52" Samsung that the top half of screen goes black.

Purchased new 52" Samsung hdtv in 2007 it is getting to when watching it, the top half will go grey then black out, the bottom is still on. It is on HD cable box and screen that was once very clear now looks like red, green and blue glitter dancing in back ground, you have to be close to screen to see this.

The HDTV has a heat-related problem check your fans. Do they remove heat? the vertical chips paint the screen from top to middle and, middle to bottom so; your top to middle vertical chip is overheating as is your video chip; that is why you have "glitter" in the back ground. get rid of the heat or, bye,bye TV.

The back light inveterate board and CCFL lamps should be checked. Check and replace the faulty component. Back light inverter can only be replaced as card basis.

Download software from the Phillips web site. Use a usb flashdrive to transfer the download to the TV. This worked well for us and our picture is better than ever.

If the line is present on all inputs, and effects the TV menu you most likely need a new screen.

No picture, sound ok

I have a similar issue. Sometimes the entire screen goes black and sometimes only one-half - either the top or bottom half goes black. The only solution we have found is to gently tap the TV (usually the front side) and the picture will come back for awhile. It almost seems heat related as it only goes out after the first 10 minutes of use. There must be a fix to this.

Top half of screen goes blank.

Replace Y drive and Y sustain boards or check for loose cable connections on the LEFT side of the panel when viewed from the back - delicate job.
