Question about Sony Bravia XBR-Series KDL-46XBR4 46-Inch 1080p LCD HDTV

1 Answer

Portion of the screen is very dark, gets better after 20 minutes

When I turn on the TV, about 2/3 of the screen is black on the right side. As the TV warms up, the picture starts to get better, but with horizontal lines (jumping up and down). After 20 minutes or so, the image fills in and now looks fine. There is also one hairline vertical line on the right hand side, about half an inch from the edge.

SOURCE: A dark but transparent horizontal line has

Mine had the horizontal lines you are talking about. 1st check a test picture. Click on Menu, then Settings, then go to Product Support. From there click System Diagnosis and go to bottom and click on sample picture. If you see the same problem there, then you may want to research the possibility of installing a t-con board. You may want to try calling Sony 1st and have them walk you through the basic service repair items. I was very lucky and installed a new t-con board I purchased with all the other boards on Ebay. Good luck with solving your problem! Ron

SOURCE: Permanent Vertical Line on my Sony Bravia 46 inch LCD TV

What you're describing is usually the result of an improperly seated connector. With the power disconnected, open the tv and locate any connectors between the LCD screen and the driver circuit board. Unplug them, and reconnect it assuring it's properly and firmly seated. Be careful when handling these cables as they tend to be quite fragile... take your time.

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.

Testimonial: "Thanks very much for your response. I guess enough of us complained that they faced up to the fact that this is their "Toyota" and they'd best fix it"

SOURCE: 46 inch Sony flat panel lcd has vertical red and

If the screen works for a short while and then completely fails once the TV warms up you have a problem with the main unit video board or the LCD control logic board. Most often if the picture cuts out but audio continues to work the logic board is over heating and should be replaced. However if the picture cuts out and audio shuts off as well then its your video input board.

SOURCE: I have Sony kdl46w4100. It

I had a similar problem with my 42 in Philips LCD HDTV.



Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors. Many electronics companies were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you.

1. Have it fixed by a professional

2. Open your TV and find PSB. Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board.

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.


I have a tip/tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's called: Fixing the Philips Turns/shuts off on its own problem.


Hope this helps and Good luck.

That sounds like a faulty LCD panel tab. The only true fix is to replace the screen. This usually isn't cost effective.

When switched on the dark black covers 70% of the screen and after 20 minutes comes to normal. why, and what to do


Failing backlight inverter. This board lights the tv. The inverter is going out and the CCFL bulbs are slow to ignite, hence the light issue. You will need to open the tv and locate the backlight inverter. Found on the left or right side of the tv, looking down. Replace with the same serial # of the bad board and you will be up and running again!



Thank you,
