I have a mod that corrects the streaking in the 808 if its the leaking cap issue.
Some of the most common problems come from the VPH06 chip.
They can fail 1/2 way causing focus issues and also streaking.
IT depends on the build number. Some of the early ones had much more problems. There is a small number at the bottom to tell you the production number that is when it was produced at the factory. This does not always line up to the year of the unit because sometimes they were shipped or stored at different years.
