How old is your TV?

Also did your turn it off, or did it shout off by itself?

And does it get a lot of use?

Thank you

Thank you for that information.

This could be one of two things but both require service unfortunately.

This could be the power supply board or the back light but I suspect the power supply board as the fault on this one.

Its something you could replace your self with my assistance if you are handy and have some basic hand tools.

Let me know on that?

I can tell you the best place to get that board I will talk you though this its pretty easy to do.

But if not, you will need to have the TV serviced, Best Buy is very good with this, they send it out for the repair at a good price and they do very high quality repairs.

Or you can check for a small local home audio Video shop, as most of them now perform repairs either at your home or the shop.

I wish I had better news for you, I really do.

In any case, I will stick with you until this is complete,

Thanks, ***** ***** time for the LCD Backlight and its driver board or ballast as its called.

Please rate kindly.

What's the procedure for the backlight?
Expert:  Master Fix It replied 1 year ago.

Hi, you would remove the light and the ballast, as that is the best thing to do in this case because if you just change the lamp, the old ballasts seem to have trouble powering a new one due to the higher current draw on old components.

I think on that one, you need to desolder the back light, the ballast just is a plug in connector I believe.

But if you don;t have good soldering skills it would be best to have someone with experience do this one because its really easy to cause more damage to the board if you make a mistake.

Please remember to rate kindly so We can remain together, also its the only way I am credited for my time with you.
