    the Niles ZR-4630 is not a CD or tape player. It routes the signal from the receiver to up to 5 other locations to allow different locations to listen to different functions.



    Any ideas for this?

    when turnng on the power, it initially appears to power up regularly, but afer hearing a couple of clicks the mesage, "E 01" appears. There is power to the unit but none of the other locations respond. the Niles ZR-4630 is not a tape or disc layer. it receivesthe signal from the receiver and sends it to other rooms so we can listen to different functions in different rooms.

You hear a couple of clicks that is the indication of loose contact or cold solder parts joint. The common causes circuit problem is cold solder or loose connection that why the machine function abnormally and it causes the machine to overheat and the receiver is in protect mode then error display come out. A cold solder joint is where a lead of a component is not soldered at a high enough temperature and results in a bad electrical connection which can respond to physical shock and thermal stress. When you open the receiver look on the front and back of the board along the defective circuit to see any components that look like they are not soldered effectively or the solder connection is cracked or broken. A cold solder joint looks dull and/or bulging unlike the smooth and shiny normal solder joints. Each component parts are soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the receiver turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough. Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection. Its better you re solder all components parts joints in power supply board and also in audio power amplifier section board input /output. Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing. If you're not experienced with troubleshooting and repairing electronics, I strongly suggest look for professional service or bring it to authorized electronic repair shop. Good luck? Regards: VOTIT

The E01 is a mechanism error. Basically the unit is telling you that the cassette is tuck (like you don't know that already!!). What has happened is that the mechanism has jammed. No cleaning of the lens or rails or alignment will fix this. This is strictly a mechanical problem. Sometimes you can open up the unit and see what has jammed and clear it. I have seen CDs that have not seated in the carriers correctly cause this. If you can move the CD enough to seat properly, it may clear itself. If n ot, than the unit must be dis-assembled and rebuilt. This involves "re-timing" the gearing inside that may require a service manual.
The slider mechanism, depending on the age of the unit and the manufacturer, consists of the small chrome rail, a drive motor, a small gear assembly, and (in some units) a small belt that drives the slider unit via the motor. This small belt causes all sorts of problems. If the belt is broken or slipping, it can cause skipping, dropouts, or simply no start up at all. Also, if the belt breaks in the middle of the disc, the drive mechanism gets hair or dirt wrapped up into the gears, or the pick-up assembly doesn’t return to the start position (called home), the unit will (99% of the time) refuse to release the disc, causing it to become stuck inside the unit. There’s a little micro or leaf type switch located at home position that sometimes gets dirty or breaks and, causing this problem also.
If the disc starts to spin slowly and doesn’t come up to speed, the spindle motor that’s attached to the turntable platter is a common problem. There could also be a problem with the spindle motor driver controller IC or the power supply regulator that supplies voltage to the driver IC. If the disc starts to spin and then spins really fast, or stops and starts to spin backwards, your problem is the laser pick-up assembly or the servo control circuit. If you continue to have problems after cleaning and checking the other things listed above, you may have a problem with the player's alignment. Of course, one of the problems you'll face checking alignments on a DVD/CD player is that you’re going to need to use an oscilloscope on most of them. If you have the proper tools and equipment, the first thing to look at is the RF pattern of the unit while its playing. It should be a sharp and clear pattern. If it's dull and smeared, then the laser could be weak.
Also, in these units are very critical alignments called the focus/tracking gains and offsets. When these alignments are off, it can often cause intermittent troubles. As the unit ages and parts change value, so do these alignments, and will need to be checked. In my time as service technician repairing DVD/CD players, 65% of the laser pick-up assembles I have tested were good and only needed a small adjustment. Today's technology makes it unfeasible for a shop to hook up a DVD/CD player, and even some recorders, to their equipment and make these adjustments because of the cost involved.


To clean the lens you must use very little pressure. Take a cotton swab and barely moisten it with plain, non-scented, or oily type alcohol. In a swirling motion, very gently rub the lens until you’ve covered it entirely. Then repeat using the dry end.
If the cleaning didn’t help, don’t despair just yet. You can see if there’s a problem elsewhere in the unit by using a few simple tricks and tips.
First thing you want to see if the unit’s laser is in good working order. This method isn’t foolproof, but most of the time works admirably. When you insert a disc, see if you can look up underneath where the disc sits on the turntable. Observe the laser lens going up and down. If the lens is trying to focus, that’s good! After a few seconds of the lens trying to focus, the platter should start to spin. On almost every CD/DVD unit I've encountered, the unit won't spin unless the laser has properly focused on the surface of the disc. If the unit spins up and and then shuts down, you should check and make sure the laser pick-up assembly slider mechanism is working without any obstructions and that the small chrome rail that it slides on is slightly greased. Don’t go overboard with the grease though, as too much can cause all sorts of problems

Hope it may help you;
ELSE ...

The botom line is that you will need to examine the mechanism for any obvious jam and try to clear it. If you don't feel confident in doing this, please do not attempt it. You would be better off bringing the unit to a repair facility.

Fame !

E:91:01 in DSC-W80


I can't recall all the Sony error codes off the top of my head, but I believe E:91 is that your flash is not working.

Can you take pictures at all or do you get just the error code? If you can take a picture with the flash off then your flash needs to be replaced.

If you can't use the camera you need to first press the reset button, then reset all camera settings to default.

1-3. PROCESS AFTER FIXING FLASH ERROR
When "FLASH error" (Self-diagnosis Code E : 91 : 01) occurs, to prevent any abnormal situation caused by high voltage, setting of the flash is changed automatically to disabling charge and flash setting. After fixing, this setting needs to be deactivated. Flash error code can be initialized by the operations on the HOME screen.

Method for Initializing the Flash Error Code
Initialize
Initializes the setting to the default setting. Even if you execute this function, the images stored in the internal memory are retained.
1 Select [Initialize] with v/V/b/B, then press z. The message "Initialize all settings" appears. 2 Select [OK] with v, then press z. The settings are reset to the default setting.

To cancel the resetting
Select [Cancel] in step 2, then press z.
· Make sure that the power is not disconnected during resetting.

Hope this helps.
