My ps3 is not playing any original dvds code 3 and code 2 what should i do?

PS3's are dvd region specific meaning that if it was made in north america it will only play dvd's in region one. The dvds in these region codes are not compatible with a region 1 device which your ps3 is. 2 Europe (except Russia, Ukraine, and Belarus), Middle East, Egypt, Japan, South Africa, Swaziland, Lesotho, French overseas territories, Greenland 3 Southeast Asia, South Korea, Republic of China (Taiwan), Hong Kong, MacauAlso the reason they have these codes is so that they can limit what goes out to each region, so certain content can be viewable in what is legal in that region. My recommendation is to sadly, repurchase the dvds anywhere in North America and they'll compatible.

However, you can use a program called Leawo Blu-ray Copy to make a lossless copy of your Blu-ray disc and remove the Blu-ray region code on it while doing so. You can check on this:
