Replace the Main board the only possibiity http://www.shopjimmy.com/sony-a-1547-090-a-bu-board.htm
Is it possible for me to install the A 1547-090- ABU Board in my TV without taking it to a repair shop?
You advised me to get an A 1547-090- ABU Board for my Sony TV. Can I install this board myself or will I have to have repairman install the board?

I just install the A 1547-090- ABU Board as you suggested. Everything seemed to go together correctly, but when I plugged in the TV the Green Power light initially came for a few seconds then the TV jumps to Standby mod. What is going on? Did I not get one of the plugs on the board in solid or correctly?
I double checked the connections on my A1547-090-ABU board as you suggested last night. Every connection looked good. The Standby Light on the display still comes on. What is the display saying when the Standby Light is on? The system acts like it is not accepting the new board. Is there something that needs to be done for the system to recognize the new board? What is my next step? Before I installed the new board I had both a picture and a sound. Now neither come on, only the Standby Light.
One thing I forgot. I unplugged everything from the TV. When I turn on the power the Standby Display Light still comes on and it can not be shut down. When I press the manual Power Off button nothing happens. The Standby Light just keeps blinking.
I'll tell you the story that sounds unbelievable. I put the old board back in place. The TV took off working just like new. The sound control is back on screen and there are no more lines in the TV.
Now I need to see if I can get my money back on the bad board.
Very pleased with your help.
