Question about Onkyo TX-8511 Receiver

1 Answer

Power up problem

For no apparent reason (no lightening storms or abusive children in the house) the front panel of my TX-8511 will no longer light up with any indicators other than a dim red dot indicating power on, I think.

If this were my old Harman Kardon amp, I would check the fuses but there is no external fuse protection that I can see. No combination of front panel buttons seems to change anything.

Try powering the unit right down by disconnecting from the mains supply. fire up after 5 mins and see what happens. There is a separate transfomer for the standby supply(small red light) An internal fuse may have failed or the thermal fuse inside the transformer. If fuses blow as sson as you fire up = output transistors hay be short circuit.

Why won't my TV turn on after a storm?

Your TV might very easily be destroyed now, from lightening damage. Lightening can come in on the cable, on the power line, all sorts of unexpected ways. I've personally been struck by lightening, plenty hard enough to destroy almost any electronic device... and I was working in a basement at the time.

You can't blame any component in the TV failing after lightening storms. Get lightening arrestors on the antenna cable and use a surge protector on the power cord before you replace the power board again.

I have a 2008 Toshiba tv 40RV525U model. We had a thunder/lightening storm. The power to the whole house did a on/off/on flicker. Now my tv only has a flashing power light (green). Does this mean my tv is...

The power source of the tv has been fried by the power surge and it must be replaced, the damage is surely to great to fix it. Pray to all your gods that the damage is limited only to the power source, otherwise the tv is truly dead.
Call a tv repairman, there's nothing more you can do.
And next time when you have a storm unplug everything with electronics in the house, from every wire.

Powered Or Unpowered Subwoofers For Onkyo TX-8511

Greg- Powered subs are better than non-powered subs (also known as passive subs), anyway I see the TX-8511 has no sub pre-out on the back panel, so you need to decide what sub you will use and run from the receivers left and right speakers output into a subwoofers speaker in from speakers then back out to speakers, look at the back of a subwoofer and you will see like 4 sets of speaker hookups 2 in and 2 out, what this does is takes the low end or bass and drops the signal to the subwoofer then takes the mids and highs out to your left and right speakers, unless your regular left and right stereo speakers have large woofers a sub is the way to go.
