Question about Zenith IQB50M90W 50" Rear Projection Television

Zenith IQC50H95W displays in monochrome

Hi
Just noticed a new problem with this set - when connecting any non-component-video source to any input, it displays in black and white. I hadn't noticed because normally the only devices connected are the HD cable box and progressive scan DVD player and those both display nice color via YPbPr, but now I've found that when connecting anything to the two antenna-in jacks, the rear video inputs via composite or S-Video, or to the front video input, it all displays in black and white. Any thoughts? Thanks! -paul

    Tried that. It didn't work.

  • pdieten Nov 19, 2008

    Tried leaving it unplugged for 30 minutes then plugged it back in. Everything is still black and white except component video.

  • pdieten Nov 19, 2008

    Okay, I see the new offered solution. What does that mean and will it be expensive to fix?

  • pdieten Nov 20, 2008

    Not a PAL problem, this happens with everything I plug in via RF or composite. I tried a Zenith DTT900 converter box. It displays black and white. So does my basic cable connection. Everything is B&W except video input via component. I don't see anyplace to set PAL on the TV anyway.

    OK. I don't work on electronics made after the tube era, so I'll have to call the shop. I just don't know what such a repair might cost. Thanks much

Hi,

Since your general location is in the United States and Zenith being predominantly designed/marketed in the US makes this unit purely an NTSC color system. Having said this, then color system selection (choices of PAL, SECAM and others) need not be considered.

That would leave us with the one of the boards which is responsible for deciphering and embedding the necessary color to any video signal that passes through RF, composite Video and/or S-video. Component level wise repair would involve check of the ICs, the 3.58MHz crystal and other components. To verify, voltage checks should be performed on a live set with the back open. This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Sir,

It's possible that there is difference between the NTSC and PAL encoding on the DVD and your TV playback. If your TV/DVD is set to PAL, NTSC DVDs will be played black and white.

thanks
goodluck

It suffers from the same progressive video bug as the Hitachi where the RPTV video shuts down during sudden screen intensity transitions like the inputs were being overloaded. The Pitch Black trailer on the U-571 DVD is a prime example of this bug. No VGA connector for use with the RCA DTC-100.

Either the 2nd input color system is not properly selected or a fault arose in the chroma section of 2nd input.

My picture is in green. The convergence seems to work just fine. Why would my screen be green?


You might have the yellow for video, white, and red for audio (composite connection) plugged into the component plugs green, blue, red for video, white, and red for audio (component connection) somehow combined together on the back of your TV to whatever source your watching.
It should be color to color from your source to your TV.
It's that or only the green plug is plugged in for the component video. Hope this helps.

Hello

Change the channel to ensure the problem isn't with the current station broadcast. Check the channel at a later time to see if the broadcast problem is resolved.

The type of programming you are trying to watch determines the proper input source. Press the "Input" button on the remote control to change to the proper input source. For example, if the source is a cable or satellite service, press the "Input" button until "TV" mode is selected. A component device, such as a DVD player, will operate on a different input source, such as "Video-1."

Check the coaxial cable, which connects your television broadcast service provider to your television. You need to securely connect the coaxial cable to the "ATSC/Digital Cable In" jack on the back of the television, and the other end to the wall jack. If the cable appears damaged, replace it with a new cable.

If you are using a component device as the source of your programming, ensure the component cables are plugged into the "Video Input" and "Audio Input" jacks on the back of the television or that the S-Video cable is plugged into the "S-Video Input" jack on the back of the television. Connect the other end of the cables to the "Video Output" and "Audio Output" jacks or "S-Video Output" jack on the component device.

How to program the autio vidio inputs for zenith tv


Hi cathie
If you have sound it means that the tv is in aux/video mode.
Now make sure that the video output of the vcr is connected to the same aux/video input that has the sound connected to. i.e input 1 or 2 .
Also you want to try and switch with another cable to make sure that the cable you are using now is o.k.
Another way to try the tv input would be to connect something else in that input(cable box ,dvd ,video game etc,)
Try it and let me know.

How do you hook up tv to computer to play netflix off computer


Based on the model number, Zenith manual shows a VGA connector on the back. So if your video card has two connections then one can be sent to the TV and it becomes another monitor to your PC. Enabling the monitor is usually done through Display properties in your control panel. If you don't have a 2nd connection then connect the TV directly to your VGA output and let the TV be the primary monitor (select that input through your remote's source or input button) then boot the PC. You should see the PC video and boot process on screen. From there you can play Netflix or video games (Warcraft is awesome)

To get the manual for your model go to the link and fill out the requested info. You will need to dload a reader for the manual to show up.

Powersurge made my HD setting revert to low def.


Your TV plays High Def material through either Input 4 (uses component cables R,G,B) or through Input 5 (Uses DVI cable).
Today most equipment uses HDMI cable for High Def or it may have a component (RGB) output that you can use. The DVI hookup is best, so you need a HDMI to DVI cable or Component Cables (Red, Green, Blue). You need some source that OUTPUTS High def (ex. 1080i) either through HDMI or component cable. You need to either connect the component cable(R,G,B) from the source to the Input 4 on the TV or connect the HDMI to DVI cable from the source to the Input 5.
You need to set the AV source on the TV to AV5 (if you are using the DVI input) or AV4 (if you are using component cables).
If you want to play Highdef source like Blue Ray then you can just connect the output of the blu ray player to your Tv using either the HDMI to DVI cable or component cable (Red, Green, Blue) and set the TV input to AV5 (for HDMI/DVI) or AV4 (for component).
But if you are trying to get Free High Def from an antenna then you will need to have a component that can OUTPUT high def. The $40 converter boxes don't do this - they simply convert the Digital signal to Analog (non high def). What you need is a High Def TUNER that OUTPUTS High Def. I was looking for one for this same reason and ordered the centronics ZAT 502 HD. But it cost about $80. Then I saw that Tivo had an upgrade deal where I could upgrade my existing Series 2 Tivo to Tivo HD for $99. It has a High Def Tuner in it. So I cancelled my order with Centronics and got the Tivo. In any case if you want Over the air HD you will need a High Def Tuner that will OUTPUT 1080.

Convergence problem - NOT STK ICs / resistors


have you check the electrolytic filters. check the video IC. also check the polyster or disk type capacitor, because they hold the frequency. in on screen mode the half of section is dead, but when you applied a signal it start converting it display mode. every signal is extracted from video signal in TV mode. the best way to check all this properly you need a colour pateran generator. when you used it you will find a fault and the area.
best of luck...

TV projects a pink/green shadow


Logically proceed one source at a time = disconnect all,
then hook-up one at a time or hook-up seperately.FYI, the
RF coax , composite and s-video inputs all share the same
circuitry, whereas component is a whole seperate video
processing circuit, with another difference between 480P and
1080 I . Sounds like you have a 1080 I problem, which might
be a little sister board..............................T.

Let me know..............Thanks.

Component Video inputs do not work


I started back in the day of tubes. A family would have one set and it would be a 19" black and white. There are different resolutions now. The components probably do work, but, they don't pass the 480i signal. The satelite converter's analog signal needs to be set to 480p and the DVD needs to be set to progressive if it does have that setting. If the DVD is not a progressive scan DVD, then, the only inputs that it will show on is the analog signal. Some of the dish converters have a switch on the face for changing the resolution. If yours doesn't then put it in an analog source and go to the menu and change it there. Then move it to the component input. Hope this helps.
