The ballast board that controls the intensity of the back lights is not working.

loose wire check connections

If it did work before, it should work now. But if you are connecting a new device, make sure you are using the right inputs. Yoou still can get the manual online, but to point out what I mean I send one picture about how to connect (Only one example) where you have to use 3 colours on the cable. When connecting a video recorder (low quality, you only need 1 colour, for the composite entry (Yellow) The link is for the manual: http://downloadcenter.samsung.com/content/UM/200307/20030708161858250_SPN4235_00487A_0514.pdf

if the band is horizontal your tv has bad y-buffer board. Usually there are 2 buffer boards- top and bottom. if the problem is in the top half of the screen replace the top board, otherwise replace bottom board.but better to replace both a the same time.if the tv has a vertical lines from top to bottom it may have bad plasma panel and can be considered as not economical to repair.

Look for any loose contacts in RC jack, cable and connectors. Try changing the input device to some other that works.

Is the buzzing sound coming from the TV or your sound system? If it's your sound system, then you may have a bad cable or a shorted cable. What kind of cables, how are you connected to the TV? Need more details to be able to provide a better analysis of your problem. Chris [email protected]

Yes,Ur main video backlight board is dead,must be replaced.About $400 part and labors.

Most likely the TV has a power supply related problem. The most common problem are the power supply for the screen itself. Most manufactures call it a Backlight Inverter Board. Something you may want to look at for your problem. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:
1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.
3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.
4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.

First take the Batteries out of your remote control to see if the T.V. is still changing channels or not. If it stops changing the channels and volume, try opening the remote with a knife and clean all the pads with rubbing alcohol to prevent sticking buttons. Be careful if using a remote with a roller ball.

A single red line is a bad panel. The only fix is to replace the panel. Would be more cost effective to replace the TV.

Hi friend,,,
welcome to fixya

Commonly for Plasma tv's if the screen went out,,the problem will be the CATHODE RAY TUBE,it is costly to buy.if you want you can buy it,,or it may be the D-board problem will be also,,,
but it is unusual,so check the tube.

if your satisfied with my solution PLEASE RATE IT

thank u...

Sound but no picture....
Should ask yourself, does it PRIME? Meaning, That's where the Plasma panel lights up a little for about 10 seconds after startup. -- If it doesn't prime, then you need either the SMPS, YZUS, possibly both. OR you might need to check the ZSUZ. Driver boards can be culprits too.
And can you even get to the Menu, Volume, etc. but just picture?
Then you need the signal board.
Unfortunately that's pretty common with Plasmas. Can burn out or burn "in" easily.

Different Brand but similar problem. This site is excellent for do it yourselfers. As for Samsung Parts, be thankful if you are a DIY-er that the parts are much cheaper if you install yourself. Separate with installation adds up very quickly. Personally, I decided to go with the Rear Projection Samsung several years ago and haven't had any major problems. Heard then that Samsung was having lots of complications of this nature.

To be honest though sounds like either bad SMPS and/or bad Y-SUS pcb's.

Wish you good luck.

Do not turn this television on! Any electronic that smokes is NOT GOOD! The smoke and accompanying smell is from plastic and solder that is being melted by a short on one of the TVs logic boards. Call a local TV repair man this is not an issue you could fix yourself and will most likely be better off buying a new television. Stay away from off brands like these, spend the few extra bucks on a name brand like Sony, Toshiba, LG, or Samsung and you won't encounter these types of issues.
