VIZIO VP504 Plasma TV Won't turn on

Tykster · 05-03-2009, 11:50 PM

Anyone experienced a problem with this model not turning on? Problem first started yesterday, son turned it off, I came in a few minutes later and it wouldn't come on. Vizio sign is lit up in Orange, so it has power, but remote and manual power button does nothing. I unplugged it for a few minutes and was able to turn it on. However, every time it is turned off it will not turn on again, unless I unplug it again.

This last time it wouldn't come back on again at all.

Any help or suggestions would be greatly appreciated.

Thanks

Welcome to the forum!

It sounds like it is a power supply issue. How old is your display? Is it still under warranty? If so I would call Vizio for warranty coverage ASAP. If not then you may have to consider what the cost might be to repair it versus buying a new display. If you are handy and can get a Service Manual for your display you may be able to troubleshoot the problem and replace the components cheaper than having a tech do the work as a possibility.

Good luck & hope this helps!

Since he seems to have bailed... I am having a similar problem. My Vizio works perfect once powered up and never turns itself off. When I want the TV to turn off it does so but the problem comes when I try to turn it on. It is getting power (VIZIO is amber), and I tried checking all connections. It won't make any sounds or do anything when I push the power button. If I unplug it for awhile and plug it back in it works most of the time. But less and less and makes several clicking sounds.
I didn't hear any capacitors pop, and did a quick look inside with a flash light through the vent holes but didn't see any blown. Any ideas of what it is?
Thanks, Mike

Try leaving it unplugged overnight to see if that helps! Otherwise it could be the power supply as a likely guess.

Have already tried that. Worked the first night but not last night. Any tricks to removing the back panel of the tv? Is it best to lay it on its face or upright on the stand? Any help to getting the back off would be great!

Hey I know this threads a year old, but I've got the exact same TV doing the EXACT same thing. Only difference was the child that turned mine of was a little girl. haha... Did you ever find the solution?

Since it appears that this may be a common problem with this model, I would call Vizio. How old is your set?

We have had this 50" vizio for only 3 years. It has worked perfect until last night. The wii is hooked up along with the direct tv box and the home theatre....we have not played the wii since the direct tv was installed last month. It would not cut on so we slid the tv over to look at the back of it and the tv went off and will no longer cut on. No power at all now, no lights no sound nothing....we took the tv off the mantel and sat on the floor on the other side of the room and plugged it in, nothing. No power at all??? Any ideas

Sounds like a bad connection that came loose when you moved it. If it was an older tube set, I'd suggest a bad solder joint, but I don't know how many soldered connections there are in the flat panels.

Probably doesn't make any difference in this case, but I would suggest turning the TV off before you move it, even just sliding it over.

I got mine January 12th of 09. It was a refurbished model from tiger direct, but I still feel like it should be working longer than just 2yrs. >:[ I'm considering taking off the back and looking at it. Like in this video I found. (Search youtube for "How to replace Control Board on VIZIO P42HDTV10A Ver1"). I was trying to find a video for my specific model, but this was the closest I could find. I am getting at least the orange "I have power" visio logo.

Had a similiar problem tonight, reached around TV and it shut off, sound but no picture. after checking all connections, and getting frustrated I unplugged everything from the back of it and set it on the floor...from there I plugged it back in and the tv worked, so I thought maybe it just overheated somehow, so I plugged everything back in, and sure enough it wouldn't power on...so then I just started unplugging HDMI cables from the back one at a time, I only was using two HDMI ports until today (should have known something would go wrong) but after plugging in three, it failed, don't really know if that has any real significance, anyway the problem with my TV is the first HDMI port is bad...plugged into port 4 and it works flawless now...hope this helps, after reading websites I figured not to even call Vizio and just use common sense troubleshooting. The port must be shorting the tv out somehow, not an electrician but kinda handy

Tonight was watching our Vizio TV and it just cut off out of the blue. Tried to turn it back on and nothing. Did a panicked search on Google and found this site. After reading Wesy58's post above, I tried unplugging HDMI cables. We only have two...one for DirecTV and one for Xbox for NetFlix. By process of elimination, seemed my Xbox HDMI cable was bad. Unplugged it, and Vizio would come on. Plugged it back in and as soon as I powered up the Xbox, TV would blank like it did originally. Tried all 5 HDMI ports, with similar results. Ironically, in the end I switched the cables on the Xbox and DTV, and the cord worked with the DTV....go figure (Probably a new HDMI cord in my near future though).

So, if your Vizio TV won't come on, and your still getting Orange power light on the Vizio logo, try your inputs first...this may solve your problem.

Mine did the same thing; just wouldn't power-on one morning. Unplugging alone didn't help.

Vizio support sent me this procedure and it worked. Surprised me for sure!

1- Power off TV
2- Unplug TV from outlet
3- Press and hold in the power button on the TV for 45 seconds (while it is unplugged from the wall)
4- Release the power button
5- Plug in the TV
6- Power the TV back on
