PN51N450A2D horizontal lines
The tv has a great picture. However, the bottom 8-10 inches of the screen has black horizontal lines. Have replaced the ysus and xsus.
Any suggestions ?...

Re: Philips 46PFL7505d/f HDTV
I have attempted to download the firmware update from the Phillips Site, but the tv says it does not support the software.

Philips 46PFL7505d/f HDTV
I have a 46" Phillips LED HDTV.
The Panel would light up, but no picture. I have replaced the video board and now I get a picture. However, it is upside down and reversed. All numbers on replacement board are the same.
Thanks,
Steven

Re: Samsung DP50747 Powers on then off
Update!
I rechecked all my cable connections and found one that was not secure. It is working great now.
Thanks Tom66 you have saved me once again.

Re: Samsung DP50747 Powers on then off
Tom, where did we leave off? I did replace the Main Power board and now I get a green power led that stays on for about 6 seconds then clicks off. The panel still does not light up.
Thanks,
Steven

Adjusting the set_up & set_dn both affect the color/darkness of the picture, but neither help the clarity.
