Question about Onkyo TX-SV454 Receiver
Hi! I have an Onkyo TX-SV444 A/V Receiver. I have had this receiver for about 12 years.One day I noticed the receiver kept cutting off after about 3 or 4 seconds. After a couple attempts of turning the receiver on, it just quit working. After checking the speaker wires, I noticed 2 wires were touching, which probably lead to the stoppage.I have checked the fuse and it appears to be OK. Others I have talked to said it sounded like the protection circuit has gone bad. Do you know where I could get a new circuit?Thanks, Tim
Hello. If the wires have touched, your amplifier probably has what's known a DC Offset, meaning a damaged amplifier. You will need a qualified audio tech to repair this, as this type of forum is not designed for detailed step by step repair.

The shorted spkr wires probably fried the putput transistors in that channel. Do you know how to use a Fluke test meter on diode test
