Toshiba DLP no picture 62HM84 4434ZA board problem

Hi , having this Toshiba DLP TV with a problem with the 4434ZA ballast power supply board that provide the power to the lamp.

R3 is open (1 K resistor).

Seems to be a feedback resistor.

Can I only replace it ? I saw on a few post that this is a common problem and maybe a bulletin has been done for this.
