The onscreen menu does not rely on the color circuit to produce a color menu.
The most common issues with that symptom are bad color crystal on the main board or a shorted transistor on the main board next to the video jungle IC

Colors are bleeding into each other


Go into your menu on the TV and set the color in the contrast and brightness and sharpness of the picture!

Screen is bowed on top and bottom.


Projection sets have two very common problems outlined below.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. The TV can also shut down when the convergence starts to fail.

Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith, RCA and others.


You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

No picture, black screen


Not a TV Technician, use the following information at your own risk. Two things you can do first: using the keys on the front of your set press and hold the menu button when while holding it down it goes from menu to channel listing press the adjust (<->) and channel up buttons simultaneously to get to the factory set up screen once there use the select button to scroll to next set up screens locate the contrast it should range from 1-63 find the one you like. Second: for the horizontal lines not to say that this is the solution there are two adjustment apparatuses inside the TV chassis if your familiar with taking the set apart and not getting shocked and hurt59274cc.jpg two dials on the fly back transformer ones for focus the other brightness you can try these fixes but I have to say again that you use at your own risk. I do hope though that the information is useful

Change to channel 3 rather than 2 on Zenith 27" withot a remote


You can use the menu button on the front to autoprogram the unit. Make sure the direct tv is on so the tuner will pick it up. After that, you can program the direct tv remote to operate the tv. The reason the channels won't change is there are none in the memory

Zenith tv model # H27H38DT


You can get the installation guide for a Zenith H27H38DT free at the following location. Look on page 36 to go into the VIDEO MENU and set PICTURE PREF to PRESET. That should restore the factory settings, so try that first. If you go into the actual Installer Menu on page 41, proceed with caution.

Black screen...no color


On the back of the set, look for 2 controls labeled focus and screen. If the TV is working but you cannot see the picture, try turning the screen control up little by little and the brightness should come back. If this works then make sure the focus control is set so that the picture is nice and sharp.

Cant locate or adjust the the TV color


All the controls should be accesed thru the on screen menu,your remote should have a menu or display button and if you press it on the screen of the tv you should see a list of different options ,I am not familiar with the kind of menu that your set has but I know the color adjustment should be in the same screen that allows you to change the brightness,shapness,tint,color and contrast,the more you use the menu and become familiar with it the easiest it will be to use.Let us know if you need more information.

i dont know this exact model, but i can advice you based on a slightly diffrent model. i hope the solution will be valid for your model as well: TV is digital controlled and have to be adjusted via service menu except the external focus and screen on back of (flyback) high voltage transformer. This is one you can try: Need plastic allen or plastic small flat blade screwdriver to fit these. Focus is top, bottom is the screen that set the overall brightness. Before adjusting, go in menu: press menu once, select picture quality, I think number 4, press 2 for "preset..", press 2 again to select normal. Back out by pressing zero repeatedly. It may ask you to save new settings, select yes. If screen is adjusted too bright, picture look lousy (washed out) the blacks will light up (becomes grey, or visible lines) this means you have actual fault that prevents you to get decent pix, that when it is time to take it in for repair.
