Toshiba TV - picture incorrect size

I have a Toshiba 28z33b analog tv. The picture appears to be cut off at the sides i.e sometimes text is only partly visible - this is on all spects. The menu doesn't offer a suitable adjustment - I wonder if there is a simple control inside the casing?

    Still wonder if I can deal with the problem myself so any info on this is appreciated

  • ronhud Mar 07, 2008

    As mentioned in the question the display is cut off at all aspects - i.e all available ratios, wide, cinema,4:3 etc. If I can find out the component description and location then I might be able to search for a replacement and fit it.

Hi,

With the indulgence of the others....

Can you post an image of the screen showing the "cut off at the sides". The image has got to be 150kb size or less otherwise the system will reject.

Offhand, if the unit was operating fine before, then I can only suspect a component failure. If the unit is a couple of years, then it is possible that the main capacitor (at the power supply) or some other component(s) would require replacement. Should this be the case, then what you're seeing as "cut off at the sides" could be low B+.

Can you also please post back the model number of the Toshiba CRT TV?

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

There should be adjustments for the picture aspect ratio.

Your widescreen television supports Subtitle Zoom, Conventional 4:3, Auto Wide, Cinema, Wide, Super Live. This means for a normal 4:3 tv picture, the tv can chop off abit from the top and the bottom and the sides stretching the picture to 'fill' the widescreen ratio of the TV depending on what 'mode' it is in.

There is a button on your remote which will toggle through these settings.

If this still does not work then - as you mentioned there is likely a POT inside the set to which may be tweaked. However I cannot offer more information on this.

    I have the Service PDF and Schematics.



    In the service book it explains how to put the TV in to Service mode and then into design mode to correct your problem (Done via the remote control)



    How can I get it too you?


  • dan muggeridge Mar 07, 2008

    I'm pretty sure the Service PDF file will ensure that you can solve your problem,



    I'll have a go at explaining.



    If you mess this up you could make things worse...Most TV engineers would probably do this with their eyes shut...



    turn on the TV.

    press the mute button on the remote and hold it down and then Menu button on the front of the TV.

    Use the tv (not remote) Channel UP/Down to select WID. This is picture width.

    Use the tv Volume UP/Down to modify with width...



    Regards

Black square in middle of picture


your captioning or "text" is on. usually inside the tv menu. if not its your cable or dish box has captioning on. black box usually means its in text mode instead of CC thus the black box rather than text

Picture size/aspect ratio in HDTV and upconverting DVD


In the digital world, you can't have a 4:3 aspect ratio DVD title (720x480) on a 720p (1280 x 720) / 1080p (1920x1080) display without some kind of centering or stretching to some extent. (square vs rectangle) Now, on a 16:9 aspect ratio title (wide screen format) you should have any scaling issues regardless of the pixel resolution. Despite what the sales person told you, trans-coding ("upconverting") lower resolution titles to a higher resolution does not increase the quality of the image. Any attempt to do so would be only to try to reduce block noise and any kind pixelation at higher resolutions. (blurring square pixel blocks)

In the analog world, the quality of the image is based on the encoder and signal depth. If your TV excepts HD analog, you might be able to have your cake and eat it too. That would force your display to convert an analog signal into a digital resolution, letting the TV hardware do all the trans-coding. Manufactures are completely phasing out analog signal receiving, but might have the RGB RCA connectors for backwards compatibility. Eventually, it will not be supported and you will be forced to buy higher resolution content.

Picture on Telefunken 72 cm TV expands beyond screen size


Your screen somehow got switched to theatre/cinema mode. There is a setting on the remote that attributes to aspect ratio. Sometimes it is called "ASPECT". Look for it, and press it until your original screen aspect shows.
