When I hit power button nothing lights up but I hear the subwoofer power on but still no sound. It's as if it wasn't getting power.


Try disconnecting everything from the back of the system and unplugging it form the wall for a couple of minutes. Plug it back in and try poering it on. You may google search "diagnostics boot" or "error boot" with you model number and see what comes up. There is a fuce inside you could check, usually to the back right on Yamaha receivers. This doesn't sound likely due to your subwoofer sound though....maybe.
I bought about 70 receivers that were last years models from Yamaha, Denon, Sony Bravia, etc. Most worked but some required fixing. Some where easy as fuses, blown capacitors (visually), then some are still in my storage LOL. I hope this helps. By the wy, you can always purchase a repair/diagnostics manual that repair shops use with diagrams and trouble shooting tips for your particular model.

GOoD luck

I would suggest a quick resoldering of the flatcable connectors, both on the display board as well as on the main board. That should fix the problem.

The unit does not work


check the standby power supply first and then the main power supply.also check the output transistors and fuses your problem is in one of those points, normally the standby transformer goes bad, it is the small one right next to the big one.
good luck

Reciever shut off AND WILL NOT TURN BACK ON


Sounds like it could be a major problem. But...It could be as simple as a fuse.

Do you know how to use an Ohm Meter or a Multi Meter??

If not, there is still something you can check, if you feel comfortable taking the thing apart.

1. Power it down.
2. Open it up, and look for blown fuses.
3. You can't always tell by looking...especially if the are "Slow-Blow" fuses.
4. If you know how to use a multi meter, you can check the fuses in place.
4a. You have to turn it on.
4b. Put your multi meter on VAC. Put the probes on both sides of a fuse. If you measure no voltage the fuse is good. If it measures voltage, the fuse is bad. (I know it sounds backwards, but a meter only measures the difference between voltages, and a good fuse will have the same voltage on both sides, hence no voltage)
4c. Replace bad fuses.

5. If you are uncomfortable with the powered on method, you can remove the fuses, ONE AT A TIME, (so you don't get confused...no pun intended), with POWER OFF. A fuse puller is a useful tool. If you don't have one, BE CAREFUL!
5a. Put your multi meter on Ohms. Measure resistance across the fuses. If resistance is real low (like less than 4 ohms), the fuses are good. If the resistance is high (like 1k to infinity), the fuse is bad.

I hope this helps.

Good Luck!

HTR-5550 will shut-off after an hour of operation


Hi Guillot

I would be checking about the regulator and power output stages for dry solder joints. With the progressive heating of the unit from operation, failing solder joints may be causing a condition to occur that operates the protection circuit. Careful inspection under good light is required. You may find soldering around outputs, drivers and other devices mounted on heat sinks or other devices that run hot to have circular fractures in the solder about the lead to be commonly responsible for the problems you are facing., if you have a soldering suitable iron, and the time and patience, go for it. I have included a link to a soldering guide here.

Good luck, thanks for using FixYa, and a rating of FixYa would be great for my time to address your problem. Cheers

regards
