Question about Sony KP-51HW40 51" Rear Projection Television
I have replaced a shorted bad G-Board with a new one from Sony parts and now TV gives 6 blinks. Any Ideas to check for?
Most problably the flyback and the horizontal transistor is shorted out you will need a tech to make some tests and determine if they need to be replaced

Set screen voltages. To get to the adjustment board, take the front speaker grill off (two screws at the bottom left and right) and set it aside. No need to disconnect any wires. Then remove the plywood board with 4 screws that exposes the screen/focus adjustments. The top 3 adjustments are for focus, and you need not mess with these. The bottom 3 adjustments are for Red/Blue/Green screen voltage rough adjustments. My screen showed red lines, so I had to turn the bottom right adjustment with a philips head screwdriver just slightly until the red gun retrace lines where no longer visible.
Hope This Helps
