Picture darkens slowly, dissapears, then re-appears only to darken again
The picture keeps fading in and out. The image will get darker and darker, then the blue screen will turn on, although I can still hear the sound, but it is quiet. The image will re-appear again a minute later, and repeat the cycle over and over again. I have tried different inputs on the tv, but nothing seems to work. Do you think the cables themselves are bad, or is the unit toast???? Thanks so much, Shelley

90 percent of the problems with flat panels comes down the power supply board. Without this actually in my shop there is no way to know for sure but I would try that. If you take the back off you will find the main PS board. Get the numbers off of the board and do a search for the replacement. A great resource for this is Allied Electronics. I use them all the time. The price of the board should be pretty inexpensive so no losing much if you try it out. Good luck.
Ensure that a cartridge is not inserted
Hold down the Hint (?) button while turning the unit on. Continue to hold the Hint button down until the LEAPSTER menu appears.When the LEAPSTER menu screen appears, press the A button.Touch each of the crosshairs that appear with the stylus, Restart unit
if no any power indicator the first place to be check is the power supply where in the fuse get blow. if the fuse blown with darkened color that was mean has shortened line, might the amplifier circuit get damaged that cause of popping before it totally down.check for bad amplifier ic and shorted diodes.
ONLY CRT-TV's are prone to magnetic interference so you may want to rethink the cause. Are you sure the acoustimass module is the culprit? Routing all signal cables away from or as non-parallel as possible relatiev to power cables and sources of magnetic fields might help prevent leakage through the cables.
you should really see an electronic technician , your problem is not that bad , just electronic parts getting loose ( must re-apply solder to them ) and this will solve you problem , some calibration have to be done also !!
Can you describe the 'box'? Is it the top half, bottom half, a little of either? What kind of TV do you have?
I suspect you might be noticing the aspect ratio of the various source programs being presented differently on a wide screen than you are used to. DVD programs come in a variety of aspect ratios. Normal TV is 4x3, that is, 4 units wide versus 3 units tall. Wide screens are more like 16x9, so a 4x3 image presented properly on a wide sceen would have black vertical bars on both sides. That is normal.
Some people are offended by the black bars and TV's are unfortunately designed to allow gross modification of the image to fill the space. That is akin to taking a photo of yourself and stretching it to fit an improper frame. That probably wouldn't be very flattering to you and certainly wouldn't be accurate. Which is more important - the picture or the frame?
Almost always, your described problem indicates a blown fuse inside the DVD/VCR combo. Exact location would depend on the model and regional version. What is common to all is that it would be immediately after the power cord as it enters the combo unit.
Some ideas to further guide you if the fuse is glass tube type:
if the break of the fusible wire is clean, then it would be relatively safe to simply replace;
if however, the glass tube is darkened with burnt marks, then there would be some other components defective such as the regulator transistor and/or filter capacitor.
Thanks for giving me the opportunity to help. Sounds like you are inadvertently activating P.I.P (picture in picture) with your remote. Perhaps the P.I.P button is next to the volume control. The black box you mention, is a blank channel. That means the way you have your cable box set up, there is no signal coming in to that p.i.p. tuner. Press the P.I.P. button and see if that's what's happening.
