Hello good folks! I have a 50" Sony Wega LCD rear projection TV that has horizontal gray lines running through the entire picture. It does not have lines across the menu screen or when it is just on static. The image is real bad at first (rolling) but slowly clears up until just lines. Also, the screen is a little dark, although the lamp was recently replaced and the lamp error code does not come on. A Sony tech said it is not the Optical Block (for whatever thats worth) and not the lamp. I don't know what else to check. Interference from other things is unlikely although I do have a wireless router next to it. Any help would be much appreciated!!
Sony has had lots of problems with their rear projection TVs. I'd say to junk it. I had a friend who had the 70" Qualia 006 which retailed for $13k, he's been through 2 optical blocks and many lamps. These TVs are nowhere near the quality and durability of their CRT TVs which were king back in the day.
You may want to look at the AVSforums for some help, there is also a facebook page called Sony Listens that tries to make things right for Sony customers.

Unfortunately I have to agree with you on discarding the unit. It's similar to the Samsung DLP we had until it died last year just about this time of the year. The LED LCD set that replaced it is bigger, brighter, clearer and runs about 1/3 the power. The Sony and Samsung power consumption is very similar.

Thanks for the help, I looked at the thread suggested and found no bad caps but I do believe that it is a bad board involved. Unfortunately, Sony seems unwilling to help out. I have sent them several emails and spoke to their completely worthless customer service team (barely english speaking).This TV model (and a bunch more from Sony) should have been recalled. To add insult to injury, they offered me 2 different TVs at a "discounted" price. (A google search found that their was barely if at all a discount. In fact, I found some places that offered them cheaper). Sony? What gives!
Hello ISAACHUBBARD. I just inherited a Sony KF-50WE610 this week and it has the identical problem as your Sony TV. I would like to get it working for sentimental reasons. The lamp and Optical Block were replaced a few years ago. I have spent hours on the internet trying to find a fix and yours is the only reference to this particular problem. I have looked at all the caps and all look fine. I too believe it is a PC board problem and would be willing to buy a replacement Sony board. I am wondering if you have had any luck determining what the problem is. I hope we can stay in touch to figure out how to get our TV's working again. Thanks.
Fix for Green or Gray Horizontal Lines
There is a post at AllExperts.com (http://en.allexperts.com/q/TV-VCR-Stereo-1749/2011/9/sony-kf60we610-horizontal-lines.htm) where a guy with two Sony KF-60WE610 TV's (one working, one with the horizontal lines) swapped boards until the problem board was found. It was the DIC2 board contained in the DIC Block, a module mounted next to the Power Supply board G1. He mistakenly states that it is the LCD Control board. Before I figured that out, i ordered and replaced my LCD Control board (mounted on the Optical Block) and had no difference. After re-reading the post, I figured out what he was talking about and ordered a DIC Block assy/module. Unfortunately after installing the new DIC Block, my TV no longer powers up to verify it is indeed fixed. I am now fighting that battle. Maybe this will help someone else having the same issue with their TV.
