Answer
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.

This TV needs a service adjustment done. Looks like a vertical or horizontal IC is failing. I'd go ahead, and shut off until services adjustment is made. Have you unplugged for a few minutes and plugged back in? However, I'd have a service tech look at it.

There is a chance the video board is not working how it should. When a video board starts to fail it can start with these green lines and it can also give you a completely green or blue screen. In this case you need to take the board to a shop so they can check if it's either the digital or analog video board. The boards are not that expensive. http://www.discount-merchant.com/?Click=48427

In the customer menu select convergence and then with the Mitsubishi remote select advanced, you should see a grid of lines.
If red or blue or green are out of position you have a problem in the convergence circuit.
If so, I have step by step instructions for this kind of repair and it can be a do it yourself job.
