Have TV Questions? Ask a TV Technician
Hello there and welcome to Just Answer. My name is ***** ***** I will be assisting you today. I am an engineer with over 30 years of electrical and electronic training, repair and installation experience. I will try and answer your question accurately and precisely so that we can get you on your way.
I need to gather some more information from you in order to help.
Any chance I can get the model number of the TV? Panasonic made a huge number of different models over the years.It will be on the back, and also on your user manual if you have that available.
Ok, understood. Hold on please.
This set has a 10 blink and a 12 blink code but not 11. Are you confident that it is actually 11 blinks?
11 on some sets is the fans. Let me look again at the manual.
Ok, if you look at the back of your TV, near the top will be three fans spaced equally across the chassis of the TV. One or more is not turning. We need to figure out which one. Once you have done that, you can buy the fan and replace it. You can buy them on AMAZON for under $17 each.
Do you need help in determining which fan it is? You can sometimes view them through the rear but more often than not, the rear cover has to come off.
Let me know.
Yes. There will be plenty of screws. Some of them may be different lengths so as you take them out, place them on a table in the same position as they came out.
I was looking at a VT20 manual, not a VT25. 11 blinks is definitely fans. CLICK HERE for their location.
If any of them are slower, caused by dust, pet hair etc. that will also trigger an 11 blink code. In other words, they don't have to be fullly stopped.
For how long does the TV stay powered up before it trips out?
No. Not on this set. No filters. You definitely have one or more fans that are slower than they should be. They each have a tach wire that reports back to the A board. If the fans rotate slower than they should, the set shuts down for protection.
I would remove the back and then examine each fan. With the set off, see how easily each one spins. If there is the slightest resistance, that's your culprit.
How old is the TV?
This is quite an easy job. You only need a Philips screwdriver to remove the back of the set.If that is not something you can do, you are looking at a repair bill in the $150-$200 range just to change a $16 fan.
The TV has to be 3-4 years old, likely out of any warranty.
Ok, then the only other reason for an 11 blink is a bad diagnosis by the A board. Not likely.In my experience, change out the fans and you will be fine.
You can buy them on AMAZON for under $17 each.
Hold on, the link didn't copy. It's earlier on in our conversation.
>>>CLICK HERE<<< for the link.
I will be here even after you rate the service today. The dialog will not close so if you get the fans and need more help, we can continue.
This dialog does not close. You would reply as you have been doing.The 11 blink code is a very simple one. Replacing the fans will fix the problem.
Have a wonderful Sunday.
If that is all we have for today, please take a moment to rate my service. As previously mentioned, it does not close our dialog.
Thanks very much.
Hi, did you get your fans yet?
Wow, those are basic computer fans. Why on earth would the shipping for a 1/2kg package be $150??
And of course I am not familiar with your expertise with a screwdriver but this is not a hard job. You are going to end up paying more than a new TV to replace a fan.
Hi again. I notice that you have still not rated my service. It is much appreciated and it is the only way the experts like me are rewarded for our time with a percentage of your payment.Thank you very much.Steve
Hi. It's been a couple of weeks since we chatted. Did you get your fans?
