Zenith D52WLCD: After about an 1hr of having the set turned on, the picture would suddenly disappear followed by 26 blue vertical lines from top to bottom of the set with a light greenish background. Appeared to be over heating. After turning set off for about 5 mins then back on picture was normal. This happened about 5 times. The last time however the picture never came back. No picture or menu just the blue lines with green background. Replaced the bulb with no success. Found very little dust covering the foam dust filter. Anybody have an idea what might need to be replaced and a price estimate of the part. Bought 2003 very light usage. Thanks

Re: Blue vertical lines - no picture
You did not mention if you have sound.but if you have sound your problem is in your video and vertical section.if no sound then you have to look into the IF section.if you are not a tech then you will have to take your set to repairman.goodluck.the tuner must not be over looked.an estimate of about $200.00 could be less.

try this if you have the remote control, press the menu button continuously, The "OSD" menus will disappear then press the "9876" and press the "OK" button to enter "ADJ" mode you will see "Lamp Life Time" Then set the time to "00".
most likely a fault in the vertical deflection circuit or sometimes but rare, in the video circuit. Your problem could be a vertical registration problem(convergence), a bad vertical drive or verical output falure, or a fault at the sweep power suply that feeds the voltage to the verticle circuit. In my opinion, this repair, if it is what I think it is, should run anywhere from 200 bucks, all the way up to 450 bucks.depending on what has to be done. These sets have no user replaceable parts inside them, so trying to fix them yourself these days can not only be dangerous, but if you do not have the right training to work on these solid state sets, can also be alot of guesswork.
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!
