My mfc240c says to replace the yellow ink cartridge but I don't want to spend money on that if the 'light bulb' is ruined. When I turn on the machine, I don't see any light for scanning or copying. ...


By the "light bulb," do you mean the scanner lamp? That lamp should only turn on when you are actually scanning, faxing, or copying a document. You should be able to still use the machine to scan and fax, even with the yellow ink empty. Try scanning a document to see if the scanner lamp comes on.

As far as printing or copying goes, you won't be able to print or copy anything until you replace the yellow ink, even if you try printing in black and white only.

Canno turn the tv on.


You probably have a main or high voltage power supply problem; the latter produces the 20,000 plus volts for the CRT and gets its voltage from the main supply. It's difficult to say which is at fault without a few measurements.

Black and white negatives produce scans that show too much contrast......any suggestions?


1) Decide which problem is the worst: shadows too dark or highlights too light. 2) Run your scan with Nikon 4 software tool "Digital DEE" adjusted for EITHER Shadows or Highlights (not both; Highlights setting will "trump" a Shadows setting, even though you have a non-default setting at all DEE sliders).  Generally good choices for Shadows are 39 to 55. (39 = lighten the shadows a little; 55 = lighten the shadows a lot.) Experiment; do several scans. Generally good choices for Highlights are about 17 to 42 for amount and about 4 to 30 for threshold. (17/4 = dim the highlights a little; 42/30 = dim the highlights a lot.) Again, you have to experiment to get some experience. 3) When in Photoshop PSD format (After first doing a Levels adjustment): Try using the Adjustments/Shadows and Highlights tool to AGAIN brighten your too-dark shadows and/or tone down your highlights. (I.e., the effect is cumulative on top of your Digital DEE effect. But Digital DEE is a more "magical" feature and is somewhat preferred to PS's Shadows and Highlights tool. DEE, however, will often produce an annoying "light smear" [bright area "dragged" into an adjoining darker area]. In case of a "light smear" from DEE, do not use the tool; too hard to fix.  Use PS's Shadows & Highlights tool instead.)  4) Proceed with other PS adjustments such as Curves, etc.  5) Still not satisfied?  Go to Levels again and look at your histogram. Is it really "stacked" to one side or the other (a mountain way over at the left or at the right)? You might want to try the rather severe command of Adjustments/Equalize.  This "spreads out" your pixels more evenly across the histogram. Note: this is a scary adjustment that requires misc fixes to tone-down certain aspects of the Equalization adjustment.  No free lunch, right? 6) After experimenting with the above tools, you should be able to get a handle on too-contrasty pictures. There will be a learning curve.

When ever there is a picture taken there is a flicker when i view the picture in my camera it happens only on the bright spots ...ehy is it


It's normal.

The Nikon dSLRs have various LCD display modes, and one of them is called "highlight clipping warning display". Basically, when you set your LCD display to "highlight clipping warning display"(it's the mode right before the "histogram display"), it blinks white/black wherever your picture has blown highlights (i.e. where your picture is overexposed)

A histogram display is very helpful in telling whether you've got the exposure right, but to it isn't adequate by itself. With digital cameras, it's very important not to blow-out the highlights in a picture (they're similar to color positive film in that respect), since once you hit the maximum brightness, the image just saturates, and any highlight detail will be lost. A histogram display does a pretty good job of telling you how the image as a whole is doing, but what if there are just a few critical areas that you're worried about for the highlights? If only a small percentage of the total frame is involved, it won't account for many pixels. That means any peak at the "white" end of the histogram graph would be pretty small, and easy to miss (or just plain invisible). What to do? The folks at Nikon recognized this problem some time ago, and so have provided another special display mode on the D60 (as on most of their dSLRs) that they simply call "highlights," accessible via the Playback settings menu, under "Display Mode." This mode blinks any highlights that are saturated in any of the color channels. It does this by taking the nearly-white areas on the LCD and toggling them between white and black.
