About a week ago I transplanted my peace Lilly to a larger pot, since then the tips of the leaves are turning brown, please help.
Yellow leaf tips/edges often means a leaf is not getting enough moisture. However, this can be due to under or overwatering. Overwatering causes rot root in peace lilies which means not enough healthy roots are left to nourish the plant. The result is that your plant looks like it needs more water! Perhaps your potting mix is too dense. Try adding additional perlite to your mix to make it drain and dry faster. For now, slide the plant out of its pot. If the soil is wet or roots look soft and rotten, replant it with dry mix and water gently. Make sure the soil is dry one inch down into the soil before watering again. If you re-used potting soil, there is a chance you introduced microbes that are attacking the roots.

These both sound like fungal infections. This will require, mostly, preventative maintenance. Make sure to let the soil dry out down to about 2 inches deep before watering again. Indoor plants need time to dry out between watering. If they do not get a dry period then the result will be a fungal infection.
Treatment will be relatively straightforward. Next time that you water (and you should only need to do this once) just replace 1/4 of that water with peroxide. This will kill off the infection in the soil without harming your plant.
You will still expect to see much more damage before it gets better. It can be quite difficult to get rid of an infection once started, and treatment will do a slight amount of damage too. But there is still a chance to combat this.
This appears to be a soil additive, nothing to be concerned with.
They likely are a slow release fertilizer.

I don't have any additional details. I try to water regularly & keep the lily in a light room but no direct sunlight.
Over or under watering can cause yellowing leaves. Exposure to cold can cause leaves to turn black.
If just the tips of the leaves are turning black it could be from over fertilizing or using water from a soft water system.
Try using distilled water or rain water to water your plant. Peace Lily can be sensitive to the salts.

Has had 2 blooms in 3 1/2 years. Ready to pitch it.
There are several reasons why this could be happening. Fertilization, light requirements, and water requirements will be a good start.

The white part of the peace lily is curling & brown. What have I done, or what do I need to do?
This is natural as the flowers start to drop. If you are starting to see this on the leaves instead, then you can start to worry. There is nothing to be done but to cut the flower start to the base when it is completely dead. Here is an article that will give you more information on the care of the plant: https://www.gardeningknowhow.com/houseplants/peace-lily/peace-lily-plants.htm
I have a large Peace Lily in my office and some of the leaves start tearing or splitting. Also, the edges on some will get brown. I am cutting back on water to see if that helps with the edges. What do I do for the leaves that split? What is causing it? It does get brushed against due to its size as people walk by, and I wondered if that was the problem.
Browning leaves may indicate over-watering, but split leaves could indicate low humidity. Perhaps the plant is not experiencing the ideal environment. Here is an article that may help:
