The convergence is controlled by a separate power supply board and that board needed to be replaced.
take a look at the following web site information. Unfortunately, some
RCA sets have manual convergence boards - which means you can do
nothing but replace it and adjust the manual controls on the board
But some of the newer ones (Maybe yours) can be accessed through the
service mode. So, give it a try. I have also copied the part of the
web site that gives the entry code to get into the service mode:
5.4 GE / RCA / PROSCAN
Read the _ SERVICE MODE WARNING _ before proceeding.
To enter service mode, push and hold the [Menu] button on the set.
While holding, push and release the [Power] button, then the [Vol +]
You will now have some information on the screen: "P0 V0"
To actually be able to change these values, you must push [Vol +] on
the remote so the information reads V76. Then pushing on the Channel
+/- will change the "P" value.
P1 - 3 are error codes. If there is a problem with the set that can be
self-diagnosed, the "V" will report the code. These codes are available
in the RCA repair manual.
P4 - 7 control the horizontal size, shift, vertical size and shift.
You may also find a summary leaflet for the service tech clipped
somewhere inside the chassis. The procedures for getting into the
service mode, as well as the service items of interest will be there.
If you're attempting to adjust color or geometry errors, you'll need
the Video Essentials DVD, Laser Disc or some other source of test
With luck, you MIGHT be able to adjust it back into better alignments.
If you end up needing service, the price of the convergence board - if
you can get it from RCA Parts - should not be over $100, but I have not
actually checked it lately - and it depends on the model.
The installation is quite time consuming, so it may take a couple of hours for a tech to install and align it.
In my opinion the $400 plus charge is way high. I encourage you to look
elsewhere. Also, the RCA web site has a link to authorized service
centers; you might try that, also.
Wishing you the best,
