Vizio M420NV Wont turn on

I have had my TV for a little over a year now. I feel asleep watching netflix and when I woke up the screen was flickering and wouldn't stop and the TV would not turn off. I unplugged it and waited but now it wont turn on at all. The Vizio logo still glows orange when its plugged in but nothing else.

I have a suggestion if you have and are using a box of some kind with this set, remove set and box from power for awhile and then power both back, sometimes a box can trigger this type of event, hope it helps and it cannot hurt to try.

SOURCE: Vizio TV wont turn on after three weeks no use

My vizio recently did the same exact thing. Vizio sent an HDTV tech out to fix it and it was the power board. He put a new board in (took 15 min) and the tv works like new.

Philips 47pfl7422d 37 and flickering


Looks like the TV has developed dry solder/dry/shorting capacitors. To make sure, first of all try the same input device on some other TV. If it works there, you can be sure that your TV is having problems. Then I would advise you to stop using it to stop aggravating the defects. It is better to show it to a qualified service technician.

It goes back to the DVD menu. Some DVD menus have little animations of characters from the movie talking to you telling you to start the movie or something. You could definitely go somewhere with that. Also, some DVD players have a sleep timer on them so they turn off automatically or just show the start up screen which usually says the brand name of the device.

Sanyo 31'' Standard Def CRT TV


This is a vertical problem that can be as simple as poor connections at the vertical IC or a defective IC. If you can solder, you should be able to fix this yourself. Realize that there are potentially dangerous high voltages present inside hte set even when unplugged. If you wish to attempt this repair, please update this and confirm your model number as DS31590 and I'll supply additional details and instructions.

Try the reset on the remote. Press this key twice to restore factory settings. The TV will automatically start Channel Search and clear all customized settings. These features will automatically reset: ? Picture/Sound Adjustments: Color, Tint, Contrast, Brightness, Sharpness, Color Enhancer, Tone, and Surround Sound ? Channel Memory ? Audio to Stereo ? Caption to OFF ? V-Guide to OFF ? Aspect Ratio to 4:3 (normal) ? Menu Language to English ? Sleep Timer (if previously set) ? Video to TV (if previously set) If desired, personal settings can be made again using the menu options
