    please check Q951 volts at collector 12.5v and 5.6 at emitter. if 5.6 volts is blocked, system control IC is not being powered to function. check IC950 if Q951 has no output.

    Let me know results to proceed further.

My Sony receiver amplifier model number Str-de315 has just stopped working clicks on 2 lights come on but nothing else k


no front panel display means one of twot hings: either the power transformer is blown, or the main power fuse. If the main power fuse is blown, then there are likely to be shorted output transistors that will need to be replaced.

Sony STR-DE575 connected to 220V


Doubt the main pcb needs replacing, but the standby transformer would definitely go in that situation. Standby transformer wouldn't be that expensive, but no way to say that it's the only thing that is bad. It is also soldered in, so you would need to know how to do that to replace it, or bring it to someone who could. If you're staying long-term in Europe, it might just be better to buy something local so as to not run into this problem again.

My Sony Receiver Model No STR- DE315 Stuck on standby soon as switches on ,Anyway can assist...


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Worked perfecutly but wont power up after a power outage. What do you think is wrong. Bass bost and hall lights come on.


The power supply is bad. Check for open fuses. If fuses are good, then the voltage regulator in the power supply may have damaged.

If the reciever gets real hot would that cause it to go in protect mode? Sony str-de315

Unless its being played to loud with to many speakers connected!

STR de315 shows 'protection' after 10 minutes. Is this a common issue?


Does it still do this if the speaker wires are disconnected? The amp is protecting itself from a short on the output. maybe yo have a dead or distorted driver in one of the speakers. Also there could be a defect in on of the amp circuits.

Pioneer SX-203 power transformer ATS1526 secondary voltage???


just a question.1st.. if you don't know what you should have... then what are you going to do... if it's lower or higher ... seems like you should have a print before you go looking...go check at the off and on switch for the standby .. 9v more or less to trip the relay to turn the sys. on... now get a print...or go backwards to the transformer to see if it's blown. or something in between is open

You probably have shorted rectifiers and/or transistor(s) on standby board. Trouble-shoot rect bridge and cap. Feel stand by circuit transformer for abnormal heat, sure sign
