All of a sudden my Panasonic Viera TH-C46FD18 TV won't show

Customer Question

All of a sudden my Panasonic Viera TH-C46FD18 TV won't show a picture. The power light blinks 13 times. It won't show a menu or anything. I don't have an original remote so I don't know if there is a way to do a reboot using the keys on the unit.

Thanks , a few questions coming up ;

Expert:  Jack replied 1 year ago.

Did it quit while watching it or simply would not come on today ?
Any electrical storm or power blackout in your area prior to this ?

Customer: replied 1 year ago.
I was watching earlier during the day. Left for about 30 minutes and then it wouldn't come back on.

O.k then before I show you what that 13 blinks code is , here is something for you to try ;
Unplug the TV's power cord and hold the power button directly on the tv ,keep holding it for 20 secs or so then let the tv sit unplugged for a couple of minutes before you try it again.
Although i do not expect much out of this procedure , it has to be done to confirm that this problem can be cleared or not with a reset.
If that does not do it then we are looking at internal problems with the tv.

let me know how that goes.

If that reset does not it then click the link below and you will see a picture I took from the service manual about that 13 blinks code;

The " A " board part #TNPH0721APS for this tv is the main board and while waiting for your reply I took a look and it does seem to be difficult to find "in stock" at a reasonable price .

The suppliers I found are asking $400 + except for one on ebay at $115 if you are interested , here is that link ;

If that is not your cup of tea so to speak then to have this repaired at home could cost you around $300 parts included and perhaps $50 less if you take it to the shop yourself .

If i may be frank , considering the age of the tv and the fact that you can get a new 50" plasma tv with all the bells and whistles for around or less than $500 ,I would think twice before investing that kind of money into this one.

If you need to find repair shops near you then look at the links below and enter your zip code ;

Or this one;

This will give you a list of repair shops in your area.
You could give a call to different shops in your area to get an idea of their rates , it pays to shop around.
