Question about Sony FD Trinitron WEGA KV-32FS100 32" TV

1 Answer

TV goes black at bottom and has horizonal lines in middle?

I have a Sony Trinitron several years old. Turned it on and the screen went black at bottom and had lines in the middle of screen. then it would go completly black and I can turn it off and the picture will come back on. When it does this again I can tap the side of it and the picture will be normal. I have to do this several times and so far as long if I don't turn it off it works finefor the day. I took the back off and I noticed when I barely touched the wire going to the flyback it would work normal. so i turned it off and pushed down on the wire and I felt it click when I turned it on it worked normal till the next day & it started again. Talked to the guy at the TV shop he said that was not my problem that it was when I moved the wire to the flyback that I was moving the circuit board. He said I had a bad connection on the board from the horizontal chip. Before I take it apart and start checking sodier joints has anybody got any suggestions. Thanks

Re: TV goes black at bottom and has horizonal lines in...

Hello, please check the high current area around flyback transformer, horizontal output transistor as well as the deflection connector for bad soldering. Best regards, Arpi If you need more info please advice.

I have a Sony FD Trinitron 27' Model # KV-27FV310. It is approx 8 years old. After turning it on and watching a full screen for a few minutes; all of a sudden, a line came across half the screen;

top half missing is in vertical circuit of set---if it is a 27 inch and this old consider retiring it and replacing----other option is consider having a shop repair it--a rough guess would be as high as 150 dollars parts and labor is possible for your problems.

My Sony trinitron tube Tv 36" seems to be going (its 10 years old

no ....the tube will end up after 20 yrs in 10 yr old sony...
it is worth if u fix it. randomly going black means...horizontal driver trans former is the problem..or any loose contact with the 110 volt supply to that transformer,,or any loose contact with line o/p transformer.. (horizontal driver transformer may be gone
then tv behaves like this) if any other parts gone tv wont come back.... there may be a loose contact call a service pro..

Blackout area on screen

Make sure the TEXT and CAPTION options are turned off.

I am not sure about the Sonny's, but on my Toshiba a black box appears when I inadvertently leave one of the close captioning (CC) on for text or captions on (such as CC1, CC2, etc.).

Sony trinitron 32

Hi, tubes getting tired, band-aid fix you can do is remove back of set and turn up(clockwise) the screen control( small black plastic control mounted on side of flyback transformer, do not turn the knob marked focus) until you see a whole bunch of white lines across the screen, then turn same control counter-clockwise until all the lines go away, try several different channels to be sure all the retrace lines are gone, you`ll get up to 1 year more use out of it, than she`s done, good luck, BMW Rider

Thin horizonal line in middle on dark screen

The several thin white lines at the top of the screen is the warning that the vertical output IC is not getting the boost voltage it needs to run correctly. The IC cannot operate for long like that and shorts out inside, which is when the vertical collapses altogether and you get the thin white line through the center of the screen. The good news for your son is that he had nothing to do with that, and it has nothing to do with the cable F connector. The set needs to be serviced by an experienced tech who will restore the boost supply and replace the vertical output IC, and when I do that I charge $75 but techs in your area will vary, so be sure to ask around.
