Thank you for posting this video and information. This fixed my Sony Bravia 52Z5100 perfectly. I ordered the same BU board you used for yours from MAT electronics and it was the same one i needed. this saved me a lot of money!

Which board was it and where did you order it from? Thank you

my brand new bravia starts up with a black screen which i can get rid of by unplugging the tv and restarting, What is the problem ?

I called Mat electronics. We had trouble figuring out the part number over the phone. Do you happen to remember the part number or any part of it? Thanks!

Where did you find the replacement board?
