Is there any way to adjust or fine tune convergence on a LCD rear projection TV?
Yes there is. ALL LCD/Plasma televisions have adjustment for convergence, RGB drive, color saturation and a virtual host of other parameters than can be adjusted through the "technician's service menu".
Unfortunately, you are not supplied with the information to access that menu and you're limited to a "user's menu" which allows you to only adjust some of the basics, like volume, tone, color, tint and several more.
Methods of access vary from manufacturer to manufacturer. And the main reason that a consumer isn't given access to these menus is simply because they can totally screw up a set with just the push of a button, requiring hours to correct by a qualified technician.
Of course, most all of them have a factory default to recover most of the settings, but there's still a lot of finite settings that would have to be adjusted to get your TV looking right again.
Depending on the LCD manufacturer, it may be adjustable for your specific set, or you could have a problem with the LCD digital or driver modules. Even the LCD display itself could be failing.
Best bet is to call a QAUALIFIED technician and have it checked out. If you don't have an extended service plan from where you purchased the set, or if it's out of manufacturer's warranty, some of the repairs could be quite expensive. enough so that it may be worth looking into buying a replacement set.
I've been doing LCD/plasma repairs for the last year and a half for a big box retailer, so I think I know what I'm talking about.
Another opinion from a WikiAnswers contributor:
unlike big screens that hav a red green and blue light the lcd only has 1 light so I'm guessing no......best to contact the manufacturer and see what they say to do
Rear-projection technology allows for large displays; rear-projection televisions range from 42" to 80" on the diagonal. Furthermore, rear-projection televisions are comparably less expensive than similarly sized plasma televisions. The rear-projection television is also very simple to set up, as no drywall work is required.
I, like many others who contribute to WikiAnswers, know a great deal about rear projection television and similar commercial display technologies. That's answered the question fully so little more can be said. However, specific questions about rear projection equipment, techniques and possibilities will result in far more specific answers. They will be useful in a way that this answer most certainly isn't. We look forward to seeing some more questions about rear projection.
In a Chevy cavalier a head light can adjust at the top or bottom where does it adjust in a 1989 Chevy cavalier top or bottom?
This Television is a rear projection CRT display. Front projection uses a self contained "Projector" usually hanging from the ceiling and shoots the image onto a fabric screen or wall. The projector in the RCA HD52W59 is actually inside the base of the unit and the projected image is bounced off of a mirror and onto the back of the screen There are many types or Rear Projection displays: CRT, LCD, DLP, LED and Laser.
This will depend on your specific brand and model. Most models will allow you to pull up the convergene menu by using the original remote. Once is displayed on the screen you can try to fix it. Note: I you are not able to move one or more colors in any direction your convergece chips have failed . If the convergence is slightly off try running the manual convergence instead of using magic foucus. 1)…
