Question about Vizio SV470XVT 47 in. LCD TV

1 Answer

Hello,I have two flat screen HD televisions with black spots.

Hello, I have two flat screen HD televisions. One is a Vizio and the other is a Polaroid. Both now have a black spot in the middle of the TV's. They were fine when ran to a HD cable box. Now we have satellite and a regular digital box. The satellite tech said this was caused from using a non HD box. Can you tell me what may have caused this and if it can be repaired? Also what repair cost am I looking at? Thank you in advance for your help.

SOURCE: Vizio P4 Plasma green blotches

OK Service tech came out last night (7pm) and repalces the main board and updated firmware to the latest. he said the red/green snow is a fairly common problem with the early units (mine was a july 2006 build). Picture is fine now but we will see how long the fix lasts. Main board was definitely the issue, firmware upgrade was prob just because they could.
Keep in mind this unit was OUT of warranty. I find it refreshing that Vizio took responsibility and set up a service ticket for a 16 month old unit. Not that they shouldn't last a lot longer but they could have just said tough luck.

SOURCE: Vizio L32 32 in. HDTV LCD HDMI input not working

I recently had the same problem with my vizeo hdmi port # 1 going bad. Tried everything to fix and called vizeo. There solution for a master reset was turn off tv and unplug from the wall. then hold down the power button for 30 secs and let go. plug the tv back in and hold down the volume down and input select buttons down on side of the tv for 15 secs. release the buttons and turn the tv on after powering down all the components connectd to the tv. If this does not work they told me you need to have it sericed for a bad hdmi input. Hope this info helps anyone out there. It didn't work for me. Its a bummer cause the tv is well taken care of and only 18 months old. Best of luck to all others.

SOURCE: Have a VIZIO HDTV flat screen and there is a spot

If it is a spot of a foreign substance, take a trip to Wal-Mart and look in the electronics section for LCD cleaning wipes, they are about $2. They work wonders for me!

Happy New Year!

Feedback is appreciated!

SOURCE: Problem with the picture on my Vizio flat panel

a better solution is to replace the LVDS cables or just reseat them as the contractor stated it could be a motherboard but about 90% of the time it is actually the LVDS cables ohm load that puts toomuch load on the motherboard. the cheapest solution if out of warranty is buy an lvds cable and simply replace it if the issue still exist after the cable is replaced it will be a motherboard issue but any time you have red green or blue speckles on a vizio TV you should always swap the cable first since quite simply put it is the most common point of failure with that issue.

Sounds like you hit the PIP (picture in picture) button on the remote. Hit it a few more times and it should go away.
