Question about Sony KDL-46XBR4 46 in. LCD Television

Blank Screen on Sony KDL-46XBR4

This LCD has worked flawlessly for the past 4 years. I unplugged it a few weeks ago and took it off the wall. I sat it on a couch in the upright position. When I hung it yesterday at first there was no audio or video. Then it came back. Last night I lost everything again. What I do get is a green power light and a very light grey LCD screen (back-lights?) I unplugged the set overnight and tried it this morning. I worked fine until I turned it off then on. I lost video but not audio. I still get a faint grey screen. It sounds like a connection or a bad board. I'm confident doing the repair myself.

I have coloured vertical lines covering my Sony Bravia LCD tv screen. The TV is only 2 years old. I have sound but a very distorted picture. The cable company has checked and says it's a tv problem. I will...


I also have a 2 yr old Sony KDL32xbr4 that now has multi-colored vertical lines on the screen. I contacted Sony and they say they have "no known issue" of this sort for this model. I find this rather puzzling since I have found numerous postings on the web. They told me to try the factory reset. Whatever. Might as well have said "don't buy a Sony". 2 years! $1300 for a tv and it lasts 2 years! Makes me sick to my stomach.

Sony kdl-46xbr4 Black Horizontal Bands When I First Turn on TV


I had the exact same problem with the Sony KDL46XBR4. The problem started 11 months after I purchased the TV (Dec 2007). Luckily I placed the call to Sony just before the 1 year warranty expired and they replaced the entire front panel which is basically the whole TV except for the stand and the plastic frame. Last month the same issue started happening again (5 months since the repair). I called Sony and they say they have a 90 day warranty on the replacement part so I would need to pay out of my own pocket to first have the problem diagnosed (it's the EXACT same problem!) and then pay to have the repair done since the warranty has expired. I asked how much the front panel costs and it's $1,400! I paid $2,100 for the TV when I purchased it. Interestingly, at the time that part was back-ordered.....hmmmm, I wonder why??? Perhaps a recall is warranted here (no pun intended). Needless to say, I have sworn off Sony products due to their lack of support for this issue.

LCD Displaying Red instead of Black, Vertical Lines in Display


I had a similar problem where the screen went to a pink shade periodically. Sony sent me a memory stick, with download instructions, that fit into one of the back ports. The problem has gone away. It was a software correction.
