philips 60pp9202/17F Screen driver adjustments	Can't Post

I had a convergence problem that got corrected after replacing the STK's and a couple of resistors.
Because of a very stupid mistake I had made, I had poor color quality and tried adjusting it by moving the "screen" control knobs that drive the colors.
Although after correcting my stupid mistake, I was able to readjust the "screen controls" and have a good picture, I know thee is a proper procedure for adjusting the screen drivers for proper color quality. I would appreciate If someone could provide it.
Thanks!,
Emilio

JTS- I had an older RPT that had a switch in the back to put it in service mode which generated a single line across the screen. You covered two of the CRT's and adjusted the color of the non covered crt so that the line was was just visible .... .
This set (Philips 60920217F) does not have a service switch in the back-there may be one on a board?
It is the specific procedure I am in need off.

Edit: Newer sets are "all about the numbers." Very few, if any, rotary adjustments or slide-type switches. If you can not comprehend the manual, I'd suggest letting a professional do it.

Have fun - but be careful - can easily f#*k it up. Read 1st - jot down original.

JTS... Thank you very much for the link. I had been under the impression that the service manuals were only available to authorized service technicians from Philips.
Once again, THANKS!

vansci123- I also have an older RPT that has the service switch in the back. This one does not.
I was able to reset the controls to the original positions by zooming on a picture I had taken which showed these controls! Once I was able to reset them, I only needed small teaks to optimize. Lesson learned = always take pictures.
