SOURCE: Vizio 42 in TV LCD HDTV white line across to of

That white line (usually jagged) is actuallly part of the transmitted picture. However, you are not intended to see it because it is located in what is known as the 5% overscan area. Your TVs today are more than just cable ready... they are a versital, technology filled multimedia display. You can see that line because the screen size or wide mode you are using is intended for 1080p/24 signals. You have 0% overscan with this screen size setting. This allows you to see ALL of the picture, including portions of the picture the broadcaster did not intend for you to see. You can change your screen size using the Wide feature in the Setup menu. See pg.62 of your user manual for details and descriptions of the various wide modes.

SOURCE: tv wont turn on green led on but no life in the

Answer Television is probably malfunctioning due to electrostatic discharge. Try resetting the television by unplugging it from the power outlet for 10 seconds.

  1. Make sure that the power cable on the display and the VGA cable with trailing audio cables are connected correctly (use the originally supplied VGA cable.) between 'MONITOR' of the TV and 'VGA1' of the display.
  2. Make sure that the display is switched on.

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...

Our Proscan 42 inch LED TV (only one month old) just started going fuzzy. There are green horizontal lines going across the entire screen. If I reset the TV (turn off and unplug) for a minute or so, then...


Possible fault in the convergence circuit, failure of the IC. I advice that you must not tamper on the TV but ask for the warranty replacement without even opening the set. You are entitled to this service and must not throw it off. So call up the dealership and register your complaint .
