Question Update Philips 51PP9200D37 Problem

Ok i pulled the board out. I checked all the resistors with my ohm meter all seemed to checked out fine. I then proceeded to check the convergence chips with the meter, there is a difference between the two. Not sure what they should read on the ohm meter but checking the pins on one the meter went up and stayed checking the second. In the same manner as the first the meter went up then faded away. Now correct me if i am wrong but thaat shouldnt be. That would mean that that chip is bad wouldnt it?

Maybe, but it is very hard to check for anything other than a short without the set running. If you have power to the ICs on both + and - supplies, and you cannot adjust one or more colors, you likely have a bad chip or something open.




Looking for me, just google my username. I have used the same one for most sites for many years.
