Hi there,

Did you get an exact replacement or a similar adapter?

If the replacement adapter is not the correct polarity and voltage, it will permanently damage the DVR.

I purchased a similar charger.
Electronics Technician: Pete, Electronic Engineer replied 2 years ago

Can you provide a link to the charger so I can check if it is suitable?

If it is not compatible, then it is likely that you have caused some permanent damage to the DVR.

what do you mean a link?
Electronics Technician: Pete, Electronic Engineer replied 2 years ago

A link to a website that shows the charger you obtained;

or let me know the model number if you got it in a local store.

Purchased at Best Buy
Electronics Technician: Pete, Electronic Engineer replied 2 years ago

Ok, the adapter you purchased is rated 19 Volts, however the DVR only uses 12 Volts, so it is likely that the overvoltage has caused some damage.

any idea where I can get my dvr serviced in the Philadelphia area?
Electronics Technician: Pete, Electronic Engineer replied 2 years ago

The DVR will need to be taken to an electronics repair center to check if it is repairable.
