Dear guys, I have a question. Please help me out as this has been giving me aggressive OCD in the past few days. I am not very tech savvy so don't mind if i sound stupid.

I have a cable internet + TV service from my cable provider. They use Docsis 2.0 system and provide a coax cable to the home. The coax cable goes into a 1 to 2 splitter (it says -3.5db at both the outputs of the splitter). One output goes into the cable modem (via another coax cable) and the other output goes into an LED TV’s analogue input (via another coax cable). A couple of days ago I had an issue with my service so decided to troubleshoot myself. To test the signals, I plugged in the cable (from the cable provider) directly to my LED TV’s analogue input (without the splitter). Now I am worried that plugging the cable directly to the LED TV (bypassing the splitter) may have damaged the LED TV in some way etc. Please help me out!

Stop worrying, it didn't damage anything. Plugging in the cable directly to either the modem or the TV is perfectly acceptable. The -3.5db marked is the expected signal loss due to the cable splitter.

You are fine.
