    I disconnected the power cord (power point?) for 1 hour, no change. Still lower third of screen with arcing, rainbow-like, blue lines. Most images and text superimposed in blue above original location.

    leekiller, great call but didn't get it. wasn't aware of that adjustment but unfortunately unable to lower the blue on most of the positions. down a bit but not enough to make a difference. in fact the blue will go down to a point and then start back up, only '4' centered and the lower three never really get close. red adjusts like gold. I'm hoping there's just a failed plug-and-play module that's failing.

It sounds like an internal electronic component is faulty. More likely a burned capacitor and resistor. Try taking off the TV chassis and look for any burned components inside. Replacing those could fix the issue. It seems like the convergence IC needs to be replaced. It would be better if you call a pro TV tech to carefully diagnose the TV and possibly replace those faulty electronics components. If you have a knowledge on basic electronic troubleshooting like soldering and ohm testing, I guess you can give it a go.

This is a convergence problem not a reset problem. go into the video menu and look for manual convergence. you could try auto convergence if your tv has it but i think you will have to go in and manually do it. just line the colours insync with the white bars and this will clean up the colours on your entire screen let me know if this doesnt work but im pretty confidant it will

Toshiba 50h13 image trembling


something is not in tolerance in the deflection circuits if it is an up and down tremble its vertical deflection related and if its shakey from side to side its horizontal deflection. You will most likely need a skilled tech for this type of repair.

57H81Toshiba Blue Line not straight


You have a bad convergence output IC in the blue vertical circuit. On the bottom side of the chassis you will see a " V " printed by the heat sink. You will need to unsolder the heat sink and the 20 pins on the IC to remove it. Replace with STK 392-180 (sanyo) if possible or STK 392-150. Looking from the rear the heat sinks are big aluminum finned rectangles. There are 2 heat sinks one marked H and one Marked V. Even though you have a horizontal line your problem is in the vertical IC. Be sure to use a liberal dose of heat sink compound.

Does not power on


You can get a service manual by going to this link and entering your model number. http://www.servicemanuals.net/
You should check the horizontal output transistor and low voltage regulators first. Unless you have some experience in basic troubleshooting, you should be warned that you can still get shocked even after the television is unplugged.

Blue will not Converge


This is the typical convergence problem. There are two IC's that need to be replaced. They are soldered into the printed circuit board. If you have no soldering skills, and are in the US, you can take the model number and go to http://www.ptscorp.com, as they will rebuild or sell you a refurbished board . There is a phone number listed at the site if you need help getting the pricing. Good Luck
