Have TV Questions? Ask a TV Technician
Hello and sorry you're having problems. We cannot locate anything using the serial number off the back of the TV, but that's okay. JVC only made two sizes that used an external power supply adapter- a 32" and a 37" both used the same one. It's a 19 volt DC switchmode supply, using standard 2.1mm barrel plug for the TV inlet, and it can be purchased at the link below:

Alternatively a universal Laptop power supply adapter (available from Staples, Best Buy or even WalMart) can be purchased in a store- set to the 19 volt setting (they have a selectable switch) and used with this TV. They are all at least 3 amp rating, which will work fine for the TV's backlight circuit and be usable with the set.
If you need further assistance let me know. Please do not forget to click at least a 3 STAR RATING, at the top of the page for my efforts. You can follow up at any time if needed.
