My dsi touchscreen works weird.

before start im not good at english writing. So maybe it’s hard to understand my sentence…. im sorry…

i changed touchscreen few minuets ago.

becasue touch was not exact at center.

and after changed touchscreen, center is well touched.

but left down corner doesn’t work now…

when i touch corner hard, it seems like center is being pushed (looks like when we push hard any lcd it’s color turn s strange for a moment)

is it touchscreen’s own problem or something(ex lower case) is pushing the screen?

thanks for reading.
