Sony 34" XBR TV Picture does not fit on Screen. How to change setting?

Sony sets have several protective circuits that blank the screen if something happens that might damage the picture tube. One of the more common causes is trouble in the vertical output circuit. Given the age of your TV (the XBR models have been around a while), this might also be a symptom of a picture tube starting to fail. Most of these sets have circuitry (called AKB) that adjusts the color drive signals to the picture tube to keep them balanced. If one of the colors is enough out of range the screen will blank. It might be the tube itself, or failure of some part in that AKB circuit. The set might also have defective parts in the input switching or video processing stages.

Unfortunately, I can't suggest any place you might look if you want to try repairing this on your own. This kind of trouble usually needs to be diagnosed and repaired by a professional TV technician who has the service information to track it down.

Hope this has been helpful. Thanks for using Fixya!

A solution I found for our KV-32XBR200 was to press Setup on top of the set, then select the "Demo" item with TV/Video. The text overlay apparently banished PIP. Verified this twice, as I'm at this page because our remote can only turn PIP on :-).

Sounds like your TV has a PIP (picture in picture) that allows your AVI (audio visual input) to be viewed simultaneously with your cable input. Check the manual for the correct buttons, but the one you're looking for says either PIP or AVI or something along those lines. Hope this helps

sorry your tv is distroyed
you need a new screen
this happen to me
wave of colors that won't go away

Try using your TV remote by pressing View Source. I didn't have Toshiba but my pix did not fit screen either. I used View Source on remote and it changed how the picture filled the screen.

if youre using skybox or freeview make sure the auto format setting is switched off. youl find this in your menue setting

wow. mostly all new set from the last few years have a dual tuners
NTSC and ATSC and that would depend if or which set will get the better signal. Also remember that off air is analog and the sets are now design for digital.

I don't have the XBR, but on my sony, using the cable box remote, I had to go into menu/display/etc. and mark the 1080i, 720p, and 480i settings. you usually get a "if you can see this" comment if your tv accepts the settings. for standard tv i set the screen to normal, and when the upper channels go to HD, they auto go to full screen. Sounds like you are using the component cable, and also make sure you are on the video port of remote, and the the TV input. The above worked for mine. Hope it helps.

posible solution is adjust the screen to low.also check the trimer if it is working.check the resistor in the heater line...weng
