So I fixed this tv about a year ago, it had the infamous pop of death and fried some video boards when it went, replaced the boards, and all the bad caps on the power supply, its been working great for about a year now but, it just popped off on me again, no loud pop from a cap going, just went all black, sound is gone also, so no video or sound, the little light at the bottom stayed green though, turned it off and unplugged it, let it sit for a couple min turned it back on and it worked perfect for like 5 min before everything popped off again, I'm afraid I've got a cap going or something so I don't want to keep turning it back on, I'd rather fix the problem before it blows taking other stuff with it.. what should I do, and/or look for? Could it be tempature related? Cuz its like 50 degrees in this stupid house

Re: vizio plasma works for few mins then pops off
If its a cap that's going would it already be bulging? And just hasn't completly gone yet? -

Re: vizio plasma works for few mins then pops off
Is "pop" coming from speakers? Could be AC detect fault.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: vizio plasma works for few mins then pops off
DO you have model #? Pops can be Caps or (what I have experienced) IPMs. Glorious, glorious IPMs.Comment

Hello mates,
I bought this subwoofer a few days ago used and blind and it works erratically, as far as I could see, it has been tampered with, the speaker is not the original one and of 8 Ohm when it should be of 4, and there are some welds like reworked by the boards.
It doesn't have much power (expected more from it) and it distorts if you increase the volume over the middle, maybe it's because of the high impedance of the speaker. The problem is that it has sound when it wants, the led panels all work correctly, you can hear the power relay on power on, but right now... -
Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.
Assuming... -
Set was manufactured in 2012. I'm trying to diagnose where the problem is. I am assuming it is over-currenting after heating up? Display looks fine until it decides to shutdown. If I keep turning it on, it will eventually refuse to power up and requires unplugging to get it to respond again.
I originally thought there would be some easily detected bad electrolytic capacitors, but I don't see the telltale signs. There might be some very minimal bulging on one of the x buffer board. BN96-22092A (LJ92-01852A).
If I unplug the power feed to the X/Y board (LJ92-01854B), the... -
Good Morning TV'ers
Vizio usually starts and works fine for a few minutes then goes blank. Checking voltages when shutdown it reads 5v on the standby pins on the PS and 12v on the 12v pina, backlights are out now. What can I conclude or where to next.
Thanks in advance
