Story:
Coupla weeks ago, my wife started complaining that our TV was doing a lot of clicking before it turned on. Sometimes, it would click for 30 seconds or so before it'd finally come on. This is a 46" Samsung LCD that we got for Christmas a little over two years ago (love it, BTW).
Got to digging around on the web today, and found that the problem is somewhat common. Remember the "bulging capacitor" problem that plagued computer motherboards a couple years ago? Seems some of those caps made it into the power supplies of Samsung TV's. When they start to go, the power relays start clicking and eventually the power circuit fails.
"Borrowed" a couple caps from the E-Lab at work (which has been dormant since the last layoff :cry: ) and after an hour or so (mostly screwdriver time), had the problem fixed.
What amazes me, though, is the number of folks who seem willing to tackle something like this with no real electronics background at all:
not very tech savvy, my husband tried to desolder the old capacitors but wasn't having any luck, no experience soldering. so took it to electronic repair shop to have the capacitors changed. the guy said it was soldered with silver and sealed (whatever that means). anyway he changed the capacitors (for free! just asked me to make donation to shriners childrens hospital).
Just wanted to add my thanks to the resident experts who offered detailed direction. Was able to fix my TV for $9.42.
Was afraid to try this till my stepson called and said the magic words ......... "I solder". Only took us about 35 minutes!!!
I found out the problem was just two simple caps on my power supply that were bulged out just enough to tell. (CM852 & CM853) Im lucky theres a liquidation wharehouse not far from my house that sells brand new caps for 15 CENTS!!! Thats right I couldnt believe it either, that is until I got them home and did the 20 minute job of replacing them. They were easy to replace as I have a little solder experience and I already had the right tools. The tv powered right on with NO CLICKING for the first time in months!!! Total cost of job: 30 CENTS!!! And 20 minutes of my time.
2. Went to Radio Shack and bought 2 1000uf, 35Volt capacitors (See Picture 7) Cost: $1.59 each plus tax
3. Bought a cheap 5pc soldering iron and kit, including 60/40 rosin core solder Cost: $7.99 plus tax
Kinda floors me that a lotta folks with no electronical experience and have never soldered before would dig into a TV that cost them $3,000.
