Ok, I repaired this issue before, the led bulbs in your led screen are bad 6 blinking lights means the led strip has dead led diodes and the televisions mainboard tells the tv to go into shutdown mode. You can buy the led strip on ebay or aliexpress. Sony dropped the ball on these models the led strips fail consistently. I built a suction jig with 6 suction pads using aluminum bars I bought from home depot to lift the led display module . This repair is not easy but it can be done. If you need help with how to remove the led display I can put a tutorial together I advise you buy the led strips not the led bulbs. You can buy a tv led strip tester on ebay to test which led strip is defective.

It can be done, I have done it, I can’t find the actual glass anywhere for purchase, heat and air suction vacuum is the answer.

Even if the led strips light up, I noticed the Sony bravia from recent 2017 and up ha e some sort of check feature on the main board. It searches for correct voltage in the led strip and if the voltage is off higher or lower it shuts down, you need to change the led strip this will solve you problem but first you should buy the power supply tcon and mainboard first, If that doesn't solve the issue you should replace the led strips those led strips are always going bad. Additionally please buy your boards from shopjimmy.com not ebay. Ebay boards cant be trusted the sellers are not pros they will sell a board without knowing if it works or not or if you will buy a board from eBay buy a board from a power seller with 100% feedback.
