The machine for the 17-inch flat-screen sc-reens, power is the core component thick film ICDP904C, the appended drawings is according to the physical part of power supply circuit pPxservice manual download site

As fuse in good condition, and electric logging C605 on both ends of the voltage of 310 v (I mains in around 240 v) normal, measuring T601 subprime each are no voltage output, obviously fault in power supply section. Measured again IC601 power end voltage of 0 v (abnormal), (3) feet suspected damage of thick film blocks DP904C of power shutdown (3) feet over the ground resistance measurement for 4 Ω, short circuit state, with a hollow needle with electric disconnect DP904C (3) after foot, ZD601 negative still dark short circuit to ground state, failure is nothing to do with IC601. So doubt stabilivolt ZD601 breakdown, or filter capacitor C606, C607 has serious leakage, by observing two capacitance appearance in good condition, considering ZD601 damage probability, remove the ZD601 its positive and negative to just 3.5 Ω resistance value, breakdown, has been completely replace with a 33 v voltage regulator tube, and welded good IC (3) feet. And an electrical commissioning power, troubleshooting. pPxservice manual download site
