ok how long you brought the ups and how long you had not start the the ups usaully ups is power dead change the battery and try to power up it should work be sure that all connection is connect properly before power up the ups.. if the ups doest work that will be the mainboard problem you hav to call for vedor to repair the unit.. yes these fuse for the ups but it unlikely to be blown so should worry of the fuse it self.. change of battery come with different spefc for the ups.. eg su3000rmi3u, sua3000rmi3u, su3000rmxl3u --- battery replacement is 8 pcs of 12v 7ah. sua3000rmi2u-- 6 pcs of 12v 7ah or 8 pcs 12v 5ah. su3000rminet-- 4 pcs 12v 17ah,

On this unit, the likely culprit is the battery and that it needs to be replaced.
With that, you may want to think about the pros and cons of replacement versus buying an entirely new unit.
This unit is a relatively low end ups and the surge supression uses MOVs that wear out with repeated absorption of energetic spikes. That's why the better (and higher cost) UPSs and surge suppressors don't use them. They're not really that good anyway due to their relatively high transient impedance. The better equipment uses a "transorb" -- basically a back-to-back high voltage zener diode optimized for low breakover impedance and high instantaneous power capability. Unless the transient exceeds the design parameters of the circuit, these do not wear out and do not degrade. That being said, I will assume that you would likely replace this unit with a similar one.
The flashing may not be the battery at all and may be the charging circuitry, thus your new battery may not live very long (half the life that you would expect.
Many batteries out there are refurbs and have issues as all used parts do.
If you contact APC, they will likely give you a 35% discount on purchasing a new product.
The difference in price in the battery replacement vs. ups replacement at this level may only be a few dollars more.
I promise that I am not a UPS salesman, I just deal with many on a daily basis; therefore I am giving my two cents to try to thelp you avoid problems a year from now.

Testimonial: "Outstanding answer with right amount of detail. I swapped battery with identical APC UPS that I have and vfd that battery was cause of warning tone."

Yes this UPS will protect the TV and the DVR.
The TV is pretty energy efficient, and uses just under 100watts powered on. The DVR uses under 30 watts, so under heavy load you won't go over 150 watts if just these two devices are plugged into the battery backup side of the UPS. I'm not sure how long this UPS battery last's in a power outage, but since you are not using it to the full 360 watts, you should get double time out of it, though of course, its best to power off your devices as soon as you can.
