if LVPS is bad, is it possible to replace it?
really appreciated your help, I am not ready to part from my loved CRT and convert to the digital, me and my wife love watching movies on that machine!
So you have 2 red lights on?
Red light on back of machine labeled LVPS
Red light in front of machine ,on the LVPS itself, second from left
the 2nd from left light indicates a problem on the -85Volt rail. the only thing on that rail is the video neck-boards which slide onto the back of the tubes. These could have gotten knocked loose
I would start by pulling re-installing the LVPS, then check the Video neck boards (VNB's) . 3 of them under the gold covers, I would just push on them, evenly, and see if they go in further.
Or, slide them back, clean pins with alcohol, re-install. Risky though , you have to be very careful, do not force, if you bend the pins tube is ruined.
I've attached a document talking about LVPS
