My 57hx81 has a slight concave bow in the middle top to bottom


Sounds like a problem in the vertical sweep circuit. Check voltages to your convergence ICs. If they are  not to spec then look for bad fuses and capacitors on the power board. These will throw off the DC voltage to the convergence chips causing the bow effect. I've had a single bad pico fuse ($1) cause this symptom.

Toshiba 57hx81 picture unrecognizable


Common problem on these sets--the board is not available--don't buy a used one--only way to get another is to remove the one in the set and send it to PTS Electronics--they repair and rebuild boards--If I have helped you take a minute and give me a vote here as I do this for free.

Toshiba 57HX81 is all wiggly and distorted (youtube video attached)


I don't know about that. Someone probably was rough with it and messed them up. You should have a technician look at it.
