Sony Trinitron Model KU-27TW77 Manuf. date 11/93

Problem Once in a while, while watching TV, the screen goes black for a sec and then it comes back. I have just noticed it happen over the past month. Background The TV picture has looked good for the past 13 years except for one repair about 6 years ago. Can't remeber what it was. Nothing but a TV Antenna used. TV located near a window. Thanks for any help

Blanking in a sony like that is usually a result of a weak CRT... You can turn down the G2 and it may help for awhile, but the blanking will eventually get more and more pronounced over time. I wouldn't suggest having the tube rejuvenated either. That usually doesn't last and a shop may charge quite a bit for the effort. You're better of buying a new set.

Sony Trinitron KV-27TW77 will not change channels after setting up auto program. Remote or TV will not change channels.

You have not cleared the number of programs tuned in the auto mode,if only one program is tuned than only remote or TV will will not change channels,check by tuning with cable connection with multiple programs,you will get the solution.

Sony Trinitron - Picture Disappears

Hi, IK circuit is engaging which basically means the picture tube is getting tired, the only "fix" is temporary (may get another year out of it). You have to increase the "screen control clockwise".
Remove back of set, follow large black or red wire attatched to picture tube down to the flyback transformer, mounted on flyback are two black controls, one is focus (leave it alone) the other is "screen", adjust it clockwise approx. 1/4 inch, remember that this is a high voltage circuit so use one hand in the set the other hand out of the set at all times,any questions ? e-mail me back, good luck, BMW Rider

Sony Trinitron experiences

The screen control inside the set may be on the highvoltage transformer or on the crt socket; either way if you can turn it up just a little clockwise and the picture comes up but doesn't look good you are likely to have a bad tube. Or try tapping lightly on the glass neck and watch the picture as you tap. If it reacts to the tap you have a bad tube. but the turning the screen control is the best test. Turn it the other way the picture goes off immediately. bad tube: too costly if it is available.

Sony Trinitron KV-32S40 32" TV problem

This is a simple and common problem. The solder joints on the vertical output IC have cracked loose. I actually did a housecall on the exact same set with the exact same symptoms this morning! A good tech will resolder the pins of the vertical output IC and all other major solder joints on the main board and the set will play fine.
