Or something on output pin is pulling it down. Does IC932 get excessively hot? What happens if you sub your power supply for 5 volts. Bear in mind that there are quite a few 3-legged regulators in this set. Check input and output voltages on them. Any that prove bad, you may want to change input & output filter capacitors. Edit: That 5 volts goes to many places including video, PIP, even back to FS board. So there's a pretty good chance that's it. If your power supply voltage is also pulled down, measure resistance to ground, if less than few hundred ohms - "follow the short." ------------------------- Location: Far, Far Away
