Repair i have pioneer cd player at the shop for repair now and they say that my output ic is blown and my board needs repaired with an estimated cost of not less than $ 250.00 i ask myself are they just trying to get me to buy a new radio from them so im doing a little homework on parts and have found the output ic for 27.00 but my thought is if i bought the board from pioneer would the output ic come installed on the board already hence solving two problems at once. I understand I cant do the repair but if i take the radio and parts to a repair shop around me and just have them put the board in could i or not save myself a little money for im not working with a whole lot I looked on the site for the parts and cannot find the board is it available is my question and your thoughts on my thoughts

    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

  • stevehllsbr Jan 25, 2008

    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

  • stevehllsbr Jan 25, 2008

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 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,
- Jim

    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!

    - Jim

$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.

Pioneer vsx_D710S whatever can be the input source,the flag " poweroff" apears and switch off the system. Seems to have no time rules, shut down frequency connected with hazard ...... No...

I'm not sure what kind of an answer you are looking for. If you are not qualified to do some soldering rework and ready to spend some money (could be as much as 50$) for parts, you better look for a professional service that in most cases will cost as mush (or more) as your receiver.

If you are still reading then here you are. This is a common symptom of a blown hybrid amplifier IC caused by shorting speaker output while it's powered on. There are two protection circuits for amplifier output, Overload and DC output. In your case, most probably, DC output protection is the one that shuts down amplifier to prevent further damage. Find schematics (service manual). To confirm this, look for amplifier inputs connector, measure DC DET. signal, normally it should be around +4.85V. If right after power up it goes down to almost 0V, then it is for sure a blown output on a Hybrid IC. Check whether receiver shuts down with that cable unplugged. If not than get ready to do some rework.

There are two big Hybrid amplifier ICs, one that outputs two channels (usually front left and front right) and 3 channels (for the rest). One of the outputs (if not more) one one of them (if not both) is blown. In most of the 5.1 Pioneer receivers 2 channel IC is PAC010A and 3 channel one is PAC011A. If you want to get original parts and will find those for less then 40$ each you are lucky. There are however cheaper replacements from SANYO, those you can find for around 10-15$.

Find schematics, unsolder resistors one by one that connect AMP outputs to DC detection circuit on each IC and check which one is blown. There are 2 for 2 channel one and 3 for the other. Usually if one output is blown all others on the same IC are blown.

There could be a chance that only one channel on IC is blown, if you want to fix it you still need to replace whole IC. Also, instead of spending on new IC you may want to sacrifice one working channel (center for example) to output the blown one (so you'll get 4.1 :) ).

The first thing that comes to mind is that these units usually use op-amp ICs for buffers on the output lines. These ICs are either defective, or you have lost one of the power supplys. In any case, this is not a simple thing to trace without some test gear. I suggest that you bring this to an audio repair shop. If the ICs are defective, they cost less than $1 each and you will need at least 2.

its the problem in the power supply board of your tv.
check for the fuse on the power supply board.
for any blown capacitors or ics.on the powersupply board.

calling a tech is much advisable.if do not have proper technical knowledge.

it will not be too costly to get it repaired.
it is worth getting it this is a common fault faced by many customers.

Hello I have a Pioneer XC-L11 cd player It no longer plays or reads cds - the display just says that there is no cd in the machine Any ideas?

It is most likely that the laser pick up is bad. That is the part that reads the disc and is the most common reason. You can try a lens cleaning disc to see if it just needs to be cleaned, but if that does not work you will need to take it in for service. This problem can be caused by several different things, from the spindle motor (spins the disc), to the pick up (reads the disc), or even an IC that controls one of those things. Once you have cleaned the lens, you can also try cleaning the disc's. If a disc has a fingerprint or scratch in the area of the disc that is know as the TOC (table of contents), it will not read the disc. Fingerprints in other areas of the disc will cause the player to skip or even stop playing. I use windex and a soft cloth like a bath towel to clean the disc's, it works as good or better than the disc cleaning kits you can purchase, and it is much cheaper.

If none of this helps, it has a problem that only a trained technician can figure out with the proper test equipment. Then you must decide if it is worth getting fixed. Some service centers offer free estimates, but those are the ones that don't actually check your equipment first before giving an estimate. They just give you a ballpark figure that is usually pretty high. To get an acurate estimate you normally have to pay for it. A technicians time is worth money, my shop charges $25 for an estimate.That is pretty cheap. Some are as high as $65 for an estimate. But if you are paying for an estimate, they will normally at least troubleshoot the unit and determain just what the problem is, compared to a free estimate which is just a guess and a ballpark figure usually high to cover the cost no matter what the problem is. You may also end up paying much more for a repair when you get a free estimate, because you have already approved that amount, and many shops will charge you that much even if they find a simple problem that only takes 30 minutes to fix.

Replacing a pick up normally cost about $125 to $150 because the part can sometimes cost as much as $75.

I hope this was helpful for you and lets you make an informed decision. let me know if you need any more help.
