Hi, on my Sony STR-DE935, Fuse #801 keeps blowing.Is it caused by a shorted bridge rectifier or one of the voltagr regulators, or am I looking in the wrong direction? Thanks, Ed Knight

    Hi Johnwdarts,

    Thank you for the information as you were correct in saying that the problem could be on of the MP1620 or MN2488 transistors. After doing a continuity check on these components, I found one of the MP1620 transistors to be shorted! It has been many years since I have done bench work and it was fun solving this problem with you advice.

    Thanks again,

    Ed

Ed,

It could be one of those but most likely it is a set of shorted output transistors. MP1620 MN2488 in most sony receivers.

SONY RECEIVER MODEL STR - D315 keeps blowing a fuse


When the main fuse blows on a sony, it is usually caused by shorted output transistors. You would have to replace these transistors before the unit will not blow the fuse and power up correctly.

Turn on the unit the 120v 6amp fuse blows right away


Hi,
This is an indication that you have a short on 1. Power cord - even low of chances but still to be checked. 2. Rectifier Diode 3. Transformer 4. Voltage regulator IC/transistor 5. Main filter Capacitor.

This is not DIY and can't be fixed without some test instrument so I've advice you to look a technician to isolate the shorted parts.
Hope it may help you.

Have a Sony STR-DE635 that keeps blowing the 2 8 amp fuses in the power supply. disconnected all speakers and powered up with same result. Checked bridge rectifier and (2) 10000 uf caps all are good


Have you checked the rails to ground for shorts. Get hold of a variac as it does make things a lot easier.

Sound like you might have some shorted output devices.

Hope this helps

I got to replace 2 fuses from a sound board of a reciever Sony STR-DE935 but I lost the old one and now I don't Know how many Amp and volts should I buy to replace it .where I can get it?


If its the sound board both fuses are the same. but if they blew you may have a bigger problem like output transistors shorted. But try replacing fuses first if they blow again thats your problem. Good luck

Sounds like a bad solder connection. check around input jacks and tighten the screws that hold the circuit boards and the heat sink.

Fuse keep blowing off


If the fuse keeps blowing, that is an indication that something has failed and is drawing too much current. Most likely it could be a problem with the power supply, such as a shorted rectifier diode or voltage regulator. Another possibility could be a shorted audio output module. Unfortunately, you'll have to take it to a repair center to be serviced.

Please let me know if I can help you further.

Good luck!
