Hi Guys, Went out on this Sony projo yesterday, customer showed me receipts that she has had the STK4278`s changed twice in this set almost exactly one year apart, picture has the usual vertical bow and misconvergence. I checked my notes and have nothing on this set for repeat convergence problems, all the resistors check good, solder is good on bottom of board, no dark burnt areas on the board, The only thing I can see wrong is the price the shop in Tennessee charged her for the STK`s one year ago, $32.00 each, this seems a very low price for OEM Sony parts so they might be generics and there just not holding up???? Anybody got any tips or prior experience with this problem ? tia, Larry E Larry Eastman American TV & Electronics Crystal River, Fl. 34428 ----------------------------------------------------------------------------- Lost Password: http://www.tech-assist.org and select "Login Problems?".
