    Thanks for the input, I'm sure that will be the fix if we need to go that far. Of course after I posted this problem, and my husband unplugged the thing for a day and removed the right audio cord from the cable box. We plugged it all back in and it hasn't made the snap, crackle pop sound since.

Since these do employ high voltages, you might be hearing an arc-over due to the accumulation of household airborne contaminents or moisture gathering in a dust buildup.
I suggest you pull the plug for at least a few hours to allow stored voltages to dissipate, remove the back cover of the set and with a clean paintbrush and a vacuum held close to it, remove any visible dust deposits.
Button it up and see if the problem has lessened.

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.

When I first turn the AKAI 60 " TV on the picture


Replace the main power supply as the smoothing capacitors are low value due to ageing.

If you were to log on to the manufacturer's web site, I think you will be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, list of Dealers for spare part supplies as required.

The information is normally free of charge.

I hope this helps.

It sounds like you have failing capacitors in the power supply. It would be best to have a technician to look at it or locate a power supply for the TV and replace it.

Hello drifter,The design of the tv enables the auto search to detect any input signal you have selected. It could be TV (off air, video signals etc) so just switch on whatever inputs to the akai plasma befote you switch the Akai plasma on and let it do the work for you. just relax and watch the tv. recap 1. switch on the input eg video deck, DVD, VCD, or satellite dish. 2. switch on your AKAI PLASMA and 3. wait for the akai to search for your input signals. TRy this simple procedure and if it doesnt work just post back the message. The DON

Check the cables that run from the main board to the switches and the manual buttons on the set, sounds like a cable needs to be reseated, or could be pinched or crimped
