SOURCE: hd picture too wide

If you are using a cable box you need to look on your cable remote for HD ZOOM or you can try the # sign on the remote. This should change your screen size and get you taken care of.

Look at it on the QVC channel where you have boxes with straight lines. If any of the 3 colors are bowed and 1 inch off, then it needs parts inside. If the colors are straight and only 1/4 inch off, you can adjust it. Using the remote, in the menus find convergence to adjust. Your user manual will explain it. At WWW.Toshiba.com you can download the manual if you do not have it.

On some models there is a picture position setting. One for horizontal and one for vertical. Don't mess with convergence, that probably won't help. Older models use knobs; new ones use the menu. Either way, you are looking for position adjustment.

Older sets, for each there should be size, hold, and position. Same for menus but it may have a picture that looks like one square offset on top of another.

Good luck. and if you need more help, please state the model #

SOURCE: Picture image is unsettled when

LINES or noise from left to right etc. This is a classic problem in a lot of these sets--that this clears up after a while is also typical---the period will gradually get longer and longer for it to become normal.

This set uses a Hyper board for all signal from all inputs---about two dozen tiny surface mounted filter capacitors on that board---they dry out and lose value---flat caps will when hot attempt to regain some of the value they should have.


Board is no longer available from Toshiba, only way to fix is remove one in set and send out for repair to someone like PTS Electronics.

I have seen experts try to replace the tiny caps--usually several are off value or open---cheaper to send board out. Last one I saw cost was about 200 for rebuild, keep in mind same problem will happen again in 5-8 years.


Let me know if you have questions and if this told you something you did not know, rate this solution as very helpful as I do this here for free.

I believe the blue lamp in my 57H81 is going bad.


You need to replace convergence out chips in your Toshiba 57H81 tv by qualified tech because 3-D look picture in rear projection tv shows some thing wrong with convergence output chips.
Your tv model number shows it is rear projection tv that use 3 tubes to make color picture on front screen where as dlp tv use one lamp as back light source to present picture at front screen that is generated in light engine.

Screen was pushed in, takin covering/surround off and fixed screen, replaced covering/surround but colour not right, can see rainbow effect on pitcure. is there a certain way screen must go to transform...


If this tv has a feature called magic focus or perfect focus which is a button inside door that flips down on the front, then it has sensors on the inside of the screen. When it was pushed in, these were probably messed up and will cause a poor picture. It may be difficult to get those realigned. Magic focus will not work right until they are realigned.
