Tab 3 P5210 Won't Power Up

[KMC]

Hi
My Tab 3 was dead and wouldn't charge. I replaced the USB charging port. The tablet then charged fully. I turned it on and downloaded 4 movies. It was only turned on for about 30 minutes. After the movies downloaded, I turned the power off, now it won't come back on again. I have put it back on charge, there is no sign of anything happening.
I have tried the holding power button and volume up and down ect...and nothing.
Any ideas. ????

I have to mention, I ordered a new battery that arrived in a jiffy bag ! I did put the battery in but nothing happened , I thought the battery may have been damaged in transit due to the poor packaging, so I put the old battery back in. The old battery was in when it charged to 100%

Thanks

Sounds as if it may not be the battery that's the problem, perhaps a loose connection?
