Hello Sergren, the indication of overload, can come for several reasons
1) The fan motor, outside resistive value is usually between 20 and 30 ohms, to measure it you must disconnect it from the circuit, if it is out of value you must replace it, it is very important that you get the same type of motor or fan assembly
2) The damaged output circuit, you can access the legs of the integrated power circuit RSN3305, taking off the lid that is in the base of the equipment, you must cut the grips that it brings, once the lid is removed, the legs of the integrated circuit are undone and remove it, then test the equipment that does not overload the display, if it does not appear the problem is in the output integrated and you must replace it
Several offers of sale of this integrated appear in Internet, confirms that it is a new and original spare, there are many that offer spare parts of disarmament
I sent you the link to download the SA-EX100 service manual
I hope you can solve the problem

Hola Sergren, la indicaci?n de sobrecarga, puede venir por varios motivos
1)El motor del ventilador, fuera de valor resistivo habitualmente esta entre 20 y 30 ohm, para medirlo debes desconectarlo del circuito, si esta fuera de valor debes reemplazarlo, es muy importante que consigas el mismo tipo de motor o conjunto ventilador
2)El circuito de salida da?ado, puedes acceder a las patas del circuito integrado de potencia RSN3305, sacando la tapa que esta en la base del equipo, debes cortar los agarres que trae, una vez retirada la tapa, desuelda las patas del circuito integrado y ret?ralo, luego prueba el equipo que no se presente sobrecarga en el display, si no aparece el problema esta en el integrado de salida y debes reemplazarlo
Aparecen en Internet varias ofertas de venta de este integrado, confirma que sea un repuesto nuevo y original, hay muchos que ofrecen repuestos de desarme
Te env?o el link para que descargues el manual de servicio del SA-EX100
Espero que puedas resolver el problema
Saludos Franco Dosil

SOURCE: technics sa-ex300 says overload ?
it could be overheating - try aiming a fan at it for a while, see if the problem stops.
SOURCE: I have a Technics SA-AX610 receiver that says overload .
From the manual pg 27....... "The protection circuitry has functioned because the positive and negative speaker connection wires are "shorted," speaker systems with an impedance less than the indicated rated impedance of this unit are used or under severe use, such as loud volume, excessive power and in an excessively hot environment."

I have a Technics SA DA20 control receiver. I was given it by an electronics workshop and it has this same error of OVERLOAD coming into the display when switched on. I removed the plates from underneath and re-soldered as far as I could all the points along the stereo amplifier ICs and as far as access would allow. The unit then worked normally for several hours. I was very pleased, and went out shopping!. But on my return after it had been off for about an hour, the same problem has come back. But my boss at the electornics workshop thinks it it just a dry joint, or series of dry joints. The unit is complex to dismantle, so patience and care is required in taking it apart and making a note or diagram of how it comes to pieces and how to re-assemble it after the board has been re-soldered. It does not appear to be a component problem or fault with the SVI power amplifier ICs.

SOURCE: My Technics AV Control Receiver SA AX530 is in overload
An amplifier should never be turn on without speakers, it will overload internally.
make sure speakers work and try again.
SOURCE: i need help
Loose connection on "POWER-SUPPLY" and sometimes solder loose on "C I S BOARD" due to extreme - heat of amplifier. $137.51 repair done in 1HR as I waited at CENTURY SOUND ELECTRONICS.
