Back in a flash..well its either 12 or 13. Goes like this:
--power on..screen lights..HDMI shows up
--screen goes black...power light begins to blink
--"blinks" 12 times...but ends and pauses while lit
--starts another cycle
Customer reply replied 1 year ago
Looked again...think it is most likely 12 blinks.
TV Technician: Anthony_Infotech, Technician replied 1 year ago

I am afraid its one of those things you have to be sure about otherwise the diagnosis will be wrong.......

Then make it 12.
TV Technician: Anthony_Infotech, Technician replied 1 year ago

That blink code is a tuner supply issue the supply volts is going bad at the tuner so realistically a board within the set will need to be replaced, if you think you can do this work yourself please let me know I will provide all the necessary info for you to do that.

If you are not comfortable with that then yu will need a tech www.tvrepairpros.com will locate a tech in your area

Please let me know if you can do this or need more help thank you

If the work does not require specialized gear, I might be able to handle it. Please provide info on doing the job. Any notion of tech cost for such a job?
TV Technician: Anthony_Infotech, Technician replied 1 year ago

You may need to be able to use and have a volt-ohm meter

Also if you have got the blink code wrong then it will lead to wrong work being carried out

I have a meter. I am pretty sure on the blink number.
TV Technician: Anthony_Infotech, Technician replied 1 year ago

Sorry you do NEED to be sure on the blink code otherwise I am going to dedicate a lot of work if you are not correct and I can tell you off the bat that a 12 blink code is rare usually its 11 or 10

Customer reply replied 1 year ago
As I said, it is 12 or 13...there are 12 distinct blinks and one more that holds steady to start the new cycle. How should I count that ? For sure its not 10 or 11.
TV Technician: Anthony_Infotech, Technician replied 1 year ago

Its the blinking ones you need to know the stop light is just indicating the next phase of blinks thanks so it is 12
