Pincushion Problem In CRT TV
I have a problem with the above TV it is a Pincushion Problem Everything in the Tv works fine except that it has a pincushion problem on the two sides of the screen, I check the modulation..not shorted and I changed the Pincushion Transistor on the Heatsink and still no change, I am getting 40vdc on the collector pin of the transistor and negligible or non on the other two, can you advised.
Try adjust the horizontal size/pincushion setting if have and at the same time see if the base signal of the pincushion transistor change or not. If not changing then probably either there are components already bad or the EEprom ic data have corrupted. Sometimes it can be caused by a defective E/W correction IC.
