Question about Epson PhotoPC 3000Z Digital Camera

Bad Pixel in LCD (not CCD)

Ust received my 3000z from Buy.com, and lo and behold, the LCD (not the CCD) has a dead pixel that always is red. This became imediatley evident when in any menu (either blue or black background). It's only one pixel, but that is one too many. I am sending it back for a new unit. I saw the other thread (BAD PIXEL) but that seemed to do with CCD pixels, not LCD pixels. Are others getting cameras with dead LCD pixels? I hope I only need to send bacl one camera, not several.

My camera also has a one bad pixel in the LCD; my pixel is green. My camera was also ordered from Buy.com. They have been very helpful and my story is almost identical to yours for their return/replacement practice. It is really nice to see online companies that continue to offer 'great' prices and also provide great customer support.

Why the white or black spot on LCD Display

Dead and Stuck Pixels <br /> Pixel defects for an LCD monitor are defined as one of two types: dead or stuck. Technically, both types of pixel defects are stuck pixels but it really deals with the electrical currents and the state of each pixel or sub-pixel. <br /> A dead pixel is defined as a pixel or set of sub-pixels that has failed and is permanently in the off position. This condition means that the pixel will not let any light through. This can be observed as a dark or black spot on a brightly colored or white background. <br /> A stuck pixel is defined as a pixel or sub-pixel that has failed and is permanently in the on position. This can be either with a single or multiple sub-pixels for a given pixel and is best observed on a dark or black background. A white pixel means all three sub-pixels have failed while a green, red or blue pixel means one of the sub-pixels has failed. <br /> Hope this helps, if so do rate the Tip

Is it true that when one pixel goes out, others are soon to follow?

No, that's not true at all. Each pixel is its only little device - one pixel does not effect another. The pixels work together to make a picture, but are all controlled separately. If your pixel is "stuck" and not dead, then you may be able to fix it! A stuck pixel is red, blue, green or white, while a dead pixel will show up as black. Sometimes a stuck pixel can be fixed by covering a pencil eraser with a cloth and pushing down on the pixel gently while the TV is on. So, in summary - no, one bad pixel doesn't mean any other pixels are bad. Hope that helps, Alex

What does it mean by dead cells?

I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

Jvc hd7. there is "one" pixel "dead".

I don't know if its from the CCD or from your LCD Monitor. CCD dead pixels can be fix but you can't do this at home, need service center because first you gonna need Service Support Software, second you need connecting cable(QAMxxx) and (YTUxxx) Jig. Sorry

Blue vertical line

The lines appearing on your LCD means it has a defect on the screen.

There are 3 types of pixel defect
1) dead pixel - pixel is always off
2) stuck pixel - pixel is always on
3) hot pixel - pixel is on but in red, green, blue or yellow, can also be a light black color

You can try to fix stuck or hot pixels but dead is dead.
1st method, flashing different colors rapidly:
JSScreenfix.com has a great tool. This is their free java applet or you can download it below.

2nd method, applying pressure to pixel:
Damp paper towel, Small stylus or dull pencil.

3rd method, tapping the pixel:
Pen with cover on or another small, blunt object.

If your laptop is still under warranty, get it replaced. If not you are looking at the most expensive part in a laptop to get replaced. (LCD screens on laptop is roughly equivalent to 40-60% of the total laptop cost

Dead pixel

Dead pixels cannot be fixed, each pixel is controlled by a transistor that is part of the LCD screen. If it is bad, the only option is to replace the LCD screen.
