Samsung: PN50C450B1DXZA

Okay; the tv was working bt it had a thin vertical line on the left side. i attempted to find out which board was going bad. Ok, i unplugged them and now no picture. I unplugged the x board and replugged it. that when it clicked a few times and now no picture. If i unplug the x board; it will make sound and it appears that he picture will come in, but it never does. if the x board is plugged up; no sound no attempted picture. wen the x board isnt plugged up; and i power it on; i can still see the thin vertical line. do i need to replace the x board and what can cause the very thin vertical line???

Re: Samsung: PN50C450B1DXZA

It can either be a faulty board or burned chip on panel ribbon cable.

It will not be repairable if it`s a chip/ribbon failure.

A thin vertical line would make me take a closer look at the supporting board. (bottom of tv panel)

A 1.5" black vertical bar would be whole chip failure. (parts tv)

If you keep doing what you are doing it won`t even be a parts tv.

thanks.. it acts like it going to come on when i plug it up. it makes the samsung sound and i can see the screen glow; then it goes out. could the x board be causing it to hv no picture???

Check you seated the control connector for X board correctly.

Re: Samsung: PN50C450B1DXZA

If you had a coloured line, the plasma panel (PDP) was likely bad. It's more than possible it went from slightly bad to completely shorted, taking out the whole picture in the process.
