Samsung Plasma TV - Get Sound But No Picture. What Is The Usual Source Of This Problem?

The usual problem is with the PSU of the plasma TV.

  • Sometimes it is the capacitor that has caused no picture.
A capacitor is part of a TV that provides enough electricity to the television for it to work properly. If the capacitor goes wrong it may not receive enough electricity for the picture to appear. It takes more energy for the picture to come through on a TV than it does for sound. This may be why you have sound but no picture.

  • The lighting system may have failed.
A plasma TV uses a small cell technology in which electrically charged "ionized gases" are locked in the fluorescent lamp chambers. When the gas is charged by the capacitor it will show you a picture providing a good display.

Unfortunately, when the TV ages, these ionized gases will start to be affected by their half life. It means the color will start to fade and you can even have an issue with certain things like a TV symbol remaining on the screen even after you change the channel. This is called 'burn on'.

These are the disadvantages of Plasma technology and largely why LCD has become a huge hit with most consumers. LCD does not have the light system failure issues that plasma does.

If it is the half life affecting your TV video you should have noticed issues before. This is why the fault may lie with the capacitor. The part can be $350 to replace. This is pretty close to the cost of buying a newer TV depending on the size you have purchased in the past. Consider upgrading to a TV without capacitor or lighting system failure, so that your TV will last longer.

Hi,
Could be a few things but start with the simple one first.  These sets are notorious for failing capacitors on the PSB.  Power Supply board.  Unplug the set and let the voltage drain for about an hour they hold voltage long after they've been unplugged.  Place the set screen down on a bed.  Unscrew the back panel you may need a star hex screwdriver....  The power supply board is located in the center of the opened set.  A bad cap will be popped, raised or bulding at the top (X)- Top view....  They should be completely flat.  If you find you have bad caps.  Remove the PSB by disconnecting the wire harness cables and a few screws.  Take the Board down to a TV/PC repair shop and have new caps soldered on....  This works 90% of the time.....

I haven't turned my plasma tv on for a whole week until now. It has no picture only sound. I am broke right now and can't afford to pay a repairman. This same thing happened to me before so I played with random buttons and the picture came back. I played with random buttons this time and nothing happened. Can you please help.

I bought a 42" plasma fron currys and yep you got it same thing happened to me it turned out that the bloody thing needed over a thousand pounds of repair and guess what it was 13 months old ,and as far as they were concearned it was out of its warrenty not to be out done I did a little digging but it kind of looked like I wasnt getting anywhere customer services what a joke basically said tough luck packing the tv in the boot of the car I drove it to currys where I bought it took it into the shop found the manager and started shouting about how crap the tv was and how crap his service was this seemed to attract a croud don't know why but it got the tv fixed , there is a law which they don't want you to know about a product has to work for a reasonable amount of time and 12 months isn't a reasonable amount of time  so if you suspect its broke don't fix it take it back if you have it fixed you will invalidate your warranty

I suggest that you check the cords again and see if they are loose. The same thing happened with my sony HD television and I found out the cords had not been plugged in completely. Also check the display settings and television settings by using your remote. If these do not work, try getting your television checked by a repairman as maybe he could fix your television set.

The same thing happened to my sony hd tv, all the wires are plugged in correctly but cause the screen is blank I cannot see the display menu. I would also like some advice on this cause I'm going to smash it up with a hammer!
