Cooling fan in reciever noise.

Is there a way to not have the cooling fan run all of the time? Mine comes on as soon as you cut the system on and runs the entire time.

Its necessary to run cooling fan because Amplifiers in home theater system produce heat during its operation. If you shut down cooling fan, Amplifier ICs may be damaged due to over heat.

Why is protect is flashing on display


There is a defect that is causing the light to come on. It could be a bad output transistor or some other defect that produces excessive heat. The cooling fan could be at fault too.

The cooling fan should run at all times. Check for dust or any blockage to the fan. If clear then try spinning the fan with a piece of plastic or something to see if once the fan is rotating it continues to spin.

Before shuting off the word protection comes on why? The systems shuts off on its own and the word protection comes on.... is there something I can do so that the system wont shut off on its own?


I've had the same problem with mine recently. I called Samsung and they say I need service, which is a $160 charge...I say ridiculous. I could buy a refurbished system for $130 or less.
So, I've been continuing my research and one thing I think is that the system is eerily quiet - don't you remember the noise the cooling fan makes when you turn this thing on? I remember it being almost deafening - well, it's not making a sound anymore which means to me that the cooling fan is burned out. I'm thinking about ordering one for about $20 to try and fix it myself...but I'm also contemplating just letting the thing die and putting my $ towards a new system.
Other than that, there may be a circuit that needs to be fixed...but I'm not fancy enough to take that project on.

I have a Technics stereo integrated amplifier SU G75. The cooling fan began making chirping noises then stopped. Now every time I turn the stereo on I get a overload message. Could it be the cooling fan...


It chirped because the bearings were worn out, then it froze up and isn't moving any air. Get it replaced. DO NOT run the unit if it keeps overloading or you will have a bigger problem.

After unit is on several minutes, sound turns to static, crackling noise. Any ideas


I had this same problem, check the power transistors attached to the heat sink near the large caps, they tend to get cold solder joints after lots of heating and cooling. 15 minutes and good soldering iron will probably make a huge difference. I added extra cooling fins to mine to help dissipate the heat. hopefully wont go bad real soon again. Also check the large caps while your in there, maybe a good time.

check the fan, if its dusty clean it then run the player. If it works, your in luck. If the fans are moving and f61 still shows up, the D-amp IC is shortened ( inside you will see IC 5000/IC5200 / IC 5300, these needs to be replaced) its the one by the big cooling fins (behind the rear fan)

F61 error code


Sorry to hear about your error code F61

This code refers to a High Limit Temp. condition.
This is most likely caused by the cooling fan.
If the Fan has stopped running or not running at full speed, you will recv. this error message and the temp. reaches high-end limit.
Please check the cooling fan, any possible air flow restrictions and correct running RPM.

Hope this information has helped you.
Readers, please rate your technicians information.
Thanks,

Loud whirring noise from home theater receiver


Sounds like a cooling fan is worn out. If the warranty has expired, remove the cover and there should be a cooling fan. Remove the fan. Try cleaning it out with a can of compressed air. If this does not work take the fan to best buy or circuit city and buy a replacement. I hopet his solves your problem!

Power will shut down after few minutes when volume reaches 12


If you check at the back of your hi-fi, you'll see a projection at the top where the cooler fan is located. The most likely reason is that your fan is not working (as required). In this system, the fan is turned on automatically at high volumes >=10, because then, the amplifier starts to get a temperature rise and without proper cooling the system might fault.
Try check and see if at these high volumes the fan is running, if not, then that's what needs to be fixed. Alternatively you can try running an external fan to see if it will produce the desired cooling effect.
