The output IC is probably mounted (and soldered) to the main board and the IC typically has a metal tab on it that is bolted to the player's metal chassis or a metal block on the board to help with power dissipation (heat).
Maybe you misinterpreted that there was a board problem as well. It's true, the board needs repaired but they might have been referring that the IC needs to be replaced on the board.
$250.00 seems steep to me. Who is to say that they will really replace the entire board and not just replace the IC? The only way to know for sure is to demand the old board back. After all, it's yours....you paid for it.
Replacing the output IC is not that difficult.
1. Requires mechanical knowledge to take the player apart and put it back together.
2. Requires knowledge to be able to unsolder the old part and install the new part (don't forget the heatsink compound grease!)
You will save money by buying the defective part and having it replaced by a professional. Your biggest bill will be the labor since you already bought the part and bypassed any markup on the pricing. Hopefully that is all that is wrong with it. You didn't mention the symptoms - like no sound.
Good Luck,

Hi Steve,
The part is most likely soldered in with its metal tab bolted to some piece of metal. The faint, distorted sound that you are hearing is probably just audio coupling through the bad part from the audio driver (stage before the final output).
If you plan to unsolder the part yourself, get some SOLDERWICK. It comes in a spool. Just lay it on the solder joint and apply the iron. It will wick up the solder and help you with the unsoldering part. When you go to put the new part in, make sure you put it in the same way it came out. Maybe take a picture of it before you take it out. When you go to solder it back in, use just enough solder to make the connection. Also don't leave the iron too long on the solder joint as the heat can damage the new part. One last thing: When you take out the old part, look to see if there is white grease on the back of the tab of the old part. If so, you will want to apply some new grease (heatsink or thermal compound) to the new part. Some parts dont use grease, they may use a mica insulator or rubber-type insulator. Make sure you use these on the new part. On some devices, the metal tab may not be ground and if you don't replace the insulator, you'll be shorting out +DC to the chassis ground.
I used to own a store front repair shop back in the late 90's and people were always bringing in stuff that had been looked at before and had been given high repair estimates. I know these places have expenses to cover but getting a bad reputation doesn't help you in the long run when no one will come to you anymore and they tell others their bad experience.
Good luck with the repair. Let me know how it went and who knows? Maybe you'll be the next Pioneer Expert on here!

$250 is a bit tough if you are sure the IC is only $27. It is not clear from your post if your microprocessor works alright. If your display and other functions were okay when you gave it to the service guys, your micro is okay, in that case the only other costly thing in your board is output ic. Getting a board from Pioneer isn't easy, they don't sell boards in shops, they provide it to their authorized service ceneters only. You can try finding a friend who is aware of the boards and have this checked.

All other functions worked on radio just no output i think there might be a good chance that my board needing repaired my be a good way for a repair shop to charge you more for a repair considering the part that needed fixed is only 27.00 and the cost of the part is accurtate i looked it up on the net do you know if replacing the output ic is something someone with no electronic background could do like unplug and plug in or is it more like sodering something
your correct i didnt mention sympton but the sympton is no sound actually there is sound when it is ran through my rca cables through an amplifier there is sound but faint and distorted i think that i will pick up player and try repair myself ive already had it completly apart and back together just didnt see anything obvisious wrong so i dropped it off to them the parts are only 27.00 and really thats a small amount to loose if it doesnt fix problem for me so i believe ill purchase the part and play a little
thanks for all the insight and when i get the part and things infront of me ill probably call you guys back
thanks again steve
it want take a cd or play it
