It distorts at tedge of picture anoying

The lenses from the optic engine of this tv are made out of plastic - in time, due to the heat generated by the lamp, they warp, producing distortions in the image. This is a very expensive repair, over $500 for a complete new optical engine, way too much in my opinion for such an old machine. 
Keep using it as is while you save money for a new one then junk it.

Distorted sound

Poor signal or poor connection to the cable probably. Could also be a speaker issue or the audio board on the tv is failing.

Most likely just poor signal or poor connection on the cable.

Bottom left corner of my toshiba 65h83 is blurred with color distortion mainly magenta and green. Distortion Is a half moon shape with the open end facing the edge of the set. Total distortion takes up...

Have you tried the "Magic Focus" Button/Option in the Menu Setup Screen? If you have and it still is there, You Have a Burned out Color Tube. It is Cheaper to Throw it away and Buy a New one.
Good Luck..

Picture distortion

This is a convergence problem which will require soldering of convergence amps. Occasionally, you can get away with just resoldering the pins of the convergence i.c.s, and other times you must not only change the chips, but also replace burnt resistors in that circuit. In most cases you can get a reputable shop to do this repair for 200-300. Good luck, Russmann.

Toshiba 42in 42H81: Tv needs to warm up?

You have a common problem with this set. The cuicit known as the hypermodule is failing or more specific 11 micro capacitors on this board is failing. it would be best to replace that board but,,,, that board is hard to find. we at the shop or most shops can repair that board. average cost at my shop run you 220. I cannot recoment this repair for a novice. The soldering requires a magnifer twezzers and experience, I have damaged a couple hypermodules before i finally was able to fix one, very delicate and like i said unavailble. Like i said this is fixable. you can contiune to watch but the "warm up time" will get longer
