Driver for wis12abgnx/xec

Assuming you can get the driver (which comes as a file, i.e. software, not hardware) how would you install it on your TV ?

According to the 'Technical Information' link on the Web page that you can access via the link I attached with my answer, your adapter is compatible with WiFi-ready Samsung TVs and AV equipment produced between 2010 and 2012. If your TV is not a WiFi-ready Samsung TV or is one produced before 2010, well....If it is a Samsung TV produced after 2012, it probably has WiFI built-in, in which case you don't need any wireless LAN adapter, Samsung or otherwise and the TV did not recognize the adapter because the USB port on the TV that you plugged the adapter in is meant to be used for other devices, e.g. flash drives or portable hard drives.

Aug 30, 2014 | Samsung WIRELESS LAN ADAPTER...


I have a 46" Samsung LNT4661FX / XAA LCD TV. I pulled the back off and noticed 2...

For this tutorial, I will be addressing a common problem experienced by many Samsung LCD, flat panel TV owners these day... "My Samsung TV keeps clicking for 20 minutes before it comes on" or "When I press the power button on my Samsung, nothing happens" or "When I turn my Samung TV on, there are white dots on the screen" or "When I turn my Samsung TV on, there are multi-color vertical lines on the screen"... there may be more, but these are the most common I know of. The models are numerous and seem to stretch from 08' - 09'. If you are having this issue and want to fix it yourself, read on.

TOOLS: #2 Philips Screwdriver, Wire Cutters, Soldering Iron, Desolder wick (with Rosin), Rosin Core Solder, Replacement parts (will be determined after disassembly).

The first thing we need to do is unplug the TV and move it to a good work location. You will need a soft place to place the TV, perhaps on a carpeted floor or on a blanket placed over the kitchen table ;).

Remove the 4 screw for the stand (RED area) and then pull the TV off the stand and place the TV face down on you soft work surface. Remove the 4 large screws (GREEN area) and the rear cover screws (YELLOW areas). Now remove the rear cover (screw location may vary depending on your exact model, so please make sure have them all out first).

Depending on your model, you may have a metal shield covering the boards. If not, you can skim ahead...

There are 2 major boards that will be front and center inside your TV. On the left we have the SMPS... this is where we will be working. So, we need to remove the shield cover to get to it.


Now that we have the cover off, we are able to take a closer look and locate the faulty parts. Have a look at the upper right corner of the SMPS (Switch Mode Power Supply). You will see a cable going over to the main board on the right... in this area you will find the problem.

The faulty parts are capacitors. The tops are generally swollen and often have blackened material exposed or leaking from their bulging tops.

You will need to identify the electrical value of the parts and locate suitable replacement parts (try Radio Shack). The values may be 1000uF 10v, or 2200uF 10v... whatever they may, you replacement part have an identical uF value but a higher v value... ex: Original, 1000uF 10v -> Replacement, 1000uF 16v. This will help prevent this problem from reoccurring.

Once you have the replacement parts, you are all set to install them. So, unplug the connection on the SMPS and remove the screws from the board. Heat up that soldering iron and remove the capacitors. Use the Desolder wick to clean up the pads, this will allow you to insert the new capacitors with ease. Be careful, these parts have polarity. This means that they need to be installed the same way you removed them... positive to positive and negative to negative. Each capacitor has a negative terminal, each mount location has a negative hole and it is indicated by the wide black band. After you insert each part, fold the legs over on the solder side of the board so that the part does not fall out and stays in position. Once you have all the parts reinstalled, solder them in. Make sure you make a clean electrical connection. Now use your wire cutters to trim the excess legs. Be sure to trim them close so that they don't touch any other electrical connections on the board.

Your SMPS is now fixed and ready to go... reinstall it into the TV and connect the wire harnesses back up to the SMPS. Double check your work. Are all the connectors back in place? Ok, now you should test your work before putting the whole TV back together. Prepare the AC cord, use an extension cord if needed. You will need to flip the TV up on to its top edge (upside down, screen facing you). Plug the AC cord into the TV and press the power button. Do you see the Video/Input indicator or RF snow on the screen? If so, well done! If not, unplug the TV and check you work.

You are now ready to reassemble the TV and return it to service.

** If you need some assistance in the soldering area, please have a look at my Tip "Soldering on the kitchen table, Class 101". I cover the actual soldering of a capacitor in more detail there.

If you have found this helpful, spread the word and/or leave me some feedback.

