You know how to reset the tv to its factory setting, I think you are a technician. Second thing you can do is software update. Go to http://esupport.sony.com/US/perl/swu-list.pl?mdl=KDL42V4100&LOC=3#div_pos_30 . If it doesn’t work. Replace the Main board (UB board). Part # A-1547-086-A Cost approx $320.

Hi,

I am afraid I have some bad news for you, I honestly feel bad giving it to you because I know its not what you want to hear. Hopefully if you follow my advice you can get a good outcome here.

I believe there is about a 98% chance you have a bad LCD panel, without physically diagnosing the tv I cannot be 100% sure but I am very sure that you do have a bad LCD panel. The LCD panel, if you don't already know is the actual viewing surface for the television. The reason this is such bad news is that the part cost is over $1200, and labor is around $400 to have one installed. This is most likely more money than it would cost to purchase a new set today.

Now the only thing I can suggest to you is to call Sony and complain. I have seen many people get a positive result by working with sony, especially since the tv is only 3 months out of warranty. What you will need to do is first get a sony authorized service center to come out to your home (you can find one on sony's website) they will need to give you a written estimate with the parts and labor broken down. Once you have that paper you can call Sony and begin working with them to get the repair fully covered. I cannot guarantee you that they will fix it, but I have seen a lot of people call Sony and work their way up the ladder and end up with the repair being fully covered.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!
