I don`t need voltages , i`m sure your power board is fine
Just a few questions
Do you still have sound ?
If you turn the tv off and on again repeatedly do you always get the sharp logo before the screen turns off ?
Never mind but i meant does it boot the same way indefinitely , , logo then off ?
I know what this is , please give me a minute to type this down
By the look of it I`m afraid that what your tv has is another case of defective LED strips and this is very common with LED backlit tv`s nowThose LED`s are supposed to last a zillion hours but they do not , they are failing all over the place and not only in LG
Here is a link to give you an idea what is needed ;
There is also a video on that page that shows you how its done so before you order anything watch it
Mind you they don`t have it in stock at this time , these guys can`t keep up with the demand but if you were to look into this yourself then you could sign up there to be notified when back in stock but i must say that this is not an easy job to do and you will have to be comfortable working with electronic circuits , here is a video that shows you how its done , not your model but the same job ;
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.comThis 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 .
Let me know if you have questions and if not for now then PLEASE DO TAKE THE TIME TO RATE (stars above and submit), it does not cost you anything more and does not close this post ,Also you can come back at any time without additional charges if you have further questions or need help and it gets this independent tech. paid for his time helping you .
Yes normally you should be able to see it
The dead give away here is the logo coming up then the screen shutting down
There are one or more defective led and when the driver board senses it then it shuts the whole thing down , this is very common now
I don`t have the specs or service manual for that board , suffice to say that it is not the problem
