SOURCE: HI I have a Samsung LN-T4661F

Is it like this?:
http://i691.photobucket.com/albums/vv275/oldskewel/samsung_LNT4661F

I think I have the same problem on my LNT4661F. I happen to also have a 4061F and just temporarily swapped main boards, which confirmed that it is NOT the main board which is bad. Swapped LVDS cables to confirm that's OK too. If you replaced the T-con board, then that leaves the power board or the panel. Did you make any progress on this?

All the caps on the power board look good, but I hear a whistling noise from one of the power transistors.

Negative/inverted pictures


If the images in the camera are inverted , then could mean repair or replacement is the remedy and I suspect only replacement will be the answer.
When you say Photo Gallery- do you mean as displayed in your computer after uploading?
If so then an image editor such Irfanview or Picasa will revert them.

I have an LCD TV. All of a sudden the picture colour has gone wierd. The best way to describe it is that it is similar to either a colour negative or one of those scientific 'false colour' images. This...


TFTs can produce a wide array of colors, but it takes an enormous number of transistors to make up a display, and a problem with any one of them creates a defective pixel on the screen. Typically this shows up as a bright spot on a dark background, caused by a damaged TFT failing to turn off a pixel. Most active matrix displays contain a few bad pixels, but a few bad pixels are not going to have much of an impact on the overall picture.
The properties of liquid crystal material can create problems with viewing angle effects, causing the image to darken, disappear, or reverse the dark and light tones when the viewer is not directly in front of the display (kind of like looking at the negative of a photo). The light bulbs make LCDs heavier than the plasma TVs (though they are still lightweights compared to CRT televisions.
Benefits of LCD TVs include a picture that can't burn in and doesn't deteriorate over time. Because of their flat-panel nature, placement options are plentiful, optimizing the cool factor over standard TVs

My scanner doesn't scan negative


" I can only select platen as the sourc. the film setting has vanished" - I had the same problem. Unplugged the USB cable from a shared usb 2.0 hub and plugged into an old USB 1.1 dedicated port and it started working. No ideas why (perhaps in the hub it couldn't detect the scanner model correctly)
