Thank you Jingasharo for returning the answers to my questions. It was unnecessary for anyone to imply you are not trying to be helpful. You took the time to try to be as helpful as you could and for that I can only be appreciative. I wish you well in future projects. Be well.

Got it! Thank you Diah for letting me know. Have a wonderful holiday season and thank you for taking the time.

Hello Jingasharo, I realize you have been kind enough to respond to my inquiry but I wanted to ask another question. Did your TV repair have same two black lines as my tv and other OP? Second question is can you give a range for repair $$? Reason for asking is pretty good TV repair guy told me it’s 90% a defective display panel. I’ve seen over 20 of these same TV’s online in the States with same exact issue. I’m guessing this is a complex repair as this TV guy wanted nothing to do with it. Regardless thank you to all of you who took the time to respond. I will absolutely share. All the best!

Thank you Jingasharo for your reply. Appreciate your photo as this is the closest I’ve come to locating the issue. Thanks again and be well. I will follow up if I learn anything with more specificity.

Thank you so much for getting back regarding your issue! I really appreciate it. I have read the address boards are attached to the panel so I’m assuming entire panel replacement or replace defective chips? Thank you again for following up with photo, very helpful. Have a terrific holiday and be well.

Thank you for your feedback EazyBone! Have a wonderful Holiday!

Hello, I’m new to electronics and stumbled across this site and it looks full of knowledge. I’m looking to learn and eventually share information around electronic repairs.

Hello, I’m new to this forum. I literally had the exact same experience this week with my 2020 Sony Z8H 75 inch TV. I mean exact same screen as prior posts here. Mine went from showing the screen with the two black bars to the no screen with 5 red blinking lights. If I’ve broken forum rules by posting my apologies but would be super interested if Jingasharo feels comfortable sharing what the fix is? Thanks
