My screen is blured (focus problems)

My tv was working good this morning and when i got home i turned it on and it was blury. i tried the flash focus and it did not help. i also tried the adjusting the convergence manually option but the color red crosses were ok in the center but the outside crosses (red only) were to the right of the white crosses..it would let me go up or down but not left or right to match them back up... so that is my problem if anyone could help me that would be great thanks for your time...

This sounds like one of your convergence IC's has burned out. There are 2 IC's in the set and the one that handles RH (Red Horizontal) has stopped working. The IC should be replaced and the set realigned by someone with experience.

Picture is bluring...especially the writing..
If you are comfortable working inside the set, locate the flyback transformer (part with large red wire coming out the top.) This part should have 2 controls on it. One should be labeled screen and the other focus. Try adjusting the focus control a bit. If that fails to resolve the focus, please update this with the make and model and additional details will be supplied.

Thanks,
Dan

Cannot get the set to focus. Colors are blured
Sounds like a convergence misalignment, go into the tv menu and look for other adjustments sub menu and follow the on screen directions,this is a simple procedure but will take a little time to get it adjusted just right. Directions are also on pages 20 and 21 in your owners manual. Good luck!

Left side and right side are blury.
With projection sets, there is typically several settings for which you can display an output. You probably have a "wide" or "stretch" as a setting for the tv. What you want is normal, or some setting which doesn't result in a stretch. Widescreen projection tv's try to stretch 4:3 output into the widescreen setting, but usually this just results in the middle being in focus, and the outer 20% to be stretched on each side, bluring the edges.

Try to manipulate as many "tv settings" as possible. For most sets this is only available with the original remote. If you don't have the original remote, changing these settings could prove difficult.

Camara not focusing/ zoom not working
Its an error code and shows problem of Lens mechanism.
Lens focus / zoom motor is stuck that's why camera gives out of focus image.
You need to replace Lens Assembly and it would cost you more then camera worth.

My projection tv sony 51 inch red out of focus
Your convergence output IC's have either shorted out or opened up, either way they will have to be replaced and possibly a resistor or two. One distant possiblity is the DCU or the Convergence Yoke, but most likely the IC's. You will probably want a tv repairman to do the repair as there is some soldering to do and some paste/ IC's to install/ calibrate. A repair like this could run from $300 - $500 for IC's depending on who does the repair, The Yoke or DCU would cost a couple hundred more.
