Hello [Sir/Ms], My name is XXXXX XXXXX Thank you for posting your question on Just Answer! I will be happy to help you with this problem

Count the LED blinking pattern before it pauses and repeats?

Can I have your make and model,,

on the rear of the TV

first would like for you to pull the power to all devices from the wall outlets for 90secs,,cable box,, satellite,, surge protector let me know if it works

do you have the tools,, voltage meter and skills to repair yourself? or just want a estimate



Customer: replied 3 years ago.
The TV is a Panasonic Vierra TC-P50S1. Unfortunately we unplugged all cables, including the power supply, before we knew to count the pattern. After unplugging everything and plugging the power supply back into the outlet, the TV no longer does anything. I do have a Digisnap Voltage meter. I think it's an antique. I do not know how to use it or if it even works, but I do have the instruction booklet.
Expert:  ricke1973 replied 3 years ago.

well if its totally dead,, this is a strong indication of the power supply being bad,, check the fuse and if its good then the power supply should be changed,,

let me know if there is anything else I can do for you!

If you have more questions please ask if not satisfied!

Only accept an answer when you are totally satisfied and willing to leave positive feedback. If I have answered your questions and met your needs even if the tv is repaired now or needs to go to the shop then please press the "accept" button. you can always reply back to me.

I got the light to start flashing again. TEN flashes. How do I check the fuse?
Expert:  ricke1973 replied 3 years ago.
10 flashes isnt the fuse,, give me some time to down load this manual
Customer: replied 3 years ago.

'The HDMI1 & HDMI2 inputs (at the rear) unlike the HDMI3 input do not have the equalizer/buffer circuit between the HDMI input and the HDMI receiver. They are dedicated HDMI ports for Audio/Video components (Blu-ray, Satellite boxes, Cable boxes, PVR). Without the equalizer/buffer circuit, the tv will not display picture and/or sound.

'If the PC cable is sending the 3.3v typical of pc connections, the tv may shut down and go into this 10 blinking pattern. For now, only HDMI 3 is recommended for PC connections, which does have the equalizer/buffer circuit.'

I unplugged the power supply and plugged the HDMI from Direct TV in to HDMI1. Now the TV won't do anything again.

ok do you need any more help friend
Customer: replied 3 years ago.
Yes, as a matter of fact, I do. I just installed the new power board I bought. Still having the same issue. Ten blinking lights. No TV.
Expert:  ricke1973 replied 3 years ago.
i apologize i never told you to replace the power board,, i just read all the threads we covered the power board was only mentioned when you weren't sure about the blink code,, after you were certain of the blink code i mentioned the A board not the power,,sorry for the confusion but its in all of our threads

Yes. I replaced the A Board per your first suggestion. Then a different expert answered in a different question to replace the power board. So, since it was still cheaper than buying a new TV and you had mentioned that first in our initial exchange, I replaced the P Board.

 

Sorry for the confusion. Just want my TV back :(

 

I buckled and took it to a repair company. I just hope they barter the price down in exchange for some new parts ...

 

Thanks for your time. I understand it must be hard diagnosing an issue without physically seeing the TV. I appreciate the fact you shared your knowledge with me and apologize if I seemed ungrateful.
