Screen changes between color as a demo function.no signal
Gateway was sued Class action over LCD's and Plasmas they sold over a 2
year period. They resell 3rd party TV's that were very faulty, an
Here's what I learned about mine, which makes it limp through as a
Computer monitor (both DVI and VCA) and halfway functional TV.
You have to connect a DVI source, on the Main Menu for the DVI input
there is an option called "Factory Mode". scroll down to it with the
CH buttons and select it with the vol button. The scroll to
"initialize eprom", select and confirm it. After the "Waitting" words
disappear, make sure you have a TV source connected, Then turn the TV
off and on, using the hard switch in the back. The TV input should be
defaulted to channel 10 or 11 now But you select a TV channel that has
no TV signal on it (like channel 1 for example) , the whole TV input
side will refuse to let you select it again, and you'll have a blank
screen and have to start over.
That takes care of the blank screen thing Now the other problem is
parental control is defaulting to "ON" or something, and you can't
program channels. With the TV input Main Menu engaged, select "Setup
Menu." If you have this problem, then you'll only see 2 options, all
the TV input and channel programming options will be missing. You have
to select Parental Control, and when it prompts you for a password hit
the volume > button 4 times (or just wait for a minute.) This
should bring back your TV System and auto prgram/manual search options.
Unfortunately, my TV doesn;t remember these setting very well if I
select cable, it does better if I select "AIr". But at least it
funtions - kind of. If you switch to your computer input, you probably
will have to switch the monitor off and on from the back panel again.
Mine always starts up with the menu onscreen. All this might bve less
trouble if you have a the remote, I don;t know where mine went after
the last move.
Good luck, and hope this helps.
