Protect Mode With Sony str-de595

I have had this amp for several years now. I have been experiencing 2 separate, but possibly related problems with this amp:

1) It has always gone into "protect" mode when playing DVD 5-channel music albums at even low volume. It doesn't happen immediately, but usually after about the 2nd or 3rd song on the album. With films it was always fine however at any volume.

2) In the past few weeks, it has started going into protect mode with any 5-channel DVD movies as well at even mid-volume.

Any help would be appreciated.

    Dear Robert,
    I have a Sony Amplifier STR-DE545. It goes into "Protect" mode just seconds when I turn it on no matter which channel (DVD, Tuner, Video, CD...) I use. Do you think I am having the same problem as you mentioned to STR-DE595?
    How much does it cost for fixing it by a repair store? I am debating if it is worth to fix it.
    Thank you for your help in advance
    Henry

Hi snark63

Ypou have an intermittent problem that sounds to be heat related... the more work the amp does, the more heat generated by the output stages. This will be aggravating some poor solder joints that are cracked or dry. The unit needs some repair work done in these areas. If you have good experience with a soldering iron, the cure for this is to resolder the power stages of the unit, or any other solder joints that look to be failing.

I am more than happy to answer any other questions you may have about it, please get back to me here, or use the ASK function to go straight to me :) If you are still unsure, have problems, or we need to look at the situation more deeply, then before you give a rating for this advice, hit the ASK button Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.

How can i solve a fault with sony STR-DE595 which displays protect?


Protect mode is entered as a result of overload or component failure. Cold solder joints may be a factor as well.

O2 sensor bank 1 sensor 2 location 307 1.4 2004


Notes in relation to bank numbers
•Bank 1 always refers to the group of cylinders which includes No.1 cylinder.
•The majority of small engine European vehicles will only have Bank 1 sensors fitted (i.e. 1 x Front & 1 x Rear).
•An inline 6-cylinder engine may have cylinders 1, 2 & 3 referred to as Bank 1 & cylinders 4,5 & 6 referred to as Bank 2.
•V configured engines would normally have Bank 1 & Bank 2 sensors, with again Bank 1 referring to the group of cylinders which contains No. 1 cylinder.
Notes in relation to sensor numbers
•Sensor 1 always refers to the front / regulating (Upstream / Pre-cat / Upper) sensor.
•Sensor 2 always refers to the rear / diagnostic (Downstream / Post-cat / Lower) sensor.
N.B. Some larger capacity vehicles may have 2 rear / diagnostic (Downstream / Post-cat / Lower) sensors on the same bank, which may be referred to by EOBD codes as sensor 2 & sensor 3. Sensor 2 would relate to the rear sensor closest to, or in the catalyst, with sensor 3 relating to the rear sensor furthest from the catalyst.
Notes in relation to position
In some catalogue entries, a sensor will be listed as fitting in left or right position. This is always taken from the point of view of sitting in the vehicle (i.e. For UK RHD vehicles Right = Offside, Left = Nearside).
Correct identification of the relevant oxygen sensor is more important than ever as many vehicles now may have devices such as temperature, pressure and NOx sensors fitted to the exhaust system in addition to the oxygen sensors.

I have a Sony STR-DE 597 reciever. I have been using it fine for a few years with no problems and it sounded great. I turn the unit on recently and a message was displayed on the unit that said PROTECT....


Protect will usually show up if the receiver was turned up too loud to the point where the speakers will crackle, the receiver will switch to protect to not damage anything. Unplug it for about 30 seconds and check all the audio wiring in the back to make sure everything is plugged in good and tight and no loose cables or stray pieces of copper audio wire and plug it back in.

Our new 48" Viking side by side does not feed ice cubes adequately. If you need several glasses of cubes it stops feeding and when one opens the freezer door they are piled up and fall all over the floor....


I experienced the same problem several times with our VCSB483DSS also.

What I found was that the ice come down the chute side way and got stuck at the flap in the door. As you continue to press for ice, the machine pushes more ice & they all back up in side the chute and in the door, ready to dump on unsuspecting person who open the freezer door.

I think the the problems are:
1 - over application of foam insulation in the chute pathway in the door.
2 - possible bad timing on the flap opening causing the falling ice to get stuck.

My solution for the past 6 years:
1 - clean out the over application of foam insulation - this reduce the incident frequency from once a month to once or twice a year.
2 - inform my family member that if while you pressed for ice, and the ice is not dropping, but you hear the motor still cranking away, stop pressing for ice immediately. Stick you finger up the dispenser to make sure the flap is open, and push the ice to un-stuck them. And finally, be prepare to get 2 cups full of ice.

Viking may make professional quality fridge (13 years experience in restaurant business), but ice & water dispenser is not their strong point.

The SONY STR DE595 goes into "protect" mode upon turning it on.I recut all speaker wires & vacuumed the receiver ...unplugged,differenet outlets...etc.Any advice?


The protect thing is to do with an overload. It's more than likely that something in the main amp section has failed (perhaps a transistor on the big heat sink). The cause often speaker wiring touching together. You should look carefully at the this section for damage or burning. If you have a ohm meter you can test the transistors. If you place the probes on the terminals of each transistor and you get a responce like you had touch the probes together, you have located the source of the overload.

Raymarine "DSM connection lost"


Murray,

Has the DSM and the E120 software been upgraded to the latest software: 4.12 for the DSM and 5.52 for the E120?

Try this first. You can download the software off Raymarine.com and burn each to a separate compact flash card.

I have seen many problems like you are experiencing solved with this simple change.

If this doesn't solve the problem, the DSM will have to go back to Raymarine for repair.

The problem you are experiencing is closely related to the dreaded RROD (Red Ring of Death). It has the same causes and solutions. I suggest getting an experienced person to repair your console for you. Take care that no one is doing the "Towel Trick" instead of an actual repair.
I run an electronics repair business and would be happy to fix your machine for you, email me at Jordan@jordanselectronics.com for more info
