It is unlikely that the display itself is faulty although it can happen. The typical problem is either the backlight is defective or the suply to the unit has a bad connection. If you can solder, try resoldering the pins on the display itself. The pins on the ends are the power and ground. I don't recall whether or not your model has a separate back light bulb or not. That too could be burned. Chack for that too.

Keep us posted,
Dan

Heat?


Generally speaking, an amp protects itself from heat, shorts and overloads 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 '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 and competent hands-on tech.


Check for loose speaker connections as a root cause for intermittent shutdown.

Technics receiver SA AX540 overheating


is the fan turning on? many models like these have a cooling system (fan) that kicks up when the volume is turned to a certain level. if your fan has never been on, then chances are some of your soldering points have shifted or gotten a little messed up over time from the heating/cooling effect. this model runs extremely hot especially right where the vent is on the top of the cabinet. make sure that it is not in a shelf or enclosed area. dont stack other items on top of it. use an external device to control the volume so that you can have the receiver volume at a fixed level where the fan will turn on. if your sound still doesnt work, you should consider buying a new receiver or try your local craigslists forum. make sure if you buy a new one, that it is a more expensive model from a brand like sony and check the model online for known problems. stores like best buy offer extended warranties on most of their products which are very wise investments. good luck sinbad
