3d Projection

How much does it cost to fix a Samsung rear projection TV when the picture looks like everything is in 3D?
If you are talking about a CRT rear projection you may be able to fix it yourself. It sounds like the TVs guns need to be converged( the red, blue and green CRTs have drifted and don't point to the same place). To converge the CRTs go into the menu and look for a convergence function. Once there you will be able to align red with the center and the blue with the center. You may be able do a more complete convergence if the TV has a multi-point convergence. Check your manual for convergence. List the model number of the TV for more accurate info.

My Hitachi 55 inch rear projection TV?
My Hitachi 55 inch rear projection TV all of a sudden starting on the left side of the TV going about 3/4 of the way to the right looking like a 3D movie. The green and an almost purple like color are looking overlapping/double (think of the olympics symbol with the interlocked circles) along with the picture being very fuzzy! Have tried the magic focus twice and unplugging the TV for at least 15 minutes. Still no resolution. Please help.
You need your convergence amplifiers replaced along with a set of resistors...they come in a KIT to upgrade the circuit.
Cost to repair is about $350 to $400.

idk but the movie was phenominal. =]
The pace of technology advancements seems to come at the public at an ever accelerating pace. We see Interactive involvement with gaming. new laser driven television, digital 3D projection systems, convergence of technologies in personal communication devices as well as expanded Web 2.0 resources including bandwidth. The list goes on and on.
All of these new technologies also carry a note of obsolescence along with the price tag. The electronics industry has always aimed at this marketing philosophy. Not to do so would put them out of business in short order.
Educational institutions, as a whole, are not among the first adopters of new technologies as they were with the first personal computers. The rise of directors of educational technology within school districts took a more profound look at technology before making hard dollar decisions that were, before their arrival on the scene, made mostly by administrators who had little in the way of standards to follow and were more inclined to compare their technology programs with that of their neighboring districts or bell weather districts that invested heavily in newer innovations. Call it “Superintendent Envy”. There were also many choices driven by shear love of all that sparkles.
The question as to where will educational technology end up in ten years is rather a tempting one depending on one’s leanings; fiscal conservative, research driven pragmatist, or bedazzled technology activist. I place myself in a position somewhere in the middle.
For the most part, ten year hence will see mostly upgrades and replacements for the existing technologies. Upgrades will bring software enhancements and add-ons. What I is see as most important part of the equation is the pragmatic development of consequential instructional resource that will fit into existing and upgraded or replaced technologies. After all, a computer or smart technologies are no better that the programs that drive them. While teachers are quite adept at developing some resources, they cannot be expected to produce the massive outpouring of the educational media publishing industry.
Those parts of the media production industry are the ones who must consistently bring to the marketplace the products necessary to drive the technologies incorporated into the educational setting. The big question will be placed on how universal the resources will be in a global marketplace and how well they fit the curriculum and technologies that will be in place or adopted by school districts.
In the short term I believe that the ratios of computers and smart devices to student personal use will increase. Many school districts and institutions of higher education are now either loaning or requiring students to have portable computers capable of a whole new array of applications. This will become a significant shift from teacher led instruction to more guided individualized instruction.
Lastly, I also see a shift to more on-line and off-site instruction away from the brick and mortar institutions. This will be a slower growth until perceptions, quality and delivery are improved.
