Don't see any other manufacturers doing this type of support...

This is what I wanted from Sony a month ago when I started calling about my 46XBR4. They said it wasn't economical to repair my TV ( 2 weeks ago ) and they are sending me a Refurb 46XBR9 with 1 year warranty for $300 +tax. Supposed to ship tomorrow. I could cancel and get the XBR4 fixed but I am on my 2nd panel already. I'm glad they are doing right by the XBR4 owners like they did with the XBR1s.

Thank you for posting this! Although I've not had any issues with mine yet (purchased 11/2007), it is good to know I'm covered.

That is correct. It only applies to the 46" size of the XBR4 and XBR5. If the panel has been abused or tampered with the service will not be covered. These are beautiful televisions and it is good to see that you will enjoy them for a longer time!

I just wanted to say thank you to everyone that posted in this thread . I recently got a kdl-46xbr4 from my local dump it has the tab bond issue and I was going to try to fix it with the "band-aid" fix but read down further and found out about the warranty extension and contacted my local sony repair tech and it is being fixed for free I would never have known if not for the wonderful people of AVS (who have helped me fix 2 other tv's ) thanks again

The one got it fixed and replaced from Sony were very happy and lucky. But as for me, I had very bad experience. Sony won't fixed or replaced for me. Because I had back panel opened, That cause to voice my warrently. If anyone know a good lawyer and refer to me.
Thank you

Hello.
New member with sony KDL-46XBR4 LCD TV and without warning or symptoms the TV started having video display problems. When you turn on the TV we most often get no picture and half the time still giving audio.
The display has always been outstanding with no blurr or lines or color vibration.
If you cycle the ON and OFF it sometimes finds the video again and looks normal....but only seldom do we get the video back.
Changed inputs from HDMI to Component and Composite with the same problem - no video and sometimes audio with no video...But again sometimes you get both video and audio with less quality using these inputs.
When the unit is showing no video you cannot see display when trying to change inputs...just get a black screen. So hard to tell what input you are sourcing.
Sony tells me it's a panel and not worth fixing. This TV cost me $3000 new Oct 07. I really don't believe in tossing such a nice unit cause of this display issue. The same comparable model from sony now costs about $4200.

Now as I write this submission the TV display suddenly come on...this after about 15 minutes of being on with no video, but still had audio...so now I have both again. Until I turn it off and have to go through the same game of, "hide and seek"

Thank you most sincerely,

Dale

I have a KDL-46XBR2 that I have had no problems with. My mother bought a KDL-46XBR4 and the screen is acting up. On different inputs the center to the right is all blank. If it is on TV the center is dark but not 100% and the right side is moving really slow. The black box at the bottom that says "No Signal" is easily read.



I was wondering if this is a tab bond issue or t-con issue or even something else.

Thanks,
Todd

I, too, bought a Sony Bravia XBR in December of 2007 and just recently had the same darkening problem as described in other
posts.

I think the analysis of tarnishing on some contacts is absolutely correct. It was taking longer and longer to get the picture
back to normal (probably because of the deepening tarnish issue.)

The picture was coming back once the TV had been on for at least 30 minutes.... in other words: heating up.
When the contacts got warm, they expanded and made the connections better.

Today I tried a quicker fix: I took a hair dryer and held it at the back right of the screen (where the darkness occurred.)
In 2 minutes, I had a perfect picture again. The hair dryer apparently just sped up the process that the heat from the TV would do but over a much longer period of time.

I realise that this doesn't solve the tarnishing problem but it is a short-term fix for those with this problem.

Boky, I just found this form while surfing as a result of my Sony 46inch when black last night. It turns on but nothing on the screen. I have someone coming out mid month to check it out but in surfing the forum you appear to be very knowledgeable. I was wonder if clearing the contacts would also solve my black screen problem?

After reading most of the posts. I decided to take my tv apart. low and behold its a tab bond issue. I used a piece of rolled up paper and scotch tape to keep pressure on it until i go get rubber bumber stuff. its working right for the most part. i dont think i used enough paper. i uploaded a vidoe of what it does when you are pushing on the tab. just for informational purposes i guess.
