More than once. It got the dreaded Disc Read Error problem, so we sent it off to Sony. Took about 3-4 weeks to get it back, and it worked... For a couple of weeks, when the DREs returned. Another 3-4 weeks later, and it was fixed for yet just another couple of weeks. I can't remember if we set it out a 3rd time or not, but if we did, it also broke yet again, because it's currently buried in my brother's room somewhere still not working properly. Eventually we got a slim PS2, which needed to get its power brick swapped out because the power bricks Sony shipped with the first run of slim PS2s had a minor defect where they might just catch on fire. Aweeeeeeesome. >_<
Combine that with the problems I had with my 60GB PS3* and relatively close to launch PSP Go**, and I will never trust a Sony product at launch again.
*Blu-ray laser died, so I couldn't play PS3 games; I did play PS1 games on it until the coffin arrived though. after that, it became more and more of a noise maker and space heater every time I turned it on, and fearing a possible YLoD and losing all my copy-protected saves, I got a slim PS3 (which had been out about 5-6 months at this point) so I could do the data transfer utility to keep all my shit (which finally worked after multiple failed attempts because the utility would just freeze at around 90%. took the better half of a day just to transfer some save files and DLC, thanks Sony.).
**Screen didn't work out of the box, then it came back and worked for about a day, then died again. And they didn't have the web repair request form set up for PSP Gos yet, so I had to deal with a customer service rep on the phone who kept questioning my model number. "It's N#####." "2000 or 3000?" "No, it's N####, it's a PSP Go." "...So a 3000?" "IT IS A PSP GO!" "Oh, it's a PSP Go. Okay. Why didn't you say that earlier?" ...
