The unit won't switch on.It keeps going into standby

Hi,
There are 3 possible reason for this problem:-
(A). Solder points are distorted or no longer contact the CPU (and/or the GPU) to the motherboard
(B). Your hard drive could be loosely connected or became unconnected
(C). Your power cord is spent

Here is what you should do:

1. If it's still under Purchase Warrenty, send it to Sony for free. You can request your free service at this link and click on Support.

2. Unplug the ps3. Remove the small HDD cover and undo the Blue screw. Lift up the wire tab and slide the HDD towards the front of the system to dismount it. Careful not to pull / push too hard as it may smack the side of the inner-wall when it comes loose, though it would take a pretty hard impact to damage the ps3 hard drive. Pull it out and blow all the dust out of it. Slide it back in and put the Blue screw back in. Try now.

3. Call your local GameStop and ask if they have any Used Power cords. If they do, take your ps3 with you and leave it in the car, walk in to the shop and ask them if it's okay to bring it into the shop to test the Used Power Cord. If they say okay, give it a shot and that's a possible $20 fix.

4. Look up your local business directory and look for a video game hobby shop (a very generic way to describe the shops) as a lot of them will repair your system locally, MUCH faster, won't FORMAT your hard drive! and for less than HALF the price Sony would charge! Better yet, this money is "locally spent" so it would help your local economy much more then Sony would :)

5. If you're experienced with repairing electronics you could attempt it yourself as there's only 1 challenging step, and the rest is just time-consuming. (not recommended!)

6. If all else fails, www.us.playstation.com and click support... request service... describe the problem... send them $180. They will mail you a plain carboard looking box with instructions and all packaging essentials. You would then need to take it to a local UPS store to ship it off to sony (prepaid in the $180), and wait for it to come back to your house. They will either repair or replace your system and will not tell you which it'll be til you get the receipt back with your system.
Good Luck and have a nice day.
rating the solution is highly appreciated.
