Have horizontal lines 1/4 inch apart over whole screen. How to fix?
SOURCE: Describe your Mitsubishi WS-65313 65 in.... Problem:
look for the CONVERGENCE settings either behind a small panel on the front or through the menu with the remote control
SOURCE: verticle black lines on mitsubishi dlp tv screen
Press the Menu Key on your remote. If your menu shows clearly on the screen, then there is a problem with your source.

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.
The power supply will need to be replaced.

It's either mirror hinge fatigue or dust on the inside.
Mirror hinge fatigue can be fixed by putting a solid color picture (white or gray works best from what I understand) on the display and letting it sit for 20 minutes.
If it's dust, someone is going to have to go in there and clean it out.
Also could be a defective micromirror device.
Try the first suggestion and if it doesn't work, you're going to need a technician to take a look at it.
