I have a 14 month old Samsung LCD. We were watching TV last night and the picture disappeared. We have sound, but no picture. We checked all the basic trouble shooting from our manual. Any idea what it could be and how much it could potentially cost? Thanks!

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.
Check the cables, connectors and connections.
Take it to a repair shop. https://www.youtube.com/watch?v=TR2iWN6b-LY
hey Adam i have a samsung that has been doing that.it would come on then after a few minutes the picture would go ou but the sound still worked.i found that one of the connectors that plugs into the LCD board had a broken solder joint were it connects to the back lighting .just unplug your lcd connections if its bad you'll know it because it will come out.
With no video and the the colored stripes, it sounds like the LVDS cable needs to be reconnected to the LCD control board or the control board itself is bad. If the unit is only 3-4 months old, it should be covered by warranty
this would be the pre amp. transistor , audio second pre amp volume control chip or audio amplifier , they will need to be tested to determine which one or ones should be replaced
Does anyone know where can I buy a screen for a 27" LCD Insignia TV. Model is NS-27LCD? My screen creaked. I checked out e-bay and have not found a broken TV with a good screen. Does anyone know where I can buy a screen at. Thank you all for you time. JC
Sounds like horizonal output transistor could be over heating. There could be other problems. But I would start there. You can find the part number on the schematic inside the set. If you change it yourself don't forget to use the included insulater. Part should cost between 15 & 20 dollars. You will need make & model # of set at electronic parts store.
Diagrahm inside set will show you location of transistor.
