SOURCE: Overload on Technics SA DA10

This is an old message so you may not be interested any more.
There are a couple of possibilities; the high power of this unit seems to fry speakers fairly often and although they mostly fail 'open,' they can overheat causing the voice coil to lose its insultation and cause a short instead.

This may also be caused by the failure of one or more output modules causing the power supply to limit and give you the overload indication.
If an output module has failed and the unit is not limiting current, it may destroy speakers too.

Some knowledge and a decent meter would reveal the nature of the failure pretty quickly but describing the steps necessary to troubleshoot this is a little beyond the scope of this forum.

SOURCE: receiver says power overload, turn system off

It probably needs soldering of the voltage regulators and/or output IC.
I think that model has an access panel on the bottom (it may need to be cut out then rotated and screwed back on when done).
If it doesn't have the panel the main circuit board needs to be taken out to access them.
The regulators and output IC are mounted on the main heat sink. a little soldering and it should be good as new.

SOURCE: Overload on Technics SA DA10

Cracked solder joints due to excessive heat cycling. Do not place in a shelf system. Top MUST be open for 1 ft. or better for proper convective cooling effect. Mine suffered same fate but repaired locally.

WHY DOES MY RECIEVER KEEP BLOWN FUSES WHEN I TURN THE POWER ON?


Fuses blow when there is an overload. The cause being a shorted semi-conductor that is acting as if it was a piece of wire.
Nine times out of ten it's the main power amp devices located on the heat sink that have gone. Often caused by faulty speaker wires, or wires touching each other, so check all your speakers and cables for faults, after you have fixed it!

My remote doesn't even turn the reciever on anymore. It has new batteries.. the red light turns on. If I manually turn the reciever on and press any button on the remote the display in the reciever...


A make and model number might be helpful.

If I understand you, nothing makes the receiver come on. Is there a reason you emphasize or suspect the remote when the hard-wired power switch doesn't work either?

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Eure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

I have a Westinghouse LTV-32w1. The inverter is lighting the backlights for only a split second. Screen is still visible under an external light. The board is getting and holding it's 24 volts from the...


16 transistors did not go bad at the same time, of course. The inverter's driver IC has an overload sense circuit which causes the inverter to turn off.

There are too many possible reasons why an overload can happen and half of them do not involve shorted components.

Your easiest solution would be to replace the inverter. Unless you want to get into the repair business it might as well be the cheapest one.

Hope this helps.

My monitor showes for a split second then goes black


First, can you attach another monitor to the computer to check to see if it works?

If it does, then your monitor is going bad. Possibly the power supply.
If a second monitor acts the same way, then it's your video card.

AVR-745 Firmware upgrade


I have done an update in the past/ ONE Thing/ you do not attempt to do an update at the same time you download the firmware update.
You always download the update/ Open/ Read the instruction and follow them as directed.
An Yes/ it is possible that you might be doomed/ but I would go back/ Download the update with out being connected to the reciever/ Open the download/ Make a folder for it to uncompresse to. Choose that folder when prompted as to where it is sent when uncompressing.
Then go to that folder and READ EVERYTHING FIRST. There is a folder in there that is named to read first.
Once you have read it/ you will see that it is easy to do/ and see your mistake.
I believe that if you try it again, (even though your reciever info is screwed up) it will take the full update.
Sorry about the caps/ I am not trying to yell or what every they say about caps. It just is really important to read everything first. If you don't think you understand what you read/ Read it untill you do understand it. Do more research until you do.

Denon avr-886 VERY FRUSTRATED


Read the manual. You've either got crossed speaker wires, it's overheating, or it's a more serious problem. The same just started happening to mine, so I'm taking it in.

It just starts and stops after few seconds ...


It sounds like either the compressor is bad, or the overload and relay assembly mounted to the compressor is bad. The easiest way to determine which is to put an amp meter on the power wire to the compressor assembly. It should only read a few amps while running. If it reads excessive amperage, you have a bad compressor. If you do not have an amp meter, then you could just go get a start relay and overload from a parts store and try changing those parts, as they are much cheaper and eaiser than changing the compressor....just unplug it before messinfg around inside the overload cover on the side of the compressor! Good Luck!
