Seem to have been a power surge how can i prevent another one and could i claim through house insurence

It's not the outage that causes the issue, it is the power surge when it goes, often caused by a lightning strike of 100,000 volts, and also a surge when the power comes back on. If it took out one board, it took them all out, because they are all connected together.

Change all the boards, but I bet it still won't work. Claim to your electricity utility company or claim on house insurance.

Likely a power surge hit your house while away. This happens when power turns back on or lightning hits close to your house. If insured, call insurance company about it. You may be covered for replacement or have deductible applied. Small appliances like this are most susceptible to power surge. There is not enough protection designed in.. The best protection is surge module on main breaker panel or buy a protected power strip to protect high value electronics.

claim on the house insurance.

Sounds like a power surge "killed" the circuit boards. Get a professional to check. If the power company was responsible, lodge an insurance claim and get them to pay for the cost to repair the units. A surge will damage electrical components

Here in New Zealand if that happens, I am often asked to provide a report stating that a Surge/Spike, had caused the damage, and the insurance Company will cover it? Can you do that? At least it will lessen costs, I charge for the report, but it's still a cheaper option if you can claim? Power Surges/Spikes usually totally wreck, the electronics... So replacement is only option... You may need a serviceman to check, and if OK write a report for your insurance?

Claim fusion on your insurance policy but dont mention lightning as its an act of God and not claimable in many instances

You will probably be replacing boards left and right with a surge. I would make a claim with the insurance company, it's covered under most home owner's insurance.

Sounds like a power surge. These can ruin delicate equipment. try this, Unplug laptop and remove battery for 30 minutes, Reinstall battery and plug in charger and try to start up. If it works, you're golden, if not prepare to submit an insurance claim on your homeowners policy.

Unplug everything! There is a "breaker" in the power supply and it may need to be reset. Just unplug all cables from the TV and outlets. Let it sit for a couple hours then plug everything back in and it should work fine. If not then the power supply has shorted out due to a strong power surge. You can claim it under your home owners insurance or call Nintendo and try to get it replaced. Thanks! Good luck and happy gaming!!
