Altec Lansing ACS45.2-Lightning strike

We had a lightning strike near the house that I think came in through the cable. The cable amplifier was fried along with a wireless router and one TV will not turn on. I was using this subwoofer on my main TV that did not get damaged. The trouble is that I can no longer turn the subwoofer on by pressing the two volume buttons. The main fuse in the unit is good and I am getting about 18.7 volts DC after the diodes. Nothing looks cooked. Is there anyway to just install an on/off switch somewhere? Thanks

    After more research on the web I found someone that had the same problem (would not turn on after static shock). He found it to be the volume control IC. He talked about the volume control pins should have a voltage of 12 and his where 1.2 (the same as mine) so I am ordered a new IC. I'll let you know if it works. Thanks for the quick response.

    Did installing the new IC fix your problem?

There is a good chance with a lightening strike that damaged so much of your equipment that this device was also affected. power to the device doesn't necessarily mean that other components were not damaged.... you can elimanate speaker damage by hooking the speakers up to another device to check them.

Is there an adapter/cord (30 Pin to Lightning, or 30 Pin to Bluetooth) actually KNOWN to work with the Altec Lansing iMT800, so we can all charge and control the newer Lightning connector style iPhone

I think your only option is to get one sold in Apple stores. I have a small 30-pin-to-Lightning adapter (not a cable) and it does not work with either my iPad mini or my wife's iPhone 5. I also have a non-Apple Lightning charging cable (as a backup, just in case...). Same deal.

Bosch dishwasher does not turn on following a lightning strike near the house last night

Check your circuit breaker first. If ok suspect control board got fried. If you take it out you may see a burnt spot on it.

When i connect the lan wire my mother board shows lan not connected why/

Either the cable is defective (it has a break inside it so try another one) or the onboard LAN chip was fried by the power surge generated by a lightning strike that came in your vicinity.
That is unfixable, disable the onboard one from the BIOS and install a simple PCI LAN card in its place.

Will not heat baby food for 13 seconds

Depending on the amount of Joules your household/microwave received your low voltage control electronics may have been fried by the lightning strike. For your own safety I recommend a new microwave.

In a nutshell, yes and not only to a Dell but to most computer brands/models. In some instances, it's only the modem, router, LAN card that gets fried while some gets everything toasted.

Incidentally, even a near lightning strike is enough to cause big problems.

Kind regards.
