Hello,

All lasma an lcd ts have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times reseating the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them, but it is very easy to wreck em.
Good luck.

Replace the video board, if you can find one. Letting it cool down will not help any.

This sounds like your convergence correction amplifiers have malfunctioned. These Integrated Circuits often burn out after a few years (STK392-110) they can be replaced with a higher version (STK392-150) However it is important to have the biasing circuitry checked to make sure nothing has burnt out as a result of the ICs malfunctioning. If you have a background in electronics you can repair this problem with very little effort, however if you do not have a background in electronics, I would suggest that you have your TV serviced by a qualified TV technician.

 

I hope this helps,

 

Thank you,

Go to the Sony Web support site. If your TV is one of the models listed with the blue dot problem (there are pictures of what the screen looks like with this problem)on the site, Sony is now saying that they will cover the cost of the part and the repair. We did what I'm suggesting and are having our part put in today. Sony decided this was their responsibility for some models of their LCD big screen HD TVs in June of this year. We were contemplating an estimated repair bill of over $1000 until we found out they were taking responsibility for this problem. Good luck, I'm not a truly techy person, but hope I have pointed you in the right direction. We have been living with blue people, etc. for about a year now, feeling angry about spending so much for a TV and it going bad so quickly. Hope this spares you that. You have only so much time to take advantage of this repair offer...
