Hi
I have a old Panasonic TH-42PW5BX/EX, hooked to its Panansonic external receiver/tuner TU-PT600B.

Recently, I have this problem where only the upper half of the screen goes blank. Its intermittent in nature, sometimes it happens on the first power on of the day, sometimes its ok when power on but returns after a while (no fixed time). Its getting worse, as in that its more frequent now.

Could it be the external receiver/tuner TU-PT600B problem? And can it resolved? Or do i need to replace it? If need to be replaced, can anyone recommend a suitable terminal board for this old 5 series? Probably not getting another external receiver/tuner TU-PT600B cos it too darn expensive.

Thanks in advance for the help.
