It's the hyper mod board. I've replaced many of these.

SOURCE: wavy line or scrambled picture when l turn the tv

If you have a normal picture with lines through it, or if the picture jumps, tears or rolls, you have a Hyper Board that is failing. The last I checked, the Hyper Board is not available from Toshiba and has not been available for a number of years.
I hope this helps,

Try it on different inputs like out from a box, direct cable or a DVD player etc to see if problem is isolated to one input on the set.

Toshiba 57hx81 tv has a bow at bottom of screen and blue in color tried using toush focus & got error then tried to focus manually & couldn't get the bottom lines to focus all the way down


noted in the owners manual, if auto focus returns message "error" , it suggests to use manual convergence setting..failing that, is it resonable to suspect that the STK-392-110 (convergence (2)chips)are beginning to fail, bendt horizonital lines is the effect. you can check all the resistors and pico fuses (power board)near the chips for shorts, chances are they are ok. seeing that there is somewhat of a picture (kinda like 3-d). i would repaired it!.. while your there do the hyperboard repair as well by replacing the 10 caps with 16v@10uf. (causing a wavy vertical distortion effect).
