Hi all,


I've got a Hitachi Plasma TV model "55HDS52" and a black square about 2/3 of the screen appeared on the center of the screen and it happens sometimes. If I turn the power off then turn it back on again, the black square disappear or when I watch TV I'll change the channel, it also disappear.


Anybody know what's wrong with it ?

Forgot to mention, the black square appeared in the center of the screen and the picture and sound still working fine.
