Need to adjust some voltage on the Power Board & Y- Main Board.

Remove the Power Supply cable to Y Main board and check the Vs voltage in Power Supply board.
1. Vs voltage is OK, replace the Logic board or Y Main board.
2. Vs voltage is NG, replace the Power Supply board.

You need to repower the cable box. That should fix it.
Good Luck

after a lot of patience ,perseverance and switching around of numerous cables,we were able to rectify the problem.Now all is well.Thanks for your concern and for asking!

HOW LONG AND WIDE ARE THE LINES, IF 3-4 INCHES THICK, COULD BE A BUFFER BOARD, OR COULD BE THE PLASMA SCREEN ITSELF

After I got over my fustration I did a little more reading and discovered that I could use purchase a
HDMI to DVI converter cable. Since DVI, unlike HDMI, is video only I also had to purchase a digital optical (it also carries audio) cable to get sound. It cost me an additional $70 for the two cables but it was worth it. I reasonably happy with the 1080i resolution which is all my SPN4235 is capable of at least until I can afford a new 60" HD Plasma TV.

VERY EASY TO REPLACE, IF YOU HAVE ELECTRICAL EXPERIENCE, WILL NEED A VOLTAGE METER, TO SET THE PANEL VOLTAGES

IF THERE IS SOUND, PROBABLY THE Y-MAIN BOARD, IF IN WARRANTY CALL SAMSUNG

COULD BE A LOOSE CABLE CONNECTION, NEED TO TAKE OFF THE BACK OF THE UNIT TO BE ABLE TO SEE IT, IF YOU ARE NOT QUALIFIED THEN BETTER HAVE SOME EXPERIENCE ON HAND TO ASSIST

YOU SHOULD HAVE REPLACED THE Y-MAIN BOARD AT THE SAME TIME, NOW DON'T TURN IT BACK ON UNTIL YOU REPLACE THE Y-MAIN OR IT COULD TAKE OUT THE NEW Y-MAIN

PUSH THE SOURCE BUTTON AND SEE IF THE INPUT CHANGES
