Ok maybe this will help :  when "DPMF Low" is low, V1 equals to 15V and V2 nearly 0V, which is normal. But when DPMF is 5V, V1=11,2V and V2=11V. Output current on transistor collector is 0.33A , but even if i cut all after transistor output, and i place a 100Ohm resistor for example (0.15A), V1 fall down to 11,8V ??? D924 and C925 have been changed without success ................. Thanks for your help |

| Hi, I've got a problem on a LG 775N monitor. When I power-on the monitor, the power led goes on. A relay is clicking, I hear some noise as if the high-voltage is generated and then it stops. The relay is clicking and the power-cycle starts over again. I check secondary voltages on SMPS, there is 4 lines : 75V, 160V, 6.3V and 15V. Everything seems to be ok except for 15V line which is only 11V , i thought one component were dead on the 15V line but couldn't find one ?? also on THT no -30V, -120V, -40V etc. also B+ transistor driver (IRF9530) is very hot after 30 seconds ...... |
