Surface 4 Pro screen bulging at lower left edge and separated from the frame

I have a Surface 4 Pro that I purchased in March 2016. Over the last few days, I was seeing a considerable color bleed on lower left edge of the screen. Then I stared noticing that that type cover does not seem to close flat against the screen. On closer inspection, I found that the screen is bulging (curving out) on the lower left side and the screen edge has separated from the frame, exposing a gap, Some of the circuitry inside seems to be pushing out as well from what I can see through the gap, indicating something inside is exerting an outward pressure. I pushed the screen back in and with a little pressure it got flattened. However, after a few minutes use, the screen bulged out again. There is no physical damage to the screen, the bezel or the device in general, no cracks or scratches.

What is causing this and what is a possible solution?

Thanks,
