A histogram is a graphic representation of the distribution of brightness values in an image. The C-5500 has two histograms. One displays a real-time graph on the LCD screen as you compose your images and during the Quick View of images after they are shot. The DIRECT histogram displays potentially over and under-exposed areas in the image with a grid of squares—red for over-exposure and blue for under-exposure. You can set the histogram to OFF to prevent the histogram from appearing.

No image, Just red and blue vertical line on display.

If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.
Take it to a repair shop.

Tv out of foucs

These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

Failure to get a trully blank or black screen

Have never worked on a panasonic projector before I admit, but you get that effect when the 3 LCD panels inside a Sharp (and I assume all brands) LCD are misalligned. To get total black (LCD Projectors find this rather difficult due to the technology) the red , blue and green lcd pixels must be precisely allignend ( they are adjustable by technician and it's a fiddly job) I reckon the green panel is a touch out and it's peeking out between the red and blue squares.

Blue tints w/ tini blue dots

if you see blue pixel type groups of squares or dots you may have a burnt light engine and this is common in many LCD rear projection sets; a blue screen may mean the engine became burnt--LCD rear projection sets of this kind have an optical enginge--with red,green,blue prizims--sometimes they get burned by the lamp---a photo would tell me or most techs what the problem is---the cost of a replacement engine is very expensive--some models with this problem are covered by Sony even if the set is no longer in warrant

Images has a blue color across the center

Wow, 3 in a row. As described on 2 other projector issues this is very similar to those others. I'll repeat the info here.

I assume this is an LCD. I don't remember the s4 being a DLP projector.

This sounds like the LCD panel used for the blue color has gone out. The image is made up of red, green and blue images layered upon the screen. If the blue panel has gone out then there is nothing filtering out the red light in the image.

It looks like yours has just a secone of the panel dying or comming loose from it's connector.

It could be a simple open and reconnect fix. I personally have never opened a projector, so I'm not going to walk you through it as I do not know how hard it would be to tinker with. It should eb a cheap fix for a true repair man though.

Samsung HCM5525W TV red blue outlines on images

The Samsung has bad convergence IC's most likly. This should be repair ONLY by a trained technician as a TV set is not a place to experiment or tinker with because of the extremly high voltage inside. This repair should cost you in the range of 250 to 400 bucks . Good Luck
