The only appliance in my house I purchase an extended warranty for is the big TV(s). Also need to research where you purchase the TV from to ensure the warranty you are purchasing is good quality. Somewhat of a PITA.

If you have vertical lines on the xbr8 it probably is the FBU board which doesn't seem to be available anywhere. Try going to picture adjustment and scrolling Down to the DRC mode and turning it off. It may help to get rid of the lines. The pic seems pretty good without the line doubling and may get you by for a while. You will need to do this for the different modes if you use standard, vivid, etc. it has helped us but now the sound sometimes fades in and out. Hoping to get by until the 4K comes out and the price comes down. We have an xbr850 and the pic just isn't as good as the xbr8. Maybe the new triluminous will be as good as the xbr8 or better yet an improvement. We loved the 8 before the board went bad.

That's really interesting, about DRC mode... Thanks for posting that.

I understand Sony will offer one of the HX9's as a replacement?

By the by, I read through all the forum posts and its about page 175 when the failures start to appear.

I'm having a problem that sounds like yours. Video here.
At the suggestion of a tech I replaced the CB1 board (top center on the back of the panel below the TCON board) and it didn't change anything. Then, willing to try anything, I ordered a replacement TCON board and tried that. Unfortunatly I got a bad TCON board. The far left of the four connectors at the top had loose pins so have the screen was out but the other half still worked and the problem was still happening so I feel comfortable ruling both those out. I haven't tried to replace the FBU yet because it's more expensive and turning DRC off didn't change anything. Can you tell me if your problem is similar to mine from the video and whether or not you've done anything that helped?

My set has the vertical line problems. No horizontal,lines. Looks different than your problems. When I called sony they had me reset the tv, unplug and reconnect all the cables and check to see if there was a different picture thru the bluray then the tv itself. Nothing worked to fix the problem but menus were clear. One tech said many of the displays are failing because the glues are separating in the panels. Supposedly in other countries sony extended the warranties to 3 years but not in the US for the XBR8s. the FBU board is what I read in various posts is the source of many vertical line problems.. problem is they are sold out everywhere. Only a few used boards occasionally appear for sale. I am not willing to pay a couple of hundred for a used board with no warranty and then pay for a tech two or thee hundred more to install so we are limping along. turning off the DRC mode helped but we had to do it multiple times to turn it off in all the different settings since the set used it for vivid, standard, etc. are your menus clear or lined? Can't believe this is happening since these sets cost a small fortune and they are only a few years old. I read one post that it could be a poor cable feed. i Called Brighthouse and they were scheduled to come out to check mine before I turned the DRC off.
post #5350 of 5434
Yeah the issue with mine always happens. Whether in the menu's or not. Analog or digital. Doesn't seem to matter
post #5351 of 5434
My 55" and 46" XBR8 purchased in Nov 2008 are both still going strong and I hope to get at least another 5 years out of them. but because of the cost of these set and the problems many folks are experiencing with them and Sony's attitude, these will be the last Sony TV's I will ever buy.
post #5352 of 5434
I wrote Sony in my country a letter about this problem eventhough my 46X4500 is working 100%. They told me that in case such thing would happen i might get some form of coulance (leniency).

Shopjimmy.com had some fbu boards in stock last time I checked, couple of weeks ago
post #5354 of 5434
My 55" XBR8 purchased in May 2009 has the vertical line problem. Right side of the TV has Vertical lines from top to bottom. There are 7 or 8, small Black lines running from left to right on the bottom of the screen. The Best Buy Geek Squad is going to come and repair the TV this Friday. I had only 3 weeks left on my extended warranty when this happened.

XBR8 is a beast!

Its the original 2008 review. Only the rating is updated (rating is also done several years ago). update -> They changed the look of the review a bit wink.gif
post #5357 of 5434
Whatever. It's black level still bests the Kuro, and the review is as true now as it was in 2008.

Yeah they lowered the score, lol. I don't get why they bother doing that, given anyone looking at the TV would have to know it's several years old and the rating should be treated as such. Stupid Cnet.

All these failures after only a few years are scary though. My 46XBR8 I hardly use so I dunno if it's going to up and get the dreaded lines problem one day frown.gif

Sony is pretty good at compensating people with discounts on a new set when the problem is widespread; but sucks that this might be a very common problem area on this set when it's so good. I already went through the whole SXRD thing, so another high end Sony set with problems is not very reassuring. Electronics (Sony and otherwise) certainly don't last like they used to. I think the days of having a TV work for 10-20 years are no longer.

I know that the XBR8s sold in Can/US, some were made (assembled) in Japan and some in Mexico...but did the FBU boards all come from the same place? I wonder if one is more reliable than the other--if the boards were made in different places, it's a possibility one may be less prone to failure . Those with problems might want to mention if their particular set was MIJ or MIM (or elsewhere if that's the case).
post #5359 of 5434
Technician who came to check the TV told me that my LCD panel is dying. He said he will recommend the company to change the screen. He also told me that the LCD screen is very expensive and not worth changing it and they might give me another TV or give me credit towards a new set.
Now I am waiting for the response from the Geek Squad. My set was assembled in Mexico.

Whether its the screen or the FBU board, both are difficult to source and expensive. FBU board can be verified via confirming menus and usb stick with pictures play ok. If they dont, likely the screen.

Did you mean FBU board?

