There are manual settings on most projection tv's to adjust the size and to bring the picture down so it is centered on the screen better. Try adjusting the three colors mentioned below first. All projection tv's are pretty similar. If you need to adjust the picture manually, which you should not have to, there are manual knobs behind the front of the tv or at the rear. They should be marked for thier function.

Here is how to adjust the convergence one color at a time.You should be able to get to the convergence screen with your remote. You need to go into the setup screen and read what is on the menu there. It should say how to adjust when you get there.

Convergence- The Auto convergence feature automatically adjusts the TV’s tubes
(this may take several minutes, after which you can make fine adjustments to the
convergence settings); Red convergence displays the Red convergence screen,
allowing you to use the arrow buttons to align the red and green images; Blue
convergence displays the Blue convergence screen, allowing you to use the arrow
buttons to align the blue and green images.

Also this is in the manual for a generic projection tv.

Call 1-877-RCA-HDTV and have your unit’s date of purchase and model/serial number ready.
• A representative will troubleshoot your problem over the phone.
• If the representative determines that you should receive service, they will provide you with the name(s) of the
Authorized Service Center in your area.
• Contact the Service Center and arrange for home or pick up, repair, and return service, provided that your unit is
located within the geographic territory covered by an Authorized Service Center. If not, you must take your unit to the
Service Center location at your own expense, or pay for the cost the Service Center may charge to transport your unit to
and from your home.
• Proof of purchase in the form of a bill of sale or receipted invoice which is evidence that the product is within the
warranty period must be presented to obtain warranty service. For rental fi rms, proof of fi rst rental is also required

Here is a link to rca tv manuals if you don't have one.
You can download them in pdf.

If this is not a help, please give the specific model number.

Convergence on a r56wh78 rca projection tv


I located the problem with this set and wanted to pass it on to help anyone with this problem. the chassis # is ITC222A and the problem turned out to be a fuse on the High voltage board. There are 3 fuses that sit next to the flyback transformer and the middle fuse (400 ma 125v) was blown.

RCA 46" Rear Projection TV - Picture is Blurry and RED


That sounds like the screen and focus controls you are adjusting. It sounds like you have a bad HV Splitter inside the TV. #205064 or #204809 Depending on your model number. http://www.matelectronics.com/acatalog/Mat_Electronics_Replacement_Parts___TV_134.html sells them for about 20 bucks.
