Question about Sony SDM-HS74P/S 17" LCD Monitor
The 1000uf/16vdc caps are for the 5vdc logic, there should be at least tow caps rated at 25vdc for the 15vdc inverter circuits. Try using 1157 12v car lamp attache to the 15vdc, the power switch will have to be off (the 5vdc and 15vdc are always on) so the inverter circuits will not be drawing the current from the 15vdc power supply, the 15vdc should be at 15vdc +/-1~2v with the lamp load. If it is steady, then you still have problem in the inverter circuits which can be the lamp assemblies, inverter transformers, Transistors/IC. I use test lamps set up to narrow down the problem to find out if it ia the lamps or the inverter circuits.
