Hooked up a Vizio sound bar and can't get any sound out of it. Vizio tech said I need to turn off the tv spekers. Can't find that feature in the tv menu.

That's part of setup. Go back to your setup routine (the menu that displays on the screen) and select SPEAKERS OFF

Either your inverter board or video board is bad. If you can see picture while the TV is on then its your inverter board. If not, video board.

SOURCE: I NEED A POWER SUPPLY AND CORD FOR A MAGNAVOX 15'

Either you can get this universal type available inthe market in any electronic spares store or it is easy too make one by yourself if you are familiar with electroncis.
All you need is a mains transformer with secondary voltage at 12 volt and 4 amps capacity, use a bridge rectifier , good storage capacitor of about 4700mfd/25 volts and if possible use a 12 V regulator so that the power is smooth, regulated and protected..

Hello,

power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Hope it work with the solution

Power Light


The most likely failure is the main power supply. You may be able to identify it with the following instructions:
Unplug your set overnight to allow potentially hazardous voltages to discharge, remove the back panel of the set so you can see the guts.
Look for a smaller board with larger parts on it; some cylindrical (capacitors), others block-like and relatively large (chokes and transformers).
You should also see a relationship between the board and the incoming AC.
Check the board for a label or if not present, a stamped-on number.
Call the manufacturer's service center with your TV model number and the number found on that board and inquire about repair/replacement costs; if both are offered, they won't be that much different.
If you must buy a new board, don't dispose of the failed one as there are smaller companies that can repair it for less than the mfr. and then keep it as a spare as this problem will likely arise again.

Unfortunately, the Magnavox name is owned by the Japanese Funai company which is known for poorly designed and not very reliable products.
