Question about Sharp 25VT-J100 TV
You dont have enough vertical sweep!! Best thing to check is the vert output device and I think its an IC . BUT before that check the b+ going to that device and see if its low. I will run through a silicon diode right next to the ic. Measure both sides of the diode and if theres a big voltage drop then the diodes bad. Now also these sets are common for the b+ filter cap off thge flyback transformer. Its the voltage line that feeds that diode and the vert output section. Now measure all caps out of cucuit as most will measure good if you dont. Also just for giggles right nrxt to the big IC that has the vert ,horizontal video and sound drive there is if im not mistaking the vert parts start with c4-- or the ic will be ic4-- Its a small cap that will sayc4-- attached to nothing but the ground and one pin of the ic. I've seen this cap cause all sorts of vert problems in the past as its the vert waveshaper capacitor for the vert osc/drive. Good Luck
