I have a vizio vu37l tv..about 2 years old. Last night on its own it started switching to av1...comp...hdmi...all by itself..it even shut itself off. It also switched this morning....why is it doing this and anything I can do to fix it?

If you send the board to us we may be able to fix it.

What you're looking for is having to replace the small SMD IC that the tracks from the HDMI ports lead to.

Sometimes that is all it takes, other times it needs more and just today I've had a case where we just couldn't do anything as the damage seem to have spread to the large processor.

(it wasn't on a Vizio board, it was on a Sanyo, but the concept is the same)

What input is the cable connected to? (Coax antenna In, component video, composite video)

Look on the remote or the TV itself for a button marked Source or Input. Press this. For some TVs, use the up/down arrows to select the input to which your cable is connected. (TV = coax) On other models, you may need to press the Source button several times to advance between inputs. (I'm assuming you have a remote that works for this feature on the TV; otherwise, use the TV button.)

I hope this helps.

(common modern TV setup: VCR on AV1, DVD player on Component 1, PC to the HDMI/DVI and coax to the antenna in. The source button is needed.)

When the tv is set to av1, it means the tuner is not being used, press the input/source button on the remote or tv itself. it should work fine.

I would contact Vizio and send it in for warranty repair. Click on the link below to view the contact information:

Hello, try to use the 3.5 mm directly to the TV, the reason this might not work is because you are trying to use two different inputs at the same time.

Try another HDMI source and see if it works. It the second source works then its a compatibility issue with the first device. You also want to make sure what ever is connected to the HDMI is set for a minimum of a 480p output as HDMI will usually not compatible with 480i. Please take a few moments to rate my answer...Thanks...

If you still have audio and video from component and RGB which means your sustainer boards (the boards on the two sides that powers up your screen) are working. All you have to do is replace the main board. you can buy parts at Vizparts.com, Vancebaldwin.com or shopjimmy.com. Make sure that you give them the correct model and serial number so they can send you the correct part.

Well, your TV is still under warranty. That's the good part.
The only thing I can recommend without voiding the warranty is leaving the TV unplugged for 30min. That way, the TV can reset itself and hopefully correct the problem.

If that doesn't solve the problem, it's time to use the VIZIO warranty.
Here's contact info if you need it.
