Question about Sony KV-27S25 27" TV
And will sometimes catch for a min than back to flashing in and out

Most likely the flyback assembly, and or the horizontal output transistor failed. There is also a possiblity of some other faults that are putting the power supply in to the protect mode.
If there is a scan failure, it is possible that there is also some damage in the power supply.
The set will have to be serviced by a TV service tech.

Follow the instructions from the image provide and see if that works, if it does not work; you have a hardware failure in your TV. The hardware failure could be the HOT or flyback transformer.
Let me know if you need further assistance.

The 2 blinks usually mea an over current problem. Perhaps the most common cause of this is a shortde Horizontal Output Transistor (HOT). If you can solder, you should be able to repair this yourself. Realize that there are potentially dangerous high voltages present inside the set even when unplugged. Look for a 3-legged ransistor attached to a heatsink close to the flyback (part with large red wire coming out the top). The part will be marked C5438 or something similar. Post that marking here nad I'll confirm the entire part number.
Keep us posted.

I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.
If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.
I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.
Please let me know if I can be of further assistance.
