Samsung - Capacitor Replacement?

[Tx Redneck]

not sure about the tv, but I'm most def. "through the hole style"

god bless.

Not surprising...

Right... I mentioned that. They are no longer replacing the capacitors for free; instead they are now only covering the cost of parts. Labor charges are to be picked up by the consumer. Total BS.

Okay guys, the cheapass in me is coming out. I bought the ebay kit. Wish me luck.

What was the results here? I have never soldered anything before, but I may have to try this on my tv.

It's pretty easy man. I've repaired 2 nice ass Samsungs in the past year just replacing bad caps. There is an instructional video on Youtube if you do a search. I got a 55" 8000 series 3D Samsung that wouldn't turn on from a client and just fixed it today. TV is only 3 years old and was stupid expensive ($3,000) when it was new.

Basically, you open the board, find the bad caps, unsolder it and solder it back on? I am assuming the whole board has to go out, right?

Yessir. PSB should have 3 screws and 2-3 ribbon type connections that will have to be unplugged. Lift board out and find a nice clean, static free area to work. Also be careful not to be wearing socks on carpet etc etc while handling the board. The caps are the pass-through kind so you'll need to heat up the back side of the 2 solder joints where the bad cap is mounted. Just pull gently while heating until it slides out. Slide new cap in, bend over the contacts (It matters which way it goes. [+ or -] should be labeled next to each hole on the board. Clip off the excess with a pair of side cutters and solder the new cap into place. Easy peasy. I'd take down the ratings and take pictures of the bad caps and run up to frys and grab replacements. It doesn't hurt to use a beefier capacitor either...as that's why the old ones failed.

Another option is to get the model number off of the PSB and just order a whole new one from www.shopjimmy.com. Last one I priced was only $85 shipped. Simple swap at that point. Depends on how much your time is worth really.

Yep, been there done that twice! 50" Samsung Plasma! The second time after I fixed it I just sold the damn thing. The first time it was the capacitor, the TV would blink and I could hear the relay click but it didn't fire up. The second time the whole power board went out - no click, no light, acted as if it was not plugged in. Here is my suggestion. Fix the TV and immediately sell it. I sold mine a few years ago for $300 If I remember correctly.

My past experience was with a Mitsubishi rear projection (back in the day when these cost a fortune) that had one of the Sanyo convergence chips go out. I painstakingly disassembled the whole TV and motherboard, unsoldered the convergence chip, soldered in a new one, installed a better heatsink, etc. and it went out about a year later. Basically my experience has been a bad design is a bad design, it's all band aids. I replaced the plasma with an LG LCD and it's been perfectly fine for about 5 years. The heat and power consumption of a plasma is just inherently bad for reliability.

well, i was going to use this opportunity to learn to solder, but if I screw it up I can always replace the whole board.

I ordered a capacitor 'kit' off of ebay for about $15. The kit was specific to the model number of the TV.

The capacitors in the kit were completely wrong.

So I said to hell with it, and just opened up the TV to figure out which ones were popped. I removed them, and went down to Radio Shack. I spent about three bucks on capacitors, and maybe an hour installing them and testing the TV. Been working like a champ ever since.
