Item not working properly


Is there an official or unofficial time frame for reporting a purchased item is not working properly

I am actually the seller, and it (a used, maybe 3 year old player) was working perfectly before shipping. I do not anticipate any problems, but was wondering about the issue.
I guess I'm in  the minority here.  I have sold hundreds and hundreds of pieces of gear.  I usually will give maybe 5-7 days after receipt.

2 weeks is a lot of time for something to happen that's out of my control.  Roommates, wife, kids, maids, pets.  Power surges, brown outs, lightening strikes.

I've only had 2 such instances and after the buyer calmed down and started to investigate the actual details, it was found that someone/something on their end caused the problem.
Was the item working during the 2-weeks in his possession, if so, it just bad luck for the buyer as this is the risk you accept when buying used.  .

brf...very well said.  Totally agree.
I very recently experienced an annoying intermittent muting problem with a Japanese preamp purchased through this site.  Had a high end salesman friend check it out and no, it was not my clumsiness with the volume/mute control.  Contacted the dealer/seller within 3 weeks of receiving the unit (who indicated he had not checked the unit out as it came from a "trusted" consignee) and he directed me to repair services with advice that repairs were on him.

Needless to say after lengthy testing & analysis, various attempts to import non existent parts from The Land of the Rising Sun, multiple phone calls and emails to importer, repair station, seller, etc, etc, etc, the seller, a really treacherous swine, offers to trade in the damaged unit on a $20K amplifier, but he'll let me kiss his behind for the $300 repair.  Both Audiogon & Paypal say they can't help as "time has run".  

My advice: get EVERYTHING in writing. Verbal promises are factually worthless. Return any defective item immediately regardless of seller's promises. Now I've got to sue this !!*&%!!@ dealer in Small Claims Court... and that's going to be a real pleasure.

Update; After no contact for another month, the buyer finally called the manufacturer as I originally suggested. He now wants me to pay for the repair or refund. It is 9 weeks since the sale.  He did not want to contact the shipper. Thoughts?
Tell ’em to go pound salt ! 9 weeks and he has done nothing, sounds like you are dealing with a real deadbeat !!
