Question about Toshiba 20HLV15 TV

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.

I will check what toshiba says about this problem, but in the meantime, make sure your tv is not overheating, make sure all airvents are open, you said you took it apart so I supose you cleaned all the dust and so on.

Il get back to you.

    Its not a common problem and there is noting about it.

    Id suggest you contact toshiba, your dealer or a local professional for a ANALYSIS no repairs yet, just to find out what the problem is and calculate how much the repairs would cost.

Trutech Digital Photo Frame


Image quality using default factory settings is awful. Colors are over-blown, faces are washed-out, and highlights are cropped. People on the internet compained that there is no brightness control -- there is..but its hidden in a menu. Press the Setup button on the remote and move to the "System" settings. I've found these settings produce a fairly correct balance of color, detail, and brightness:

* Brightness=5
* Contrast=1
* Saturation=2

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

Too much yellow does not adjust with normal drop screen adjustments. can i adjust the light beams.on my philips 50"


Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} 1. Turn the green screen control on the Focus Block until retrace lines appear and gradually turn it back
Until the point where you can see the retrace line disappears, just before cutoff.
2. Turn the red screen control on the Focus Block until retrace lines appear and gradually turn it back
Until the point where you can see the retrace line disappears, just before cutoff.
3. Turn the blue screen control on the Focus Block until retrace lines appear and gradually turn it back
until the point where you can see the retrace line disappears, just before cutoff.
4. If the screen still appears too bright after proper G-2 adjustment, you need to adjust the sub-bright adjustment in the service menu
control down until screen cut-off. (Service data Range is usually 21 to 25 in the Service menu, for Sony sets you first go to category "MCP2", & then adjustment item 01( "SBRT")= subright.
For electrical the focus, put on the screen a clear picture of your choice thru an input of the TV set from a DVD, then pause the playback of the DVD Look into each color and rock that color focus control back and forth (turn the control one way then the other way slowing down as the picture goes into the best focus. till the picture looks sharp do each color till they all look in focus. NOTE: it is best to look into each color tube to achieve the best electrical focus. For optical focus please follow the manual lens adjustment in the sets service manual

Flyback transformers usually have 2 adjustable rods - 1 is for focus the other is for screen (G2) voltage. try turning Clockwise the Screen adjust with brightness-contrast at max. Till you see white diagonal lines, then go back until the lines disappear - then tune the brightness to your desired level.

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!
