Proscan tv power light blinks red and won't turn on, it normally is solid red when off and turns blue when on. whats wrong?

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.

My proscan TV was working fine. then the video went and now no audio.. it lights up briefly when u turn on. then screen goes dark.. is this fixable or better to get a new tv..It is only 3 years old

I believe it's fixable! Take a look on your video and audio cables (behind the TV, the red, yellow and white ones). They must have a problem. Already happened to me!
I hope I've helped...
