Another newbie here. The power supply for my tv went out, so I thought I would use a pc power supply I have. It's a Dell HP-U280EF3, 280W power supply. The tv power supply has a 4 pin cable with 2 24V 6A pins and 1 gnd and 1 12V 3A pin. I planned to use the -12V and +12V from the pc power supply for the +24V and another +12V feed for the +12V. The Dell power supply outputs +5V/20A and +12V/18A and -12V/0.3A.
I have it all wired and it works with no load, but as soon as I connect the TV, the power supply shuts off. I assume this power supply has some logic that checks for overvoltage and shuts off.
Can someone tell me what to look for (relay or transistor that can be bypassed to "trick" it into running)? Not sure where I could find schematics for this.
Thanks,
wayne
