P-6860 blank screen during start up the screen has a line horizontally through it and has dual images of the loading screen. After loading is complete it is just a blank screen with the line still running across it but the disc drive light is going and you can tell it is starting up but just has no image.

If it works fine when you connect to your tv then you've probably got a loose cable on the screen. You'll have to strip it to check.

Battery is stuffed, replace it. White lines is the early signs or the LCD is damaged and needs to be replaced.

It sounds like the panel is defective

It sounds as though you can see Transmission lines which are sent out with any broadcast at the top of an image, The TV should normally blank these out, i suggest checking your horizontal and vertical settings

This sounds like it might be a defective CCD imager. If so, Canon should fix this for you for free worldwide, and may also include free shipping both ways (free shipping varies with countries). This is regardless of your camera's warranty status. Please check this link for more info.

If the menus and icons look normal, but images are distorted or discolored, you may have an image sensor (CCD) problem. See Canon's service notice regarding this issue here. Canon will repair your camera at no cost regardless of warranty. Contact them at your regional Canon service agency.

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.

Sounds to me more like an LCD display issue

Take and bench test it. Pioneer brand do that when the ribbon cable is cracked. It is the one that get drag in and out during open and close. Open it up and check that. Goodluck.
