Totally dead | It is an 11 thousand btus portable air conditioner that has a recurring defect on the main board | Generally the problem is caused by the ci viper22 (u1) which burns in a short without blowing the fuse, in my case it burned several components on the board: one of the bridge diodes, the optical coupler (opt1), check the tl431 (u6), replace the schottky diode (d5) with another with a higher capacity (take it from an ATX power supply scrap), 47u 50v capacitor (e23) blown, 330u 25v capacitor (c3) bloated, check the 7805 (u7). | 2000 |
