SOURCE: Tv showing blue screen with flyback lines sound ok

Flyback lines? Is the picture all white with no brightness control with faint horizontal faint lines? If this is what you are saying, the screen voltage could be bad, and if thats the case, the picture tube or the flyback itself could be bad. You could also have a bad connection on the crt socket

SOURCE: rear projection lg lcd 44 inch

Is it an LCD or DLP? The Model below suggests it is an DLP. Sounds as if you have the dreaded light tunnel collapse common to all LG DLP TV's. Inside the light engine there is a square tube made up of four mirrors. These mirrors deform and crack with the heat of the lamp. They fall down over the light aperture and cause a shadow of varying degrees. It is fixable now at a realistic price ( used to have to replace engine) as LG have made the parts available. It would take a competent tech around three hours to complete or if you are technically minded you could do it yourself. I hope this helps. Good Luck.

It sounds like there is a problem with the tuner inside the television. Your best bet is to send it in for service.

How can i play ps2 on lcd without having a black and white screen ? how can i connect the cables ?.....when i look at the back of my lcd i find three ports (red white yellow) when i use them the screen is...


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.

New LG 32LD350 - Allowed TV to auto-program channels, and for some reason, it skipped past channel 4 during the tuning process. When I select channel 4 in the tuning options, it comes up as no signal. On...


When you are auto tuning the system will not store a channel which is week by its standard ( at least 60% signal strength ) This done to avoid grainy picture and hissy sound.
You can go into manual tuning and store it.

In just bought new Toshiba regza 40" Lcd tv and auto tuned it, but the picture is terible , snowy and colours are not good, what to do...


Hello
First of all reset the TV. for that

press and hold the POWER button
on the TV control panel for 5 or more seconds to reset the TV.
Then connect the TV tt any source like outdoor areiel or cable box etc, select the appropriate input, and retune the TV. First of all, connect it to an external antenna, and set it to autotune.

You must configure the ANT/CABLE input source before

programming channels (-left-hand column).

If the ANT/CABLE input signal type is set to Cable, the

automatic channel programming process erases channels

that were previously programmed into the TV's memory.

If the ANT/CABLE input signal type is set to Antenna, the

automatic channel programming process adds newly found

channels to the existing set of programmed channels (and

does NOT erase channels that were previously

programmed into the TV's memory.) To remove an Antenna

source channel from the memory, you must manually delete

it.

To tune the TV to a channel not programmed in the channel

memory, you must use the Channel Number buttons on the

remote control.

Programming channels when the ANT/CABLE input is

configured for Cable will take substantially longer than when

the antenna input is configured for Antenna. This is normal;

however, once channel programming is finished, you should

not have to repeat the programming process again unless
your Cable TV service lineup changes significantly.
Find out the received channels are clear or not. If they are clear, your TV is perfect, and the input device you connects ot the TV is faulty. OK.

TV signal problem?


look on the lcd website and see if there is an update for the lcd bios.
if you play a dvd is the issue the same.
try using a different connection to the cable box sometimes thats the issue.
try channel 3 /4
then composite video
then component 3 color
then DVI or svideo
with one of these you may see and improvement in video and sound

Vizio GV42L LCD TV screen black when turn TV on first time


If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on.  If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.

Check the signal type. It may be set incorrectly. Change the channel. You may be on a blank channel. Check to see if the TV is tuned to channel 3 or 4 if you are watching a videotape. Check the TV/VCR button on the VCR is in the correct mode by pressing the TV/VCR button on your VCR.
