Question about Sony STR-DA3000ES Receiver

1 Answer

When I power on my Sony STR-DA3000ES is gives an error code that first says "STREAM" with "(unlock)" below it, then goes on to display a flashing message "PROTECTOR" with solid "check code 22" below it, then turns off.  What does that mean? How do I fix it?

    there are not yet speaker cables connected.  It happens when the unit plugs in and powers on without any connections to it yet.

Incorrectly connected speaker cables is a common problem that is easy to do, but easy to fix. Check your connections.

    If it does this without ANY connections to it at all then a short can't be to blame. At this point, I'm doubting the next step will work but it's worth a shot before sending it back to where it came from for repair.

    Plug it into the outlet, and when you press the power button hold it in until the unit "clicks." It might take upwards of 15 seconds to do so. Then try again to power it on.



    If the problems still exists then it sounds like the amplifier section may be damaged.



    May I ask about when exactly was the first time it did this, what was connected?

This means that there is a short detected on one of the amp outputs. Try disconnecting the speakers from the back of the unit and power on. If fault still persists then likely you have a bad output ic or FET (transistor). If fault goes away after removing speakers then plug them in one by one to see which is the culprit.

My sharp tv model LC-60le640u don't come on just have a white blinking light on the bottom


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

What r the codes for ge universal remote for kirsh home theater system model k3


Set-up (Programming) procedure is too much to type in here, and is not practical and it will differ brand-to-brand remote controls. If you wish to get more; check the sites linked here. The site has set-up code list & set-up procedure to many popular brand remote controls. The site has general set-up codes to check with TVs and other devices are given, in the order of the 'device's brand name list' in alphabetical order. Set-up code list to many brand remote controls also is given. Pull up older posts.

Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.
This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.
Search the site by type in the "brand name" to your device; to which you want set-up codes; in the "Search box at the top right of the display window" to get gathered related posts.

I have a Toshiba Satellite A665-S6088. The last time I used it was last night and everything worked fine. It works with Windows 8.1, it has for a few months now, never had any problems until now. No...


Unplug the unit from ac power. Remove the battery. Wait a minute. Press and hold down the power button for 30 seconds. (Yes, I know, nothing will happen visible). Replace battery. Plug unit back in. Now try the power button and see if the unit resets. Sometimes this helps when all else fails especially with a computer which has "hung up" like yours. Let me know if this worked!

How to reset my combination lock number on ipod A1236


Hi William
If you have forgotten the code or put the wrong code in your ipod, you can unlock the Ipod by doing the following:
Connect your IPod to the primary computer you use it with (the first one Ipod synced with), and open iTunes.
When you disconnect iPod from the computer, it will no longer be locked.
If you can't unlock Ipod using either (the code or connecting it to the computer you use to manage its songs). . . you can restore your ipod to factory settings using ipod Updater.
Please note that this will erase all data on your ipod.
Afterwards, you can add your music and data back to your ipod.
If you want to change the primary computer that your Ipod is associated with, do this:
1. Restore your iPod. WARNING: The restore process cannot be undone.
All of your songs and files will be deleted.
Always make a backup of your important data.
2. Connect your ipod to the computer that you want to be the primary computer.
3. Open iTunes and synchronize.
If you can't unlock your ipod and you don't have access to the primary computer, your only option is to restore the Ipod, which will erase all music and data.
Please take time to rate me
