TV won't stay powered on

I have a year old e500i-b1 that when I push the power button, the light comes on, then after about 1-2 seconds it goes off and I get nothing.

I've tried holding the power button in for 30seconds, a different power cord, disconnecting all devices from the inputs, etc. nothing works.

when it first started happening, if we left it off for a couple of hours or overnight, it would come back on. Now it won't stay on at all.

Also, tried the flashlight test, don't see anything. And I don't get any audio.

Any idea on what could be the issue?

It's over. Vizio offered same type of technician that would charge a service fee just to look at it then another fee to repair. It would cost me almost as much as the tv.

Hey! Had this same problem....and here me out..... turns out my remote control was on the fritz... try taking the batteries out of your remote and turning on the tv manually.... worth a try!

It's the power board.

You must have installed another faulty board...

Bill Carberry not sure if you are the OP of this question. From what you are describing it sounds like a bad power board. Remove the back of your TV and take a look at the individual boards. Post some good images with your question so we can see what you see. Even if you would blindly go ahead and repalce every board in your TV you'd be looking at no more than $200USD. This "charge a service fee just to look at it then another fee to repair. " is the reason for ifixit's existence. Let's all try to help each other out and save our hard earned $$$. It ain't over until the ... (political correctness) lady sings

I am the OP. And I actually just ordered a replacement power board, will let you know how I make out with it.

さんによる

I thought so. Great that you ordered it and let us know how it works out.

I was recently given one of these TV's for the same reason. The guy said if I can fix it, I can have it. Challenge accepted. I'm planning on doing a video on the repair attempts. Any luck on yours?

Same issue, I ordered a new power board. I will received it in 2 days and let you know if it fixes it. The issue is immediately after being plugged in the logo VIZIO underneath the screen lights for 2 seconds and fades out with no feedback or light on the screen. Since it does not power on I assumed the power board was the culprit. Replacing every card in the TV will cost about $100 to $150, the power board was free shipping through ebay on $32. Best of luck

Hi, Is it a year old or just under? Check the date on your purchase receipt. There is a manufacturer's 12 month warranty on your product. If it is within the warranty period check the warranty information that came with the Tv as what you need to do to make a claim for a warranty repair.

1. Inspect ALL Ribbons and connectors. Any tears or bad connections between boards must be replaced FIRST

2. If you have any of these boards, it should be the first board to be replaced

A) T-Con Board - Video Problems (No Video with standby light on, audio but no video, grainy, distorted, or color problems in screen)

B) X or Y Buffer Board (Plasma TVs only) - Standby light is on but no power

C) Backlight Inverter / LED Driver - No Video with standby light on

3. Main Video Board

- Standby light is on but no power

- Either video or audio does not work (if no T-Con in TV. If audio but no video it is T-Con)

4. Power Board - No power AND standby light does NOT turn on. If standby light is on try other boards above

5. Panel - No power, distorted picture, lines, slow motion, half screen, faded in / out. Panel problems are usually not worth replacing the panel.

I have an older vizio with the same problem. When you turn it on the power light comes on but goes out within 2 seconds. I inspected everything and it all looks brand new with one exception. An Elite 120uF 450v capacitor had what looked looked like a burn mark where it was soldered. Would a bad capacitor cause this problem?? Thanks.

Sure... If there is a burn mark it may just be a bad solder joint and resoldering it may fix it.

Hi I replaced my power board and that did not fix it. Then i replaced the main board and that fixed two TVS that was having the same issue. Hope that helps.

I replaced the main board, but that didn't resolve the issue...it was the power board.

Need help! My vizio TV has a pink power light that comes on then fades out. I can press the power button and the power light will show up pink again, and the Vizio emblem will flash 1 time and go off. Any suggestions to the problem? Thank you
