Most probably the laser getting tired, the VK-D5se uses a Phillips Vam12 laser, find out on google if it’s interchangable with any of the other Vam ones, as they are all very cheap to pickup on ebay, even the whole mechanisim with laser, just a plug and 4 bolts and your done.

And looking at the inside if your handy, it’s not very hard to do yourself, look at some youtube vids how to change Philips vam12.
