Thanks every body! GGG i figured it out works same way in ps 2 tester, so reset. board no change, so i took board out of tester and examined very carefully both ps3/2 board's found toroid coil only 2 connections were soldered all the reset were not soldered at all !!!!!!!!!!!!!!!!!!!!! soldered all connections and now signal strength was perfect 10'S! i never had a bad ps3/2 board until now! guess there is a first time for everything!
again thanks all n GGG!
