Dead Sony KV-21FV1U Combi TV
Hi. I'm not sure if this CRT set qualifies as a vintage set or not. Apologies if posting this is not quite kosher. Last used it was working. Gave to a friend who had it stored for years. Now it's completely dead. It's been dropped because top left hand corner shows signs of stress. Remote not working, but I've just bought a working one that I should receive in a few days.
There is a push switch bottom and to the right. It does not lock in. I wonder, does anyone know of this switch is suppossed to lock in? Any known typical faults that occur? Thanks. EDIT: I'm almost cannot be bothered repairing this set. So, I may offer it for sale as non working. Would be a pickup job for a buyer. Last edited by radiozero; 29th May 2019 at 4:57 pm. |

On the earlier sets, it was the master mains switch, so that all power was removed when it was unlocked. |

Re: Dead Sony KV-21FV1U Combi TV
Ok, I got off my butt and took the back cover off. I see that that square button at bottom left is not a mechanical latch type. The actual switch behind the button is a simple (and very small) press switch, like you might find on a remote control. Press it in and contacts will close, until you let go and contacts will open. So, any latching will be of an electronic nature. I am assuming that when that square button is pressed, the TV is supposed to come on, with a picture showing on the screen (or "white noise").

Aah. There is a power switch that latches in on a push and that latch releases when pressed again. That is a push switch has a round knob to it. It's bottom right position. When I press that in, the TV gets power. And I can see that because a little red light comes on near the push switch with a square knob. I think the TV should come on when I push that square knob. But TV is dead.

Re: Dead Sony KV-21FV1U Combi TV
OK I've solved the issues which were. a) I did not realise that turning this TV on was a two part operation, turn on mains master switch (bottom left), then press on/off switch (bottom right). b) when you slacken those screws holding in the circuit board assmbly, when finished messing, make sure that the assembly is "home", otherwise pressing the on/off switch won't actually do anything because the switch fails to get pushed in.
So, I have a working KV-21FV1U, tape section works as well. I may offer it for sale. Probably will. Rich Last edited by radiozero; 29th May 2019 at 5:54 pm. |
