My Samsung SDR-5102 is not showing any pictures on our TV monitor. I have checked the cables and they are fine. The manual we have does not have any trouble shooting. What do I do next?

SOURCE: Sound but, no picture

it could be the main, x or y, or buffer board

Sound and picture are two seperate things unless you use an HDMI cable so lets just deal with the picture first
After you do the connection, you need to tell your laptop to present the picture to the TV.
1- On your keyboard, one of your function keys (F1, F2 etc.) will have a short cut for this as a secondary functionality. Check for the function key that has an icon on it that looks like a screen (usually it is f4 or f7). Then hit the key that activates  your secondary functions and the key you just identified. This should activate the VGA output and in most cases will also give you a configruation screen (where you can select it as a secondary display, dual display etc.)
If this short cut doesnt work, you can try this
2- Make sure VGA cable is connected on both ends. Right click your desktop on the computer and select "Properties". On the new dialog, select the last tab "Settings". Click the drop down box under "Display" and you should see the TV as the secon option, select it. Then select the check box that says "Extend my display...", click Apply and OK. This should expand your screen to the TV, you should now be able to drag windows from your laptop's screen to your TV's.
Good luck! (Instructions on option 2 are for XP, if you use Vista let me know and I will look up the terminology for that)

SOURCE: PS3 trouble shooting

i hooked up my ps3 with hdmi cord and it looks good, but the no sound so what might be the problem

SOURCE: Samsung Plasma TV - picture has 6 sections of horizontal lines

All I can say is when you watch T.V. the plasmas run off of plasma gas and when you leave something on for so long it burns in the screen. I have the same T.V. and when watching like the weather channel it leaves lines but they go away. If yours are permanent then you can't do anything, but it may help if you go on your remote and go to "menu" then look for "setup" and scroll down with the arrows on your remote. Look for "screen burn protection" and select "white screen". This will make your whole screen white and it may take out the lines. If you let it sit white it won't hurt it. All one color won't hurt, the only thing that hurts is like bright white lines in front of a dark background. Just give your T.V. a break from time to time ESPECIALLY ON VIDEO GAMES. T.V. shows that are HD usually have their channel icons that move or are very dim and they won't hurt. Just go to what I told you and let it sit about 20 minutes, if that doesn't help, then the T.V. you have i believe comes with a 2-year standard warranty and if it's under warranty take it back if you have the reciept. If no reciept then call 1-800-SAMSUNG.

SOURCE: Samsung SyncMaster 226BW - floating box "Check Signal Cable"

had the same issue, called up customer care of samsung and they suggested me to change the cable to D-15 10 series. I was getting the comp o/p on TV but with the "Check Signal Cable" messg with the old VGA cable where some pin is not grounded used for computer to monitor connectivity.
Abhi..
