What part of FAN ERROR implies an external reason? The FAN is implicated.

A web search for "STR-DA30ES fan error" leads to lots of owner input.

For example:

and the Service Manual (same search)

How do i get my sony DA30ES am -fm reciever out of protector mode
I have a Sony DA30ES - 18 years old now (legal age to smoke knock on wood) and started getting clicking, popping, static and other noise that I could whack out of it for a time but recently started getting 'Protect Mode' and no audio.

I gave it a visual inspection and although dusty inside, no broken fuses, bad solder joints, loose pins/ICs or bloated caps. So I was thinking replacing caps due to the age but after fiddling with it and trying to narrow faulty caps I realized there's a BLACK RUBBER CUBE glued to the bottom of the Main Board accessible when unscrewing the bottom plate. When pressing up on this Rubber Cube the receiver would work no problem. So I think the rubber cube has decayed/shrunk (18 years).

I added cut to size sticky foam pieces (from command strips) directly to the cube to prop-up this section of the Main Board with the bottom plate closed and problem solved. Leave it to Sony to build a superior product 18 years ago that still works beautifully today. Sony's high end products only fail due to rubber belts (walkmans) and pieces like this rubber support cube. Thank you Nihon ES Engineers! ?? ??

Da30es protector error just scrows on the display
Disconnect all speaker wires at the receiver and power the unit back up. If it stays on, reconnect speakers2.gif one by one and test each time. You will either self correct the problem, (usually a braid or two touching the other terminal) or you will find the speaker or wire with the short. Once you find the speaker that's causing the problem, disconnect the wire at the speaker and test again. Be careful and keep the wires separated so they do not touch. If it still cuts out, replace the wire. If it stays on, your wire is good and the problem is in the speaker. For good measure, reconnect the wire to the speaker again careful not to have braids touch each other and test. If it still cuts out, meter the speaker on resistance to check for a dead short which is caused by a bad voice coil or bad crossover. If your not proficient with a meter, take the speaker to any home audio2.gif shop and have them test it for you. Most will do this free of charge. If you disconnect all the speaker wires and the receiver still goes into protection, it will need to be serviced. Once serviced or replaced, be cautious when reconnecting speaker wires and test the same way. 80-90% of the "protection" cases that I service are do to a shorted wire or speaker. Hope this helps

Computer won't turn on won't do anything , i had it connected and someone at my house was using electric drills and the fuse tripped and everything was shut down including my computer and since then it...
Try unplugging the computer completely from the wall for 15 minutes. Plug it back in, and see if it will power on.

If it doesn't it's most likely a blown power supply, when the breaker tripped, everything on the circuit basically fed back into everything plugged in. This is something most computer power supplies do NOT like.
The good news is, a power supply is generally pretty cheap, you can get new power supplies atarting around 20 bucks, although decent quality ones are closer to 50 bucks. Bad news is, there is about a 1 in 20 chance the power supply took other parts with it.
Once you do get it running, or get another computer, make sure to get a surge protector strip and plug everything connected to the computer into the surge protector. A 15 dollar surge protector can save you 150 dollars in parts and labor. (or more)

JVC TH-C30 Digital Theater System
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.

I have model GE Microwave serial # JVM2070SK02. I start to cook something and it shuts off 5~10 seconds. Keyboard is still lit up, but no clock, fan, light and you cannot operate anything on the key pad. Unplug the unit and it resets. Sometimes it cooks, sometimes it doesn't? It is getting more frequent with the shutting down problem?

Sony projection big screen
does the led flash when you try to power it up? If so let me know the number of flashes. From your description I would suggest 1 of 2 things happened. (1) The Convergence amp ICs have shorted and blown the 5 amp fuse on the G board, or (2) the red CRT has shorted shutting the set down. Check the fuse and if blown replace the fuse and disconnect the Red CRT PC board from the RED CRT and try powering up the set. If it powers up without shutting down then unplug the set and rehook the RED crt pc board and try again if it shuts down the reds shorted. But if it still wont start with the CRT unhooked or blows the fuse Change the Convergence ICs

Protector flashing
Protet mode is a special diagnostic mode that starts when a fault is detected.

When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.

Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.

Try unplugging power cable for one hour or so. then connect cable back and see if you get rid of protect state. Sometimes accumulation of electrostatic charges inside circuit capacitors can kick in protect mode. In that case unplugging the unit from main for some times can get rid of electrostatic charges, and reset circuits by draining power completely.
If that was the problem, you will not get Protect when plugging back power cable.

If you do all the above and still get Protect, then there is a real fault.

In that case the unit may be disassembled and tested to find the fault.

If that is the case I suggest contacting the manufacturer at the number listed on the owners manual, or asking a quote on repair to a local technician.
