SOURCE: My receiver is in protect mode.

The units in the protect mode because the Microprocessor detects a large current being drawn by the amp. section of the reciver. This is a solid state unit and there are no user replaceable parts inside this unit. Unless you know how to trouble shoot sloid state devices then you should seek a pro to assist you with this repair. GOOD LUCK

SOURCE: Protect Mode

Protect mode with nothing connected indicates an internal problem. Most likely one or more output transistors are shorted. This is a common problem with these and can easily be repaired by a shop for around $35 in parts plus the local labor rate. The output transistors are MN1620 and MP2488 (if memory serves me correctly).

I have had this problem several times with Sony receivers in the past. The issue may be frustrating but these receivers are idiot proof. It is doing you a favor by tripping and not setting your house on fire as well.

Explanation:
Many things like improper wire crossing or touching due to too much of the insulation stripped off can cause this. Thunder storms and power surges as well have been known do this to Sony receivers.

Solution:
Unplug the unit and remove the cover. Look for any blown fuses as sometimes this is the problem. Take the fuse to a Radioshack to find new ones. However, it is likely you will need to take it in for repairs. This usually costs around $100. Find a local electronics repair shop in your area ( "TV Reapir in the yellow pages") or call Sony to send it to them.


I hope the latter works.

My str3000es when turn on the screen show STREAM UNLOCK and PROTECTOR THEN turn off by itself


Check all of your speaker connections at both ends for looseness or any stray wire strands. If they make contact with the chassis, this can and often does cause the electrical short that is making the receiver go in to protect mode. The protect mode prevents electrical damage to the amplifier.

Once you have all of the above verified and fixed, try to power it on again.

How to keep your receiver out of "protect mode" Part I


"Protect mode" as it is indicated by many manufacturers of modern AV receivers, is a useful safety tool but all too common a problem for many people.

There are various causes of this safety feature to be executed, and returning your unit to normal function will also vary by manufacturer by which you will have to refer to it's manual on the procedure. But the following tips to avoid getting into protect mode apply to all manufacturers of all receiver designs and circuit topology

The number one cause of "protect mode" is heat. Receivers that have Solid State amplifier topology produce a lot of heat. Solid State amplifier topology is the most commonly used design in receivers.
To reduce and dissipate this heat that can cause it to enter protect mode; do one or all of the following:

Remove anything stored on top of the unit. Anything that blocks the vents even temporarily while operating will cause it retain more heat.

Give it room, out in the open. Do not operate it while it is sitting in a cabinet or other enclosure.

Store it farther away from any other source of heat; don't overlook things like desk lamps directed at it, etc. It takes only 1 degree higher than the units' internal temperature sensor setting to shut it down.

If you are operating it in a hot climate, try placing a mini-desk fan directed into the vents.

My memory card is saying Write protection every time i put it in my camera. What do i do to fix it? it is not on lock mode because i flipped the switch on it.


The actual switch that detects whether the memory card is in write protect or not inside the camera is probably stuck in the "write protect" position. With a flashlight, inspect the switch in the memory card compartment.

turnit it off complety, unplug, check for speaker cable shorts and then power backup, if it does it still get a service person to look at it, one of the main output power transistors could be faultiy on one of channels amps

Harmon Kardon Citation 22 amplifier is in protect mode


Maybe there's a correlation to those devices being attached. Float the the amp so it has no cables to anything and figure out why it's going into protect mode. If it doesn't, start adding units until it does.

My 450 watt fusion amp is now in ''protect mode''. how can i fix this?


Start by completely turning off the power to it and anything connected to it. Turn all levels down to there lowest volume settings. Check to be sure your speakers are not shorted. Be sure the power voltage is correct. Turn on each of the items, the amp being last. That probably will resolve the problem but I am not that familiar with the unit just trying to help. Most units have stay in protect mode until I cycle the power. Typically they monitor the speaker current hence a short would cause almost an instant protect fault.
Good Luck,

If there is no power at all, then try bypassing surge protector, check power cable, and check if power cord is fused.

If unit has power but does not start, then it is on protection.

Protect mode will kicking whenever a fault is detected.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Regards.
