Question about Logitech Z-680 Speakers and DVD218 System

2 Answers

Control and amplification circuit boards are not recieving power

I have tracked the power failure to something inside the subwoofer box. Main power is wired directly into the box with no obvious way to open it, however, the subwoofer speaker does use screws, but the grated cover has no indication on how it might be removed. Using a voltometer, the circuitboards appear to be intact, they show the ability to hold a current, so I have ruled them out as being shorted. The main power line going into the box has power, but none of the wires coming out, going to the board, show any current whatsoever. I conclude that there is some sort of power distribution hardware that has failed or a wire has become loose. My question is, how do I open the box without damaging it?

I have 2 sets of speakers systems for the Logitech Z-680
Both sets included Subwoofer and 5 speakers.

Note: there is no controller on both just the speakers

I bought one set and the Controller went out.
Logitch sent me a new Z-680 system then the second controller went out but speakers work great.
1 system speakers were never used
2 system speakers used for about 4 yrs (speakers work great)

Also have 2 remotes (never used)

Both speaker systems are for sale
Remotes will sell seperatly or with systems

If in need of the subwoofer speakers must go along

Email me if interested

If there are no visable ways to get into the box from the back then you must remove the speaker from the from and gain access through the hole the speaker came out of. It is not too uncommon for speaker units to built this way. Good luck.

Its an eletrical problem, Check the relay on the main contorl(panel fuse box) the one in under the hood, ..

My LG front load washing machine, model WM3001HWA, has no power. What can I do?

Hello Kyle;

My name is Peter. I am a retired field service appliance technician.

You have 3 sensors in your unit, a thermal sensor, a position sensor and a door lock switch. These components will prevent you from running but, would not affect your power.

I assume you checked your circuit breaker to make sure you have power to your washing machine.

The slightest change in power supply, electrical power surge or power outage will knock out your boards. Magnetic fields and static electricity will knock out your boards. Are your appliances near a main power supply line in your home?

All appliance manufacturers recommend surge protectors if you have control boards in your appliance. Individual wall socket surge protectors cost about $20.00 at your local Home Depot or where ever. This is a good investment.

Ok, your have 3 control boards in your unit. One is the digital display board which has nothing to due with power supply.

The others are your main control board and your control panel board. Each of which can turn off power. The highest probability is the main control board. The part number for this board is EBR 44289820. The part cost $225.00 locally. You can probably get it for $180.00 if you search the internet. This is item A450 on the following link.

Remember static electricity can not out a board. Ground yourself by rubbing your hands over something that is steel. Either unplug your unit or turn the power off at your household fuse box. There are several clips holding the board in the casing. you must push outward to remove the board. Inspect the circuit back side for burn marks. If there are no burn marks you can still have a board component failure. DO NOT DISCONNECT ANY CONNECTOR PLUG IN. When you replace the board, you will replace one at a time.

Replace main control board

Is the wall receptacle defective? Have you plugged something else into the same wall receptacle without circuit breaker activating? Test with another appliance that also has the third round ground prong. If this is not the problem then yes an electrical short exists within the treadmill, inspect the cord itself for loose prongs, there may be liquid damage inside from a previous liquid spillage which would cause an electrical short.

Main control board

Cyclic resetting can be the protection circuit kicking in due to one or more of many possibilities.
Some common failures which can cause self-protection:
Insufficient ventilation/ cooling (overheat);
Excess dust (arcing);
Shorting components (overload);
Open circuits (components, tracks or dry solder-joints);
Incorrect load (eg speakers blown or loose wires).....

Have hooked up system according to manual (I think) using HDMI, to Samsung plasma set. Also have audio cable hooked up (from subwoofer to tv). Get absolutely no sound through system. I imagine I have...

Look on the back of your TV for an HDMI port that has "ARC" on it, connect that to the HDMI Out on the subwoofer. Make sure that your HDMI cable supports ARC. That is the only connection you should need to the subwoofer, remove everything else. Other option is an optical cable between the TV and the Subwoofer.

I just discovered this after fooling around with it for the past couple of days!

I have no power at the control board, no code is showing. Has 120V at the unit.

see this and replace if necessary. God bless you
Main Control Module / CCU
The main control unit is the circuit board located behind the console. If the door switch tests good the main control is usually the problem. Check all connections for a goood tight fit. You will need to refer to the tech sheet or service manual to check this further. The main control is easy to replace.

Motor Control Module

The motor Control Module is located inside the cabinet down near the motor. This recieves the signals from the main control module then relays this information to the motor. Check all connections sometimes a communcation problem is just a loose connection. The Motor Control Module is easy to replace. To check this further you will need to refer to your tech sheet or service manual.

I have a vsx-821-k reciever and cant adjust the bass

If the treble is good and is working then the failure to adjust or increase bass output even when it is done can be due to faulty OP-AMP in the BASS circuit. The BASS frequency must be enhance with an amplification and a pass filter with amplification boost and so a failure of this stage can be the reason for non action.You will need to have a signal test on the bass section to confirm the faulty IC.Check for poor solder joint and faulty capacitors/controls.

I have a creative subwoofer which I replaced the two ICs thinking that they were the problem,but now the two speakers dont give out sound but the subwoofer one gives out an outburst of a buzzing sound...

Do not replace a part until you have proved with a signal and circuit test that there is absence of amplification. So I would suggest that you replace the original IC back to the circuit so that we start allover again.
Now you will need a signal tester- an audio frequency( AF) testor so that you can apply the signal and trace. Check the power to the subwoofer output and the main outputs. If present check with signal , check the parameters of the IC to confirm if there is amplification and BIAS to the circuit.
Once confirmed check the feeder resisitors,capacitors, check if any of them is open/short. If not recheck IC and replace once again from original source of spares.
