Question about Audio & Video Receivers
My receiver blows fuse immediately when switched on.
What fuse are you blowing? A fuse in the amp itself, or the fuse in your main fuse box for the house?
If it's the one in the amp, check the speaker wires for shorts, and if thats not it, then it is bad news as stated above.
If it's youre home fuse thats tripping, then you need to consult an electrician to give you another ciruit for your setup. Possible the TV is draining a lot of power.

I cannot seem to find any useful information for so I'll just say this from personal experiences repairing amps/receivers. Unfortuneatley there is no good news for you.
The only reason a fuse would keep blowing is if a upstream component is bad or there is a short to ground on the circuit card. If g5500 is a tube set you may get lucky as tubes either open circuit or short circuit. My suggestion, if tube, would be to power up the unit after taking the cover off and notice if there are any tubes that light up at all, will be a quick look and a number of fuses.
BUT FIRST. BEFORE YOU TAKE THE COVER OFF ANY UNIT, UNPLUG FROM WALL AND LET IT SIT FOR 2 HOURS. This gives the unit time to discharge the large capacitors in the power supply. After you wait, then take cover off being very carefull. Notice where there are capacitors (look like miniature coke cans) or any other component, you really want to avoid touching anything, And talking about touchingif you touch a tube wash your hand real well or preferably wear gloves. The oil from our skin will cause the tube to bust because of the interaction.
Another thing you can do is follow the above procedure to remove the cover but don't turn on the power.Carefully remove all the tubes. The unit might "power on" but can't be used. This would indicate one of the tubes is bad. If it does shut-down immediately, shop time.
Pure new-age component only amps/receivers are a lot harder to diagnose as there is solder work involved to test the individual part. So this need to be done in a shop as well.
I would love to help but can't, I can only guide you a bit.
