Question about Toshiba 20HLV15 TV

1 Answer

Toshiba 20hlv15 image turns bright colors and will sometimes disappear.

Hi i have a Toshiba 20hlv15 when i turn set on sometimes its fine but after being on for a while the screen colors start to act weird turning bright shades of green or other colors and sometimes the image disappears completely turning lcd off and on sometimes solves this problem and image will return to normal. can anybody tell me why image colors become distorted and how to fix problem? I too am having this issue. The TV works fine or 20 mintes or so, then colors almost go negative looking and continue to get worse. I turn the TV off and let it cool fo awhile and poof its back o normal. I have disassembled the unit and I can't find any obivious issues. I have checked all of the solders with an eye glass and there fine. If more than one person is having this problem, someone must have solution. I don't want to take this unit to a pro until I know what am looking at cost wise. I have no warranty.

    I have been running the TV since I put it back together and it has been fine so far. I was hoping that it was just a loose harness when taking the unit apart. Although, I did not note a loose harness. The dvd player went wacky by just having the harness slightly off. I will run the unit some more and post my findings. I have to say I'm surprised that this is not a more common problem considering there are numerous people with this particular unit with the same issue. Also, just a note the unit was very clean inside, no dust issues, no blocked cooling ducts.

The best contrast and brightness settings for a toshiba crt floor model tv,model 50A61


Televisions are unlike other consumer electronics products. Their setup and settings have a tremendous effect on how well they perform. The best TV on the market incorrectly setup will almost always look worse than a mediocre TV setup well.
Ideally, you'll get a setup disc to ensure the correct settings, but regardless, it's important to know what each setting actually does.
To get the ultimate performance out of your TV, a full calibration by an ISF Certified technician is your best option. Even if you go that route, it's good to know what the calibrator is adjusting. So here's a quick look at the basic settings every TV has, and what they do.
Please keep in mind, this is only a general guide in what each setting does, and rough idea how to set it. Correctly setting up a television is a completely different article.
Where to start
Nearly all modern TVs have picture modes. These are labeled things like Standard, Cinema, Vivid, and so on. Cinema or Movie is often the most accurate setting, with all the controls set to offer an image close to what a director intended them to look like. Most people aren't used to an accurate image like this, and to them the TV may appear reddish, soft, and possibly dim. Technically, it isn't. Other picture modes like Vivid or Dynamic are programmed to "pop" on a store sales floor with an overenhanced, blue image. Because most people don't change any of their TV's settings, this has resulted in most people thinking a TV should look blue.
The choice is yours, of course, but we here prefer an accurate image and suggest you at least try it for a few days. Once you get used to it, you'll never go back. Check out What's the best picture mode? for more info.
Regardless, all TVs need tweaking to look their best. Here's what the main controls do.
Backlight
Only LCDs have this control (though not all of them). This is a direct control of how bright the image is. Setting this lower will reduce eyestrain, and save a little on electricity. Before you adjust Contrast to make the image brighter, try here first. Check out LED LCD backlights explained for more on this.
Some plasmas have a control that drives the pixels harder, which in some ways acts similar to a backlight control. Samsung's name for this on their plasmas is Cell Light.
Contrast
Sometimes labeled "Picture." This control makes the image brighter...up to a point. Every television has a maximum light output. Once you reach this point, increasing the Contrast control further actually degrades the image. Correctly set, you would see a fluffy cloud in a bright sky. Set too high, you'd see a blotch of white instead. As mentioned above, try setting the overall light output of an LCD with the Backlight control first (if available). Then adjust the Contrast.
Brightness
This controls how dark the dark areas of the image are, again, to a point. Every TV has a minimum light output. Once you reach this point, decreasing the Brightness control starts removing "shadow detail." Correctly set, you'd see all the detail in a black leather jacket at night. Set too low, and it would be a black area on a black area, probably with a head sticking out of it. For more information on how the contrast, brightness and backlight settings interact, check out my article on contrast ratio.
Color
Can be thought of as color saturation. Setting this too high will make everything look cartoony. Setting it too low will make for an expensive black-and-white HDTV.
Tint
Rarely will you need to adjust tint, a vestigial control left over from the CRT "tube" TV days. It gives a green or magenta shade to the image.

Toshiba 36A41 pops when I change the channel and I can not adjust color, brightness, etc,and remote does not turn off tv.


The symptoms you describe is the main processor controller is about to fail, when that happens the tv will eventually become unuseable. if the set is more than 5 to 10 years old you will be further ahead to replace the set.

I have a tube tv. the picture as lines and is blur that goes in and out.


If the lines are colored DIAGONAL lines, they are referred to as "retrace lines," which indicates either that the picture tube bias is set too high, or the brightness level is set too high.. If the blur occurs when the image is particularly bright or a particular color is bright, it is referred to as "blooming." This is caused by either a weak high voltage circuit or because the picture tube bias is set too high.

Is the picture set very bright? Try reducing the brightness control to a level where the retrace lines disappear, and reducing the contrast control below the level where the blooming occurs.

If the television is more than ten years old or has many hours of use, the picture tube may simply be deteriorating normally. By nature, they have a limited life span. Before you decide to throw the set out, if you are technically-inclined, try adjusting the bias and screen drive controls for the television as recommended by the set manufacturer (you didn't specify what make or model the set is), and you may get a few months or years of additional life out of the set.

I have a Toshiba 20hlv15 tv that I got from a friend. When I put any dvd in, even a brand new one, it says "reading" and then always says "no disc" . Is there a setting that needs to be adjusted to make it...


the problem is that the laser reader in the dvd player is too dirty to read the disc. you need to purchase a laser disc cleaner they range from $ 5. and run it in the dVd several times until the lazer is clean enough to read the disc

best of luck

Well i really want to know what level the coular and brightness lvel has to be on a toshiba t.v


You can set these controls to your liking, though a lower brightness setting might increase the life of the screen. First, set the brightness and contrast to a level that is pleasing to the eyes, then adjust the color to look realistic - enough color without being disturbing. If faces area look greenish or purplish, then also adjust the tint (sometimes called Hue) until you get accurate flesh tone. Flesh tone is the best thing to adjust for; when you get good flesh tone, the rest of the picture will look great. ALWAYS make adjustments during a live news broadcast, which tends to have the most accurate balance of brightness, contrast, color level and hue. Note that commercials are all recorded in different studios with different settings, and will usually not look right - it's best to just live with this than to constantly readjust the TV. There are also DVD's available which walk you through proper TV adjustment.

Color "burn" in corner


well i think this is caused by a magnetic field created by your speaker. is the speaker the same location for that color burn (lower left corner)? the only way to get rid of that is to remove your speaker or changed it. for all i know speakers used in tv's are magnetically shielded to prevent distortion in the CRT, because their location is usually near the crt. good luck!
