Deflection Board Part Number

Your problem sounds like the projection bulb is going bad. It is the main problem with projection TV's, and is usually very spendy. I would recommend calling Zenith and request a new bulb.

some transitor is gone bad,you better send it for repair

mostlikly the deflection board is going out. and will need replaced

When you remove the back of the set. You will fined a couple of caps on the power supply board that are bulged and they need to be replaced, or you can buy a new power supply at www.partstore.com. If you want to just purchase the caps, you can get them at www.mcmelectronics.com

Go to the Zenith repair site. This has been resolved in a lawsuit. Zenith will fix it free of charge through 7/1/2010. The shop just picked my up to replace the light engine free of charge. Call 1-800-228-1757, have your model number and serial number, and where you purchased it. Here's the neat thing-the question I asked is "have they fixed the problem with the light engine, or is it going to keep going bad?" If happens again (blue lines/spots) before 7/1/2010, they'll replace the TV with a new and different TV of equal value!

Call LG electronics, they bought Zenith and fixed my 60inch Zewnith for free , my model is D60WLCD

out of focus

This sounds like a lamp failure. See your owners manual for instructions on replacing the lamp.
