Magnavox 20MF251W won't turn on at all

The Magnavox NH400UD is a remote that included with select TV models, including the Magnavox 50M412B/F7. It is not a universal TV remote. The functions are locked to the original TV (or its sibling models). To see the instructions for using the remote with the original TV, see the documentation here: https://www.p4c.philips.com/cgi-bin/cpindex.pl?ctn=50MF412B/F7&hlt=Link_UserManuals&mid=Link_UserManuals&scy=US&slg=ENG .

You will have better luck getting a universal remote control to work with your Samsung TV. Just make sure that the remote is newer than the TV by 6 months or more. It usually takes six months for new codes to reach the universal remote control manufacturing facilities.

I wish that I had better news for you.

This is the setup code for your Maganavox combo. 0456

power supply problems does it have a separete power supply if so you can try to change or if you have someone with the same you can ask to try it.if its internal power supply it needs to be fixed.

Mine was doing the same thing. Update the firmware and it fixes the problem. Updating the firmware is done by downloading the file to a thumb-drive from the phillips product support page then plugging in the drive into the side of your television and turning it on. See your manual for slightly better instructions.

It may be touching in the back of the tv on a power point. Yours is doing the same thing mine did before it finely all most burnt up it self and my house The metal casting that the tv mounts on in the tv ,does not have enough room in it. the metal casing touches one of the power supplys in the back and shorts out. If its like my 32'' magnavox flat panel

there are none on my list, you can try to google DVD Hacks or region code with make and model

GO to Magnavox Owners Manual---on the www.

Try the Philips codes as well...

On those particular Magnavox TV's you have to use the original type of remote to power it back on then un-lock the parental lock. It is a bummer that nothing else will work. Here is a link to purchase a replacement remote.. http://www.electronicadventure.us/Merchant2/merchant.mv?screen=prod
