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.

When the unit is pluged in an the power switch is on there is no power to the unit. Anyone help?


Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

No power, system is 4 years old. un pluged system and moved to another plug but still no power


You can open up the unit and check the fuses. Replace them if they are blown. If there not blown then there could be loose wiring. If there is alot of dust build up, take care of it with some dust off.

On pluging on the main AC pluf, there is not


do you have the cord plugged into the computer? is there a switch on the back near the power supply? if so, is it on? is the large connector from the power supply tightly latched to the mother board? (unplug the computer before you check this!) any fans running? plug a lamp into the outlet and see if it has power! could be a popped breaker, or blown fuse.if you feel confident of your skill, remove the power supply, open it up and see if it has a fuse that may be blown. if so, replace it with a fuse of the same type (size & amperage). if the fuse was blown, and you re-install the power supply and it blows again, then you have a problem (probably) with the power supply, and if cost effective, it needs replacing! get a compatible power supply with a higher power rating, if you can! more power for your peripherals!
good luck!

Recently i had a power surge and my copier machine was pluged up now it does not come on or work


Sounds as though a fuse has blown. Unfortunately, this will be inside the unit to protect the power supply and other electronics.

be sure all units are auto volt. if you plug units 110V to 220V it might be damage or fuse will blown up.

Next best guess is the larger filter capacitors in the power supply are bad and shorted out, you can check with an ohm meter across capacitor leads (with power unplugged)

Power problem.


1. Make sure the AC outlet is good.
2. Make sure there is no damage to the AC line cord.

3. Look to see if there is a fuse at the rear of the unit. It's usually located inside a black circular housing with a screw off cap that says "fuse".

If not, unplug the unit and remove the outside cover. Look for a blown fuse on the motherboard or power supply. Replace it with the EXACT value of the original fuse. You can purchase a new fuse at Radio Shack or hardware store or auto parts store. Try powering up the unit again and see if it works now or whether the fuse blows again. If it blows again, the power supply may have been damaged.

Please let me know if I can be of further assistance to you.

Good luck!
