Member: 81153 Status: Offline Thanks Meter: 0 | Repair flowchart! Hello friends! This is a VERY good and informative topic if carried forward... Lets add info to this thread! My contribution, Check for 2.8 volts on r224. When u press power switch, it should go to 3.2 volts. If no voltage thenm power ic (ccont) is faulty...now from here onwards, even I am at a loss... Maybe reflow ccont? and check voltage again? also, check continuity between r224 and r 402. Also, it has something to do with v414 and v202 Please keep this thread alive! Reagrds Raja3333 |
