The focal length set on the camera is wrong. If you are using the TCON series extension lenses the focal length needs to be set at full telephoto, 36mm.

Sharp LL-151MU - Image turned black and white and flickers with a checkerboard like grain to the image. Any one know what area of the circuit board this may be?

It could be connections to the panel via the flat cables or the LVDS cable that goes from the main to the Tcon, or it could be a bad Tcon

I have a Vizio E701i-A3 Edge lit LED TV. I looks like an 8 inch strip of the LED edge lights along the bottom are not working. Do I need to replace the light or the T-con?

Tcon is the board that sets the tone for the whole image. If you have a small section that appears to have no backlight then the tcon is not your likely point of failure.

I've cleaned the glass and still have a black line on the image

Scan a document in 300 dpi in full width. Check where the line appears in the image. For example if the black line appears at vertical position say 1900, then it means the dirt is at 1900/300 i.e., 6.3 inches from left. Clean the area thoroughly. Check if any pin had created a scratch in the glass. At different contrast levels, if the line appears different, it is definitely unclean glass. On the contrary, if the line appears constant at various levels of contrast, then it is possible that scan module is faulty.

Ds lite case repair

Ok i can tell you how to do this.

First of all you need to make sure you have a new shell and the tools needed for the job, listed below.

  1. NDS screwdriver - $9.99
  2. #00 screwdriver - $9.99
  3. small pair of adjustable pliers (for replacing case).
  4. Soldering Iron (required to replace top display screen or case)
image 1.

OK. Look at image 1 above. Remove all the screws circled.

if you need to access the top of the DS Look at Image 2 below & remove those screws.

Image 2.

*Tech NOTE * Be careful not to lose ur shoulder button shaft and springs (Image 3 circled in RED) they will come out on you.
Also you will see a small cable circled below in Blue (image 3) Only remove this if you absolutely have to, this connects your display touchpad to your motherboard and can be very difficult to reinstall.

Image 3

Their will also be a white cable (not in pic) this can be unplugged by lifting the little round connector with your fingernail; allowing you to pull it through the hinge.

If you unplug the Black cable and pull it loose, you will definitely have a difficult time getting it back underneath its socket. It's easier to desolder it from the board in the top case ( Image 4 in green)

Image 4

I know this is a lot, just bear with me we're almost done.

This next part you have to use EXTREME CAUTION

To unplug your display cables (image 5) you will have to very carefully lift the little black latch on the connector. You will have to use 2 fingernails, one on each side, to lift these off. IF you only lift from one side you will break the Black latch on the connector making the entire board - garbage! Same for reassembly - be wary pushing the latch back down. The top cable circled in Red is for the bottom display. The bottom one is for the top display. There will be a single screw holding the MotherBoard in place. Remove it and lift the MB out carefully.

Image 5


Above (image 6) is the Bottom display assembly. The 3 pieces are held together with adhesive. The display is on teh bottom, the Touchpad in the center, and the top is the protective shielding. They can be pried apart carefully using fingernails or a plastic tool (be very careful not to crack anything)


Image 7 is of the top display. Where you see the green circles is where the screw covers are located. use something very small to pry them out. Remove the 4 screws.

Hinge Removal - Image 8

Remove the two screws circled in Image 8 to get the hinge apart. If you are replacing your top display this will greatly help when you are trying to fit the cable back through the hinge hole. The Top can now be safely removed
Fitting your new cable through the hinge hole can be a bit frustrating. make sure you have separated the top & bottom cases to give yourself more working room. Remove the black and white wires, just out of the way. The cable will go into that thin slot a bit. When you reassemble it make sure to roll the end evenly from top to bottom first. This will help get it through the hole. Then put the round metal ring on afterwards, lastly put the wires through.

your speaker wires are soldered to your top display. To replace the case you will need to remove the wires to go through the hinge, and to replace the display you will have to remove them also (image 9)

Image 9

**Tech nOte**
when reassembling the top and bottom shell take note of the on / off button and the switch. Make sure you line the switch up with the button or you may break it***

Image 10

Image 10 - note the black wire that goes through the hinge. It is "jumped" (meaning it is connected to two places on the board, one next to the other)

Image 11

Image 11
The collar that fits inside the plastic case hole.

Image 12

Circled in green in image 12 is the angle adjuster. This is best installed with a small pair of adjustable pliers.

WOW... we're done!! As far as I can see this is a complete breakdown for anything you would need to fix. I hope this is a great help to you.

Please Rate highly if this helped you
