    Thanx for your response, but after staying up a while trying to find out what the problem could be, I found out that the underneath of the TV panel has five very small buttons. Clicking the end one marked "Source," alleviated the problem. Apparently the TV can be used as a computer monitor as well and clicking this button switches to either the TV or computer monitor mode. I still can't figure out what caused it to go into the "computer" mode.

    I've got the same problem, but pressing source does nothing for me. Still says no signal, and I cannot even access the menu.

    When I turn on the TV it says, "Attention no signal." Replaced the cable and had the same problem. All buttons do nothing - remote and on the TV.

The buttons underneath or the button on the remote marked source, did absolutely nothing. I think the set just died during operation and will be put to rest with other Phillips products.

I have a Magnavox 15MF400T/37 LCD TV operating with a cabel connection. As of yesterday it has no functions but when I turn it on I get a message that says Attention No Signal. I have checked the cable...


Some of the newer TV's dont turn on if there is no input signal. Try a DVD player and see if that works. If it does, then the issue is most likely with the cable jack on the TV, which may need to be replaced..

Magnavox 37MF331D/37 keep asking for software upgrade


Your set either has a bad SSB (small signal board) or needs a software upgrade. Try the upgrade first by going to http://www.m4c.magnavox.com/cgi-bin/dcbint/cpindex.pl?scy=US&slg=AEN&cat=FLAT_TV_CA&sct=LCD_LARGE_30_40_SU&grp=TV_GR&session=20090830171041_4.131.87.247&ctn=37MF331D/37&mid=Link_Software&hlt=Link_Software
Download the latest software release for your set then follow install instructions that are contained in the user manual for your set.

Magnavox 15MF400T/37 No Audio


Get a set of multi media speakers and connect them through the microphone plug in the back. I have mine set up this way and the sound is awesome. I purchased the Creative T-10. Can be found on ebay for around $15 + shipping.

Screen says attention no signal


Your TV is probably on the PC mode and you are not using it as a PC monitor.

You need to change the source by pressing the TV/Video button on the remote control or the SOURCE button on the TV itself. You may also just press the channel up or down buttons. Do this before the TV goes to standby mode (amber light) or while it shows the message: ATTENTION NO SIGNAL.

If it does not work, reboot the TV first and do this again.
