When we turn our TV on we get sound, but our picture is distorted for about 15 min then it's clear. Any sug?


Your TV is about 5 years old.
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.

Your LCD backlighting system is not functioning.Your LCD main board should detect the problem and would give you and error code.This needs an immediate service.See if the Tv is under warranty then you can return it an get a replacement.It usually the inverter that has the problem but also either one(even just one)baclighting bulb goes off it will shut off all the backlighting bulbs,thus a sound with no picture as a result.
