On my TV I cleaned the mirror (micro fiber cloth) behind the screen and the lens in front of the bulb (use cotton gloves) and it took off the dark spot

Seems to be magnetic damage. 
Some fix using this method:

Perhaps the manufacturer has a better solution. Good luck.

There is a curveture in the screen in the upper left hand corner. The screen is shadowy with a lot of red bleeding through.

Most likely the Convergence IC's along with bias resistors have gone bad. It's not an expensive repair but I would take care of it as soon as possible. Usually in the area of $250.00 will take care of it.

Have black dust looking spots on my screen.

Yes there is a way. The easiest for you would be to remove the back top of the TV. That will give acess to opt lense and mirror. But first check the Lamp and inspect the lense that the Lamp into. It does not take a lot to cause your concern. Use super soft cloth and wipe surfaces.

Good Luck,Big Irish.

JVC HD56G887 went out, no sound or picture. Both LED and power lights are blinking

You need to replace the power supply board. The new ones have a bigger heat sink - obviously JVC knows about the problem because they made the new ones bigger. It cost $250 from JVC and I installed it myself - took about 3 hours to do. If you are not tech savvy call a repairman. Hope this helps.

I fixed it!!!! If you can open one of the sides (on the JVC there is a little door with a screw), then you can clean the projector lense in the middle on the bottom. It kind of looks like a big light bulb. It seems there is just dust on the glass that is projected onto the screen. We had a big gray spot and cleaned it with a damp glass cloth and Ouila! It disappeared. I scored MAJOR brownie points with my husband for this one! He wanted to replace the TV!
