Green snow Picture has a green glow over it. It's not the tv signal as it's visible with DVD play. It sometimes goes away but usually comes back and stays.

SOURCE: TV screen turns off, green light stays on

As posted for a similar problem:

This is an issue with IC 803 on the Z board. This is a 3.3 V regulator that supplies this voltage to the slot card cage. Most input boards use this voltage EXCEPT the component board which is why it keeps playing along whike the DVI, HDMI, or composite signals will cut out after warm-up.

This is a surface mount multi-pin IC and is a bit tricky to replace.
The entire board is PN# TNPA3198xx with suffix determined by what model 7 series plasma you have.

This was a problem from around Nov. 2004 to Mar. 2005

SOURCE: green interference on Panasonic TH-PX75U

Since the set is only 8 months old, it should still be under warranty. This may only be an internal connection problem, but opening up the unit will void the warranty. I would suggest that you call for warranty service. This is a problem with the set and has nothing to do with external devices or interference.

Keep us posted.

it you have a repair skills you need to open the TV and make sure all the ribon connectors around the circuit boards are proper connected
and if all seems to be ok, the DG board will need to be replaced.

My DVD is playing my videos in black and white .. It's a Panasonic tv model is tc-L32c5


follow the steps. God bless you
Insert a DVD lens-cleaning disc into your player and press "Play" to clean the DVD laser, eliminating picture problems due to read errors. Do not use a CD cleaning disc as the brushes on these discs can damage your laser.

  • 2 Wipe your DVDs clean of all visible marks and dirt using a lint-free cleaning cloth moistened with rubbing alcohol or glass cleaner. This further fixes read errors which can damage the quality of picture and sound.


  • 3 Disconnect your DVD player from the TV or receiver you have it connected to. Reconnect the DVD player directly to the "AV" or "Video In" port of your television, firmly pushing the plug into place, to eliminate possible noise from the receiver and ensure a clean connection.
  • 4 Connect your DVD player using an S-Video, component video or HDMI cable. Standard yellow/red/white RCA connectors cannot carry the high-quality signal that DVD discs are capable of transmitting, and will display a particularly poor picture on flat-screen high definition televisions. Use an HDMI cable, if your television and player support it, or a red/blue/green component video cable.
  • 5 Press "Setup" on your DVD remote and enter "Picture Settings." Make sure your DVD player is set to display images in the correct screen format ("Widescreen" or "16 x 9" for HDTV sets, "Standard" or "4 x 3" for older square sets) and scan mode. If you are using a DVD player that supports "Progressive Scan" on an HDTV or flat-screen set, activate this setting; for older sets, choose "Interlace" if given a choice.

    Sounds heat circuit related, and if under warranty you should notify them before you have to pay for the tuner or sync board.

    Suggest that the CRT Purity has gone off

    Check that there is nothing magnetic near the set

    The CRT may need to be degaussed

    Or the degauss circuite is faulty this would require a engineer to look at

    Green Picture


    The problem sounds like one I had. If so, the cause is as follows.

    The Daewoo ouputs synchronisation information on the green channel of the RGB outputs (which are pins in the SCART socket) The Panasonic TV automatically preferentially selects the RGB input in the SCART rather than the composite video signal in the SCART. The video circuits in the Panasonic should ignore the sync on the green channel but instead interpret the sync as green signal information which means the adjustment of the green channel is upset leading to a very green picture.

    Possible solutions:
    1. From the TV, manually select composite video input, not RGB. This may not be possible - I think the TV automatically goes for the RGB if it is present.
    2. Disconnect the wire to pin 16 in the SCART socket. This is the signal from the VCR/DVD to indicate that RGB is available. Disconnecting it means the TV defaults to the composite video. This is what I did.
    3. Connect the TV to the VCR/DVD using component or S-VHS leads only.

    1)possible bad RF modulator (the small box the A or B signal first goes thru) 2)Bad tuner (mounted on signal board) 3)or missing voltage to run tuner You could replace signal PCB,but that gets a little pricey.
