SOURCE: Tripp Lite SU2200 UPS has faults
For Tripplite UPS basically if the fault indicator is on you already have to check the power mosfets/IGBT on the circuit board. if you know the basic of UPS you dont need all those schematic diagram to check the thing. by the way, try to check your battery first if its still working. and if the battery is ok, go and check your inverter

Turn UPS on: Press and hold the ON/OFF button for one second.
Run a Self-Test: Press and hold the MUTE/TEST button for two seconds (until alarm beeps several times).
The test will last 10 seconds. All LCD Display icons will be illuminated and the alarm will sound.
If the fault icon remains lit, the battery-supplied outlets are overloaded. Unplug powered devices until you remove the overload.
If the "Replace" icon remains lit and alarm continues to sound, the UPS batteries need to be recharged or replaced. Allow UPS to charge for 24 hours and repeat self-test.

My Tripp LIte Omni 1000 LCD almost caught on fire.
I had been experiencing a spike in my power bill to the tune of 1000 Watts an hour for everything running - 24x7. I started the survey of all my equipment; TV 162 Watts; Fridge 228, etc. but none of these devices are on all day and night. I finally mapped out all the outlets and lights and was about to begin the survey. Other than the flickering lights, one big clue was that my TL's lcd was displaying a spike in voltage DOWN to 95 or so, the relay would click, etc.
I decided to begin my survey and use my second TL to help me see which circuit was faulty. When I looked at the LCD, it was blank. I pushed the ON button and all the devices plugged in went OFF and then I saw smoke coming out of the back. I quickly unplugged everything and then watched my meter. When this UPS was plugged in, there was about 1000W used per hour; I monitored it for 10 hours; 400W were used (total).
So... not only was it a fire hazard, but it sucked up 900W or so an hour.

The UPS needs to have a good DC Buss for it to work. Before you buy the new battery disconnect the battery & unplug it from the wall. Push the on button to reset the logic. You may see the display flash breifly. Install the new battery. Then plug in the UPS and turn it on and enjoy
