VIZIO M502i-B1: Fuse Is Causing Power Board Problems...
I bought the TV at Best Buy on 12/31/14 for $599. Saw it was on sale for $499 on 01/05/15 and got my $100 refund and applied it toward the 5 year warranty.
Set it up on 01/06/15... The picture was great. My fear of pixelated images was all for naught. I was even able to get rid of that "soap opera" effect through the settings. After a couple of firmware updates the sound was fairly loud. I'm more than half deaf and level 5 is loud for me.
Over time there seems to be some gliches...
The TV wouldn't respond to the remote every so often. It wouldn't even power-off using the power button on the back. Had to unplug the TV for it to function properly again. This happened frequently.
Then, after viewing Netflix the network station would only show in a tiny box at the top left corner ...!?!?!? Had to unplug TV to get it to function properly again... This happened several times.
EXACATLY three month after setting it up, 04/05/15, I manully turned the TV off (as I always do). When I returned home I tried to turn the TV back on. It displayed the Visio "V" logo, faded as if the TV was coming on, flashed the "V" logo and went black. It repeated this every 45 - 60 seconds. I search the internet and found that this has been a problem for Vizion since 2012. Doing the power discharge cycle did nothing for me.
I'm well past my refund period now I can only play Vizio's game of havig them send technicians to "repair/fix" my TV.
Who knows how long the fix will last....?
Professional reviews should be based on the TVs' longivity as well as thier functionality when new
After Vizio sent a technician back in April 2015 the televison has been working 'reasonably' okay. But I never touched the power button on the TV again. Well, two months ago the TV stopped coming on instantly. It took about 30-45 seconds before it would come on, and this is only after holder the power button on the remote for 3+ seconds.
And NOW, two weeks ago the power went off. At first the TV wouldn't turn back on for nothing until I did that power cycling thing. To my surprise it worked. But... I had to reorganize my devices so I turned the TV OFF and UNPLUGGED it. It would NOT turn on again. It would not turn on for nothing, not even by doing the 'power cycle', or waiting for the capacitors to discharge or ANYTHING.
I ended up ordering a new power board (ADTVD3613XA7) from Partstore.com. When I got the board I noticed that there indeed was a fuse on the board. So I swapped the fuse from the new board with the fuse from the old board and plugged the TV in. BAM!! The TV worked. But I was curious. What would happen if I unplugged the TV again? So, I turned the TV off, unplugged it and waited a couple of minutes. I plugged the TV back in and TRIED to turn it on and NOTHING. WTH?? I'm wondering does the fuse blow just by turning the TV off and unplugging it?? I unplugged the TV and took the fuse out to check it, and it looked ok. I did the power cycle to discharge any capacitors and put the fuse back in. By chance I did another power cycle (this is important I found out) and plugged the TV back in. BAMM!! The TV works again!! Again I turned off the TV and unplugged it, re-plugged it and it doesn't work again. ?!?!? I put my OLD fuse back in and tried the power cycle sequence and the TV works with the old fuse!!
Apparently, the fuse is shorting the power board and preventing the 'power cycle' from completely working. I had to follow the exact sequence below for this to work. I tried different sequences and shortcuts but failed:
While TV is unplugged...
Take out fuse, hold power button for 12 seconds
Put fuse in, hold power button for 12 seconds
Do NOT plug TV into outlet until you are ready to leave it there indefinitely.
VIZIO needs to fix this!!!
