Re: Classic 2008 Samsung LN52A580 Bad Caps
Hey ya'll thanks for your help. I ended up getting a whole pile of different capacitors, but I only replaced 3 that were blown.
Put it back together, fired it up, and it's been running fine for the last year.

Made the order. Total for all 8 caps including the SMD and 10v tester: $8.
I decided to forgo a solder sucker or wick, and will grind my soldering iron down to a finer tip. Guess I need to find some thinner solder, as well.Leave a comment:

That's what I suspected. Thanks for the clarification.
I wish I could understand better how to use the round capacitors to check or "bypass" the ceramic one. I'm a visual guy.
When this is all said and done I'll take lots of pictures to help future newbs like myself.Leave a comment:

Re: Classic 2008 Samsung LN52A580 Bad Caps
Sorry.
You gotta remember that you guys use some terminology that probably 99% of the population has no idea about. Very few people do electronics repairs, and even less have it as a "hobby". So bear with me.
I meant changing a Surface Mount Ceramic or Solid Chip Capacitor (a little block thing) to a PCB Mount Electrolytic Aluminum Capacitor.
The Surface Mount won't have holes like a PCB Mount, right? Because it sits "on top" of the board, versus going through it?Leave a comment:

Has anyone posted any walkthrough on how to switch the poly caps to electrolytic smd capacitors? Seems like quite a change.Leave a comment:

Re: Classic 2008 Samsung LN52A580 Bad Caps
Thanks for spelling it out for me. It sounds like same capacitance and voltage being same or higher than original are the best choice. It also looks like the ones I found on DigiKey are Panasonic FM-Series.
I assume temp doesn't matter too much?
What kind of capacitor is it?...Last edited by pollymath; 03-06-2017, 10:20 AM.Leave a comment:

Re: Classic 2008 Samsung LN52A580 Bad Caps
I'm curious why I should get the 100uf>10v caps? Or at least, why I might need to replace them if they aren't noticeably bulging?
Speaking of which, is there a buyers guide for replacing bad capacitors? I saw that [URL="http://www.shopjimmy.com/samsung-bn44-00200a-ip-361135a-power-supply-component-repair-kit.htm"]ShopJimmy has a repair kit for my power supply[/URL], but at $20 it includes quite a few things I don't need likes fuses and a circuit.
If I bought via DigiKey, I could save...Last edited by pollymath; 03-06-2017, 10:15 AM.Leave a comment:

Re: Classic 2008 Samsung LN52A580 Bad Caps
Wouldn't removing the C102 capacitor just keep it from functioning at all?
Sorry, despite rewiring numerous vintage motorcycles, I'm kinda dull when it comes to electronics stuff.
I did figure out to upload some pictures to a badcaps.net hosted album, though:
I'll try to collect some better pictures of the entire boards for reference purposes.Leave a comment:

2008 Samsung LN52A580 with Bad Caps and potential C102 issues -
Re: Classic 2008 Samsung LN52A580 Bad Caps
Bud, any walkthroughs or descriptions on how to do this?
When you guys say "lift the C102 to test", what does that mean?...Leave a comment:

Re: Classic 2008 Samsung LN52A580 Bad Caps
So should I still bother replacing the bulging/leaking 25v 820uF capacitors on the PCB? Or start with the C102 and work may way back?Leave a comment:

Classic 2008 Samsung LN52A580 Bad Caps
I've got all the classic signs of bad caps on my trash-picked 52" Samsung backlit LCD tv. I actually caught the previous owner throwing it away (gently), and he said it had been having trouble starting up.
I took it home, plugged it in, and the red LED just clicks on and off continuously.
Now, I'm not an electronics guy. I've wired cars and motorcycles, but little electronics are not my thing. That being said, a free 52" TV is hard to turn down, even if it does require some solder and a few hours.
Models specs are as follows:
