Picture originally went black/sound off and status light blinked 7 times. The repair person replaced two IC regulators and said it didnt fix the issue. He took the board with him to further diagnose. He called and stated I need new high voltage transformer and it isn't available as part anymore but only available on a complete circuit board (the DZ board #A1302936A) for $300. I owe another $100 for diagnosing not including the board.
I called Sony and the board is available for $169 but they stated the high voltage or flashback transformer isnt part of that board. Now I am lost. Am I being taken for a ride by the repair man? Any help would be appreciated.

I have the same exact problem kv-34hs420. T.V. just went black out of the blue and stand-by light blinks 7 times. This really sucks. I have the extended warranty from Best Buy and they are coming out on May 16, 2008. Today is May 8 so if you can wait 8 days I will post the results so you have a better point of reference for your repair. 8 days no play-offs!!
Good Luck!!

I have the same problem. Sony recommended 3 repair shops. I was told it was the D board estimated repair cost $500 approx. I am dumping the TV and getting a 32" LCD for about the same cost.
