Question about Sony STR-DA50ES Receiver

11 Answers

I have a sony strda50es I fell asleep while watching a movie and the unit was left on over most of a warm night. It seems to have overheated, when I woke up it had message (just -doesn't mention ) I've unhooked all connections and unplugged my unit overnight and plugged it back in the next morning, with nothing connected and still getting the message. I've tested all the visible fuses (6 I think). I'm looking for help troubleshooting my problem further. I dont have a lot of electronics experience but think I could handle the repair with help. Sony wants $250 to repair it. It's not worth that much anymore and I dont have the heart to trash it - it's been good to me :) maybe time to buy a new unit but would like to try to repair this and NOT just trash it. Is it possible to walk me through the troubleshooting? I imagine the service manual has a series of debugging steps to follow to narrow in on the problem. - anyone willing to work with me?

    thanks for your reply I thought I covered most of your suggestions in my question.



    is your solution to buy a new unit?



    I'm looking for someone to walk me through troubleshooting of the unit.



    someone perhaps with access to the service manual - not sure if this will entirely help or not.

  • winy68 Jun 15, 2009

    I tried the suggestions in this solution.

    the unit is obviously not in warranty or I would have taken it in.

    I'm looking for help troubleshooting my problem.

  • winy68 Jun 15, 2009

    thanks agian Rylee.
    i do know how to solder...
    but dont know enough to troubleshoot my problem.

  • winy68 Jun 15, 2009

    yep forgot to mention i blew off all the dust when i checked fuses.
    I dont think reconnecting is worth-while since I get the protector when it's standing alone.

    also should mention that i'm getting the 'protector' message not 'protector fan' I saw another post regarding the fan issue checked that fuse it's ok.
    lastly my fan doesn't cycle on before i get the protector message, it only takes a few seconds to get the protector message it seems to happen right after power up process finishes.

  • winy68 Jun 15, 2009

    thanks mr rabbit
    i already have the user manual
    I was thinking the tech manual or service manual would have debugging procedures.

  • winy68 Jun 15, 2009



    Ya this is what i'm looking for,

    I had someone tell me that the problem is likely a shorted audio output ic.



    either way would you be able to work with me to troubleshoot and fix the problem (replace parts).



    thanks

  • winy68 Jun 16, 2009

    I have a .pdf of the service manual dont know how to send it to you.

    cant seem to attach a file.



    do you know how?

  • winy68 Jun 19, 2009

    thanks for your response - been away thought I had a guy helping me but he dropped off?



    your advise sounds like what I'm looking for, are you willing to help walk me through this process?



  • winy68 Jun 22, 2009

    thanks for your post and info.



    I'm really hoping to find someone who can walk me through debugging the problem

    (testing the capacitor or fried component) and replacing it.

  • winy68 Jun 22, 2009

    thanks
    I already tried these and covered this in my help request

  • winy68 Jun 22, 2009

    thanks
    I've tried that

  • winy68 Jun 22, 2009

    I downloaded a pdf of the service manual, it's not what I was expecting it's entirely schematics.

    which I dont know how to read. I was expecting a series of items to check to isolate my problem.

    which seems to be either the output circuits or power related (the unit does power up but then gos right to protector).



    I'm new to the site and perhaps the level of help I'm looking for is not available?

    I can upgrade to high pay support if I can get specific, detailed technical, assistance.

  • winy68 Jun 22, 2009

    hey sorry dont know how to rate you.

  • winy68 Jun 22, 2009

    hey wow,

    I missed your last two replies,

    sorry I'm new to this site and haven't quite figured it out.



    I'll take pics for sure - good idea

    How can I send you pics and/or the service manual?



    I have a fluke digital multimeter (i'm rookie with it).

With all speaker wires disconnected and still showing the protect message, the short is internal. This is a rather common failure for these units. The output transistors are shorted themselves. These are relatively simple to replace and run about $15 each. Any service shop that repairs audio can fix this easily. Usually, once the outputs are replaced, you can get many additional years of service from the unit. Yes, it is worth it (in my opinion).

A repair of this nature definitely needs access to the service manual. It can be purchased at the above link for a very fair price. That way you can at least try and fix it or know that its not worth the 250$ repair as you could replace it over that option. If you still need assistance let me know, and please take a moment to accept and rate my solution accordingly.
Thank you,
Lee

There are only two ways if the home theater system is giving protector message.
1. if the fan is overheated
2. the board in the receiver is busted.

since you have specified that the message didnt mention fan, i suppose the board is the problem
check out for the following things,
1. if the capacitors in the board are bulged than the normal size.
2. on the backside of the board if the parts have a black or burned view.
if any of these conditions are right then i am afraid you have to take it to the service center, to replace small parts in those. since only in a service center they have equipments to check the reliability of the replaced parts, i am specifying it. i know you are not willing to take it to sony, but sorry to say this only an authorized personnel or a repairman can replace those parts successfully

The best thing for you to do is look inside your amplifier, find the audio amplifier output ic or transistor that is connected in the aluminum heatsink, and get the part number , that would be the first thing to do, have someone look for parts replacement , Google it, while looking for replacement try to visualize where do the wire or path go from the speaker terminals to the amplifier output we are talking about, the trouble lies from that path, if that path draws a voltage of about 1volt or more your protector lights.if any of the speaker output draws more than 0.5v it will also have your protector activated to save your speaker from being damaged.

