Re: toshiba 19inch lcd tv green line down screen
A solid line down or across the screen is due to problems in the display itself. Unfortunately, there's no way to repair it because the bad circuitry is integrated into the display. The only cure is display replacement.
Not the solution you want, but that's how it is. (With the huge number of transistors that are part of the display, it's actually amazing there are as few failures as there are.)

One of the circuit board ribbons connected on the vertical control is probably loose there is a few vids on you tube for this repair , failing that some of the driver capacitors need replacement with higher voltage caps same microfarad.
Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish board that call T-CON board to do a replacement.This T-CON board sit in the middle at the bottom of the tv LCD screen panel.This T-CON board control all the picture pixels going throught to the tv LCD screen panel.
My 52 in regza has a vertical line on the right side as well just under 2 years old, out of warranty and to costly to repair, I paid $2500 as well. The TV has been on its stand since the day I bought it and has been moved once.
I have read of others who have this problem as well, just google toshiba regza red line, or vertical line
I Too will never buy Toshiba products and I will tell everyone I can about the **** LCD Toshiba
I hate to be the bearer of bad news but this is actually one of those known and predicted issues with LCD televisions. What these are called are "dead" lines of resolution aka dead pixels aka frozen pixels.
This is one of the flaws of LCD televisions, there is a completely random, unpredictable fail rate of LCD pixels in all panels, the likeliness of failed pixels varies depending on the quality of the panels used in the TV.
There really isn't a resolution to make them go away, if they are simply frozen, usually a light (VERY LIGHT) tapping of the screen at the top and bottom points of the line will refresh the pixels. If they are coming and going more often, it means that the panel is weak or malfunctioning in those areas and you need a new panel in the TV. Unfortunately it's quite an expensive repair, running at least $400 USD, if you are within warranty period (usually only 3 months for dead lines of resolution.. but it varies up to 12 months depending on the manufacturer) I would suggest calling Vizio and inquiring about a replacement TV. They generally won't allow a repair as it costs them less to simply give you a new unit all together.
My apologies for your bad luck!
The individual pixels on LCD displays are controlled by turning them on and off in an X-Y matrix.
This matrix is scanned at a speed fast enough so the eye can't notice the action of the pixels so not all pixels are on simultaneously.
The kind of failure you describe can be caused by the failure of two vertical drivers that are not being turned on and off any more.
In some sets, the driver chips are part of the display itself, meaning that a failure of one (or more) of the ICs may require a replacement of the entire display panel, a very costly repair.
The ICs are small and have very close pin (contact) spacing, are placed in manufacturing by robots and generally, only specially equipped and steady-handed techs can replace these by hand.
There are solutions for stuck "and not dead pixels" Here are a couple idea's to try and please do not rate me bad if don't work!! That would not be nice as i do not get compensated showing your solutions I get them by your "good ratings" Hence do not use "Thanks for Trying" rather helpful or fixya will do now here are the websites: http://www.wikihow.com/Fix-a-Stuck-Pixel-on-an-LCD-Monitor
If you TV can hook up to a computer witch it can through servral means then you can use this information. But However do not rate me Thanks for trying if the darn thing just dont unstick the pixels... Thank You for using Fixya.com

I have a 50" Pioneer PDP-503MXE with the same problem - the fans don't run. It appears to be a problem with the temperature sensor that controls the fan speed. However, the fans can manually be switched to MAX.
To do this, put the display in standby. Press the 'Menu' button and within 3 seconds press the 'Power/Standby' button. The 'Integration Menu' will appear. Select the 'Option' tab on the right. Scroll down (next page) to the 'Fan Control' option. It will most likely be set to 'Auto'. Press 'Set' to change it to 'Max'. Within a few seconds the fans will run.
At Max the fans are a bit noisey but it will cool the unit down.
If your set is 6 months old, I would suggest to have it repair under manufacturers warranty. All the electronics devices have 1 year warranty.
The failure you have with your LCD is the power supply not working properly.
Let me know if you need further assistance.
