Question about Vizio VO370M LCD TV

1 Answer

When I turn on the power, the orange turns white, but no sound and no video

So, this happened out of no where. I was watching my tv one night, no problem. The next day I turn it on but there was no audio no video. The orange light turns white, but nothing. I called tech support, they said to unplug it, try using another outlet, but nothing. Unfortunately, my extended warraty expired a few months ago.. they are asking for $200 to get it checked (might as well buy a new one). I am not a big TV user so it's not like i turn it off and on a lot. Anyone have this problem? My mom told me to change the bulb, but not sure if that would work (especially since theres also no audio). Any help is appreciated. Thanks!

Hello dear , this problem is due to a high voltage fault from the electricity . I have read your message , before you go with your TV to the tech support just loose the TV from behind and check if all cables inside the main board are connected in there positions , second step try to loose the main board and clean it well with alcohol liquid then wait till it dries well .after that , reconnect all cables in there positions and try to turn it on , if it gives you the same fault , that means you should replace a new main board

SOURCE: Power is there, but TV won't turn on

stored voltages are high no touching these circuts becuase they hold charges and alot of screws.
fualty capacitors you say after a while it stays on theres a full charge in the unit theres some type of discharging effect on the set after its off for a while. voltage goes to low or unstable after it is off for a while. your better off getting the service docs for this set if you want to diy..other wise get a tv tech to check it for you. hope this helps

Hello Merobert the problem that your tv set is having is coming from the Y sustain board, it can be the IPM fail, the FET fail or the fuse in that circuit could fail as well which can also cause this problem,what i would suggest is to search this website for the service manual for your tv set the reason being is so you can pinpoint which board it is when you open up your tv set you can replace this board yourself just be very careful and save some money at the same time click on the link below and you will find the Y sustain board for your tv set change it out and your tv set should be up and running and no time thank you hope this helps.

SOURCE: Hello, I have a Vizio 47 in LCD. While watching

Sounds like a failed or at least failing power supply / power board inside the TV. Unfortunately this is a very difficult repair, and unless you are an electrician I would not recommend attempting it. You will want to contact a local TV repair person in your area if you are sure this is out of warranty, more on that in a bit here. This is actually the most common problem with this type of TV, I see it every day, it just happens - sometimes with new TVs and sometimes it takes many years for it to happen.

If you think it may still be under warranty please contact the manufacturer to file an RMA. If you happened to purchase the TV with a major credit card (not a debit card) there is a good chance it may still be under the free extended warranty most credit cards place on electronics. Please contact your credit card company to inquire if they do this, and they will be able to file the claim and get you a refund for the TV.

If you want to attempt the repair yourself please let me know and I will get you the part number and a place you can purchase it from for what you need.

So sorry that I don't have better news but it is definitely a power issue internally.

Thanks
Tim

reset the tv with the tv off, but plugged in hold down the soarce botton on the tv for 5 seconds it should click on and work. if not then there may be curcuit board issues. i found the same tv on the side of the road as somewone was throwing it out, it was leaning aganst their trash can. i brought it home. plugged it in and it went on and inediatly went to the orange vizio light. i rest it and it's been perfect ever since is my comoute monitor now...good luck i hope that fixes it for you..

Solutions (2) Best Solution That little fella is only turned off by unplugging it. If all those little lights in America could be turned off we could do with one less nuclear power plant. If unplugging it is not an option, my wife's solution is to cover it with a piece of black tape.

remove all screws on the back of the tv, carefully pull off back cover. you will see two circuit boards one on the left (Power) and one on the right (Video) on the Video board there is a small plug on the right side with a yellow, white and red wire going into a small white connector. the red wire is what controls the orange light on the front. now that the plug is pulled turn it over and you should see a small white plastic piece that holds each metal connector on the end of the wires in. pry this piece of plastic up for the red wire and pull at the same time, the wire will come out of the connector. now tape the metal connector with electrical tape and tuck it behind something or tape it to the chassis. plug your connector back in. put the rear cover back on. now your tv will only show the vizio logo in white when you have the power on. If you wish to disable the logo for both orange and white just disconnect the white plug completely.
