    Lg 32ln530b-ua

    I was watching this led tv and the screen went black. I get sound and everything but no picture. I did the flash light test and see that I do have a picture on the screen. From reading things I think it is the power supply board or the led driver board. (Correct me if I am wrong or if it might be something else.) If it is one of those two things how do I know which one? I also read some power supply boards have that led driver board built in. Anyway I can tell if it is with this model.

    I am not really sure what to replace.

    If anyone does know what parts I need to replace can they link them as well. ( I am going to borrow one from my friend, so what and how do I test this stuff. I have no with electronic boards and what not.)

    Just an fiy, I do not have a volt meter so I am not able to test anything.

    Thanks again everyone.

    The power supply board number is EAX64905001 rev 3.0 4/18/2013 version (2.7)

    looks like its built into your power board, thats the one I'd go with, since like you said, you have no testing equip. looks like theres a couple different ones for these, I would call and make sure it fits your panel # and serial #, and to double check that it coulds be the board you need, http://www.shopjimmy.com/catalogsear...Lg+32ln530b-ua

      Just curious based on what I said do you think it is def. the power supply board with the led driver or do you think it could be something else? If i was able to to get a meter what else would I test?

      Thanks again for your reply.

        I would be inclined to waste $5 on a meter in case the led strings are shorted/open

          I am going to borrow one from my friend. How would I test that? I really dont have any experience doing any of this.

            First get the meter find the model download an instruction book if your friend doesnt have one and learn how to use the meter.