    if you will have a hard time looking for the audio ic , get a camera and have a picture of it where i can see the aluminum heatsink and i will encircle that part where you have to focus on. have a multimeter ready too, even analog multimeter will do sanwa is preferred, prepare also your desoldering tool , you can also use a non-used tootbrush if you dont have it yet,a notebook where you will write the B+, B-, audio in left, audio in right, speaker out left, speaker out right of the ic, these are the necessary points to consider to troubleshoot your amplifier.and keep a picture of your unit before you try to dismantle anything so that you can put it back safely later, you can use pentel pen as marker for the connectors.the audio ic starts with a 2 or 3 letters followed by string of numbers try to jot it down .good luck

  • Rommel Cana
    Rommel Cana Jun 22, 2009

    so , lets start can you measure the voltage on the biggest capacitor you can see on your unit? you must have at least +25V and -25 V to have the amplifier working, the negative probe of your tester to the chassis of the amplifier.

Hi

In this case your unit needs to troubleshoot with a qualified personnel technician,. because this is power oscillation issues! ok in this issue maybe you have open fusible resistor, if the fusible resistor is over heat this may cause protect in the unit, this is posible that the fusible resistor is blown or cut open resistance. thats need to replace..

This trouble is not so hard and its easy to troubleshoot for a qualified personnel technician,.
and if you have basic electronics repairing, i can teach you how to fix this problem...

Thanks!

    Hi

    Yes sure i can teach you how! audio amplifier is not the answer.. if the audio output is shorted you can not hear any sound, or audio output has own fusible resistor or fuse to blown when it shoted. the topics is the protection not the sounds.. ok 1st you need a multi tester meter, tools for electronics, . and do you have a schematic diagram for this unit? if you have please send it to me to faster teaching to you!

    Thanks!

The power supply has over heated. If it is severely damaged, the protector won't shut off because a capacitor is shot. The protector is a safety feature that will not allow current flow.

I would leave unplugged for couple days and try again. If problem persists, replace power supply or better yet, get new player.

Hello winy68,
please try these steps ..this will solve your issue.

  1. Check the speaker wires and speakers for proper connections.
  2. Reduce the volume level.IMPORTANT: If the A/V receiver is used at maximum volume level, it may enter the PROTECT mode. Maximum volume listening will cause the A/V receiver to run very hot and may drain the output capacitors.
  3. Disable the surround sound option if both the A and B speakers are being used simultaneously.
  4. Ensure the top of the A/V receiver has proper ventilation to keep it from overheating.
  5. If the message only occurs when using a DVD player, the sampling frequency may be set too high.IMPORTANT: Some A/V receivers provide compatibility with the higher sampling frequencies through alternate connections. Consult the owners manual for specific information.
  6. Unplug the AC power cord for approximately 1 to 2 hours to reset the output transformers.

Hi

First try the below mentioned steps:
1. Check the speaker wires and speakers for proper connections.
2. Reduce the volume level.
IMPORTANT: If the A/V receiver is used at maximum volume level, it may enter the PROTECT mode. Maximum volume listening will cause the A/V receiver to run very hot and may drain the output capacitors.
3. Disable the surround sound option if both the A and B speakers are being used simultaneously.
4. Ensure the top of the A/V receiver has proper ventilation to keep it from overheating.
5. If the message only occurs when using a DVD player, the sampling frequency may be set too high.
IMPORTANT: Some A/V receivers provide compatibility with the higher sampling frequencies through alternate connections. Consult the owners manual for specific information.

  1. Unplug the AC power cord for approximately 1 to 2 hours to reset the output transformers.
If protect still occurs, there is an internal problem. It sounds like something on the board heat related (capacitor/bad solder joint/faulty transistor) may need replacing. What I would recommend is on the whole deal, here's your opportunity, shop, get something (with in budget) that has a great deal of flexibility. Is yours out of warranty? Perhaps you're still within your 5 year period? If so, have an authorized center check it out.

Please do accept this solution and revert for further assistance.

Thanks

    Hi



    You are right as you said that you dont have a lot of electronics experience so I thought that it would not be good to replace the capacitor or solder the cold solder joints yourself. Thats the reason I told you to contact a authorized center if its under warranty or buy a new one.



    Please do accept this solution and revert for further assistance.

    Thanks

The screen wont come up. we have had it since jan 08. no problems ever. not dropped-kicked-nothing. possibly left on when the boys fell asleep.


The first thing I would suggest is to try different cables for connecting it to the TV.

If that doesn't solve the problem, then it may have been left on overnight. Most people, as it would seem, who complain about their consoles suddenly dying (aside from the 360's 3 red lights of death) are the same people who leave them running all day/night.

DVD must be overheating


General failure when units warm / hot in high humidity environments. Units operate normally once cold, failure only occurs occasionally then seems OK but when warm fails again
Many PCB's/components have contamination which will manifest themselves in warm and humid environments, so once unit is warm then electrical failure occurs. Clean circuit first in solvent/water combination and retest unit. Failure should dissapear. If corrosion found on joints then reheat with soldering iron which you may see joints bubble then clean PCB thoroughly. Best to soak in cleaner then wipe around with lint free wipe especially around powered components. NOTE contamination is typically hygroscopic and will attract moisture if particularly bad will electromigrate if not too bad then poor SIR Surface Insulation Resistance (occasional unexplained failure) Could go on for long time but this is only the start! Does this sound familiar to anybody ??
