My Samsung txn3075 just started acting up. The picture is very blurry. Also the component jacks in the back no longer work, the movers did that.. How do I fix?

Hi' thanks for question. please see this video

It could be that the picture tube maybe be starting to go bad and needs to be replaced. Or the TV might look blurry depending on the input to the TV and also the connection and how the TV is hooked up as well. The focus controls are not working and need to be either readjusted or replaced.

Without the specific LifeStyle model # it's not easy to say for sure, but it sounds like you might have a composite cable plugged into a component video output of the Bose. Assuming it does not have HDMI output, it might have white/red/yellow (RCA-type jacks, aka "phono") and that yellow jack is a composite video output. It would plug into the same color jack on the TV. There are also RGB (Red/Green/Blue) component outputs on many devices and similar inputs on the TV, so you have to match like color out to same color in and make sure the TV is set to composite video input, not HDMI nor component.

Also could just be a bad cable. It's always the cheap things that we overlook, so with the same output/input setup, assuming you match type, try a different cable. The actual color of the end on the cable does not matter, but don't plug a yellow-colored output jack to a red, white, blue or green input jack on the TV - that won't work.

Try reformatting the card or use another new or re-formatted card. That might help.

1. • 1 Examine the back of the your cable box and the back of your Samsung HDTV. Note which cable jacks are of an identical size and color. Those are the ones that can be used to connect the two devices. Samsung HDTVs cluster all the jacks in a single panel near the power cord.
     
   • 2 Look at the square rectangular boxes labeled "HDMI In." These are for high-definition multimedia interface cables--combination A/V cables that provide the highest possible image and sound clarity. Look at the back of your cable box for an identical jack labeled "HDMI Out." If you see one, connect the two jacks using an HDMI cable. If you don't, you need to use another set of cables to hook up your cable box.

   • 3 Check for a series of three round jacks labeled "Component In" and color coded in red, green and blue. These are component video jacks, which provide a good HD picture, but not as good as HDMI. If your cable box has an identical set of "Out" jacks, use them to connect the two components.
     
   • 4 Look for a pair of red and white jacks (possibly connected to a yellow one). These are audio RCA jacks. If you're using component video cables to hook up your cable box, you will need to hook these two up as well: Component video cables don't provide sound. Any cable box that uses component video cables should also have "Out" jacks for RCA audio cables.
     
   • 5 Find the raised circular jack with a pinhole in the center of a milky white plastic interior. This is the coaxial jack. Samsung HDTVs label them "Ant In." Every cable box should have a corresponding jack labeled "Out" or "Ant Out." If none of the other cable jacks on the cable box match, use a length of coaxial cable to connect the TV to the cable box through these two jacks. You can also use this connection to hook the TV directly to the wall cable.
     
   • 6 Turn on your TV and cable box, and set the TV to the input jack connected to the cable box. You can do this by pushing the Menu button on the remote, scrolling down to the "Input" option and pushing "Enter." That will let you cycle through the various input options, labeled by cable type (HDMI, component video). Press "Enter" again when you reach the right component, then exit the menu. You should now be able to watch TV as normal.

My Toshibla is a 52LX177 LCD and it's doing the same thing on the right side. This TV is only 2 yrs old. Anyone have a solution?

I have just started having this same problem, which was in brilliant timing for my best friend's wedding, cheers Samsung!!

Sounds like a heat problem. Could be a bad solder joint or component. Unplug tv and vacuum off all air vents in back. Make sure tv is not being warmed by a heating duct. See if that makes it last longer. If it continues to act up after that then you should take it to a repair shop.

what tv channel surpplier are you using ?.
need to know to have any chance in fixing your problem.

The first thing to check is for loose conections,the problem is related to the high voltage but it can start in the main board with one component loose,when the high voltage is developed it goes to what is call the distributor block,a lot of sets have the focus and screen controls coming out of this block for each picture tube,this block might be bad but before we go to him we need to check everything is solid in the main board.If you are familiar with electronics you can remove the back cover and tap the chassis with a wooden or rubber handle to see if the set reacts,if it does you need to be atentive what area makes it react and flip the board to do some resoldering,If you are not too familiar with tv service you need the assistance from a servicer.Let Us know how it goes or if you need more information.
