SOURCE: 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.

SOURCE: Picture messed up for a while when first turned on, then better

I just had the national service tech tell us the LCD panel needs to be replace. Just under $2000 to replace it. I bought my TV in Dec of 07. Called Sony and the TV has 1 year warranty. They are going to "review" my case and let me know in 24-48 hours.

If the problem is with the LCD display unit, Sony is now extending the warranty on the LCD display and will fix the problem for free through September 30, 2012. See: http://esupport.sony.com/US/perl/news-item.pl?news_id=378&mdl=KDL46XBR4 Call their customer service number and they will give you a case number. Then call one of their authorized service centers and they will fix it free, in home.

@circuitworld: You claim in your profile that you repair plasma and LCD TV's, but you just told someone with an LCD to replace the convergence IC's and linear buffers. First off, convergence IC's are in rear projection TV's not LCD's, and the buffer boards are in plasma's, again, not in LCD's

@gardenwc: Typically what you are experiencing is a bad video controller or an actual faulty panel, the latter of which is not cost effective to replace.

Worth a look at above, Hmmm??

Above is your service and repair manual for download.

What is happening is there is an internal "Fault" that is causing the Protection Circuitry , to detect the problem, and attempt to shut down the set. When we keep restarting the set, it may work briefly again, because as soon as it shuts down, the "Faulty" component(s) cool down?, and the "Fault" ostensibly "Clears" so the PSU starts up again, only for the component(s) to heat up, whatever, again and fail, so it shuts down, and if left unattended, this would continue on until the part eventually failed. Any fault that involves the power supply is usually quite serious, and needs a professional, usually, unless one is familiar with servicing current day, televisions.

my professional recommendation, you should get a "Quote" for repair, from, an, Approved Service Center. Now, this point is very important for a good result, Always contact, their "Local" or a, "Head Office" Sony, in your case. Ask them, for a referral to an authorised servicing center, where you ask for a "Quote". Now, when you get the information you want, then you can decide as to repair of replacement.

The reason we want an approved agent, is that way, all the engineers are trained on their own brand sets, they have seen almost all faults, and will get the job done quicker, and for less cost, and usually have parts on hand, also sometimes, there has been a service bulletin in issued and the repair may be subsided or even free. There are many, many, many reasons that display this symptom, one must work through the troubleshooting steps to isolate and identify, the Cause and repair that and any damage done.

Can this be fixed ? what is the problem?


What your describing sounds very much like a video board issue some part is not working properly until it warms up. Eventually it will most likely need to be replaced, If you are not sure what board or part is bad, in the long run it might be a better idea to just replace the TV.
