Re: Sony Bravia KDL-52W5150 - Are These Symptoms Of A Bad T-Con?

As a follow up, I ended up following the procedure here ([url]http://www.avsforum.com/t/1173106/kdl-xbr4-half-the-screen-dark-with-slow-pixel-refresh-all-inputs[/url]) to put a bumper in the frame to put some pressure on the top left most tab on the TV. This has corrected the blur and other issues. I didn't have to replace either of the boards, so this $2 fix was pretty sweet. If for some reason in the future this fix fails, I'll let you know how long it lasted Re: Sony Bravia KDL-52W5150 - Are These Symptoms Of

My TV's issue has morphed now. It now on a cold startup has a tunnel / ring hazing effect. In the center of the screen the refresh rate seems normal and motion doesn't blur the image, however around sides and edges of the screen it has a dark blur and images update very slowly. If I turn if off and on it initially corrects nothing, the same behavior is exhibited when it turns back on. However, after the TV has been running in this blurry tunnel state for a good half hour turning off and on the TV corrects the issue...

I'm finding that it happens a lot when the TV has been off for a while when it first starts up. It seems like once it has been on for a while, usually after a few restarts, then it seems to go without issue.

Ex. Turn it on, problem starts within the first minute or two
Restart and a few minutes later it will happen again, restart
5 or 10 minutes later it might happen again, restart
then it might run for hours and not happen again till after the TV is off and idle for an extended period...

Okay I have captured an albeit lower quality video. Sorry about the bouncing around I was switching remotes a few times. And some pictures.

As you can see its really similar to the OP. Is there any way to find out if it were the t-con board or the DC power?Re: Sony Bravia KDL-52W5150 - Are These Symptoms

Re: Sony Bravia KDL-52W5150 - Are These Symptoms Of A Bad T-Con?

I'm having the exact problem as in the first post. Occasionally (might be as few as every other or third day and as often as every few minutes) the screen will either start up or start going into that bad picture. Its essentially the dark lines rotating horizontally across the screen (includes over menu screens and title/info screens) with a brighter area in the lower left corner. When this condition happens i'm also getting a buzz/ higher pitched noise constantly.

I'm really interested to see what...
