Question about Sony HT-7100DH System

1 Answer

Varying sound level

Over a week or so, my HT7100DH system suddenly losses amplitude which I have to restore using the calibration cycle. This problem seems to be happening more frequently.
Have other owners had this issue?

Hi,
I checked schematics of Amplifier unit (STR-K7100) in your Sony sound system HT-7100HD and found that all the data stored in EEPROM IC1131 in Digital board (right side of amplifier)
This IC1131 seems problem as it loses stored speaker level data and got reset for no reason.

You can reset Sound Field data by press and hold 2CH button and press Power button, you will see message "S.F CLR" in front display that shows sound field data is cleared.
Now store speaker level by calibration and check.
Let me know further query/ info by hit "add a comment" button.
Thanks.

Electrolux Dryer Model EDC 5330 runs for about 4 seconds only then stops.


New electronic dryers are smart appliances. Your device is probably equipped with a conductimetric sensor that has a function to measure humidity of laundry and in accordance with that increasing or decreasing the drying time. So, it is normaly that appliance stop if you did not put the wet laundry. In the user manual is described as adjusting the level of conductivity (if featured) depending of the water in your area. The conductivity of the water used to wash the fabrics varies from zone to zone.
The conductimetric sensor is calibrated to a standard value: any major variations in the level of conductivity may affect the final drying result (i.e. the washing may be too dry or too humid).

From user manual:

Adjusting the level of conductivity
Water contains, a variable quantity of limestone and mineral salts of which quantities vary according to geographical locations thus varying its conductivity values.
Relevant variations of the conductivity of the water compared to those prefixed by the factory could slightly influence the residual humidity of the laundry at the end of the cycle.
Your dryer allows you to regulate the sensitivity of the drying sensor based on conductivity values of the water by using the following procedure.

Procedure:
Turn the programme selector dial to switch on the appliance
In selection mode press simultaneously the buttons 3 and 6 until «C0» appears on the digits.26037909-0ttppooyw5gnrrhrzk4a545r-4-0.png

Adjusting the level of conductivity:
Press the button 5 sequentially: the level of conductivity is indicated by the lighting of the horizontal hyphens.

26037909-0ttppooyw5gnrrhrzk4a545r-4-3.png Normally, the appliance is factory-set to the highest level; however, certain models may be configured differently.
Memorizing the new setting:
Simultaneously press down the buttons 3 and 6 until the previous drying cycle time appears again on the display and the buzzer sounds.

Incline not moving


Hi,
Try to do the following hope it will solve the problem.
if its doesn't solve the problem then the the incline motor or the control panel is faulty.
HOW TO USE THE SETTINGS MODE T
he console features a settings mode that allows you to connect your incline trainer to your own wireless network and to log in to your iFit Live account. The settings mode also allows you to turn on and turn off the display demo mode. You may also be able to select the unit of measurement.
Select the settings mode.
Insert the key into the console . Next, select the start menu. Then, press the i button in the lower right corner of the screen to select the settings mode.
Select the maintenance mode.
Press the Maintenance button in the lower right corner of the screen to enter the maintenance mode.
Calibrate the incline system of the incline trainer.
Press the Calibrate Incline button. The incline trainer will automatically rise to the maximum incline level, lower to the minimum incline level and then return to the starting position. This will recalibrate the incline system. Press the Begin button to calibrate the incline system or the Cancel button to return to the maintenance mode. When the incline system is calibrated, press the Back button. IMPORTANT: Keep pets, feet, and other objects away from the incline trainer while the incline is calibrating. In an emergency, pull the key from the console to stop the incline calibration.
Restore factory defaults.
If necessary, press the Restore Defaults button to reset the firmware to the original factory firmware. This will erase all firmware updates that you have downloaded. Press the Begin button to restore the default firmware or the Cancel button to return to the maintenance mode. When the restoration is complete, the words PLEASE CYCLE POWER will appear in the grey box. Press the power switch into the off position. Wait for several seconds, and then press the power switch into the reset position. It may take a minute for the console to be ready for use.
Exit the maintenance mode.
To exit the maintenance mode, press the Back button repeatedly.

OK got your message on the other post (About the van) I am assuming that your Voyager is equipped with Automatic Climate Control. Follow the instructions below and you will get a better idea of what is wrong with your system.

