Question about Sony Televison & Video

Open Question

I have a Sony Trinitron, Model NO: KV-27V22, August 1997 that we bought sometime in 1997. Our present problem with it has been the screen flickering. At first when the TV was first turned on the screen would flicker between being normal for a few seconds (showing whatever was on) and a black screen which would last for only a second and eventually it would stop flickering altogether and maintain a normal screen. The flickering seemed to be affected by how bright the screen was and would flicker more often when it was brighter, say a scene during the day in a movie would be more light which brought on more flickering and a scene at night would be less light and the screen would usually remain normal. Over the past month that flickering has gotten worse to where it flickers between normal and black with just a second on both and it doesn't stop. The stand by light has stopped being on as well. There are no odd or different noises while the TV is on. It still clicks when the screen comes on after the few second warm up.

The vertical output IC has failed/Power to the vertical IC is out/ or there is bad solder on the pins of the vertical output IC.

SOURCE: TV switch light flickers 11 times but no function

Hopefully it is only a board component that needs replacing and your dry joints that need re-doing. I would advise that you take it to a television repair shop as this type of repair can be very complex (replacing resistors and capacitors just to name a few).

How do you know if your tv is digital?


When your TV has a digital tuner you will see channels like 2-1,
4-2, In other words you will also see channels with hypenated numbers.

Sony FD Trinitron Wega model KV-34BR800


Sony Wega Triniton KV-32FS100 TV

For the last week my TV has been going to a black screen for 10 seconds or so then the picture returns. It has been continual. Last night it stopped going to black screen, but now the standby light flashes 5 consecutive times and the color went haywire. A lot of red and everything that is suppose to be black is green.

I did a soft and hard reset with no success. What's wrong and is it worth fixing? Bought new in November 2002.
