Shadows on plasma TV are often related to the power board that supply plasma screen volatages. When the board is giving wrong power on the vertical refresh you get shadows.

Similar phoenomena are also caused by bad connectors, and in less frequent occasions , because of a defective plasma screen.

If you want to do it yourself get the service manual first.

If you decide to call a repairman, or you need to validate the guarantee, call the number listed on the owner manual.

Sounds possibly like image retention. If you watch the same channels often any recurring text, logos, or graphics, especially white colored, can ghost on the screen.(playing the same videogame for a long period can also have the same effect) Watching other programs or channels will cause the ghosting to disappear.

To prevent image retention you need to activate the TVs anti image retention mode(Called ISM Method). On Zenith and LG (the manufacturer of Zenith T
s) plasma TVs open the TVs menu, select the Option section (picture of a briefcase with a wrench). Select ISM Method and change it to Orbiter, this is reccomended if you watch programs or channels (or play videogames) that have still images for long periods of time. It moves the image a little every couple minutes.

If watching others channels or programs doesn't make the image disappear, change the ISM Method to either Color Wash or White Wash (don't use White Wash frequently, it over excites the plasma gas and can shorten the life of your TV if overused) for a few minutes and then return to Orbiter.

TV turned on, heard loud pop. Now screen is very dark.

It sounds like the actual tube / lamp inside the unit has exploded. You will need to either get it repaired at a local TV repair shop or replace the TV. Unfortunately with that unit it is probably cheaper to just replace it.

Tv wont turn on

Both of you may have a power supply problem. The PS in plasma TVs is more complex than in LCD sets and therefore more likely to fail.

Since Akai is so poor on product support, they may not even have parts since that set was made by Samsung who also doesn't want to hear anything about them (their site doesn't recognize the Akai model number), you may be out of luck.

In researching Akai, I find large number of folks who will not buy any Akai anythings again.
This kind of performance is unusual for a Japanese company.
