Check and replace the power supply board. It might be faulty. Normally, there is no service to these boards. Only card base replacement can be done, and it is good too.

Check the power supply part no. matching. If there is adjustment potentiometer for the supply voltages try adjusting to the required level of the voltage.

The menu keeps flashing on and off. I have turn the tv off 4 or 5 times but it still keeps flashing the light on the bottom of tv goes blue then red really fast


How old is your TV? This normally indicates a power problem. It could be any of the following: power supply on the TV, faulty power strip, faulty wall outlet, faulty circuit board inside the TV, faulty power cord/plug, bad airflow/clogged vents restricting air movement into the TV (can cause intermittent power faults),bad sensor inside TV. This is not completely inclusive by any means. It does mean that you should have it looked at. Someone knowledgeable/skilled should be able to determine the cause fairly quickly using a multimeter.

No power to my Vizio TV


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.

Tv was plugged in and off, but when turned on, it made a real ( I mean really loud) piercing noise and the tv just went out completely and there was like a burning sort of smell so we unplugged it and...


It could be anything, sounds like either a power supply issue or a short circuit, dont try and turn this back on as you will only do more damage, unfortunately the only solution is a professional repair and that may not even do it, smeeling burning usually means something died inside, so it wont be cheap. sorry to be the bearer of bad news

My Sanyo was playing good one day then the next day it wouldn't do anything can you help


Good Morning

Let me try to help. When you say "wont do anything" does that mean no power lights? If so it could be that you dont have power to the tv. I dont know how yours is hooked up, but if you have other devices (cable box) on the same outlett and it works then clearly you have power.

If you dont have a power light, then you probably have a bad Power Supply Board. They are not
extreemly expensive, but its not something you replace if you dont know what you are doing.

I hope this helps you

You can eithern have bad backlight inveter board, or bad power supply for the inverter board. Those are the two places to look first.

TV turns on...displays Polaroid then shuts off. Sometimes i can't even get it to the Polaroid point just turns on and turns off.


You have a bad power supply, call a local tv repair man 2 fix it for ya. Unless you think you can do it urself, but recommended a professional takes a look, dont want to damage anything else in the tv or hurt urself

I have power, but no sound or picture


djchillsync is correct - the power supply on these are really poorly engineered and made. Audiovox is trying very hard to ruin thier reputation by putting ou **** like these sets. Contact them for warranty repairs, you may not get them paid for but you'll be directed to someone that knows what they are doing.
