If you see a white outline of a semi circle it is a pressure mark caused by something pressing down on that part of the screen. Nothing can be done except to replace the LCD if it bothers you. Good Luck!

Schylling child's safe my son lost his combination

My sons is 34, 43. If that doesn't work, pry a corner of the door slightly open so you can see the lock on the other side of the door. You'll see 2 metal semi circles keepin it locked. Then turn right until the flat part is facing left, then turn the knob left until the 2nd semicircle's flat part faces left and the door should pop open. Hope that made sense.

My aurora 440 screen goes blank when I stop sewing, I have to switch off and switch on again for the screen to come on again with the stitch size

I'm not exactly sure what the symptoms are .... do you mean that you can sew a long line of stitching without problem and then when you stop sewing, the machine turns off ? If this is what's happening, it could be a problem with the main motor drive circuitry ... when you stop sewing, there's an electronic brake that stops the motor in the right place and it sounds as though this has gone faulty and is killing the power supply. Unfortunately, if this is the case, your machine may well need to have its main control board ('S'-print) replaced, which is not cheap (check your warranty). Check the machine again, exactly what are the symptoms ... sew-off a reasonable length of material on a short stitch-length and check whether the machine 'dies' when you take your foot off the foot controller. Also, have a look to see if the sewing light and/or display backlight are still on when it has died.One other thing you might like to check is that there are some indicator lights that show whether the main power supply is OK and the processor is running .... these lights are behind a 'door' on the front panel ... you're probably not even aware that the door is there. If you look on the left-hand-side of the upright part of the front panel, to the left of where it says 'Quilters Edition' and about halfway between the base and the sewing arm, you'll see a thumb-sized semi-circle in the plastic, that is grooved ... look closer and you'll see that the front panel below the silvered part is a 'door' in the front panel and this semi-circle is the release for that door. If you press firmly on this semi-circle, whilst pulling the left-hand edge of the door with the big 'QE' on it towards you, it'll come off ... you do need to press the semi-circle quite firmly to release the cover. Behind the door are a set of 5 yellow LED indicators - the top four should all be brightly illuminated, whilst the bottom one should be flashing. If you repeat the sew-off, note whether any of the LEDs goes out, or goes dim (particularly the one labelled 30v - this is the motor supply voltage). If the 5v LED goes dim, this might be a fault on the power supply module ('L'-print), which is alot cheaper to repair than the 'S'-print. To replace the door, just re-insert the two lugs on the right-hand-side into the square holes in the front panel and push it back in place until it clicks firmly back. Good Luck, but be aware this may mean a trip to your Bernina service agent. Get back to me with the results.

A blue semi-circular hue on the bottom left of the screen

9 times out of 10 the Blue Polarizer heats up and discolors which causes that problem, all projector's have the same issue and have for years. My professional recommendation is get in touch with Sony, they have been extending the warranty's for this issue. If they won't the have a servicer replace the light engine of which is not cheap.

Fitting instuctions for replacing lcd screen on my samsung e250 mobile phone

1.take off battery cover, remove battery, memory card and sim card
2. remove the five screws on the back... two at the bottom, two in the middle and one on the mid top right and take off this cover, remember! keep the screws safe
3. slide the phone up and take out the two screws on the left and right paralel with the battery tabs then remove the two screws ether side of the camera...they might be covered by rubber coverings, these pop out easily you can prise the top of the screen off with a small flat headed screwdriver
5. its conected to a ribbon cable, remove the tape and slide out the cabble from the screen.
6. now take out the screen PCB from the plastic casing and replace it with your new one and put the ribbon cable in and clip it back together, now reverse stages 3 to 1 to put it back together.
7. if the ribbon cable is attached now you must look at the PCB board on the back for a square copper line, on the left of this there is a big black square just smaller than the copper square, prise this off with your finger nails, keeping it to the side take the PCB up about 2mm and then fold the bottom of it to revele it is conected to a ribbon cable by a bigger version of the black square so prise this off and take the PCB and put it safely to one side.
8. look on the front of the phone under the top bit of the screen, there should be a semi circle in the plastic with a black circle in the top of it, use your nail or a flat headed screwdriver to pop it to the other side of the semi circle, now the slider should go past what it used to o you can slide it up to when you can see the ribbon cable go down through the phone, now push the black square end through and you should be able to slide the whole front off.
9. replace the screen by taking the screen PCB out and repacing it, then thread the ribbon cable back through and slide the front on while making sure the back circle goes into the semi circle and to the top side of it, then thread the black square through the phone to the front and clip the phone front back on.
10. snap the black square back on to the back Circuit then put the circuit back into the phone and snap the small black square back on then go from stages 3 to 1 to put it back together.
this should be fairly easy to do for most people.

Green semi-circle of lines on Samsung 55" HDTV (projection)

I believe i have the same problem myself. When my TV is on any of the Component Inputs without my DVD player turned on i usually get the normal green screen. But now that is a dip in the green at the top of the screen from the top left to almost the top right and black pushing down on the dip. Almost like a green curtain was sagging at the top and you can see the black behind it. It does this on every input and distorts every picture you see. The distorted picture has all the green slightly off from where the rest of the picture is and where the dip at the top of the screen is there is somtimes purple instead of black.

I know the basics of how the picture gets onto the screen and its my guess that the Green "gun" for lack of a better term and somhow come loose, or been missaligned to a great extent. I would love to find an answer to this problem, and anyones best guess as to how much a repair man will charge, just so i know the ballpark.

Blue patch on left side of screen

I had the same problem with my Hitachi PJTX100. I discovered that there was considerable dust build-up inside the unit, causing insufficient venting of heat which then damaged the color prism/filter. It was close enough in time to the warranty for Hitachi to cover parts replacement (approximately $1,600). Since the repair, the blue patch is gone. I also regularly vacuum not only the outer cover but also the inner air filter that easily snaps on and off.
