@chipotletv 4:17 Is this an INDUCTOR at the bottom end of your thumbnail??

My TEAC has a backlight problem after 20-30 seconds and this thing seems to be burned or something(The coil has popped out at the bottom).Could it be it causing the problem?Tnx

@sbartsa Hi there, Most likely, if thats the circuit that delivers the 24 v for the backlight inverter, If you still have problems let me know. Be safe!

Hey dude, I have a samsung lcd tv and I can turn it on and the backlight will come on and the turn on noise will sound but there won't be any picture. Recommendations?

Nice video, and if anyone's wondering whether or not to follow if for their own TV, do! It really is as easy as it looks; I'd never done any soldering before, and I've just replaced no fewer than eight blown capacitors on my TV (yet another LG), and it worked first time no problem. Thanks for posting!

nice video if you are teaching people to unscrew and screw in screws, you mentioned needing a de-soldering braid where did you use it in the video? I would think showing how to replace a cap on the board would be of more importance in a "How to repair" video than a demonstration of dissembling the unit. . . .

@chipotletv Hi,tnx for the quick answer.So i replaced all the caps but one(which i couldn't identify) but the problem persists.The gui at the store told me that probably it's not the inductor since they don't actually burn on the inside.My problem is that for a couple of minuits i have image but then goes out all of a sudden.So something is wrong but in the tablet it all looks good- so if i open and close the TV could this burn the malfunctioning item and show me the problem?Tnx
