Hi diamonddan11

I have posted to your original request for help the details of this. here is a sumary


  1. mains power fuse FU11 is located INSIDE the deck on the same circuit board and the mains on off switch.
  2. There is a thermal fuse that is not changeable inside the widnings of the transformer. This is can be repaired but generally it is considered that you replace the transformer
  3. on the printed circuit board attached to the secondary side of the transformer you will find 5-6 pico fuses, or circuit protectors. The are small black 2 pin devices that are marked on the board as IC901 to IC905
  4. the main power regulator board REGB ASSLY also has a circuit protector IC911.
  5. Thjere are several others in power supply areas marked as IC907, 908, 909, 910, 913, 914.
OK, thats a run down of the fuses in the unit. Non are considered to be user replaceable parts. If the deck has had the wrong mains voltage applied, it is likely that it has blown the primary fuse, FU11. If you do replace that fuse, and the unit still does not work, the transformer may be blown, or any one or combination of the Circuit protector type soldered in fuses may need to be replaced also. If you cannot follow what I have given you here, I suggest you take it to a Pioneer Authorised Service Center.

I am more than happy to answer any other questions you may have about it, just give me a hoy :) If you are still unsure, or have problems, then before you give a rating for this advice, please get back to me and we can try some more things.
Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.

Possible blown fuse inside unit, unplug and remove the top cover
fuse should be near the power board and transformer. replace with exact fuse, "Never remove covers with the unit plugged in" Always wait 4 or 5 minutes after unplugging to remove the cover.Replace cover before plugging unit back in.

So remove the burned out fuse, look at it carefully for the size markings, and bring it along with you when you go shopping for a replacement. But know this: a blown fuse is usually a SYMPTOM, not the PROBLEM. The fuse is there to protect the rest of the circuitry, usually the power supply, wherein the real problem lies. So, if you replace the fuse and it blows again, you've got a much bigger, more expensive problem. Be prepared to pay as much or more to a repair shop than the unit is worth. Be prepared to have a repair shop charge you at least $50 just to diagnose the bigger problem. If you are really lucky,your blown fuse is the result of a power surge (so it did its job or protection). Buy two fuses. Consider junking the unit if the second replacement fuse blows.

Most likely the unit does not receive power from main transformer. Possible several reasons:
- bad power transformer
- bad main internal fuse 7-8amp. Bad fuse most likely because of one of the channel is blown and shorts the power, so before installing new fuse good idea to check all channels by meter or at least visually for burned parts
- bad power relay
- bad connection, cracked soldering joints

No power, doesn't turn on


Try opening up the unit and look for any fuses that may have blown.(they are probably little glass types). Make sure you replace with the same type and rating. If the new fuse blows immediately, then there is a problem in the receiver that will need to be checked by a trained individual. Some possibilities are:Power supply/Amplifier output stage/most any defective circuit can cause a blown fuse

It sounds like you've either cooked the output stage or blown a fuse or two. Some amps use relays to protect speakers whilst others use old fashioned fuses. Check the rear of the amp to see if there are fuse holders. If there are then unplug the unit and check each fuse. If they are marked as mains or power leave that alone it's for the 120volt input. the ones you want are usually marked left and right or just speaker. If the speaker fuses are cooked then make sure you use the same rating when replacing. Also check your speakers, they could be cooked too. Unlikely but possible. Some makers hide the fuses internally which can make things dangerous for anyone poking around. If in doubt leave it to a tech. If the fuses are blown replace them. check your speakers and plug in and swich on. If the fuses blow again go looking for a repair shop as you've possibly blown the output stage.

Sony str-de845 Powers up, relay clicks, fuses BLOW!


This condition, may be produced by defective components (Q506, Q507). you can remove those transistor, replace the fuses, power-on and wait for relays click. if the fuses not blown again, them replace both transistor.

So how do you replace a fuse?


Hmm. Tricky problem. It could be the main fuse blown and the standby power suply is only working. Worts case senerio is that one of your amp is faulty and the unit is in protection mode. If the fuse is dead then you are lucky, just get the cover open, remove the power before hand, and do a little search, Most of the time it will be in a glass tube ( glass cartridge type) rated at 250VAC with a nominal of around 5 to 7 amps rated current. U can check it with DMM in a continuity mode. If fuce blown replace with the same rating and it has to be slow blow type. Cheers
