Hi there. Check for Dry solder joints around IC902,IC955,etc on Main board. This should sort your problem. IC902 supplies the Digital Board which in turn runs the fan circuit. This is why you won't have sound either. Be sure to unplug from mains and don't attempt if you do not have some experience in electronics. Hope this helps. Regards

    I had the PROTECTOR (FAN). Solder joints were bad as mentioned by Justin Smith. Melted all, adding more solder material. Problem solved, thanks!

I need a motherboard for a sony STR-DA50ES audio receiver and no shop was able to find one.

These boards are no longer available from Sony. What is the problem you are trying to solve? I have never needed to replace the entire board. One other option is to locate a "broken" unit from shop or Ebay and use the board from there.

If you can describe the problems, perhaps we can help to repair the existing board.

Sony DA50ES makes loud and scary clicking noise after its been on for about ten minutes, its loud enough to be distracting and annoying while watching movies. I'm wondering if I need to buy a new receiver...

Is the noise audible through the speakers or is it a physical clicking directly from inside the receiver?

If the former, what source(s) do it and are they digital or analog?

It doesn't appear there is a fan so NO physical noises should emanate from the receiver. I'd suspect an arcing component or something electrical. THAT might be dangerous to the receiver or even a fire hazard. Get it looked at.

Sony str-da50es. Does not power when power button is pushed.

Hi,
This problem is very common in this model the solution is to replace the fuse with improved one 10A 125V of type CES710A having part No.1-576-695-11. Remember that this fuse would be larger in size of earlier one so that you have to drill it first in the holder and adjust the fuse to a proper space of 1.4 drill bit.
Do the changes and your product work fine.
Thanks.

The word protector puts on when power to stereo is turned on...

This is not a fuse problem. The rotect mesage indicates that the unit detected a problem and shutdonw the unit to prevent further damage. Disconnect the speaker wires and try turning on the system. If protect still occurs, there is an internal problem *usually shuorted output transistors) that will require service. If you can solder and wish to attempt the repair yourself, update this and I'll provide additional details and instructions.

It blinks PROTECTOR

This means that the unit detected a problem and shut itself down to prevent further damage. The normal cuase of this is a defective transistor in the final amplifier stage. Figure on $15-$35 for parts plus the local labor rate for the total repair.

Sony STR DB-930 Receiver jumping into protector mode

I went through the amp/receiver and used small star washers on all the grounding screws I could find including the one securing the transformer, cleaned dust off all circuit boards, checked output transistors and fuses, all OK.

Re Assembled unit and it worked OK.

I will buy a fan and fan it to avoid sourcing heatsinks for the previusly suggested IC's.

Thanks for the technical help, sure solved my problem.

Regards

Darryl.
