Question about Panasonic Technics Sa-gx290 Home Theater Am Fm Stereo Receiver Sagx290
Hi, my Technics SA GX 290 receiver has stoped working. I opened-up the box and confirmed the fuse was OK, not burned. Any ideas on what would be the next steps to identify the root cause of the problem? Any help is apreciated

Most likely if all fuses are good and everything checks out, the something is blown on the circuit board.
In the future it would be best to use a GFCI outlet and a protective power strip, because a power strip for lightning strikes is not fast enough, but the GFCI outlet is and the combination will save sensitive electronics.
I would recommend finding a service man on the website to fix it.

the difference is the "same speaker connections"
the front and rear will connect the same but the subwoofer is amplified by the HT75 , and the HE75 does not have an internal amp for the subwoofer speaker , only a "pre output"(has to be amplified)

The question is, do you hear any sound? Is just the display off or is the entire unit shutdown? Can you tell?
These displays are known to develope poor solder connections at the power input and ground pins. If you can solder, open up the unit (unplugged of course) and examine the pins for the display. This will be on the PC board attached to the front panel. The pins at either end of a long line of pins will be the power and ground pins. Reasolder those pins, taking care not to short the pins together and try the unit once done. If that does not resolve the problem (assuming it is just a display problem), update this with as many details as you can about the behavior of the unit and we'll look further.
