Sony Wega 36 inch code 4 repair suggestions

I have a 36 Wega TV KV36XBR450 TV that flashes code #4 which means no vert. deflection.  The recommended fix was  check IC509 and Q1505 but which board and where is a good place to get parts?

Your problem is most likely

Your problem is most likely the vertical output IC located on the "D" board in this TV set. The IC number is IC5004 and the part number is STV9379. The part is available HERE If you do not have the soldering experience or if you do not have the TV repair experience, play it safe and call out a pro to assist you in this repair.  Good Luck and let us know how this turns out for you.

Larry, for your experience, what is the approx. cost to have the 4 blinks issue on a sony xv36xbr450.  The TV set is about 4 years old.

 Thanks,

You will need to get the

You will need to get the service manual and check the voltages on the Ic as when the chip went bad, it could have taken out the power supply source for this circuit.

Hey Guys,

Hey Guys,

Well I replaced the IC but that didn't fix it, however, I did start taking some voltage measurements and will checking the +15V on the cable connecting to the A Board and in doing so it started working which leads me to believe it is a bad solder joint.  Now 3months later the problem is back so I resolder the connection point for the cable but that did not fix it this time.  I have +15V but that is the farthest I have gone at this point.  Care to point me in any more directions?

There is an obvious bad

There is an obvious bad solder connection somewhere on the board. Maybe a tiny crack in the board.
