I do not agree with given info by previous expert that has no idea how tv works.
9 times red light blinking shows problem with sound output chip in tv, please check following things to fix the issue or pass it to local tv repairman if you have no electronics stuff fix experience.

/- 19V line is shorted on A and B boards
IC708 is defective on A board
PS701 or PS702 (both are fuses) is blown on A board

Hope these info will help you.
Thanks.

This indicates the power supply on this unit has failed, or something in the IC board of the actual TV. There is unfortunately no easy fix for this. You can try just unplugging the TV from the wall / power strip for at least 2-3 minutes, then plugging it back in, but chances are it will not fix the issue. You will either need to order a new power unit for the TV and install it yourself, or if you have never done anything like that, you will want to contact a local TV repair person.
Sorry about that, hope this helps!