Delete button not working ( Canon EOS 400D )

1) Put lens or camera cap on, go to a dark room to be sure if you want
2) Take JPG+RAW shot, maybe at different ISO and shutter speeds, one could be 30 sec/ISO 1600
3) Press menu, go to Settings 2 tab, and press sensor Cleaning: Manual, then OK. Wait for 30 seconds or more (is this necessary?) The mirror inside opens, but since you are not removing dust, this has really no effect, but it seems that after doing this, the camera remaps the dead pixels.
4) Take another JPG+RAW shot, compare with shots from 2) - same shutter and ISO

I have replaced the spark plugs, wires, coil, distributor cap & rotor, coil wire and my 92 wrangler, 4.0 L HO will crank but not start. I pulled a plug and grounded the casing, cranked the engine and...

a good start, (no pun) spark renewed parts
good. always good. a full tune up.. for real. (spark)

that distrib device is called a CMP, cam sensor!
the flywheel has CKP sensors. to...

but the reason you cant find this is you lacking a scan tool.
the PCM can cuts spark for many reasons.
the ASD relays does that. by command of the PCM

The PCM drops the relay for 1 to 8 reasons.
minus 1 , your car has no IMMO SKIM key.
but here is how to diagnose all JEEPS, (not fake MK jeeps)
first is to understand the ASD relay.

to do the tests takes 2 persons, unless you are a Xmen. guy.
the JEEP LAW OF 2 SECONDS must not be ignored,
2 full seconds. rule.
this rule applies to spark and fuel,

1:fuses good. test them.
(key on CEL glows, check engine lamp must glow or PCM has no power) does yours?
2: man 1, cranks. (car can crank with DEAD PCM) yup.
3: man 2 , (or WOman) tests spark using a test spark plug
at say #1 front, (easy bend over) lazy we are.
use a real spark plug. ok>? new. or not shorted.,
you ground the shell (this is a 100 year old test, not magic and is done by every mech, alive.) google how to test spark
and not get electrocuted, (got a pace maker?, keep hands in pockets)
4: the key on ASD closes and engine cranks and spark happens for 2 seconds, or not, if the spark ends just as the ASD drops
a hard cold fact.
if there was not spark for 2 full seconds, then sparks dead.
the PCM must be scanned.,
if you cant scan you get to shot gun all day.
i have a scope , you dont but i can see if the pcm is pulsing the COIL.
you cant. so get to guess that too.
if the PCM is not pulsing said coil (lets pretend coil is good, i can bench test them, easy)
then the PCM has BAD INPUTS>
or CKP
tops the list. of shot guns, seems like 1000s replaced here
and not one fixes it.... but goes on.. .. and on because....

best is to own a scan tool to fix any jeep 1991 to now.
or go broke every time a part gives up the ghosts.

the keyon 3 times tests.
can find problems , but NEVER ALL problems, its blind to many.
its just toy really, but has value, if if works.

I dont remember in what order from #1 plug to#6 do the wires go? on chevy 4.3 L

Firing order 1,6,5,4,3,2. To find number 1 plug at distributor set timing mark to top dead center on compression stroke and with distributor cap removed rotor will point to number 1 cylinder in cap. Also number 1 cylinder is on drivers side all the way to the front the next cylinder behind that is number 3 and then 5. So passenger side all the way from front will be 2,4,6 at the firewall. Number 1 plug wire will also be the second longest wire in most cases or as long as number 2 cylinder. Hope this helps.

I have to put the plug wires back on the distributor.

okay remove your driverside sparkplug the one closes to the front this should be #1 piston put a screw driver in the hole but dont let it bind, slowly click the starter until the srew driver come up all the way up this is top dead center TDC now look at the rotor and where the cap lines up this #1 second is#8 piston on the pass side closes to the fire wall or cab so, on the engine #1 piston234 onthe driver side 5678 on the pass side and in order on the cap it should be 1 8 4 3 6 5 7 2 also make sure you didnt drop the dist in wrong and hav it 180 degrees backwards dont get frustated stop and try again later also make sure this is the right firing order for your dodge i gave you a chevy fire order but i am almost positve this is the order for all v8s

Samsung LNS4041D will not turn on

My Samsung LN-S4041d starting clicking and within two days would not turn on. I found an article online concerning the same problem with leaking capaictors. I pulled out the motherboard and my capacitors cm812,cm811,cm817, cm806 were leaking and/or bulged. I went to radio shack and purchased 4 1000uf 35v replacements. It took about 45 minutes to install, which I had never done before, and the TV works perfectly. It cost me $1.59 for each capacitor, $9 for a soldering iron, and $4 for rosin-core solder. Hope this helps your situation.
