Projection TV no picture flashing horiz arcs across top of screen sound okay


You will need convergence work to this unit. Not cheap.(Not recommended for DIY unless already experienced in this type work). Might contact a local servicer experienced with Toshiba & see if they can give you a quote over the phone. Be sure you are sitting.
This is probably a good time to consider entering the 21st century & look at LCD or LED flat screens.

Mitsubishi TV had horizontal lines across the screen and rolls up


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.

JVC TV 27" Black line on top of screen


This is for the original problem.. Not the second post.

It's a problem in the horizontal deflection circuit. The parts will be available, but you will be in for some daignostic repairs also to find out why it failing or if it has failed on it's own.
There should be a few caps near the IC (an LA7840) that could also be causing the problem. Click the link, it will make it easier to locate the part inside.

This is the kind of repair best left to a TV tech, but get it done now and it won't cost anywhere near as much as it will later.
