2 - 48" fluorescent bulbs in the kitchen were replaced w/ 2 LED bulbs ...ballast was by-passed there is a 1-2 second delay for the same bulb, each time the light is turned on ...is this common? O K ? thanx

We have track lights that came with the house when it was built in the year 2000. There are 2 tracks in the bonus room, each on its own wall switch (not a dimmer). Track A has always worked fine, but Track B (on the other side of the room) would occasionally power on but never reliably stay on. Both bulbs on Track B always turn on and off at the same time. We ended up never using Track B for the past 10 years. This month I decided to finally fix Track B. It's a monorail-type track made by a company called Prima. I got on a ladder and tightened the allen key set screws around the mounts and generally fiddled a bit with the track. I was able to get the track to work for the past month reliably. Then one day I switched on the wall switch, heard a 5 second buzz coming from above the ceiling, then the track went dead. This time for good. No fiddling would bring it back. Tracing back the power lines into the ceiling I found that each track has its own transformer up in the attic. Each transformer is labeled Tech Lighting AT300T Input 120VAC 60Hz, Output 12 VAC, 300w max, 25 amp max. My question for you is how would approach troubleshooting next? It seems like replacing the transformer has a high chance of success, but I'd like a second opinion before spending the $200-250 for a new one. Thank you in advance!!
