Sorry it’s covered as it’s mounted
TV Technician: Jack, Technician replied 5 months ago

How old is it approx. ?

What size ?

If you`re not going to work on it yourself then i can still give you an estimate with the info from those 2 questions but for part numbers and where to get them i would need that number

Looks like it is behind the universal base stand bracket

If you turn the tv off and back on again do you get a brief flash of light or perhaps the company logo on the screen before it goes dark ?
Is the screen just blank with some background light or completely dark like when the tv is off ?

OK then i typed down your answer while waiting for you to reply

A panasonic of that age will be a LCD/LED backlit tv and if the tv still turns on and have sound then there is more than a good chance there is a burnt led /defective strip that causes the shutdown of the whole screen

Those LED`s are supposed to last a zillion hours but they do not , they are failing all over the place and not only in panasonic but all led backlit tv , which is the only thing left on the market now anyway

Perhaps the new model have better systems and led strips but tv`s of 2 to 5 years are failing all over the place for this problem

Just to give you an idea of what this entails , take a look at this video , , not your model but the same job ;

https://youtu.be/qGk6Nx82SCA

If that is not your cup of tea so to speak then to have this repaired at home could cost you around $250 parts included and perhaps $50 less if you take it to the shop yourself .

If you need to find repair shops near you then look at the link below and enter your zip code ;
www.tvrepairpros.com
This will give you a list of NESDA member repair shops in your area.
This list may be limited though and you may find more by simply using the yellow pages or simply google "tv repairs" and the name of your town .
You could give a call to different shops in your area to get an idea of their rates , it pays to shop around but you can buy a new 42"+ for that money
