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.
Your LCD panel has failed, it will be cheaper to get a new set. If I have helped you please sign my guest book

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

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.

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"

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.

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.
