Well replace the other filters in the vertical section the ones you missed.
Make sure you replace with the same values. kip "vegcrable" wrote in message ... Hi!

How about basic troubleshooting? Do you have supply voltage to the chip?
Do you have vertical signal from the video processor to the chip? What does "all" mean? How do you determine that you changed them all? Do you include the cap on the supply to the chip? Are there any fuses or open resistors in the supply? Leonard "vegcrable" wrote in message ... kip Wrote: Yes but did you put the correct value ones back in.
