Hi,
you should change the option numbers on the new board,as written on the tv label:you should also change the display option code accordingly the small label on the low side corner of the tv.first of all put the tv in service mode then go to 'option numbers' line,and so on.

Thanks for reply.
I was able to change the service numbers. GOOG 
After that I was looking for display option code but I didnt found it. Is it in service menu?

hi,the display option code is a three digit number written on the sticker placed on the lower end of tv's frame,externally;with the tv on you should digit on the remote,'062598MENUxxx'where 'xxx' is the display option code.

Hello,
I've changed Y, Z anc control board on Philips 42PF5320/10.

Screen is now ok but I see a black horizontal line at the center of the screen.

Another problem is: between dark and bright areas of the image I see white flashing dots (noise).
This problem disappear if I switch source (tv decoder) between PAL and NTSC mode (the TV resets the screen mode and image becomes regular, without noises.

If I use DVI input, the image is perfect.

Could you please help me?
