Question about Zenith IQB56W10 56" Rear Projection Television

Open Question

Zenith iqb56w10 I had this TV hooked up to a HD cable box and it was working fine. Turned it on and it wouldn't show a picture unless I changed the cable box output to 480i or 480p. Next day, it worked in 1080i again, but then stopped. What can I do. I know how to access the service menu.

SOURCE: Zenith 44" LCD TV

The yellow spot is due to the BLUE LCD and/or lens assy cracked, reason, to much HEAT! The blue is the darkest color and hold the most heat, so it goes first, always! In some cases it’s only the lens, however most of the time LCD is damage to. Parts are available, however install and alignment is timely. Quick fix is the complete light engine, which for model# E44W46LCD is part# 3141VSN916C, which customer cost is $1,449.27, wholesale for about $1,065.21. Rebuilt, if you can find it around 850.00 to 950.00. However the rebuilt does not always look as good as factory. My advice, TRASH set. This part will fail again in about 3 to 4 years, unless you watch a lot of white video. Remember, on a black or dark picture, all three LCD are blocking 100% of the light, causing extreme heat within the light engine. It’s a bad design.

Hi my TV is ghosting and I cannot change the blue on my convergence. It will allow me to go horizontal but not vertical to adjust. Is there a reset on the TV? Zenith IQB56W10 56 in.

The most likely cause is shorted convergence chips and possibly a few pico fuses.

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. 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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*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

Input 6 - HD Input - Green Screen. Audio Only. No picture.

Hi there,
I am having a similar problem with the inputs. I have a cable box plugged in to cable antenna, DVD to video 6 using HDMI, Mac computer plugged in to video 7 - using HDMI (TV does not recognize this) and then Nintendo Wii hooked up to Video 1. My problem is that Sony only realizes 2 additional components like the video 1 (wii) and DVD on video 6, it does not play the other components. I have to niw manually switch the cables to have them work...

Samsung Rear Projection DLP HDMI Captions

The captions are turned on in the cable box itself. If you have a Motorola cable box, turn it off then hit the menu button for the cable box. You will then see where you can turn off the closed captioning. Anymore questions email me
