An earlier post of the smaller model of this with the same problem said to remove the metal cover over the power supply.

I have the 26MF231D and it worked great afterward (even though you can't mount it)

Here is how you remove the cover.

Most likely you will have to replace the power supply. It is a very common problem especially in newer electronics. You can test it with voltmeter or multi-tester. They tend to get worn capacitor inside the power supply due to cheaper parts

SOURCE: 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.

Yes, he means 2200 microfarret (called uf from here on out). Another important concern when buying a replacement is the voltage. You need to get something that is at least 25v. I recommend a 35v or better. Another notable point is that this may not always fix the problem. As with mine, there was also a 1200uf (microfarret) 35v capacitor that was blown. You can tell this because they bulge at the top. I have both of these caps (2200uf 35v and 1200uf 35v) on order and they will be here tomorrow. If I do not post back here then they fixed the issue for me. I suspect that this will resolve the problem. Look for bulges on top of the caps. This is an indication that they are blown. Most all of you experiancing these symptoms will see the 2200uf cap bulging but you may also see others bulging too. If you do then you need to replace those too. No electrolitic capacitor should be bulging at the top so if its bulging its bad, and if its bad then your tv will definitely not work. Have fun.

The problem can be in the backlight inverter board (hard to get to), or the main power supply module may not be working. Look at the power supply first since it is easy to get to, look for burnt parts, bad capacitors.

2how to get around large base that sticks out too far to use a low profile mount to mount my magnavox 26MD357B/37 hdtv


Apparently you need some kind of MOUNTING SCREW EXTENSIONS to mount your tv to the wall.

You will need to contact Philips Customer Service at 1-800-705-2000 to order them.

See page 5 of your tv's USER'S MANUAL at the following link:

My tv picture is light and hard to see and will periodically shut off.its only abput 5 yrs old/


For a Philips LCD TV, that's at least two years longer than they typically last. The most common problem with Philps TVs is the power supply board, which could cause the TV to shut-down by itself. The picture being too-light could happen for several reasons. In general, a repair shop needs to figure out what's wrong.

I don't know why but this got my TV on.
I took off the back cover and found the source of the clicking.
Two blue plastic rectangular relays in the exact middle.
When I pushed the power button, I felt the top relay click, and I saw a flash from the bottom one. (they are right next to each other)
I took a hair dryer and placed it over the two relays for about 1 minute and tried the power.
It clicked only 4 times and then came on!!!!!!!!!
For some reason heat helps the relay.
If anyone is a tech and can explain this, please do.
Good luck!!!!
My tv is on and it didn't cost me anything.
I just can't turn it off now!!!
