My daughters leapster 2 freezes and has to be

My 3 year old daughter has a princess leapster 2. Put new batteries in and still will not turn on. I called customer service and they are willing to replace it even after the warranty has expired. Here is the Customer Service #800-701-5327

That sounds bad. I'd check to see if you are within warranty coverage. Sometimes tech support will help you a bit even if you are not.

Most likely, the unit was dropped or else exposed to moisture. If it was dropped, a printed circuit board or similar may have cracked. That's sometimes repairable, but a difficult thing to do even for an expert with good equipment.

On the other hand, possibly a cable or connector inside, particularly one connected to the screen has come a bit loose from being dropped. You might be able to fix that by taking the unit apart (being careful to remember how things fit) and re-seating all the connectors, i.e. disconnect each one and then push it back into place firmly, though not really forcefully. The trouble is that in order to take the unit apart, there will likely be a screw under a label or something similar that is going to break your warranty by opening it. So you probably don't want to do this if the unit is in warranty.

Another possibility is that the unit was exposed to moisture. If so, you can try what I said in the last paragraph but also look for water stains or similar. If you find any, they sometimes leave a residue behind that can cause a short. Sometimes, even a bit of water can last for a long time if trapped under a part or connector. You can clean small water stains with some isopropyl alcohol on a Q-tip. If you think there might still be moisture in the unit, try blowing hard at it while it is open from different angles. You might also try blowing a hair dryer at it and through it for awhile. If it becomes too hot to touch, you have the hair dryer too close.

Warranty repair is by far your best choice. The other techniques may work but unless you specifically spot the problem inside you may not be able to correctly diagnose it and fix it.
