SOURCE: Sony LCD Problem...

My t.v. just went out as well...how convenient because my warrenty just went out a couple weeks ago. From what I have heard from many different repair people that the problem is with the power supply board. Since I also bought the tv from sears here is my plan. I puchased the new board through sony which is only $150. I am going to swap it out with the old one and pray for the best. I have talked to sears about getting the buyer protection for the tv after a year after i purchased it and they will charge you a higher price for the warranty as long as the tv is still functioning. If all goes well with the repair i will get sears on the phone instantly because a service guy has to come out and verify that it functions properly.

SOURCE: i have a sony 40 inches bravia flat screen hd and

Could be the decoder:

1. unplug the TV ans wait a few mins.
2. If you have digital cable box or dish tuner reboot those as well (likely your issue)

What you have is artifacting what that means is tiling garbiling and freezing this happends when the data in the digital stream just stopped hence Frozen.

Try those things rule out your cable tv box first or your sat box, if this is OTA over the air your antenna.

1. Try DVD's if it happends during a DVD you do have a decoder issue if it does not you need to talk to your cable tv or sat operator.

So you got 3 possiabilites here 1. the worse Decoder, 2 cable company or satalite provider, 3 your antenna is in the wroung position.

I sure this will help.

Try this: got to www.sony.com mouse over "support" then click on "drivers/software" enter your model #(s) and then you can check for firmware updates, the symptoms that you list, unfortunently are somewhat common when connected via HDMI cables.
Check for updates on both product that you list.
