Samsung TV - Power on Problem - Capacitor Replacement
This is a video of a Samsung LCD TV - LN46A550 that stopped working about 4 months off warranty. I'm not an electrical engineer or a TV repairman. I'm actually a girl who has never soldered in my life. If I can do this, you can too!! I apologize in advance for all my "ums". I'm also NOT a professional speaker. :) Cheers!!

How does this tv work for you? Do you notice the 60 hz even though it says the cmr is 120..does it compare at all on fast moving images?
ReplyDeleteYou RULE! even if you're a girl! My 8 year Samsung just got this problem, time to get soldering!
ReplyDeletewow those caps were bad would have liked to have known there rating. good job but remember people clicking is the relay refusing to clamp due to power fault it can be from the sustain control board as well
ReplyDeletePretty good for a girl -- just kidding: that was totally awesome! I think that I am going to have to do this soon to our 40" Samsung, and your video will be my guide!
ReplyDeleteWe have the same problem with our SQ01 but because Samsung is aware of this "across the board" problem, a Samsung servicer is coming to the house to fix it for free. On the outside chance the service person doesn't show, I'm going to do it myself. Your video is excellent but you didn't show any of the soldering work. Exactly what did you have to solder?
ReplyDeleteVery nice job! I have the very same tv with similar problems. Will attempt a fix.... thanks to you.
ReplyDeleteIf a "girl" can do it.....maybe this guy has a chance, too.
Did you see those huge capacitors? Those things can hold a charge for hours after you unplug the tv leave it unplugged for at least 12-24 hours.
ReplyDeleteIf your in a hurry you can take a length of wire and short each side of the capacitors to a grounded piece of metal. Id refrain from shorting them out to a piece of metal on the board because you could fry other sensitive electronic parts that aren't as easy to test/replace. The center ground off of a 3 prong computer cord should work, ONLY THE CENTER
2:49 - I bet your Dad is proud of you. Good job girl!!
ReplyDeleteGeminitx1234, you are not a girl, you're a woman!
ReplyDeleteur voice is sexy
ReplyDeleteSo... i did this last week by myself too after watching this video. TV works now again. Thank you very much for everything! For all your replies to my questions and so on... :)
ReplyDeleteThey are capacitors, transistors are completely different.
ReplyDeleteNice video, kudos to doing something you've never done. But really, we can hear you are a girl, you don't have to say it in every freaking scene. Minus the ranting about being a girl and your not a expert, good video.
ReplyDeleteThanks for the video. Going to try this soon!
ReplyDeleteWell done. Don't think I'd have the balls to do this and I am a boy :-)
ReplyDeletegreat video, nice job showing how to fix this issue.
ReplyDeleteits a capacitor, according to google translate, german word for it is kondensator
ReplyDeleteGOOD ON YOU ,for having a go yourself at fixing this, personally i would feel physically sick at the thoughts of paying 400 dollars ,for someone to spend maybe an hour and $20 to fix it :)
ReplyDeletehow do i discharge everything?
ReplyDeleteThis is a great video. Be careful about unplugging and discharging all residual electrical charge before opening the TV. To those that complain about the undersized capacitors, I feel ya. However, the people making the TV probably got paid 2$ for the day and to the overseas manuf. co. that 2 bucks is a big deal. Want to fix that problem? Buy American, support American industry and understand that you may need to pay those workers a living wage to get the quality and workmanship. Just sayin'
ReplyDeleteah capacitor i know it now ;-) well but anyway thank you for this great video. Thumbs up!
ReplyDeleteThank you for the video. I'm going to try this by myself too. But what do you call these things you show at 7:10 ? "compessedor" ? I need to know it because I need the german word for it. I always thought they are called "transistors" ?!
ReplyDeleteNicely done. Bravo!
ReplyDeletedude, that's on old tube type TVs. those CRTs needed a high voltage to operate, these newer flat screens don't need that type of discharging time.
ReplyDeleteI am guessing here, but it seems that the ones that typically go bad are near the large heat sinks. Those are the large aluminum parts that have rectifiers screwed in to them. They are supposed to dissapate the heat generated by those rectifiers, and the caps are close enough, they're getting hot too. The other thought I had was to repalce all the caps that are rated at 10V, probably should have been 25 or more. Again, that's just a guess.
