C2046 47uf @50 V and C2A04 10uf @50v. This should stop your rolling. Let me know. |

Minnie,
Any chance you know the approximate locations?
I can't find C2046 or C2A04 on the Signal Board... |

C2046 is near a bank of silver colored inductors and C2A04 is near the center of the signal board by a 2-pin connector AY. |

Same model Tv VS-5007R is doing the same problem as above, the C2A04 resistor has been changed and the C2046 will be changed tommorow when radio shack opens, the question is:
these resistors dont look inflated or damaged in any way, does that mean they are dead or broken? Also C2A04 was changed and the TV turned on as a test and the V-Hold is still not locked down. |
