I had a similar fault some time ago on a
Seleco model and this was due a dedicated IC. IT was the TDA 4502 (28pin) but
by mistake I bought the TDA3301b. Fortunately the shop owner took it back and
gave me the money. He did not had a new TDA4502 because they are absolete,
but I obtained one from a scrapped Seleco chassis I had in garage. |

I changed the TDA4502 and the TV came
working well. |

It is a brilliant idea
to make a new base when changing large Ics. |
