I need to break my ps3 and make it look like a accident please help.

More info Below

Ok so, I got the YLOD and sent my ps3 in to be repaired thru a waranty by toys r us, i got it back
and its broke again, i dont want to do this every time, i have only had it back 2 weeks, i heard that places that do repair work dont use sony approved replacment parts, IDK if thats true or what but, i just dont trust they will repair it to full working order, and that it will just break again. however my warranty does cover "Accidental Damage from Handling" and when i bought the warranty the manager sold it as "no questions asked" saying if something happend no matter what they will fix it.
so basically im looking for ways to break it beyond repair so i can get my money back and buy a new PS3.

I was considering the pooring soda inside of it while unpluged and saying i spilt it, or something like that think that will work? please help
my main concern is that i will send it in and get back only to have it break again. im looking to do enough damage so that they wont bother to repair and will instead replace

I have had my PS3 since 2007 when it first came out (60GB model) and has been great for the past 2 years and a bit up till just over a week ago…

First off started with disc reading problems and it needed to have its disc reader laser replaced (sorry am not very technical with names) and i gave it in to the retailer i bought it from because i had extended warranty for 3 years thank god and they sent it off for repairs somewhere down in essex to professionals who fix sony equipment for a living (so i was told).

So then i got it back yesterday(less than a week later) and they told me they did replace the thing i thort it would be, first problem i noticed when i opened the box is it was covered completely in like a very mild saw dust inside and out of the console (even in the hardrive which i took out today to check) which is my first question whats all that about since there wasent anything in the box itself? was just foam to protect it and the cardboard box itself!

Second problem was switching the console on literally worked for like a minute before the screen froze and became completely useless, switched it on and off again (had to be switched off at the main power switch at the back because the power button on the front wouldent work) when i switched it back on the power button at the front still wouldent work and now the bluetooth lights on the front either dont come on at all or flicker like mad when the screen instantly freezes again and wont recognize my ps pads at all even when i plug them in via usb and its been like this for 12 hours now nothing will work!

just wondering if anyone else has had the same problem here and what they ended up doing? any compensation for an irreplaceable console? or give me my money back? i dont want a tade in since i spent £450 on this and any console they give me now i’m loosing money and as for repairs i have lost all faith.

My retailer is comet btw and before i sent it off for repairs EVERYTHING worked on it fine except for the laser reader and if anyone works in retail would be great for some sure win tips *thumbs up*

thanks in advance!
