Sony T.V.

[Vince and Marge]

Hi!
I have a Sony Color T.V. that I need some help with. The thing will run
good for about a week and then it acts up, I can run the chanel numbers and
all I get is hash in the background, like its trying to come in.I replaced
both of the tunners and it still does the sames thing, after turning it off
and on sometimes it will work again and then sometimes I have to wait until
the next morning, I have resoldered about all the connections on the main
chassis and no luck.
Would appriciate any help I can get. O! the set is Mdl K. V. 3568
Chassis AA 2D98.
Thanks
Vince.

Vince:
Did you replace the SIF/VIF block ?

I've had pretty good results resoldering these older IF blocks, although you'll
need a pencil iron with a fine needle tip to avoid soldering everything
together.
