If you changed only the bulging capacitors, Try changing some more around those. They might be partially damaged already with out external signs. I replace all the PSU capacitors to solve this problem.

Everytime we turn on our tv, all we hear is a click sound and all you see is a black screen. it wont turn on for 20 minutes and its been getting worse


Something is failing, albeit slowly. By hearing only a click does that mean the sound is dead too? Regardless, you most definitely have a hardware issue.

Get it repaired sooner than later. I am happy to assist you further if you are doing this yourself. I don't recommend it if you are inexperienced with electronics and high voltages.

When I turn the TV on it clicks 10-12 times and finally turns on.

Sounds like you have bad capacitors in the power supply. If you look they will have a bulg on the top, replace them and you should be ok.

The tv will not turn on

Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
