Blue light is blinking again. It says "starting up plasma"
TV Technician: Shahid, Technician replied 1 year ago

Just to confirm, is the blue light flashing 10 times, pauses and again blinks 10 times?

Customer reply replied 1 year ago
Starting up. Please wait. Plasma display
TV Technician: Shahid, Technician replied 1 year ago

I understand, please check the blue light on TV, does it blink 10 times as well as you mentioned in opening statement of question?
That blue light is presenting an error code and number of times of flashing will tell problem section in TV.

When I turn tv on now it says the above statement. Then blinks 12 times. Stops and blinks 12 again and repeats.
Customer reply replied 1 year ago
What you asked but 12 times.
TV Technician: Shahid, Technician replied 1 year ago

OK, thanks.

Working on 12 times error code, give me 5 minutes please.

Ask Your Own TV Question
TV Technician: Shahid, Technician replied 1 year ago

OK, the error code (flashing blue light 12 times) indicates communication error with D-Tuner mounted on main board, main controller chip isn't getting feedback signals from digital tuner box mounted on main board thus goes to protection mode and present error code of trouble. You would need to replace main board of TV to resolve the problem. If you are not comfortable working on it yourself then you may please use following link to get list of TV repair shops in area which will help to get repair quote...

I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue. I trust my input will help you out to make decision about this TV repair or invest that money on new replacement TV.
I hope these info will help. If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page.
Thank you.
