Question about Pioneer Audio Players & Recorders
Hello,I have a Pioneer amplifier VSX - D710S ,when I turn the power on it would play ok but it get extremely hot after about 3 songs ,this started for about a week,before this would not get so hot for so quickly,also it would smell like something is burning,please tell me what could be the problem,I did not use it since until I Resolve this problem.I would highly appreciate your expert assistance please help me,I cannot afford to buy a new one right one ,but I could probably get it fixed if it not too expensive.
Heatsinks on mosfets are probably not connected, or broke connection. If you are not trained in electronics dont go poking and proding around in there, a capacitor can easily kill you. If you have some knowledge open it up and see if you see and burnt components etc. You may just need new heatsink grease etc. Does it have a fan that stopped working? If a piece is visually fried take the unit to your local electronic repair shop and see if they can solder in a new part if available. depending on the price of the amp, it would be ebetter to go spend money on a new one.

A precise make and model might yield more-specific answer.
Generally speaking, an amp protects itself from heat, shorts and overloads.
Overloads can be from excessive periods of high output 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 'naked'. 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 hands-on tech.
