Question about Vizio SV Televison & Video
I have a 3 year old Vizio TV model SV470XVT1A. When I moved the TV from AZ to TX it only worked for about 45 minutes, where we heard a loud pop, saw a red, blue and green line flash and it turned of. It powered on several more times, only to power back off to eventually not power on at all. We ordered and installed a new power supply. The TV again worked for around 45 minutes before the same pop of death happened. The only turned on for about 30 seconds before powering down this time. Any ideas on what could be causing this?

Your power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
