There are hidden hooks (catches) all along the edges where the front half and rear half of the case meet. Using something like a putty knife (something thin but very strong) put the tool in the crack between the halves. Start near the center of the top or bottom edge and carefully separate the halves. It takes some expereince, but you'll soon see the hooks and figure out how to unlock them. Then you place another tool in the gap you've opened so it doesn't relock, and continue working your way around the edges. Until you have more experience and figure out how to do it with only one tool, you should have a few or even several similar tools to hold the opened areas while you're opening the next one. Once you have three sides unlocked, you can pull the two halves apart. I appreciate your thoughtful rating.

How to disassemle garmin 4208


If you have the correct soldering equipment and have the replacement part, it shouldn't be too hard. You'll need a jewelers screw driver to get the small screws out. Use a guitar pick to pop open the case. Work it around the case until the back half separates. Clicking and popping sounds are normal. Take out the battery wires. Do NOT yank on the wires... gently grab the plug and wiggle it loose.Remove the screws holding the board to the case to expose the solder side and remove the broken power jack.

Wash load almost complete, buzzer went off, door locked & won't open. Lights all blinking. Unplugged washer, plugged back in, lights still blink, door still locked.


Hi,

To open the door first unplug the machine then take off the front panel under the door (three screws at the bottom) reach in by the door lock and there will be a plastic tab hanging down, that is the manual release for the door. Pull it down and the door should open right up. I'm judging that the machine is flashing a code when it shuts down, often times its F11 or FdL in either case the problem is most often a bad CCU circuit board (whirlpool had quality control problems with this circuit board) There's what's called cold solder joints on the board at the points where the spade connectors and relays (5 of them) are supposed to be firmly soldered to the board. These bad connections cause the Duet washer to have all kinds of issues. To repair it you need to take out the CCU circuit board It's in a plastic case at the inside, top, back of the machine. Remove the case as a whole, it's easier that way. Then remove the circuit board and touch-up those points I mentioned. If you not good with solder techniques you can remove the board (keep it in the case) and take it, and this response, to a good appliance repair shop and they should be able to help you out. Good luck.

Sony vaio desktop all in one back light not working


To fix your problem please follow the below given steps
Step1
Power on your computer and wait until there should be an image displaying on your LCD monitor. Look directly into the monitor from a distance of about 1 inch way. Cup your hands around your face to block out the light in the room and get a clearer view of the LCD screen. Check to see if there is a faint light visible in the screen, which will indicate that the cold cathode backlight has gone out, or no image at all, which will indicate a different problem.

Step 2 Check the manual that came with your desktopmag-glass_10x10.gif LCD monitor or navigate to the manufacturer's website and find the model of cold cathode bulb that the monitor uses as a backlight. Purchase a corresponding replacement bulb

Step3 Power off your computer and then remove the monitor cable from the port on the back of the computer case. Disconnect the monitor stand from the monitor either by pulling out the plastic latches or by removing the screws holding it to the monitor's casing.

Step4 Lay the monitor face down onto a stable work surface such as a desk or table. Take out the screws along the edges of the monitor's casing and set them aside. Lift the back side of the monitor case off of the monitor and set it aside. Check to see if your model of LCD monitor has the back light directly exposed on the lower end of the monitor or if it is hidden behind another plastic or metal piece.

Step5
Remove the screws holding the plastic or metal piece over the bulb if there is one present and set the piece aside. Check to see if your model of monitor keeps the bulb in a plastic casing or if it is soldered directly to the metal. Use a soldering tool to remove the solder or instead use a rotary cutting tool to cut into the clear plastic casing around the bulb if it is inside a case.

Step6
Slide the new bulb into the open spot on the monitor and either solder it in place or use a piece of tape to cover over the opening you made on the plastic casing with the rotary cutting tool. Place the metal or plastic cover back on if there was one and reattach the screws. Set the casing back onto the monitor and place the screws back in.

Step7 Put the stand back on the monitor and then reconnect it to your desktop computer. Power the computer on and wait for an image to appear on the screen to make sure the back light bulb was installed correctly.

Please rate me if this solution works for you

Thanks......Have a great time.

    Cant use my adaptor


    this seems to be a common problem. I have some experience soldering, so I opened up the case and replaced the part with a Radio Shack DC jack, soldering the tabs to the motherboard with insulated wire.
    If you know someone who can solder, this isn't that hard a fix, once you figure out how to open up the case (in addition to the screws visible outside the case, there is one underneath the keyboard. Remove the faceplate over the speakers/HP Now buttons, then you can remove the keyboard.

    Broken the mains power cableand dont know were to get a new one


    Help is at hand. but you do need basic electrical skills for the first solution and handy soldering skills for the 2nd.

    If you cable is fraid then cut the cable and fit an inline connector. If your not sure here is a link.

    Total replacement of power cable and plug. you will need to buy new flex and plug. normally two core flexible (multicore not solid core) cable.

