I have a Samsung HD TV and it's been working well for about 3 years and now all of a sudden the tv screen won't work. Well i mean it works but all I can see is a black screen with some broken blue lines. At first i thought it was my cable that was the problem but when I tried to play my DVD, the screen was still blank with broken lines running across.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.
I have a UA40EH5000M samsung led tv. Suddenly the screen went blank. only sound is there, no display. Which part may have the problem..please suggest..
Most of the times smashed screen means the end of plasma tv. Although if your tv model is older than 3 years, you could search for same model broken tv's with working screens since power supplies usually last for a few years in modern flat panels. Though you will need a qualified serviceman to do the assembly from two faulty units into a working one.
Beware: Although the process should be safe, it technically voids your warranty.
Enter the service menu: 1 - turn of tv with remote 2 - press and release in the following order on the remote: Info, Menu, Mute. Make sure remote is pointing at the tv 3 - turn on the tv from the remote 4 - you will see the service menu. using the down arrow on the remote select the Reset option. Using the right arrow button at this point will do a hard reset. 5 - Wait a few seconds, turn TV on 6 - you will have to rescan analogue and digital channel but it should be working now.
