Question about Panasonic TH-42PD50U 42 in. Plasma EDTV

1 Answer

No color on TV; screen cycles from widescreen to normal

The color on the screen began to shift to black and white; now it's only black and white. Also, prior to that, the screen seemed to zoom in, but now I wonder if it was switching between widescreen and normal modes. Any ideas? I tried checking for loose connections, but no luck.
Thanks,
Loree

This may be part of the power supply distribution to one of the circuit areas. If it is a power loss, it may be from the secondary side of the flyback transformer power supply distribution.

The areas of concern would be in the scan generator, and in the colour demodulator circuits.

You will have to take the set to an experienced service tech to troubleshoot for the exact fault and change the defective components.

Picture Size


Keep in mind that not all programs and show are in widescreen format. When set to normal, you will get those black bars on the sides because the program is sized for the older TV's. Some TV's will have a zoom option, but that will cut off some of the top and the bottom of your picture.

Until everything goes widescreen, you are stuck in normal with those black bars or widescreen with the fat people.

I hate distortion in my TV image, so I am perfectly fine with my TV on normal.

Good luck.

A/V in black and white


good day,

what video device do you plug in to your TV screen, DVD player/VCR or game console?

If you still have the owners manual of your TV screen, look for instruction regarding Color system or video system. this menu will allow you to change color sytem from PAL to NTSC or AUTO system.
most likely the reason why you have a black and white color from vidoe input is because of system color compatibilty from your input device to your screen.

Or if your using a dvd player, you can also try accessing the "setup" button and look for video setting. from the video setting there will be selection to choose from: PAL , NTSC, AUTO . always select "auto"
so that the color system of your DVD player can change from PAL to NTSC deffending on your TV screen system setup.

cheers,
mark

4.14.1 Understanding Viewing Features
Your LCD HDTV features four viewing modes and Picture-In-Picture (PIP)/Picture-by-Picture (POP) mode.
You can switch viewing modes using the remote control.
4.14.2 Viewing Modes
Normal Mode
The original 4:3 aspect ratio (1.33:1 source) is preserved, so black bars are
added to the left and right of the display image. Standard TV broadcasts are
displayed with a 4:3 Aspect Ratio. Movies in 4:3 Aspect Ratio may be referred
to as pan-and-scan or full frame. These movies were originally filmed in 16:9
(widescreen), and then modified to fit a traditional TV screen (4:3).
Wide Mode
When watching a standard broadcast or full-frame movie in this mode,
the display image is stretched proportionately to fill the TV screen.
When watching a widescreen (1.78:1 source) program or movie, the
display image fills the TV screen. If you are watching a widescreen
(1.85:1 or 2.35:1 source) program or movie, there will still be black
bars at the top and bottom.
Zoom Mode
When watching a widescreen (1.78:1, 1.85:1, or 2.35:1 source)
program or movie, the display image is zoomed proportionally to fill the
width of the screen. The top and bottom are cut off to remove most of
the source material’s black bars. This mode is good for programs or
movies with sub-titles.
Panoramic Mode
When watching a standard broadcast or full frame movie in this mode,
the 4:3 Aspect Ratio (1.33:1 source) display image is stretched
horizontally on the left and right sides to fill the TV screen. The center
of the image is not stretched.

Note: Viewing modes are saved based on input. For example, you lasted watched a DVD in widescreen
mode and then watched TV in standard mode. When you switch back to DVD input, the viewing mode
will return to widescreen.

Black and white format on 26" insignia hdtv (720p)


Go to Best Buy and see if they have your same Model on display and change the aspect ratio and see how it is. If it's normal there then to me it sounds like a software up-grade might be in order. It might just have a software glitch.

Turn down your color and see if the screen has a normal black & white screen. If it doesn't then the CRT is bad (picture tube). If it is black & White then you have a either lost your red or blue.That problem will be in your video driver circuit of which a service center can handle.
