This manual may additionally help you with any emblem of liquid crystal display as terrible capacitors are very well-known in contemporary electronics. the old saying, "They positive do not make 'em like that anymore." nicely, they do not, and i for one suppose this is very intentional. these groups sell at razor thin income margins and they need you to upgrade every few years.
well these days, we win! With only a little little bit of attempt, very little talent, and only a few bucks, you may be looking tv in approximately an hour.
tools wished
restore samsung tv
you will most effective need four items for this restore:
• phillips screwdriver
• pliers
• wire cutters
• soldering iron (and maybe some solder)
want a soldering iron? No trouble. they're reasonably-priced and easy to use.
I extraordinarily endorse the J&L 60 Watts Soldering Iron. it's inexpensive, however has enough wattage to quickly melt solder.
in case you're looking for a better first-rate soldering iron, you can additionally attempt the Weller SP40LK 40 Watt Soldering Iron kit. Like something else, you get what you pay for, so in case you need to apply higher equipment for your highly-priced television, it can in no way harm to spend some extra dollars.
The TEKTON 7266 30-Watt Soldering Iron is less expensive but will work. With its lower wattage, make certain to permit the iron completely warmth up and make sure to permit the iron to absolutely melt the solder! most mistakes in electronic repair are from forcing additives in/out of non-molten solder.
ultimately, you can also recognize the solder iron base and holder on the Stahl gear SSVT Variable Temperature Soldering Station. It offers a secure a comfy region in your iron at the same time as heating up.
Get your replacement capacitors now for the quickest repair.
This Samsung repair package has all doubtlessly awful capacitors, solder, and other components to make this restore quick and easy.
got everything you want? Time to dig in!
Step 1: eliminate Stand
smasung clicking
After unplugging the entirety at the tv, you may need to remove the stand. if your tv changed into wall established you may want to dispose of the television from the wall, and take away the mounting bracket from the back of the television.
pink arrows: eliminate those 4 screws to get rid of stand from tv.
Blue arrows: do away with these 4 screws to remove a wall mount (not shown) out of your tv.
The tv sits on pinnacle and inside the stand, so it wont simply flop over whilst you do away with the stand screws, but it is always more secure to have a chum keep the television upright as you eliminate the screws from the stand. Then each of you take hold of a facet and thoroughly lay it flat on a carpeted floor.
Step 2: take away All Screws That attached the returned Casing of the television

warning:
when handling your television constantly hold it instantly up (like your watching it) or laid flat. Any force carried out at odd angles can damage the delicate glass front.

The vicinity we can be operating on is indicated. See "Step three" for an growth.
Step 3: dispose of Wiring Harnesses From Circuit Board
samsun capacitor
take away the 7 exclusive wiring harness located on the circuit board. A easy tug on the connector clip (no longer the wiring) should be sufficient to put off them.
Step four: eliminate Screws conserving Down Circuit Board
Samsung
take away the 6 screws shown at the image above and do away with the circuit board from the television chassis. This board is a electricity deliver board and no longer in particular sensitive, but it's far always a great dependancy to address these boards cautiously and through the edges.
identifying horrific Capacitors
generally, but no longer always, capacitors will display seen signs of failure. There are two essential kinds of seen failure.
Bulging Vents:
when it fails, the chemical response within the capacitor can produce hydrogen gas, so capacitors have vents cut into the tops in their aluminum cans. those are supposed to interrupt and launch the gasoline that has constructed up in the capacitor. So, a capacitor which has failed can show bulging at the pinnacle. beneath are a few examples.
Leaking:
some other signal of a failed capacitor is leaking fluid (electrolyte). this may be an orange or brownish discharge from both the pinnacle or bottom of the capacitor. normally, with leaking the capacitor can also be bulging. but a capacitor can bulge but not leak.
once more, we need to emphasize that capacitors do no longer continually display visible signs of failure. however, in case you see signs of this on your board, you could be confident that you're close to solving your television. in case you do not see those signs of failure, but your television had the inform-tail clicking sound, you still may be fairly positive the the stairs underneath will fix your television.
