Your YSUS is overloading, If you take the back of the TV off, its the larger board on the left, it is connected by orange ribbons to two vertical spanning boards that are thin and long, those are the buffers. Looking at your Y main, you'll see four small philips screwdriver adjustment recievers, they are about 1/4 of an inch square, these control the different voltages used by your board. They are tricky to align just right, BE CAREFULL and adjust these slowly with the power to the TV on and see if you can clear up the snow. PLEASE take it easy and watch what you're doing, these boards are running super high volatges and can put you in the hospital or worse. If you don't want to deal with it adjusting it, start by replacing that YSUS board. Usually when either the buffers or the YSUS is bad, it takes the others out with it. If the snow doesn't clear up, replace the buffers. If this still doesn't fix it, you can try replacing the XSUS.

Red and green snow near the sides of the screen


As in there's blotches of red and green at the edges, but the image is still there?
If so, then your screen may have come into contact with magnets, or maybe the alignments are off (TVs align overlapping images in red, green, and blue).
As always, check with the manufacturer support lines, as they would have specific information for these kinds of scenarios.

Red lines on Sony KP51HW40 Rear projection TV


Yeah, seen that more times than I shoulda in the last 4 years. The red picture tube has a cathode to heater short. That means it's no good. That red picture tube is no longer availible. But all is not lost. There is a company that rebuilds those tubes reasonably. Most reputable tv shops will know this. The ones I've done cost around $450 out the door. One minor hitch is that with all the shipping involved the job usually takes about three weeks. That can be expidited but then the price goes up.

Green line down left side and geen snow


Horizontal or vertical bars on the screen could be from an ac line interference, adjacent magnetic field, bad input wire connections.....especially HDMI connector cables. A bad HDMI cable causes all kinds of unwanted picture interference. Check the conditon of all connection wires for proper fit and function. Keep in mind the method in which you connect your tv will result how the tv performs. As well this line problem could be a circuit issue too, requiring a technician to look at it.
