap latch to the left. Remove the old battery from your Casio Pathfinder using a pair of small plastic tweezers.

  • 7

    Pick up your replacement watch battery with the small plastic tweezers and insert it into the battery compartment of your Casio Pathfinder watch. Replace the battery strap and push it gently with the tip of your plastic tweezers to snap the latch in place.

  • 8

    Touch the "-" and "AC" terminals on your Casio Pathfinder watch with the tips of your metal tweezers for at least two seconds. This helps ensure that your watch will work properly once reassembled.

  • 9

    Put your Casio Pathfinder back together to complete the new battery installation. Start by replacing the white plastic disk, followed by the protective black rubber disk. Use your small metal tweezers to replace the small watch springs in their correct locations. Replace the back cover of your Casio Pathfinder, insert the four screws and tighten them with your optical-sized Philips screwdriver.

    Mitsubishi convergence IC replacement: this applies to sets that use (2) STK-392-570

    The Idea here is to get the Middle Circuit board out so you can replace the Convergence Ic’s.


    HERE is what you will need: (most of this you can buy on the internet or at local electronics stores)

    Two new: STK-392-570 CONVERGENCE IC’S
    One good soldering iron
    Solder
    De soldering braid or wick
    Liquid flux
    Heat sink compound (grease)
    Denatured alcohol
    One short Philips screwdriver
    One small clean toothbrush
    One electric screw gun to REMOVE screws

    Turn the set on and examine the picture for how the Convergence looks bad---when you are done examine it again---once in a great while you will get and install a new IC that is bad. Remember this when you have finished—if the convergence is still bad but different from what you started with you may have installed a new I.C. that was bad. Turn the Set off.


    1. Unplug set.
    2. Remove back cover.
    3. Remove front speaker grill and inspection plate behind it.
    4. Remove the 2 or 3 black screws that go thru the back edge of the plastic frame that hold the chassis down.
    5. Where all the video and audio jacks are on the right edge of them you will see a diagonal plastic (Black) remove the two brass screws from the outside edge, remove another to the right bottom and a third smaller screw forward and to the left; remove plastic piece and all four screws and set them aside.
    6. Look carefully at main board in center of the set.
    7. You will find a number of screws hold it into the plastic frame.
    8. Towards the left back edge of this (to the right of the plastic you removed) you will find a metal cover with a small screw on either end. It has a lot of round holes punched in it.
    9. Remove both screws and pull the shield up and off---remove the board beneath it by releasing the two tabs on the bottom right side and pulling the board out—handle it with care as it is the digital convergence board that stores the set’s memory of adjustments. Set it aside
    10. At this point you need to pull the entire Chassis back at least a few inches---If it does not slide back look for a plastic latch on either side near the front of it. Some sets have the latches on the left or right side—black plastic tabs that lift up.

    HD image has lost sharpness


    You will need to replace the convergance IC's if the colors are no longer lined up and they won't line up using the tv's controls. Also, if the crt lenses have a lot of dust on them removing that will help the sharpness and brightness of the picture. Don't use canned air. Get a crt lens cloth.

    Replacement of Toshiba Satellite A135-4427 screen


    • First, purchase your replacement LCD display for your exact model of Toshiba A135. I found mine for about $110 with shipping.
    • There are five screws hidden beneath rubber bumpers around the screen. Carefully use a small flat screwdriver to remove the pencil eraser sized rubber bumpers - one at each corner, with the fifth at the top center. Make sure you carefully remove the sticky stuff they used to adhere the bumper to the screw as well. Set these carefully aside.
    • Remove the five screws and set them aside.
    • Gently press down at the inside plastic frame until it pops out slightly. Gently press towards the center of the screen at the sides of the inside plastic frame until it pops out.
    • Carefully separate the front and back plastic shell around the screen. Set the front plastic frame aside. You may need to loosen some of the white tape used to keep wires attached to the rear plastic shell. Gently lower the rear plastic shell away from the LCD, but leave as many wires attached as possible.
    • On the back of the LCD there is a large cable. Carefully pull up the tape that holds this cable in place and pull the cable down to remove it. You will also have another piece of white tape on the back of the LCD to peel back. The tape is important - don't tear it or get your fingers in it to remove its stick!
    • At one end you will see a set of a few wires plugged into a piece still attached to the rear plastic shell. Unplug this.
    • No wires should still be plugged into the LCD anywhere at this point.
    • Around the LCD there are six small screws. Remove these and set them aside. You now have now removed the old LCD.
    • Reverse this process to re-assemble.
    • You may want to use some blue LockTite (which can be found at hardware stores) for the screws as you replace them. Additionally, you might need a little rubber cement to re-attach the rubber bumpers at the last step. If you do not re-attach these bumpers, your screen will quickly become scratched by your keyboard touching it when the lid is closed.
    Good luck!
