Question about Toshiba Televison & Video

1 Answer

I have a Toshiba TV (model 42HP84) that now is flashing multi-colored (mostly red lines). The problem initially was 3 or 4 smaller blue bars flashing in the lower right corner. The problem would go away after a few hours, but I think it has run its course. Can you help?

    I have followed your suggestions, but still have the problem. The screen flashes colored lines (mostly red and green) with a white line in the center of the screen than back to normal.



    I have the TV "stand alone" with no cable box or antenna hooked up.



    All connections seem intact (not loose), all dust has been blown out.

Hi


Thanks for using FixYa. First of all please check your cable box settings. Please also clean the connectors that run from the main board to the screen. It may also be due to loose or bad cable or corrosion. You can also try resetting the picture by following this step-by-step procedure---

Press the Menu button and then use up or down arrow button to select the Video menu. Now press the right arrow button and then use up or down arrow button to select Video Reset then press the right arrow button to reset the Video menu options to original values.

Also check for any local interference such as an electrical appliance or power tool and also check the antenna. If required change the direction of the antenna. If still the issue persists, then the main board is required to be replaced. Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks

My Toshiba cinema series HD separates the red & blue color.


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

My tv went multi colored take it as it looks like a 3d television


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

I just connected my new Kworld PC/TV converter. My tv now displays large vertical color lines. I,ve connected the yellow video cable, s-video cable and the red/green/blue cable. I have a new Toshiba...


Hi and welcome to FixYa,

Initially, a couple of checks:
  • verify that the P/N switch is set to the color system of your country. N (NTSC) for US and P for most of Euroope and Australia;
  • depending on how "old" the TV, the Screen Resolution of the Toshiba may have to be brought down to the lowest possible setting;
  • additionally, the Screen Refresh Rate may likewise need to be lowered say 60 Hz;
  • all of the connections you mentioned are video connections. However, only 1 should be used. You may have to experiment (again depending on the TV) which setting & connection would give you the best picture;
  • offhand, the component connection (if applicable, the red/green/blue cable) would give the best connection followed by S-Video and last would be yellow (composite).

Please postback results of initial checks.

Good luck and thank you for asking FixYa.

Screen hazzy and issue with blue convergence


bad convergence would cause show to look as if it was supposed to be a 3-d movie, if a bulb was going out then people would look purple blue -green,or some other off color, so likely the green bulb is going out from the color of the people you described.

Red, green, and blue rectangular "chads" or squares across top of screen


Hi there, this is easy thing to fix. Its LDV cable. This is the Cable which goes from the main board on to the screen. Un plug the cable from the screen side., then push the cable back. Make sure cable sits in .

This will sort all the problems with the picture,i.e colour problem , picutre squring up and many more things.