Step five: figuring out the trouble Capacitors
clicking
if you have a Samsung 550 series liquid crystal display (and possibly different models), and you got here to this site because your television might not begin, and it makes a clicking sound, then the photograph above suggests the capacitors that must be replaced in the crimson container. when you have a exceptional make or model you may need to visually check out and replace any broken capacitors.
below are real closeups of my tv's board. notice how the blue capacitors in the foreground are bulging. those are the capacitors i'm able to update. All different capacitors appearance ok. If you may locate replacements for all 4 of those capacitors, and any others that show visible signs of going awful, I recommend replacing them all whilst your in right here.
I couldn't find the particular replacements for the "black" capacitors (820 uf 25V) at my nearby digital keep, and when you consider that they regarded adequate, I simply replaced the the bulging ones. but again, if you may find replacements, and because the capacitors are cheap, replace all 4 of those if viable (and every other ones showing signs of harm) whilst your working in right here.
Step 6: take away Capacitors
Capacitors have polarity. What this indicates is, like a battery, they've a high-quality (+) and a negative (-) side. earlier than eliminating any capacitor, notice which facet the white stripe of the capacitor is dealing with. you'll need to position in the new capacitor within the same path. You likely mentioned on my images that I definitely made a word on the aluminum warmness sink with a pen.
Now which you've diagnosed the capacitors that appearance awful, turn the board over and carefully discover exactly which points at the board the wire leads from the these capacitors. Circle them with a "sharpie" kind pen to preserve track.
clutch your buddy and have them assist you on this next step. Balancing the circuit board on its facet while using a hot soldering iron and pliers may be a bit difficult.
Plug inside the soldering iron and provide it 10 minutes to get hot.
With the circuit board on its area, have your pal take hold of one of the capacitors with the pliers and observe a totally gentle pulling stress. follow the tip of the soldering iron to 1 lead at the returned side of the board and hold it there till you notice the solder soften. Now transfer to the other lead until it melts. maintain going back and forth at the leads. whenever the solder will soften quicker. After going from side to side a couple instances the capacitor will without problems pop out.
Repeat for every capacitor that you are changing.
let the iron do the work. If the capacitor does no longer easily pull out, do no longer pressure it.
Step 7: Time to buy groceries
Capacitors are rated for his or her software and you must update like for like. There are 3 rankings to become aware of:
1. uF (micro farads)
2. Temperature
3. Voltage
You need to match uF and the temperature rating precisely. there may be a bit of wiggle room at the voltage, however best in case you're increasing it. Do now not replace a capacitor with a lower voltage rating then the one eliminated.
frequently you could find replacements capacitors at your neighborhood Radio Shack. My Radio Shack did not have suitable replacements so I needed to visit a unique electronic store. If all else fails, and you can wait, you can continually buy replacements from Amazon.com.
For the Samsung LN46550A, you may want 1000uf 10v Capacitor 105c excessive Temp, Radial Leads or 820uf 25v Capacitor 105c high Temp, Radial Leads.you'll word that this specific capacitor is one thousand uF, 105 tiers and 10 Volts. I changed it with a capacitor that is a thousand uF, 105 degrees and sixteen Volts. i have seen this restore successful with a capacitor up to twenty-five Volts, however I would not cross any higher than that.
Step 8: Time to install New Capacitors
Insert capacitor, making sure to region the negative facet in the precise area. If there is hard solder inside the hole, actually observe the soldering iron until solder melts and slip capacitor leads in.
Bend lower back the leads to hold the capacitor in area.
cautiously clip the leads in order that most effective approximately 1/eight" is sticking out.
location your soldering iron and solder on lead till the warmth melts the solder. as soon as solder melts onto the lead, follow the iron at the lead and solder some instances to melt the solder cleanly on the lead. if you have solder flux, the solder will make a smooth connection.
Capacitors established. If there's any flux or solder residue, surely easy the location with a moist material.
Step 9: reverse the process
samsung
1. connected the circuit board with the six screws.
2. Reattach all seven wiring harnesses.
three. update the again cowl.
4. turn on tv and be glad which you shop yourself a ton of cash.
