Question about Sony STR-DE595 5-Channel Amplifier

1 Answer

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.

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.

Code 15 when checking appears, experiencing bad idling and speedo not working. when i throuw water all over the enjin the problem is gone for about a week.


how long ago was this car a daily driver (fresh fuel)?
and how long ago did the speedo die... my guess is unrelated to all else but the speedo must work for the EFI to work driving fast, but not
so idling, and not moving.
no year , no model, a 1973 civic? I have no idea.
no engine stated, I4, 6? size?

I love the water, trick but is the top method from finding
bad HV ignition wires, fast. yours does opposite. that.

if car is in USA< no clues there, it's older than 1996.
code 15 is http://www.troublecodes.net/honda/
IGNITION output.

depends on year and engine, type.
on old cars this signal means the ignitor and coil signals are bad
on newer cars, it can be the ECU spark signal bad.
there are 3 ECU designs, in all the years,
OBD1 comes in these flavors
{1}PGM-CARB.
{2}PGM-FI four cylinder engines.
{3}D5Z1 engine except California.

yea?
model and sub model?
engine type.?
and country if possible.... always helps, ?

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.

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.

2 year old 360. Never uninstalled. Power good,


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

What would cause the concrete weight on the tub to disintegrate (washer is 3 years old)?


Hi,

well it sounds like this washer has suffered from extreme vibration. that can be caused by several things. 1) non "HE" detergent being used. 2) shipping bolts not removed soon enough after unit was used. 3) continual and consistent overloading. 4) a very unstable floor, inefficient pedestal. 5) shock absorbers broke and gone unattended too long after separating from tube and or base/chassis.

bottom line is there are many possible causes of the counterweight breaking apart, (even loose counterweight hold down fasteners) these are just a few.

now the good news...

as long as no further damage has occurred, these units are a dime a dozen at used appliance depots and you should be able to locate a relatively inexpensive replacement part.

hope that helps, I know it sucks...no matter if it's 3yrs. or 13yrs old !

good luck
