For Sony Model KF-60WE610, KF-50WE610, and KF-42WE610, the Diagnostic Code of power light indicator flashing 6 times green, then flashing 6 times red (6 red etc), means you need to replace part number A-1302-272A G1 BOARD, COMPLETE. See Sony Service Manual, 4. Chasis-1 at part Ref no. 103. The Power Board sits vertically in two slots on the left side of the electronics board. 4 wire connectors to remove when replacing. This component fits all 3 KF models listed above.

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!

This sounds like an issue with the optical block assembly. Sony had a problem with this part in a lot of the KF-series television.

They extended the warranty of optical blocks in the KF-42WE620, which doesn't help you but from what your saying this sounds like the issue.

sounds like you need a new light bulb
