I am unable to close the driver door. The metal piece in the door that wraps around the screw looking piece located in the door frame will not engage. Help...

Open the door & have someone hold it open,
with the door handle pulled out

Use a screw driver or any round tool to open the
plastic lock catch in the door latch

Sometimes your clothes catch it & close it ,as if it
were wrapped around the B-Pillar Pin, your referring to

How do I adjust top and bobbin tension on Viking emerald 183?

I don't own an Emerald, but I am pretty sure there will be a button for it. It is usually represented by what looks like a twisted strand of DNA. The adjustment will be shown on the screen. I just had a look at the Emerald promo video from Husqvarna, and could not see the button on the green control panel. Is it one of the buttons closer to the needle? I was unable to see those closely.
You will be able to completely remove the bobbin and the bobbin case. There is a small screw on the outside of the bobbin case just near the tension spring (which looks like a thin flat piece of metal). You can adjust bobbin tension by turning this screw - right for tight; left for loose. Imagine the screw head as a clock face and never turn the screw more than 5 minutes at a time. You might like to use nail polish or whiteout to mark where the preset default tension is (mark where the cross piece of the screw head is) so you can return there later.

I connect my B130 to an external display using a vga cable. Both screens work. But I am unable to turn my laptop's screen off using Fn F8

the screen wont go off unless you use a docking station. Once you are docked, you can close the notebook lid and use the machine like a desktop: with all your cables hooked into the station itself.

I know this is an old thread, but hopefully this will help someone! The problem is the DMD board is knocked out of alignment. It is adjusted by removing the small cooling fan and loosening the three gold screws that hold the assembly in place (two on the left and one in the middle of the board) AND by loosening the three (or four) spring loaded screws in the middle of the heat sink. Display a test pattern (from the service menu), tape the interlock switch closed (so you can power the set with the back off) and then carefully move the assembly (down is up; left is right.) An assistant helps! Once the image is correct, snug the screws up (they don't need to be torqued down!)

It took me FOREVER to figure this out - hopefully this will help someone else a little faster!

Can't Close...

Hiya. It is possible to fix so long as it is not caused by the laptop warping slightly. If it's the teeth that have broken then you need to replace that part - it's not particularly easy to do tho and normally means taking the screen plastics off. Any computer shop could do this - at a price. Alternatively you could buy the part from Ebay and do it yourself for less than £10. It's a matter of removing all the screws on the front of the screen (often hidden under black covers). Splitting the front from the back casing - carefully because it is easy to crack the thin plastic, and watch that nothing slips out of place (you want to see how it comes off so you can put it back on the same way). The clip may just sit there or could be screwed in position. Replace the part and reverse the order to get everything back. Lots of fiddly work and not worth the trouble unless it is really being a nuisance.

The teardown information from rbrown67 was very accurate and easy to follow. It helped tremendously in tearing down my machine to replace the AC plug.

RAZR V3M thinks it's always open - Screen will not turn off

in the top right corner you are suppose to have a little circular magnet that changes the screen when the phone is open or closed. I just changed my housing yesterday and took the magnet out and put it in my new housing but for some reason i have the same problem as you. so maybe you lost the magnet when you replaced the lcd and if that is the case then you are screwed. try have Motorola fix it, don't tell them you replaced the lcd

Screen light go off but image still on.

You will probably need to remove the bezel and key board to see or get at the nuts on the back of the screws. When you get this far you should be able to see the problem with the wires or backlight. Probably where they flex when you open / close the lid. Undertake any of this at your own risk. Do not force anything. Stop and look for "hidden" screws. A new standard fan would be your best allover option.
