You got to remove the lower back panel and you'll find another 4 screws there and don't remove the front cabinet with the screen, remove the back one with the mirror. I sugest you to use the old deflection yoke, in case your new crt is comming with his yoke.

Require copy of the installation instructions so as to remove unit from vehicle -- unit came with vehicle: have no knowledge who installed this unit


  1. If there are any visible screws from the outside of the unit, or from the inside of the unit when the screen is folded down, be sure to remove them first.
  2. The unit should snap off from the sides, be careful not to break the clips.
  3. Disconnect the wires from the unit, and continue to remove the base plate attached to the ceiling of the vehicle.

My lens wont go back in and it also wont turn on...


Dear Community members!
I really know how to fix this problem "stuck out lenses"-i have done the repair myself,it needs some patience,and time. It takes 1-2h if you have good mechanic-electronic skills maybe 45-Min,for me this was 1h.I would like to mention, I am IT-electronic service engineer,but anyone with good,steady hands and some skills can do it,just needs little bit of patience. You have to take pieces all the camera, unfortunately.
1.Remove the external casing unscrewing all the visible screws 2.With the cover removed flip the screen out,be carefully because this is attached with two type of connectors witch are very delicate! 3.After removing the screen you have to unscrew the 6 black screws and the CCD-sensor comes off.Very carefully!!--it has 4-springs attached and 3silver screws are holding it and of course the wiring which has a delicate connector which needs to be removed as well.Underneath of this you should be able to see the lens moving mechanism which needs to be reseated,in mine one i had to remove on of the springs from inside and reseat a plastic pin which holds the mechanism arms. That's all. 3.After that everything needs putting back in reversed order. Good luck!

The tip of my AC charger broke off on the contact post of my samsung sph-a620. A new charger cannot make contact for recharging purposes. I cannot see how to disassemble the phone to access that electrical...


Hello,

To disassemble the phone, you need to get he appropriate screwdrivers and follow the processes below;

  1. Turn your phone over so the battery cover is facing you. Remove the battery cover and battery. Next remove the 2 rubber stoppers and unscrew the aerial.
  2. Remove the screws,
  3. Next remove the 2 rubber stoppers & screws above the main screen,
  4. Prise the back part away from the rest of the phone by running your fingernail between where the two parts meet,
  5. Unclip the ribbon,
  6. After removing the ribbon cable, carefully lift the metal part. Another ribbon will be attached which should be carefully removed. Take the circuit board & keypad out and you'll be left with just the screen and the keypad rack.
  7. On the circuit board, you'll see the charging port and the broken charger that is in it.
  8. Try to pick it out with a pincher, and if you cannot, then you have to replace the charging port.
  9. Disconnect the charging port and replace it with a new one.
  10. Reverse the process to reassemble the phone back together.

  11. Take care.

How do I open it to look inside?


First, lay the tv/monitor on its screen on something level and soft as not to damage the screen. Remove any visible screws that seem to attach the base to the unit. Some models you have to look under the base for pins orso to push together to slide the base from the stand, only then you could reach the 1 screw holding the monitor to the stand....Once stand removed, remove any screws you see holding the monitor casing together, usually only a few screws since they are mostly held together by plastic "clips"...Once screws are removed, then gently insert a flat(screwdriver orso) inbetween the case?housing, repeat this all the way around the case/housing till completely loose....You will prob have a few wires or maybe a ground wire that you would have to remove before completely being able to seperate both sides(front case, back case)..Sometimes you might have to unscrew and remove the skinny washer/nut around the cable input orso..
Good luck!

Finepix F40fd: Need instructions for changing LCD screen


Remove the battery and leave the door open. The door operates a micro switch to shut power off to the camera.
Once you have a tri-wing screw driver start by removing the three tri-wing screws first. These should be located on the side where the hand strap is attached. Then you can undo the rest of the screws ( 5 on the bottom and 2 on the other side). Now pull the cowl away from the side of the camera with the hand strap. It should just unclip when you pull it. This should reveal the side of the two outer cases. The rear case is still attached on this side by a small screw and two more on the top by the zoom / picture button. Once these are removed lift the rear case up from the other end first so that you can release the ribbon for the keypad or just flip it over so that it lays flat next to the camera but still attached by the ribbon. the screen should now be visible but you may have to flip this over so that you can remove the bracket for the screen (the socket is visible underneath it and you can remove the screen with the bracket inplace but I find it easier to remove the bracket).
Be very careful when you lift the bracket clear as it is close to the flash and while the camera is off (and with the battery removed and the door open) the flash is still charged and can give quite a shock!
Now all you have to do is release the locking tab on the socket for the screen and remove the ribbon and then replace with the new one. Then reassmble the camera

PSU connector on the mainboard


Not sure about that brand but the normal process for removing the back on a lappy is:
Remove all screws on the bottom.
Remove all covers and cards and put them safe
Remove battery rom and hard disk
Remove panel above keyboard and screen hinge bracket cover if any
Remove keyboard
Remove any screws from under keyboard that hold chassis
Remove screen bracket screws and connectors from screen.
Remove screen off chassis.
Remove any visible connectors that will get in the way when case is separated.
Separate case making sure no cables are caught.
Remove screws holding in motherboard
Remove motherboard
Turn over and resolder joints on the bottom of connector if plastic is in order.
Reverse the procedure for assembly.
Its not a very easy repair an experienced tech will take about an hour maybe a little longer to do it.
If your memory isnt great take photos along the way, makes for easier assembly.
Good luck

HOW TO OPEN TV


try taking the fake "lug nuts" off the tires with a set ff channel locks. Just pry them off easy. There will be 2 or 3 screws holding the wheels on. Remove the wheels and take out the visible screws there. Then remove the 4 easy to see silver screws underneath.

Hope this helps
