i have white screen on this tv no matter which input it could be on cable /tv or hdmi, dvd,etc tv stays on white screen but audio is good.. how do i fix this??? the tv dont show channels changes or setup when using control just a blank white screen.

1) The set of input (Yellow= Composite video, Red= Right channel audio, White= Left channel audio). This set of input is for composite video.

2) The set of input (Red= Red video signal, Green= Green video signal + sync, Blue= Blue signal, Red= Right channel audio, White = Left channel audio (the Red and White will be grouped close together). This set of input is used for Component video for HD signal.

You should try using composite video source (Yellow RCA jack) from DVD player and feed to the monitor and see if it works OK with all color showing that way we acn find out if it is the video source problem or the monitor video signal processing problem. Try the PS2 on the TV if it works OK also.

You don't say what TV you have so it's impossible for me to guess what the connection it is that you are using. You will not see a signal on any of the channels you will need to select AV or Mode or Input or something similar on the TV

ok hook up the audio video in the OUTPUT on vcr and INPUT on the tv then make sure tv is changed to the right input channel now go to vcr and change that channel to AV,.if AV isnt there you may have to go into menu of vcr and do a channel search,but when you change it to AV on vcr you should see the picture

What model TV is it?
it may be you need to change the input to video 1 or video 2 to get those front jacks to work. if there is a TV/Video button on the front you should be set. If not you may need the remote control. Sometimes changing the channel to below channel 1 will give you that option.

the difference between tv and av, is that av has no showers on the screen. if you change to av you will notice a blue screen, connect your yellow on vedio output and white/ red on audio out of tv
note- before connecting to a vedio touch a tip of your vedio cable some lines will show on your screen, if touch your audio tip harming noise will sound on your tv. if this two happens then you know that your cables are okey. hold your channel button on your tv, channel will start runing after all rf channels finish, tv will go to av.

put the dvd player on the same channel as you set your Tv when wathing direct tv. and try recording

if you are using rca push on cable yellow,red ,white set to your A,V audio,video channel

when recordining you will be changing channels on the direct tv box

do you have a manual for dvd player read that really good that might help.

If the Tv turns on (power supply is ok), screen lights up (inverters are ok) but don't get a blue screen, menu options, source options, or audio, it's most likely the main board (aka Motherboard) is faulty. If a DVD player is hooked upto the TV, check whether you can get audio from that (change the source using remote), in such a case it could be a problem with LCD Interface board. My $3 is on faulty Main board.
