| thanks for your input. After DLing the service manual it appears my set does not have the C707 or E994. All fuses seem to be good so at this point I think I'm in over my head. Thanks again. |

| if this set has them you wil find c707 just in front of flyback,under glue and between 3 large capacitors.and e994,2a fuse on secondary of power supply.if fuse is open i believe the one led will not light.also check for burnt resistors next to convergence ics.if so replace open resistors and ics. |

All 6 LED's light up when I hit the power button then all but one turn off after a sec. The one labeled D903 or D975(can't tell which number corresponds w/ it but it's also labeled "protection" w/ an arow pointing to it) remains on. Any suggestions as what to check for? thanks in advance.
btw: While researching I saw that similiar models with a similiar problem were fixed by replacing C707 and E994 but I don't see those on mine at least not in the same spot. |
