Hello everyone I had buyed sony bravia kdl 40EX520 some time before . I am very annnoyed with sony bravia kdl . I think that sony bravia kdl will be a good led for my home as it comes from sony but it is not true . I think it is the worst led and I am very annoyed with this led . it always used to crash for which I have to call its service center . also its voice is very bad . sony store employes said that its voice is cristal clear at the time of buying led but it is not true . its voice is very harsh and unfit for our ears . also its picture quality is not good at all .
