If you have tried using different input devices, looked for loose contacts
in power outlet, RC Jack, cable and connectors, the TV might need service.

eithor the flyback just craped out or the tube went
try turning up the flyback failing that call a service tech and ask for a quote
quote cose 30-50 bucks
atleast you will know forsurre if it's worth fixing

check the setting of the TV.

if the pic is there when a flashlight is held to the screen the backlight/inverter has failed.

you possibly have a deflection or convergence fault.

Probably what happend to mine. It's all the same problem. It's actually fixable. I repaired mine.

i was watching tv and in the middle of the show the screen went black, but there still was sound. i turned it off thinking it was the cable for that program and when i turned it back on several hours later it still had no picture all connections are good.

It will burn into the screen overtime. The Akai units have a resistor on the address board that feeds the PDP that usually has a crack in the solder on one or both ends of it. There are about 4 address boards that are right below the panel itself and the suspect one is the board right below the line that is appearing. Have someone with solder skills repair it.
