Great When the TV is first turned on it plays fine , maybe for an 15 minutes so , then the picture starts jumping. Also has purple static lines horizontally.
Your picture tube is about to go.
If it's still under warranty,take it back.
Hope this helps.

Check the horizontal output transistor this could be damage and causing the problem.another thing is pilot light that cause the screen to light up.since this is a projection t.v.it does not garry a tube.

Oh good, two people. I was getting weary of attempting to slightly change my answer for all the other people who didn't use the "has the same problem" feature. Anyway, the problem both of you have is not too far gone yet, but will get worse if you let it. It's the main capacitors. Maybe not all 21, but probably at least half of the 21 main caps are shot. All should be replaced at any rate. Any shop worth it's salt ought to be able to do this for you for under $400 if you can't do this yourself.

Its definately fixable. Can you post a picture of what your refering to when you say horizontal lines and jumping? Also do you have any soldering ability or troubleshooting experience? Let me know
SOURCE: screen gets horizontal lines and jumpy screen.
Your problem is capacitors CP204 and CP205 by the 9 volt regulator on the main board. Cp204 is a 47 microfard @ 50 volt and the other is 100 microfard@ 16 volts

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.