    Open up the rear case to the tv and keep all screws. DO NOT touch the end of the tv tube as high voltage lingers a while after unplugging. You are looking / tracking the power cable where it fits to the tv motherboard.

    Take a standard solder iron and remove each cable in turn. noting the colour and positions. Prepare your new cable feeding it into the casing and motherboard to suit. Apply flus and solder to secure each new cable in place. Hold cable while it sets and cools. CHECK there is no solder connecting these cables together for obvious reason these DO NOT connect together.

    Replace casing and all screws in reverse order.

    You should have a good to go new cable and a tv working fine.

    I have a vaio pcg-7l1m which will not power up. Have checked adapter and it's fine. Would like to open laptop and see if input is loose. anything I need to know about getting case open? Having opened other...


    Hello,

    When you say you checked the adapter, I assume you mean you put a meter to it and it is giving 18-19 volts. I also assume that no power means no led's, no fans, no nothing.

    Before you tear it apart, please try the following to try and get some signs of life.

    Remove the battery and try to boot. Leave the battery off for the rest of the testing. Remove the hard drive, and the optical (dvd) drive. There is likely a screw on the bottom that will release the optical drive. Try to boot. If no good, remove the ram and try again. The ram stick(s) are located under an access panel on the bottom of the laptop.

    If all this produces nothing, your last effort may be to resolder the dc power jack on the mainboard. This is not that difficult but you need to be careful while doing this:

    I like to keep two separate containers for screws...one for those from the bottom, and one for those from the top. If you own a video camera, maybe video the laptop as you do this. It could be a valuable reference when re-assembling it :)

    First, remove the access panel from the bottom that provides access to the wireless antennas (2 wires). Pop the connectors off of the wireless card. You must do this to remove the display, as the wireless antennas are in the display. Next you need to remove the top bezel (strip of plastic above the keyboard. You may need to remove some screws from the bottom to release it. Gently, insert a small flat head screwdriver under one of the hinge covers (plastic bump over hinges) and pry up . Usually it is just plastic clips holding it on and it will pop off. You should be able to remove the bezel easily.....gently, remember? With the top bezel off, you can remove the keyboard (may have screws on the bottom holding it, but likely not. Remove keyboard screws on top, disconnect the ribbon cable and remove the keyboard. Now, snake the antenna wires that you removed earlier up through the top of the laptop. Remove any connector cables going from the display to the laptop. Remove the hinge screws holding the display on and remove the display. There might be two screws on the bottom securing the display as well.

    Now, remove all screws on the bottom of the laptop and try to gently pop the plastic case apart. There may be screws under the keyboard (on the top side) that hold it together too. Take your time here, paying close attention to any connector wires....BE VERY MINDFUL OF TINY WIRES AND CONNECTORS.

    Once you get the case apart, there will likely be a few screws securing the mainboard to the plastic case. Remove these (circle the empty holes from the screws with a marker so you know where they go back in)

    With the mainboard out, locate the dc power jack. It likely has 3 or 4 solder joints securing it to the board. With a magnifying glass, inspect the solders for cracks in the solder joint. If they are cracked, that's likely the issue. If not, resolder them anyways. Using thin electronic solder wire (do not substitute with plumbing solder) heat each solder joint, and apply a SMALL drop of solder. Not too much, or it can run down into the connector and bugger things up. Be careful not to touch/heat up any other components near the jack too.

    With this done, dry fit (without all the screws) the laptop back together. Make sure all the little connectors have been re-connected and while thinking happy, positive thoughts, try to power it up :)

    If this won't get it to power up, then you likely need a new main board. If you can't find one for a reasonable price on ebay, get a new laptop. In my experience, Sony will not sell a mainboard to anyone other than an authorized Sony service shop, and even if they will, it will likely cost $400 or more.....too much to spend on a part (likely refurbished) with a 90 day warranty.

    Hope this helps! Post a comment and let me know how you made out.

    I need to open my Acer laptop case to solder to power switch


    Hi there,
    this may not be your exact model, but should give you a good general idea on how to get inside. The key is prying up the top strip, that seems like it is going to break. Use something plastic or wood if possible. A screwdriver will leave marks.

    Casio CTK-541 Keyboard AC Housing


    Many people have damaged ac power prong problems. Tools required is a soldering iron and solder wick or a bulb desoldering device . Next you will need Jamesco part no. 101178. This part matches the motherboard part in size and function.

    How to : After removing all case screws open case from back. There you should see motherboard. You should desolder the power housing before you remove motherboard screws. (It is easier). After desoldering the power housing remove motherboard screws and gently loosen mother board. You should be able to remove power housing from board (caution if it sticks try remong more solder). Put in new part secure in place and solder (I use tape to hold in place) . AS a note once the motherboard is secured close key board and check for funtionality before puttting all those in place
