    LG 37LC2D - Backlight, no pic or sound

    Hello,

    I'm completely new to the forums so please correct me if I do something wrong or post in the wrong location.

    So here's the situation:

    A week ago I found an LG 37LC2D-UD tv in the hallway next to the stairs, not having one I decided to take it thinking I might get lucky. After searching up the serial number I came across this forums and read up a lot of what other people experienced with the tv.

    At the time of posting this I'm currently visiting home so I can't add pictures until sunday evening. This is the first time I've ever done any electronic stuff so I'm kind of posting to see what I can do here.

    After stripping off the back and looking at the PSU, I noticed one bulging cap at C200, the pins are very close together and I've never soldered anything before so I'm kind of nervous about trying to fix it. Nonetheless I'm currently in financial distress so I haven't gotten the chance to order the repair parts. I was looking at this http://www.amazon.com/37LC2D-UD-CAPA.../dp/B00M1AJCRY in order to purchase the tools and the cap I would need to replace.

    I do not have a multimeter to test the other caps, nor do I know how to even test them if I did have one.

    Basically what I'm asking is, is it worth trying to fix this tv? I don't have one currently and I room in a 4 bedroom apartment so something in the living room would be nice.

    And since I'm not next to the PSU i think the cap was a 6V that was bulging. I apologize and will edit my post accordingly once I get back to my apartment.

    Thanks for any help you guys can give me. Good luck on your own endeavors!

    Anyone able to offer any insight to the situation? I'd like to come up on a $400 tv for the price of that amazon repair kit haha.

      I repaired one of these not long a go i managed to get a replacement power supply for about £15.00 so i opted for that route the kit you have listed does not seem too bad i wonder if you can email the seller and ask them what capacitor make/series is used i tend to use panasonic myself when i buy capacitors.

        So I received the package as of 30 minutes ago. I replaced the obvious bad cap (bulging) and then i proceeded to screw on the psu and test it. Upon turning it on the first time the tv worked. It said HDMI in the corner whereas before this point it didn't say anything. I was using the buttons on the side and couldn't get the volume or anything to pop up on the screen. So I turned it off and tried to the use the remote. Upon turning it on with the remote the light blinked 15 times and now I'm at the same point again where nothing is working.

        Now, what would you veterans do in this position as this is the first experienced I've had with anything of this sort of tasks.

        Is there a location someone could direct me to maybe look at replacement PSUs for the TV? As I'm sure that buying a replacement PSU will be cheaper than buying a new tv.

        Thanks for the help.

            I only replaced the one that was bulging. Should I replace all the capacitors with the new ones i've received? This is the first experience I've had soldering anything so I'm slightly worried I might mess something up. Is it worth doing before I try looking at a replacement PSU?

            Thanks again for the quick response I do really appreciate it. A tv would be much better than staring at my laptop trying to watch a tv show or movie.

              if you take your time i guess its worth trying just make sure you replace the capacitors with the same uf and voltage that you remove and make sure you get the polarity right one side has a line which is negitive (theres also a mark usually on the circuit board under the capacitor too) just check as you remove them once youve done a couple it will get easier. look on you tube too theres some good videos on soldering capactors etc.
