Re: horizontal lines

If this model has a "lint screen" or air filter, I would check to make sure the set is getting proper ventilation. Otherwise, you probably have a bad solder connection or capicators going bad, causing your symptoms. Hopefully you won't have to get a replacement Printed circuit board as they are quite expensive.

TV turns on with a green screen with curved horizontal lines.

It seems you may have a serious problem with your video board. That's why you are getting those symptoms. It's better if you replace it asap!

Mitsubishi TV had horizontal lines across the screen and rolls up

ONE: Yes, the speaker mounted close/near to the set can be a cause of mischief; please move it further away and see if that helps clear up the problem. But, you must keep it away for several days before you will know for sure because it takes some time to degauss all the internal parts that may have become corrupted by the magnets in the speaker.

TWO: Yes, any set can be repaired the question is cost and wisdom. Old sets are sometimes not worthy of the repair simply because of the likelyhood that another failure will follow soon after. A big screen always invokes a repair charge of $200 and up. After a few of these you will wish you had put all the money into a new set!

THREE: The lines are most likely a problem in the vertical blanking circuits of the set. These are horizontal retrace lines that are supposed to be blanked out during vertical retrace of the raster. Think of it as a paintbrush that scans across the screen painting thin lines and when you get to the bottom of the screen it goes quickly back to the top, but during that time the horizontal, which is many times faster, has made several sweeps; so it must be blanked out during the retrace. The repair involves finding the guilty parts and replacing them. Usually this repair runs over the $200 somewhat.

FOUR: Prior to calling in a service tech try a hard reset to see if that will recover any of the circuit degradations. Merely unplug the power cord and leave unplugged for 4 hours or more. It may help. Or, it may not help; but worth a try since is won't cost you anything.

If the set is over 5 or 6 years of age it probably is not a condidate for any expensive repair. On the other hand, it is a Toshiba - and they make a fine set.

Hope this helps. Let me know if you have further thoughts.

I would suggest to put a mark where the original position is, just in case you have to go back to the default position.
Good Luck.

We had a blue cone on the screen. We have adjusted the sharpness, contrast, and cross hairs. The cone has almost completely disappeared, but we still have blue shadows. Could this mean a blown color tube?

Any suggestions would be greatly appreciated.

Picture loss!

It sounds like cold solder joints on the vertical IC chip. Not a major deal. The entire board should be looked over for other joints becoming cold.

Your red CRT socket may be loose or have cracked solder if not, try turning down the red gun screen control inside the set just a little. Youre experienceing what is known as retrace lines

Horizontal lines in picture

That's almost always due to RF interference from an electric motor. It doesn't even have to be close to your TV, just operating on the same circuit or near a poorly insulated wire, which acts as an antenna, injecting 60Hz (and harmonic) noise into the power supply.

If it's right next to the TV it will be even more pronouced because the RF interference resonates into the TV circuitry itself, not just the power supply to the TV.

Typically a high current AC motor like a vacuum cleaner, refrigerator, dehumidifier, air conditioner, furnace, etc.

No Blue. Horizontal Lines.

Not to me, but it also depends on if you could do this yourself or not. And the area you are in sometimes is responsible for the cost being high.
