    I have the same problem and i did the same thing.
    I have the same numbers except for the 3rd line of numbers/letters
    mine is EXETCED2256

    I would like to know what that part is called, where i can get it, and how to take it off.

    I have the same problem. At first I thought it was the Flyback transformer, but more careful listening revealed that it was this other transformer. I cannot find it anywhere. Where can I buy this part?

    I have the same issue TV just stopped operating, I can not turn on or have any audio, the high pitched sound remains unless you un-plug the unit. I purchased the set on Jan. 03' and have had no issues up to this point. Did anyone find the part? Price? Thanks

    I have the exact same problem. How do I fix this? What will I need to buy?

  • Anonymous Jan 21, 2009

    sounds the same to me, but is there anyway to fix it myself? A skilled technician would cost more than the tv!!

  • bajancodgie Feb 11, 2009

LG LED TV no sound or pictures


If you have already been inside of the back circuit board area, make sure that you don't use any type of magnetic screw drivers or any thing that can statically discharge a capacitor etc. Next since you say there are 3 boards present,the board, you are looking for is the power board.How to identify the correct one, follow the AC cord from the plug into the board that it first attaches to.That is the power board.Carefully disconnect any 6 pin or any multi pin connector and mark them for re assembly.There should be 6-8 screws that are removed then remove board.Have a very bright light on hand and carefully examine the board for any broken circuits or burnt components.If found ,go online and search eBay Amazon etc. For replacement board. Assembly is reversed order of removal.

Danby wine cooler refrigerator temperature control won't work


Without more details on what you're observing, I can't say for sure what could be wrong. I can just tell you that I had problems with the temperature not controlling properly, and the set temperature seeming to vary on its own. It turned out that one of the 5-wire bundles that plugs into the back of the controller (PCB) was snugly pressed into the pins on the back of the circuit board, which was causing shorts in the control circuits. I inserted a piece of heavy cardboard in between them to ensure separation, and presto, my machine now works correctly again. So before buying parts, I would suggest you examine the control board and wiring for possible problems like this.

Hi I am hoping that somebody could help me out with that samsung TV which i have purchased before 5 years ago, tv having problem regarding all about with sound of tv (model no-CZ-21K5G7 type-KS9A21K5 SVC...


Hello
you have given me a detailed description of the fault of your Samsung TV. At first, make sure that the "mute" function is in 'OFF" positon. If it is in "ON" position, no sound output will be there from your TV as you know. If it is alright, switch OFF your set by its mains power ON/OFF switch at its front panel. You have to check this first. Keep your ear very close to the speaker side of your TV, and switch it ON by the front panel switch, and listen, whether there is any "Thumb" sound comes from the speaker or not. If there is sound, it means that the speaker is alright, and the sound output section inside the main board of your TV is faulty. If there is no sound "Thumb" from the speaker, the speaker has got damaged, and should be replaced.
The second step needs some skill in electronic work. You must have a good quality multimeter and soldering iron to proceed. Open your TV, and pull out the main circuit board out, keep it upside down, and check for any loose sodering at the audio output side in the circuit. it is a common fault to all kind of TVs that, loose solderings will occur after a long period of use. heating and cooling of these components in the audio output section will result in loose solderings at the termianals of componets. Just resolder most of the suspected solder point by applying a little more solder over it. Care should be taken not to short circuit adjecent sodler points when do this work. If this does not help you, measure the voltage at the input pin of the audio output IC. If it is found ok, desolder it out the audio output IC from the circuit board, and replace it with same type and number. OK.

I have several computers at home, and none og them can recognize this portable device. Hitachi 250 GB Mod: SDM/250RW


1) Power:

It may be the problem that occurs with a lot of USB powered devices jrherrer. Not enough power provided.

The USB cable plugged into the computer, provides signal wires for transferring information back, and forth, and also provides 5 Volts DC for power. (Two D cell flashlight batteries produce 3 Volts DC)

http://en.wikipedia.org/wiki/USB

[ Below shows the Signal pins, and the Voltage pins of the USB B Mini style connector, (Male), used to connect to the SimpleDrive Mini external harddrive,

Pin 1 is for the 5 Volts DC Positive (Wire color - Red)
Pin 2 is for the D- Signal (Wire color - White)
Pin 3 is for the D+ Signal (Wire color - Green)
Pin 4 is not connected. (Or sometimes joined to Pin 5 with a Resistor)
Pin 5 is for the Ground (Wire color - Black)

Just added info in case you wanted to know ]

