My tv the letters are blurred like theres 2 letters

Is it like a haze? The convergence can be the issue too... Before you call in a tech, try to go into the menu and reset everything to default. Next, clean the filter and then if you are willing, take the cover off just below the on set menu buttons. the panel pops off... behind that on the left side is the lamp box, you can check to see if there is a lot of dust, if the set has been off a while, even unscrew the screws and pull the DLP bulb out carefully and inspect it. The only thing you are looking for is burn areas in the lamp. It would be on the top of the bulb and is caused from excessive heat.

My official guess is probably to say the set needs serviced by way of a proper cleaning, and convergence adjustment.

You need to do a convergence reset