Why is it called "FBU" anyway, I wonder what that stands for? Seems like "input/output board" might be a better way to describle it from the components it has.

A new FBU board is probably extremely hard to find, and a used/salvage one...well it may fail in time all the same frown.gif

I wonder if something(s) just needs to be reflowed on the FBU board? Anyone willing to try out the ol PS3-board-in-the-oven method? LOL. (For those that don't know, this was a way of "fixing" older "fat" PS3s which failed with YLOD--puting the motherboard in the oven at a specific temperature with solder flux, allowed some people to successfully do a DIY reflow and have a working PS3 again.)

^^ don't know what FBU means yet (Front Board Unit?). FBU board is the Digital Mainboard. It processes the external inputs from digital inputs (HDMI, Ethernet).

Sorry - FBU board. By the by, I replaced my own successfully using this manual.
post #5364 of 5434
Hi Everyone,
I am an owner of a KDL46XBR8 and have been very happy with everything about it since I bought it back in 2008. Suddenly when I go to turn it on.... it comes on for a quick second then goes right off and then I get the blinking red light in a series of 6 blinks. Long story short.... had a TV tech come out and said it was the FBU board.
I found 1 person in Canada who was advertising he had the board (used but tested and working) and bought it. Well it arrived the other day and to my disapontment after I installed it.... I had the same problem.
BUT since then I have discovered that the board that he advertised and said it came out of a 46XBR8 is a A-1557-719-B which is actually for the 55XBR8 not the 46XBR8. Both boards look identical except of course for having different part numbers. I don't know of any 100% way of testing the board I bought to know if it is bad or good but now that I know it's the wrong board for my TV... I have to assume this is the reason I'm still having the same issue.
I have not been able to locate the correct FBU board anyhwhere (A-156479A).
I even had the thought that since they look identical..that they might be interchangeble.
Any input is very welcome.
Thanks!

Our XBR8 46" just started having the vertical line (FBU) issue a couple of days ago. Anything through the HDMI input (and probably other input types) had vertical lines, but the Sony configuration menus were clean. Someone on this board suggested turning off DRC on all display modes and that fixes the problem completely. Have been running for 2 days with no issues. I guess I will eventually replace the FBU, but shutting off DRC works (wish I could find the post to credit the user who suggested it).

This is the comment about shutting off DRC in my post just before this one. Thanks Mindy -- this worked perfectly on our set!
post #5367 of 5434
Fellow owners of the XBR8, I would like to know if anyone has tried any of the new 4k master bluray's WITH the expanded color (x.v.Color). I know the PS3 is compatible, the XBR8 is compatible, and the disc is compatible, I also understand it's more meant for Sony's new line of XBR's, but given the money we spent on this in 08 and the fact it has the x.v.Color feature, shouldn't we be able to get in on the expanded colors with one of these blurays? I should be able to answer this on Tuesday as I ordered Angel's and Demon's 4k master with expanded color to test. Have any of you tried the new expanded color blurays from sony?
post #5368 of 5434
It appears it should work since our TV is hdmi 1.3 compatible, has x.v.Color option that can be enabled, the PS3 can also enable this option as it too is compatible, and as long as the receiver is hdmi 1.3 compatible, which in my case is the Onkyo TX-SR605, we should be able to enable the expanded color in the bluray with no issues. I'll confirm this on Tuesday and let you guys know. My only concern is that our TV's are REC709 which I had my TV ISF calibrated back in 09, so I'm curious how this will go, though the tech that did the calibration only used the TV's simply menus to match the color up instead of going into the service menu's so if I need to calibrate to the new expanded color, I may try to figure out the best settings. Wish me luck fellow XBR8 owners! It appears we will finally be able to use that useless feature which may turn out to be a true future proof for another year or 2!
post #5369 of 5434
There will probably be some effect on a 4K Sony Triluminos which is not the same as XBR8 Triluminos. I did read some CNET comment on that.


A guy tested Mastered In 4K discs using a Samsung LN46A650, PS3 and Sony BDP-570 (all said to support the xvYCC color gamut)
Quote:
...the colors on screen became ever so slightly subdued rather than expanded. I'm not sure if this mode was being engaged properly or not, but if that's the intended result, then I don't really see a benefit to this feature. Though the packaging doesn't specify this, there is some speculation that in order for this feature to work correctly viewers actually need a Sony TV an Blu-ray player that support the company's proprietary Triluminos technology. Those with that capability might find better results with the disc's claims of ''expanded color,'' but based on my experience with my equipment, it seems like this feature is a bit of a waste.

post #5370 of 5434
Has anyone contacted Sony about the white vertical lines? They just started showing up on my 55" XBR8 last week, on the 2 HDMI inputs being used, menus look fine, PC input looks fine.

I wonder what Sony says? This was supposed to be a top of the line product for Sony. Having it fail in 4 years of use sucks for the top of the line. Disabling DRC causes problems with deinterlacing (480i, 1080i signals). This statement is from the Home Theater mag review. They said without DRC, deinterlacing and line doubling performed poorly. But the review went on to say that most people won't see problems if DRC is turned off.

I guess I need to call them when I get a chance. I guess if Sony does nothing then an alternative would be to turn off DRC and use a receiver that supports deinterlacing and line doubling. (My receiver doesn't have this support.) Any other possible alternatives?
