Posts: 336 Gender:	The 3M25 Makvision series seems to have had a bad run of vertical IC's. Flatline with no vertical deflection. It wasn't worth having to send the entire unit back for warranty as shipping far exceeded the cost of a NTE 1869 vertical ic whick out of the last 10 of these 6 were defective and the vert ic fixed all 6.

Posts: 37 Gender:	Makvision 3M25 repair... clicking power supply... tested all components you'd think were candidates... turned out to be a bad 47@25 cap behind a skinny heat sink in the power supply section.. bulging top. BE sure you note the shaded dark area under the cap is + unlike other boards or you'll be replacing the cap twice, once after it explodes! This cap is just to the left of the 2 pin mini plug for the pic tube 2nd deguassing type coil. Don't bother happ techs with this... "oh- that could be anything" response. Do note that Happ has all schematics on their website under the product number in PDF.
