Hi


Thanks for using FixYa. It seems that you might have a backlight and/or an inverter board issue with this TV set. To start with check the screws on the inverter boards as if they are loose can cause this issue. To access the inverter board you’ll have to pull the back of the unit and check the right side, also check for cold solder joints. It could also be due to the inverter circuits for the backlights. The inverter is the power supply source for the backlights. All this is only recommended if you have some kind of expertise for checking the internal circuitry of the TV as these units have high voltages running even when the set is switched off. The cost to change the inverter board including labor would be around $250, if you get this done by a professional. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

Should I color my hair purple?


The Purple color that you will colored is amazing.

Angel Brazilian Virgin Hair Online Store will supply you high quality hair with best price. The hair extension you can buy in our store in purple color.that color is good.
A Brazilian weave, also referred to as a Brazilian wave, utilizes 100-percent virgin Brazilian hair to create a soft, wavy style. A stylist can apply Brazilian hair in any weave technique you prefer, allowing you the freedom of choice. However, when a stylist states that she offers a Brazilian weave, she may also be referring to a technique known as the Brazilian knot, where the extension is bound to the hair in small sections using an elastic thread. Taking care of a Brazilian weave is similar to any other human hair weave, but there are a few minor considerations when taking care of Brazilian hair and the Brazilian knot in particular.

Vizio TV has purple haze and colored stripes on the sides of the picture.


You possibly have a failing hi-voltage module or fly-back transformer going bad. If it has a fly-back transformer, It's not worth the trouble. Some repair shops will sell you a module. Call a repair shop for help.

Wavy picture with blue and purple color.


Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

What kind of connections are you using?

If component (red, green, blue) double check to make sure they are seated properly. I'm thinking it sounds like the blue one got loose.
