Vizio 42", have picture for about 5 mins then screen goes black.

if you go into your channel map (the area in your setup menu where you can add
or delete channels from appearing when you channel surf) the tv does NOT save
your channel map settings once you turn your tv off. this can become EXTREMELY
annoying if you have channels you don't want to surf through or have analog
channels that don't come in well. i have to go to this menu every time i turn on
the tv before i start watching, and delete all the channels i don't want to see
before i start channel surfing. and then once i turn the tv off and turn it back
on, you have to repeat the process again. it is sad that i have gotten extremely
quick at doing this since it is not something you should have to deal with on a
daily basis

2. another function that does
not save your settings on the tv is the delta volume setting in the sounds menu.
if you have channels that are at different volumes, this setting is supposed to
allow you t oadjust each channel's volume seperately so that when you surf, you
don't come across one channel that is whisper quiet while the next channel is
extremely loud. this is extremly apparent when switching between inputs, and
also between analog channels and digital channels. the most annoying part about
it not saving this feature is that once you set the delta volume and change the
channel, the setting GETS RESET TO ZERO! it renders this feature useless if it
does not save right when you change a channel. what is the point of this feature
then? why not just use the regular volume control?

3. once in a while, the tv will stop working. i have had it for
3 months, and sometimes i change the channel and all of a sudden the tv screen
goes black. it seems to freeze up. you can't turn it off, change the channel or
anything like that. you can't even turn it off by pressing the power button on
the actual tv, you have to unplug the power chord, and then plug it back in and
turn the tv back on and then it functions normally again

Number 3 sounds like the same problem that I have Number 3 sounds like the same problem that I have

any of the IC or the capacitor has got loosed on the power supply board.remove the board and check it out.and if every thing seems proper then just cold solder whole board and it will be proper.as the soldering joints are getting loosed after some time .so cold soldering will help. any of the IC or the capacitor has got loosed on the power supply board.remove the board and check it out.and if every thing seems proper then just cold solder whole board and it will be proper.as the soldering joints are getting loosed after some time .so cold soldering will help.
