Question about Zenith E44W46LCD 44" Rear Projection HDTV-Ready Television

A colour bar blue on the bottom and green on top of42" LCD

I am useing a HD box from Shaw Cablevision (made by Motorola) hooked up to a 42" Zenith LCD. Have good reception on both digital signal and HD Channels.
However I have a yellowish-green fuzzy bar 2-3" across the top of screen and a blue fuzzy bar 2-3" across the bottom of the screen. Have tried calling local service centre to no avail. Contacted Zenith USA as set was bought in washington state and given to me as a gift. They were of no help! Please send any hints or tips you can. Thanks

You need to replice the convergence ICs.

    It is a rear projection, not lcd, therefore it should be a convergence problem. Afull convergence test should be performed from service menu. If you still have the problem after setting up convergence, you will need to check the fuses at the base of convergence IC and change convergence ICs.

    My first answer was wrong, your model is a rear projection LCD TV, not a projection tv (the tube ones). Therefore it is not an IC problem.
    As already posted, it is likely that you need to change or adjust the lamp. Here are replacement in Europe, post your location to get more options:

    It is correct , you should not replace the lamp unless you are a technician or an advanced DIY. Lamp costs over US$400 and must be tested before being replaced. There may be many additional reasons why the LCD tv is displaying horizontal bars. May be a problem with some component on the main board, or a misplaced LCD display cable.

    Turn off all appliances aroun your tv, if you have an option for using a traditional uhf areal use the tv with aerial only, and check if you still have the bar, alternatively try moving tv to other room. Problem of this kind may be generated by disturbance from an heavy appliance nearby (fridge, big amp, transmitter), or by a defective cable.

    If you cannot get rid of the problem it may be neccessary locating a tv repair in your area.
    If you want to DIY you will need to start from getting the service manual with diagrams and part list, it costs $25. Here is also a forum on problems with your model, if you ask them they may get service manual for free.

    Regards

I turn on the Tv the sound comes on & the picture is blank Cablevision was here & said it's a problem in the set


He is probably not an expert (just kidding, of course he's not..) First, try connecting the Cablevision Box to another TV (if you don't have another HD TV, use the yellow/white/red Composite connection.) If there is still no picture, the box is no good. If there is, then try a different output from the Box or other inputs on the TV. Are you using HDMI (HD connection) out of your Box? Is the TV 720p or 1080p? Set the Box up (from the menu) according to the specs of your TV. Hope I helped.

The people are blue and we have no option for changing the colour


the component video cables are switched around. there are 3 colors for video - green, blue and red
two for sound - white and red

make sure you didn't swap the red cables, or swap the blue and red, this is most likely the cause of your issue, check on both the sat box and on the tv

let me know if you require further assistance

Colours turns blue and green from HD channels


The most likely cause of your problem is the cable box HDMI output. If you have some extra cables, try connecting the TV to the cable box using the component connections. I'll bet your problem will go away. Don't let the cable company lie to you; I work on Sony TV's everyday and see plenty of cable box HDMI issues. Some of my customers have exchanged their boxes 4 or 5 times and still have HDMI issues. Your best bet is to use the component outputs or switch to Dish or Direct TV, as they DON"T have HDMI problems. If this solution works, be sure to rate it. Thanks!
