Question about Vizio SV Televison & Video

1 Answer

Vizio power supply keeps breaking

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?

Hello,

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.

Vizio tv mod# SV470XVT1A has good picture but no sound. Replaced the sound board but still no sound. tried all the troubleshooting steps to no avail. What could be the reason that there is no sound?


Try the sound settings. You might have wrong format selected. Also make certain the speakers work.
Otherwise it could be a problem on the main board, or the power supply board that provides the power for the sound board.

My vizio VO47 L has a black screen and sound. I do get a light on the vizio logo on the front. I see no illumination coming out of the back of the unit. what is wrong?


Power Supply popped a cap and fried the metal resistor bank. Replace the cap C241 and solderer the resistor bank. Worked for two months then pop out again. This time the resistor bank burnt through. Bought a new power supply DPS-38cp-1a from ShopJimmi.com $56.00 Replace supply which lasted 1 year 1 day and the same thing happen. Same components. Got this TV free but its costing me time and money now.

Vizio SV470XVT1A makes screeching sound


Hello,

This sounds as if it could be a ballast problem, or a switching power supply transformer problem. Both of these can produce this sound. I would suggest that you have a qualified TV technician repair this set due to the dangerous voltages and currents that could be present. In my experience with these TV I would have the technician pay special attention to the power supply board and the backlight/inverter section which includes the ballast used to fire the backlight.

I hope this helps,

Thank you,

Television will not turn on


My 47" Vizio wouldnt turn on this morning.....had a similair problem 3 yrs ago.....this is what i did and fixed the problem myself.....apparently you have to reset TV. Here is what has worked for me. So unplug tv power cord from the tv. Hold the power button and imput button together ( located on side panel ) for approx 45 sec......plug cord back into tv. Press power button on tv and voila !!!!! Tv came back on!!! I have had my Vizio almost 5 yrs. But have to call the unhelpful customer service atleast once a year.... I hope this works for you :)