From what I see the SDM/250RW has a USB port on the side, and a DC Power Jack, used for an AC adapter, also.
(Round port with a pin in the center)

http://www.hitachigst.com/tech/techlib.nsf/techdocs/0C876B7AB91B23988825773F006BEA02/$file/SD_Mini_DS_final.pdf


From what I see stated from Hitachi, and sellers on the 'net, the AC adapter may not be provided.
Many of those who provide a review state that both the USB cable, and the AC adapter is needed to provide enough power. Seems to be a power hungry external harddrive

It's a 2.5 Hitachi SATA laptop harddrive inside that external case. (The Harddrive is 2 and a half inches across in Width. Common size used for laptops)

When using an external device powered by a USB cable there are general guidelines to follow,
A) The USB cable should not be more than 2 feet in length
B) Connect the device directly to your computer, instead of through a hub, or other device, unless the USB hub has it's own power.


2) USB cable:

Could be a faulty USB cable, although I imagine you have tried different ones by now.


3) Interface Circuit Board:

The Hitachi SATA 2.5 harddrive inside the SImpleDrive Mini SDM/250RW, plugs into a small circuit board located inside that external case.

Components on the circuit board may be fried, or the Harddrive may have come loose from the interface.

Loose from the interface
To explain;
The back of the harddrive has connector pins sticking out.
The interface has socket holes which the pins insert into.

Faulty circuit board
The external case of the SimpleDrive Mini SDM/250RW can be carefully opened up, and the Hitachi SATA 2.5 harddrive extracted out.

Another inexpensive external case for a 2.5 SATA harddrive can be procured, and the Hitachi harddrive put in it.

Example of a 2.5 SATA external enclosure,

The picture is fine but the sound is not working. I push the volume and you can see where the volume level is going up. Have tried turning it off and unplugging it to try to reset it but nothing has...


Hello
Picture being Ok, and no sound output, means there is some problem inside the sound output circuit of your TV. It may be due to a speaker fault or an IC fault. You have to find out which of these has fault.
You just place your ear very close to the speaker side, and switch on your TV with its AC mains On-Off switch, not by remote control handset. Listen carefully, whether there is any sound output of any form comes out of it or not. If there is no sound at all you can determine that the speaker may be out, not in all cases. If you have the habit of listening your TVs audio by using a headphone, continious in-out action could damage your TVs headphone socket. If the headphone sockets' contact got damaged, no sound output will come from it to the speakers. Suppose you can hear the sound through your headphones but not throuhg speaker, means that its change over contact has some trouble. You just do this first. Insert a headphone pin into your TVs headphone socket, if provided, al listen to it for sound. If there is no sound from headphone also, Sound output Ic iside your TV has damaged, or not getting proper voltage to it. If there is sound through the headphone, and not from TVs speaker, trouble is related either speaker or the above said socket.
If all the above has no effect, that is no sound either from headphone, of from the speaker, you should go into the circuit board of your tv to get the fault.
Open your TVs back cover, and trace for the sound output section. There will be an Ic used as sound output. Check whether it getting heated some time after switch on the TV. If it overheats without any sound output, it is damaged Desolder it out from the circuit board, go for a same type and number, replacing it will solve the problem. If it doesn't overheat, or no heat at all, check its input voltage. In some cases, loose soldering points on the legs of Ic may also the cause. Check it too. Ok.
If you need any more clarification, ask me through Fixya. Give
a brief explanation about what you have done so far also.

LG DU-42PX12X


Check the controller board, 6871QCH038A. This board is one layer deep into the assembly after the cover is removed. Gently lift the covering circuit board back plane to access.

To do this direct a blast of cold air unto the large chip in the center of the board. If the picture comes back on then you have found it. This means powering the TV while open and this means danger to the novice. Voltage can end your life when you become the circuit path.

Order Part number 6871QCH060Q as the suitable replacement part to this circuit board.

I have a vinotemp it stopped cooling no light and keeps making a ticking sound, I tried to unplug it for a while and plug it back and the ticking sound goes back again but still no light no cooling, please...


You can fix this for $5. You can confirm the problem by taking the back off and see of the red and green led on the circuit board are flashing. They will be steady if the board is ok. The fan is usually just rocking too like it is trying to start. The part is a capacitor and is $5, but you will need to be able to remove and solder a part on the circuit board. If you need the part, just let me know.

Fixing the Zenith 50" plasma


The problem is probably a shorted Z Sustain board located on the right side of the TV when viewed from the rear. The board sells for about $220.00. The pop sound comes from the speakers because the audio circuit is not properly muted before power down.