Calibration/Diagnostics
1. To enter calibration/diagnostics test, set parking brake. Start and warm engine to normal operating temperature. With engine idling, turn blower switch to high. Turn mode switch to panel. Open all outlets. Move temperature to full cold.
2. Press and hold rear wash and rear wiper buttons simultaneously for 5 seconds (Until ALL LEDs illuminate). All LEDs should illuminate for 5 seconds. Rear wiper and intermittent rear wiper button LEDs will flash alternately during calibration/diagnostics test.
3. After approximately 60 seconds, if only the rear wiper button LED is flashing, calibration is successful and the system is okay. If rear wiper and intermittent rear wiper button LEDs are flashing, Diagnostic Trouble Codes (DTCs) are present. (See "Reading Diagnostic Codes" below)
4. To exit calibration/diagnostics test at any time, press the rear window defogger button, rear wiper button, or cycle the ignition off and then on. Test will automatically terminate 15 minutes after calibration/diagnostics is entered.

Reading Diagnostic Codes
1. Perform calibration/diagnostics test. If a DTC is present after calibration/diagnostics test has been performed, system will flash rear wiper and intermittent rear wiper button LEDs in sequence. Rear wiper represents code level, and intermittent rear wiper button LED represents code value.
2. Each time the rear wash button is depressed, rear wiper button LED wil cycle to the next code level in numeric sequence. After code level 5 is reached, rear wiper button LED will cycle back to code level 1. See table below.

WHERE IS THE KNOCK SENSOR ON A 2006 CHEVY COBALT TO REPLACE IT.


Not related to the O2 sensor. Located on the front of the engine just above the starter KNOCK SENSOR (KS) SYSTEM DESCRIPTION

PURPOSE
The knock sensor (KS) system enables the engine control module (ECM) to control the ignition timing for the best possible performance while protecting the engine from potentially damaging levels of detonation. The ECM uses the KS system to test for abnormal engine noise that may indicate detonation, also known as spark knock.

SENSOR DESCRIPTION
The knock sensor (KS) system uses a flat response 2-wire sensor. The sensor uses piezo-electric crystal technology that produces an AC voltage signal of varying amplitude and frequency based on the engine vibration, or noise, level. The amplitude and frequency are dependant upon the level of knock that the KS detects. The engine control module (ECM) receives the KS signal through a signal circuit. The KS ground is supplied by the ECM through a low reference circuit.

The ECM learns a minimum noise level, or background noise, at idle from the KS and uses calibrated values for the rest of the RPM range. The ECM uses the minimum noise level to calculate a noise channel. A normal KS signal will ride within the noise channel. As engine speed and load change, the noise channel upper and lower parameters will change to accommodate the KS signal, keeping the signal within the channel. In order to determine which cylinders are knocking, the ECM only uses KS signal information when each cylinder is near top dead center (TDC) of the firing stroke. If knock is present, the signal will range outside of the noise channel.

If the ECM has determined that knock is present, it will ****** the ignition timing to attempt to eliminate the knock. The ECM will always try to work back to a zero compensation level, or no spark ******. An abnormal KS signal will stay outside of the noise channel or will not be present. KS diagnostics are calibrated to detect faults with the KS circuitry inside the ECM, the KS wiring, the KS voltage output, or constant noise from an outside influence such as a loose/damaged component or excessive engine mechanical noise.

Hello russet327,

There should be no difference in the signal on the speakers themselves. It's simply an AC sine wave, varying in amplitude and frequency.

There might be a phase difference that could affect the sound of your subs, but most amps will allow you to adjust or at least select the proper phase. I'd recommend wiring the LOC the same as you have always done it. "Grabbing" a signal before it gets to the factory amp could be even more problematic because the signal will most likely be at too low of a level for your LOC, the wiring may be shielded, and the impedance will be an input impedance in the range of 20-25K ohms instead of the 4 ohms that the LOC is expecting.

Hope this helps.

Suburban 2001 temperature gage fluxuating from high to low


Is it just the gauge or is the engine coolant temperature varying? Does the heater seem to vary in temperature when it is on.
It could be a couple of different things.
One could be a malfunctioning temp sending unit, it has lost its calibration.
Two, your thermostat is cycling open and closed from a weak return spring, worn out.
Make sure coolant level is correct and the mixture is 50/50.
Let me know.
Regards,
