Flyback was the problem. Used a HR6466 for the 200418 (OEM may be NLA). That let it start right up. New fly had about 45 rings compared to the 30 of the old I guess that is enough.

Haven't ordered it cause it's a shop set---might go into my den since it's a very nice upright console 35". i believe the best price I found was ness electronics. The only charge $1.99 shipping for all online orders (I would have to assume that dont mean antennas) TV Doctor Avalon, Wi ----- Original Message ----- From: "Peter oliver" <oliver_peter1@xxxxxxxxxxx> To: <techassist@xxxxxxxxxxxxx> Sent: Friday, May 14, 2004 8:33 PM Subject: [TechAssist] Re: Proscan PS31150 CTC169GL in shutdown/dead > This one would seem to lean that direction, hooked the flyback up to my old > sencore equipment only got 30 to 35 rings out of it, most good flybacks seem > to average around 70 or so the reallt bad ones a few or none at all so ?? > Anyone know the part number doesn't show on tritronics for this model. > > Peter Oliver > Tucson Radio TV > > PS is it just microsoft hotmail or is no one sending or getting email today > haven't seen any mail since this moring. > > > From: "Jeff Farnsworth" <jlfonz@xxxxxxxxx> > Reply-To: techassist@xxxxxxxxxxxxx > To: <techassist@xxxxxxxxxxxxx> > Subject: [TechAssist] Re: Proscan PS31150 CTC169GL in shutdown/dead > Date: Sun, 9 May 2004 01:41:30 -0500 > > Just traced one down to a bad flyback.
