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.
