TV does not turn on? (Relay problem?)


The power supply could be failing intermittently. That's why it sometimes works and sometimes doesn't. Also, the relay could be erratic.

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.

I CANT GET OFF THE SET UP SCREEN , MANGNAVOX 47" TV, NO UNIV. REMOTES HAVE WORKED, PRESS THE GREEN BUTTON TO PROCEED?


The TV was turn ON for the first time or the TV reboot/reset.
Universal remotes are not as "universal" as we like them to be. They only control a very, small amount of options for the TV.

You'll need the remote that came with the TV to fix this problem because it has the special RED, GREEN, YELLOW, and BLUE buttons you need.
If you don't have the original remote, you can get one at this web site. It's the best price going right now. $29.95
