SOURCE: subtitles disappear below bottom of screen

Check to see, what format the television set that widescreen etc. this may be all that's wrong with your set. If the problem persists the vertical height needs to be adjusted.  Most likely through the service menu, if units under warranty you can call Akai.  For further structures.

You can try the special cleaning napkins for laptops, you can buy them in every electronics shop. Operate very softly avoid pressing on the TV surface. If even that doesn't help, well, it will remain like this, because of phisycally damage.

SOURCE: My vizio e420vl turned itself

There are at least two power supplies in any set with remote capabilities; one is on any time the set is plugged into AC and is supplying that indicator and the receiving circuit of the remote, otherwise it wouldn't turn on under normal conditions. The second power supply produces the needed service voltages used when the set is in use. This second supply is a common failure in many sets and it is generally traceable to poor design and the use of low-quality components of a certain type. Vizio may have a repair or exchange program through their service center. I would guess the cost will be between $50-$150 and you might remove the back panel of the set and look for a smaller board with larger-than-average parts on it and is related to the AC cord coming in. It should be fairly easy to remove and replace as these are often outsourced and just plugged into the rest of the set with dissimilar plugs making it simple to install and reinstall.

SOURCE: tv won't turn no the vizio logo only blinks

Hi,

That problem is 2 causes,its either power supply or system board.
This are some D.I.Y procedure for troubleshooting.

  1. Open the back cover by removing all screws at the back.
  2. Try to look at the power supply board and find the leak/bulge on top capacitors.If you found,replace it with the same type and ratings.
  3. If the power supply doesn't have any leak capacitors.Try to power it ON to perform voltage checking.
  4. Check the output voltage of power supply such as 5vdc,12vdc and 24vdc by using voltmeter.If this 3 supplies having a voltage drop or flickering voltage while on power ON.Check the following parts on the power supply,change value/open resistor,shorted transistor and diode or repeat step # 2.
  5. When the output voltage is stable and all parts looks OK.The problem could be on system board.Unfortunately the system board or main board is not for D.I.Y because the parts inside is very logic and very sensitive.That is replaceable.

Thank you and good luck.

Vizio tv screen went gray


Hi Mike,
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.
