Question about Audio & Video Receivers

Open Question

My Sony STR-D915 receiver is supposed to keep its radio station presets for up to a week during a power interruption, but even a short power outage causes all presets to be lost. Is there a battery inside or something else that I can replace to fix this annoying problem?

It sounds like a bad solder connection. It just needs to be soldered up, if you take it into a shop just tell them it doesn't need any new parts, it just needs to be soldered up.

Or, if you can solder it yourself, or know someone that can, that would be much easier.

I believe it is actually a memory capacitor that has to be replaced. It is soldered directly into the board and requires quite a bit of know-how to replace.

Hope this helps,

Thanks,

How do I do a factory reset on Sony STR-DA3300ES receiver when the published method in the manual doesn't work?


While holding down TUNING MODE, press POWER on the receiver. All preset stations will be erased when you change
the tuning scale.

See some test modes

MEMORY CLEARING MODE
All preset contents are cleared when this mode is activated. Use
this mode before returning the product to clients upon completion
of repair.
Procedure:
1. While pressing the [TONE MODE] and [DMPORT] buttons, press
the [POWER] button to turn on the main power.
2. The message "MEMORY CLEARING***" appears and the
memories are reset to the default values.
3. When done, the message "MEMORY CLEARED*"

If you are a geek then try the SUPER MENU MODE .
Understand how to enter and exit the menu,
then See if Super reset on page 25 helps

Is there an internal battery on the STR-DE345 Sony receiver for the pre-sets? Can it be replaced if there is. Receiver no longer holds pre-sets when there is a power outage.


There is no battery to replace to hold preset channels. The preset channels are held by a charged capacitor to maintain the nominal voltage level to the PLL (phase lock loop) tuner. The capacitor can only hold the charge for a few hours, and then it will slowly discharge - for like a short power outage.

My Sony STR-DG500 wont turn on just clicks once and nothing.


Sounds like faulty psu (pwer suply unit) Amp is going into protection mode. Disconnected all speaker and av wires (only power) turn up volume and see if it stays on. If not psu, sounboard or volume function faulty. If on, connect one speaker L or R. Go to tuner mode to tuned radio station an listen for sounds. If on, connect speakers and av cables one by one and test each one on its own until amp switches off, Investigate from there were problem is. Make sure speakerwires is not shorting out.
