Check its video output card for any loose solder terminals. This card can be located at the neck of the picture tube, directly plugged on to it.

You likely have bad solder connections around the tuner area. This model has a history of problems in that area or the tuner itself.

SOURCE: 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

Our Trinitron KD-27FS170 Tv will not turn on. It sounds like it is turning on/off but no picture or sound. The Stand-by/Timer red light is flashing 4 times, pause, then 4 times, etc.


This typically means you have a bad capacitor, you can inspect for any swollen or bulging capacitors however unless familiar with desoldering boards best leave it to a repair technician.

Retrace line with picture in sony hw21, m83


There are two possibilities fof thie fault. The fist one is with increased screen voltage. The second one is with fault related to its vidio output stage circuits. Video output stage circuits are at the picture tube base card. You can see this card plugged to the back of the picture tube. To describe more by this window is impossible, as there are illustrations must be included here. Just visit this site "Electro-help". It is an electronic equipiments servic ehelp site, has all the details about this fault.

Do I need a converter box for a Sony KD-27FS170?


When a TV hasn't digital tuner, it's necessary to add it a digital to analog channels converter box, but your TV already has digital tuner, you can switch between digital and analog tuning by pressing the digital/analog botton on the remote control.

Picture image does not look full when showing people


There is a service menu adjustment. I have seen several of these sets with bad components in the horizontal width control circuit. maybe your other set has a width problem. put both on the same channel. like cnn with the ticker on the bottom. what is the difference in size?
the width adj. procedure is: with the set off. use the remote, enter. MENU>5>VOL+>POWER . the set will come on in the service mode. then with the menu adj. buttons you can step threw the service menu to H.WIDTH adj. until full picture. also VERT. HEIGHT. when you are done adjusting make sure you press the mute button and watch the word WRITE flash from green to red or you won't save your adjustments.

Double picture


Can you give more details? What do you mean by Double picture? Do you have 2 pictures side by side or One on top of another? Or is it like a shadow behind the main Image? If it is a shadow (Ghosting), check your Antenna - connection, direction, etc.

NO picture


You didn't say how old your set is, but if it has a picture tube, then this may be you trouble. I've seen several Sony's do this. I've had several come in to the shop and set and play for several days and then "wink" out! Sometimes, though, the high voltage circiut will shut down and the sound will still work. I would advise you to have it checked at a shop. If is very old you need to get an estimate. Stargazer
