The screen is always blue, and gives no image.

Resolder the convergence IC pins chances are the solder is causing the issue since it seems to correct itself.

Best way is to download the pictures to a computer through a card reader (optional). The blue blank screen could be deleted images using the garbage can icon. Retrieving those images can be done but it cost to have a recovery program used and there is no grantee that the images can be extracted because the card my have been written over or formatted. Once you have your images saved to a computer the memory card should be loaded bak into the camera and the memory card formatted to give a clean working surface for the camera to write new files to.

Have you changed the settings for the mode that its plugged into? The problem is either the mode is out of sync or the video card is faulty

Your tv is an LCD projection one - in which the image is generated by 3 small LCD screens. The blue dots are pixels from the blue LCD that are dead - always fully open.The only fix is to replace the LCD panel and that is going to cost you around $300.

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.

Go to menu ,now go to setup see if convergence is on menu if not then fuse FL231 is opened 0.6 amps it is located on right side of flyback transfomer the fuse in the middle they look like small square capacitors brown there is 3 in a roll.

The convergence integrated circuits have failed and most likely the 2 5A fuses have opened as well. I would find a local Mitsubishi service shop.

Convergence ICs are bad and posibably th eresistors that power them. Its an easy fix if you can solder

2 months old? I'd call the dealer..it's under warentee. You have a problem that will not get better.

You will need to repair the convergence circuit to fix the double image. The second issue of the "perfect focus" stopping at 37% will be fixed at the same time. It is halting because the sensors detect no movement of the blue image. here is a link to the part number and how to purchase the board. http://www.partstore.com/Part/Samsung/Samsung/BP9500142E/New.aspx
