SOURCE: TV COMES ON NO PICTURE OR SOUND

If screen is gray glowing, the T-CON is bad or it is not getting the 12vdc from the logic board. You may have problem with logic board but do some voltage checking first.
If you are going to DIY and have proper tools and know safety precaution then please read on:

Samsung 55inch plasma. Sound but no picture. Pushed menu button still no picture and menu does not appear.


Does the screen prime when you turn it on? By that I mean if you dim the lights in the room and turn on the set, does the screen slightly light up?

Looks as though the screen inverter has failed although hard to tell - am I right in saying the screen is not lighting up at all?
ONLY DO THIS IF YOUR TV IS OUT OF WARRANTY, otherwise call the seller or manufacturer and arrange a service.
If the screen is black - i.e. does not light up at all - then it is probably an inverter fault. Check this by shining a torch into the screen holding it very close, a faint image should bounce back at you. If that is the case, you need to open the back, find the part number for your inverter - usually a long panel down the left - and search for one on ebay or on a tv parts website.
If the screen lights up but you have no menu or picture then it is likely a T-con fault - this is a small board positioned in the middle of the TV usually near the top. Once again get the part number and find a replacement.
If the screen lights up and there is a menu but no picture then you're looking at a main AV board fault - that's the big one with the video inputs in. Replace this in the same way.

No picture


Sounds like you have a backlight problem. To verify this, turn on the set, dim the lights in the room, and shine a bright flashlight on the screen. If you see a faint picture you have a backlight fault. It could be as simple as a bad capacitor in the power supply, or a faulty inverter board, or in rare cases a bad backlamp.

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
