Sony STR-DE435 Receiver - Answered Questions & Fixed issues

This happens to me too... I have a DTR 5.4... Worked well for a couple of years... Now it is shutting off when I have the volume up too high... Although, sometime it just does it at random.... Very annoying...

Least expensive way is thru a 1/8th" mini to RCA adapter into any of the Sony's audio inputs. If you want "Video" as well, that's another story. You would have to check with "Apple" to see if an adapter is available. No "Dock" port on the receiver. Hope this helps.

The receiver has a short in the audio output stage in at least one channel, the parts must be replaced to bring it back up to normal operation.

hello almbom
looks like the unit is going to self protect caused from malfunction of the amplification sector. mainly happens if speaker cables shorten or when speakers used with very low impedance, feel free to cantact for further help
regards

Relay click and Protect display indicates that receiver got problem in output amplifier section and most probably output chips got defective. This kind of problem is not user level repair and local repair shop will help you to get it fixed.
Thanks.

If your turntable has an amplified output, go ahead and plug it in to the aux port. If not, you won't be able to use it with your receiver properly. Look on the back (or front) of your turntable for a knob labeled "level" or "volume", and that will determine if it's amplified or not. Good luck, I hope this helps!

you have defective audio output circuit, like the other ones y might be the transistors or the drivers IC's (integrated circuit ) you need some repair skills to fix this problem.
good luck

this is not a reset problem, you have a defective audio output, is either the outputs transistors or the drivers IC's ( integrated circuit) and sometimes if you are lucky is just loose connections on the drivers IC;s.
good luck

This usually means an output transistor is shorted and the amp is protecting itself. There are usually 2 8 amp fuses GMA type (glass tube) that are located near the large transformer on the main board that also get blown. You can try the fuses and see if it fixes it (10% of the time it will). If they blow again, it will be one or more output transistors are shorted, and the unit will need professional repair.

Protet mode is a special diagnostic mode that starts when a fault is detected.

When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.

Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.

Try unplugging power cable for one hour or so. then connect cable back and see if you get rid of protect state. Sometimes accumulation of electrostatic charges inside circuit capacitors can kick in protect mode. In that case unplugging the unit from main for some times can get rid of electrostatic charges, and reset circuits by draining power completely.
If that was the problem, you will not get Protect when plugging back power cable.

If you do all the above and still get Protect, then there is a real fault.

In that case the unit may be disassembled and tested to find the fault.

If that is the case I suggest contacting the manufacturer at the number listed on the owners manual, or asking a quote on repair to a local technician.

I have the same problemwith mine. the protector sign is on- I do not know why- and do not know what to do about it. Let meknow if you do or if you get assistance and I will do the same. My e-mail address is [email protected]

Hi David, do you want to connect the ST-D505 tuner to the TA-D505 amplifier?

troubleshoot the issue: Reset the CD Changer: Turn off the CD player. Press the CLEAR button. Simultaneously, press and hold down the POWER button on the CD player for 60 seconds. If this doesn't resolve the issue, proceed to the next step. Check for Error Messages: If you encounter difficulty playing a disc and receive any of the following error messages, there may be an incorrect setting or a problem with the disc: NO DISC DISC ERROR CD ERROR TOC ERROR Refer to the instructions supplied with your CD player to verify model-specific information and troubleshoot the issue. Internal Component Repair: If the display issue persists, it might be related to an internal component that requires repair.

Troubleshoot this issue. Here are some steps you can follow: Check Speaker Connections: Ensure that the rear surround speakers are properly connected to the Audio/Video (A/V) receiver. If applicable to your model, verify that the A/B speaker selector is set correctly. If the speakers are connected to the A speaker connection, the selector must be set to the A position. Test Tone Operation: Perform a test tone operation to check if the speakers are functioning correctly. Increase the rear speaker volume or adjust the surround speaker settings to the maximum level. Speaker Size Settings: Try selecting a different size (small or large) for the rear surround speakers in the menu. Surround Sound Mode: Verify that the A/V receiver is set to a surround sound mode. For Dolby ProLogic surround sound, ensure that the center-channel mode is set to NORMAL or WIDE. If your source is a DVD or Blu-ray Disc player, check that surround sound is enabled in the player's menu. The audio being received must be multi-channel. Different Surround Sound Mode: Try setting the A/V receiver to a different surround sound mode. Source Content: Verify that the source you are playing is encoded in surround sound. Note that during periods of mainly dialog, most of the sound may come from the center speaker only, with audio coming out of the rear speakers when there is background or ambient noise. Factory Reset: Reset the unit back to factory default settings (consult your operating instructions for model-specific steps). If applicable, follow the steps for calibrating the appropriate settings automatically after connecting the calibration microphone device. Speaker Wires and Replacement: Check and replace the speaker wires if necessary. Consider connecting a different pair of speakers to see if the issue persists. If you've tried these steps and the problem remains unresolved, I recommend seeking professional service.

steps to troubleshoot and potentially repair them: Troubleshooting Low Sound or No Audio from Rear Surround Sound Speakers: If you're facing audio problems, especially with the rear surround sound speakers, consider checking the following: Ensure that all speaker connections are secure and properly plugged in. Verify that the speaker wires are not damaged or frayed. Check the speaker settings in the system menu to ensure correct configuration. Inspect the speaker impedance and compatibility with the system. If you're using wireless speakers, check their power supply and connectivity. Refer to the operating instructions manual for specific troubleshooting steps. Flexible Circuit Board Repairing: If the issue is related to internal components, you might need professional repair. However, if you're comfortable with electronics, consider these precautions: Keep the soldering iron temperature around 270°C during repairs. Avoid touching the soldering iron on the same conductor of the circuit board more than three times. Be gentle when soldering or unsoldering to prevent damage to the conductor. Important Notice: To prevent fire or shock hazard, avoid exposing the unit to rain or moisture. Do not open the cabinet; refer servicing to qualified personnel. Avoid installing the appliance in confined spaces like bookcases or built-in cabinets.

There is not reason this would click and not turn on. If it just clicked, it would likely be caused by interference from another appliance, typically a fridge or freezer. The most likely reason is a relay in the internal power supply. It will need a Sony Service Centre. https://www.sony.com/electronics/support/res/manuals/4154/41545841M.pdf It isn't a recorded known issue. Sony are high quality equipment so it is worth getting it fixed. https://www.google.com/search?q=sony+icf-cl75ip+clicks+and+not+working ..
