Line, faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.

I am scraping out my tv all boards are good the tv played great just wanted a wall hanger if you need a part call me 270 589 8074

It is going to be a faulty light tunnel or a faulty DMD board. Both possibly require a complete light engine replacement. That repair requires a technician to do it.

Hi,
if you mean the left and right sides of screen, look for a button on remote might be labeled several things, like picture size, aspect etc.. the borders pop up when you go to a non high def channel. some chs put borders all around the picture in those cases you won't be able to get rid of those.

did u find any solution with the mixer? I have a similar problem. Channel 2 works great, Channel 1 is sending only the Left side, something like Mono instead of Stereo.

Check you assign buttons and bottom (three black square buttons) and play with them. It sounds as if you are not sending to that side. You should use mono cables into left and right. I set pan on left all the way left and right, all the way right. Hope this helps.

try turning the channel up or down with the tv remote to input 1 or 2 depending on which one is being used for the dvd player. tv should use input 1. dvd should be on input 2.
when turning the channel set it to show the dvd screen, then go up 1. if it doesn't show, return and go down 1.

You need a special 1/8" cord for video output. For example the standard 1/8" cord has 2 black rings on the 1/8 plug, each ring is a channel one for left side and one for right side. You need an 1/8 cable that has 3 rings on the plug, 1 for video, 2 for Left and right audio channels. It dosen't have to be an IPOD brand cable it just needs the 3 black rings.

Good Luck

This is definitely a broken LCD display screen. Since it's out of warranty you'll have to pay to have Sony repair it or just buy a new one. Bummer. Sorry to hear that you're having this trouble.

It's definitely not convergence. Sounds like more of a problem in the horizontal section.
