Question about Audio Players & Recorders
Someone gave me thies receive (technics av control amp su-g88 classh+), when i connected the receiver, it says overload, Power off and On. I do it and it still occurs. Before i connected anything, since it was a gift, i opened it n checked the small fuses it had, they were good. Then when i conncted it showed me that, what can I do in reference to that.
SOURCE: Technics SU-G91 OVERLOAD PROBLEM
OVERLOAD means that input signal level is too high. Can you be more specific? From which source you play music when OVERLOAD icon appears?

SOURCE: Overload on Technics SA DA10
This is an old message so you may not be interested any more.
There are a couple of possibilities; the high power of this unit seems to fry speakers fairly often and although they mostly fail 'open,' they can overheat causing the voice coil to lose its insultation and cause a short instead.
This may also be caused by the failure of one or more output modules causing the power supply to limit and give you the overload indication.
If an output module has failed and the unit is not limiting current, it may destroy speakers too.
Some knowledge and a decent meter would reveal the nature of the failure pretty quickly but describing the steps necessary to troubleshoot this is a little beyond the scope of this forum.

An amplifier should never be turn on without speakers, it will overload internally.
make sure speakers work and try again.

The question is what is causing the overload? The power supply or the output devices on the heat sink?
If you have accidently shorted a speaker wire, then the answer will be output devices, otherwise it could be anything in the power section. You may find a burnt or damged device with either of the causes.
