Hi everyone,
Can anyone tell me how to do the adjustments needed after replacing the sub board in a PCN5425R? I have the service manual, but it doesn't seem very helpful. There are a number of basic adjustments shown in the service manual with the corresponding screen changes (on page 4-11), such as H size, pin phase and pin amp, that are nowhere to be found in the service mode menus. Are the ones not listed in the menus on VRs somewhere internally? If so how do I find them?
Also, why can't I adjust any of the settings in the 480p or 1080i offset menus? Are these values added to the corresponding settings from the deflection menu or do they override? There is an awful lot the service manual doesn't explain.
I'd also like to do the "screen adjustment" on page 4-12, but I can't locate test points RK, GK, BK or potentiometers VR501, VR531, VR561. The manual has no board layouts!!
One more thing: am I going to need to do the beam alignment adjustment after replacing a sub board? I know already that I'll need to do a lot of work on the convergence adjustments (it's just that first I have to figure out how to do the H size and pin amp). Any others I'll need to go through?
Sorry for so many questions!
Thanks,
Kyle
