Just acquired a Pentax 645N. On the first roll, I see 6 shots with a light leak (out of 15).
There might be several reasons but what makes me annoyed is the difficulty to find out in my area a tech that could fix the problem.

Qualified technicians are getting rare everywhere. I wish some would embrace the craft; there is a market niche.
It's tough to sell service where the object is decreasing in $$$ and labor cost is only increasing.
Make sure you have continuous light seals on the back/door. My Mamiya 645 had a light leak when I got it, It was caused by the shiny metal latch for the door not having foam behind it, the light would reflect off the shiny metal and into the camera.
It's easy to check where it is on most cameras with a flashlight, dark room, lens off, leaving the shutter open in bulb mode.
I was intimidated at replacing foam myself at first but it really is something that anybody can do.
same patterns on all 6 shots although. the "intensity" isn't quite the same.
sorry there might have been a blank shot on this first roll...
thx for so many replies
to reddesert: the line goes all across the frame: i could not download the whole shot coz there was a pixel limit

Without knowing how the shutter travels on that one, my bet is on the shutter being the problem. Normally a light leak (from seals or otherwise) will have a somewhat random shape, irregular density (within the leak area) and just generally a crazy looking pattern.
Your’s is very straight, across the whole frame (as others have commented, it would help to see the edge
of the film outside the live area) and within that lighter area, although I see some variation, it is hard to tell how much of that was actually the subject lighting.
Have you tried removing the film insert and dry firing so you can observe what the shutter is doing? That doesn’t always reveal anything, but it is easy enough to do just in case.
At minimum I would inquire about returning it for a refund. There are plenty of these for sale and instead of going the repair route with an unknown repair person, maybe just side step the whole thing?
