Question about Sony KV-27S46 27" TV

Black vertical line on right side (intermitant)

12 year old sony trinitron had one inch black vertical line appear and disapear for 2 hrs. (only on right side)then it shut itself off. Could not get it to turn on again. Picture tube? I took the back cover off and there was an incredible amount of dust covering everything - blew it out with an air compressor but no luck with it turning back on. Is it time to put it on the curb with the trash? or simple fix?

Re: black vertical line on right side (intermitant)

Your problem sounds like the stk type regulator.. Itsnot a really expensive part BUT on a set this old yes you can repair it but also your gonna be repairing it more and more as the capacitors are drying up and the circuit is getting brittle. I wouldnt invest anything in this set. time to make a boat anchor out of it!

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.

Cross lines ontop of screen my G21 M1 tv.. pls tell me how to solve it

The vertical output section of your TV has the fault. Replace all the electrolytic capacitors there, including smoothing capacitor to supply line to IC. Check for any loose solder termianls too. The lines you are seing across the screen, on it tope side, about 2 inches might be due to this fault, and are technically called [vertical retrace lines].

My 12 year old Sony Trinitron KV-32XBR200 still works pretty well except that it cuts off about 25 - 30 scan lines at the bottom of the screen when cold, then gradually improves somewhat to missing only 15...

No,tv have cold solders inside the tv like vertical IC or around the area.Have a soldering iron,a roll of solders,also know how to do basic soldering?Yes.Take the tv aparts,take a back plastic of the screw driver tabs all around the main pcb,will see the vertical changes,take out the a/c power sourced,resolders those area,will fix this problems.

No picture appears on screen

without seeing the set this is a hard one to fix if the button is slack when you press it then the button is going to be the problem otherwise it could be a transformer that has gone in the set, 12 years is a good age for a tv so i would suggest replacing it with a new lcd or plasma.

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.).

Intermitant color bursts of red, green, purple


for the color problem,most likely you do have problem with loose contact of components from C-board ( small board connected at the back of CRT "picture tube" which drives every color and size of the screen)if you have knowledge with soldering electronic component parts, resolder this board and also check main board for possible loose contact.

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

Picture deterioration

Your whole problem my freind is dryed up capacitors. You should go, if you have the technical ability to replace these capacitors, to, download the schematic diagram, and start replacing the waveshaper capacitors in the vertical drive circuit.
