Question about Sony FD Trinitron WEGA KV-36FS120 36" TV

1 Answer

No picture, no sound

My stand by light blinks 7 times, pause and then seven more times etc. The TV worked fine, we turned it off and now can not get it to turn back on. It acts like its turning on but does not. I've unplugged and waited 30 min. with no change. I did get the system to change from 7 to 6 blinks once. The set is approx. 5 years old and it took four grown men to move it (almost killing one guy) so taking it to a service center is out of the question. In looking at this site others are having same issue. Any help would be appreciated. My model is a KV40XVR800 this is not listed in the drop down product menu so I just picked the closest one.

    We have the same exact problem, except it blinks 5 times. This just happened last week, and the TV is too big for me to move.

    Sorry fat fingers, it is an XBR not an XVR. I left it unpluged over night and when I got home pluged it back in, it worked. So I kept it on for 3 hrs and then turned it off, wiated 10 sec. and tried to turn back on, it workes!. The day it was giving me problems was very humid, real high dew point and the set is next to a window. I'm suspecting that this is a short term "happy time" so this week I will try and get it out of the corner and the back off.

I don't have a listing for your model, so I'll need to research this one a bit. The 7 blinks usually mean a high voltage shutdown though. Check the regulator IC on the power supply board. Once I find the manual for this, I'll try to get you more specifics.

    Look for poor solder connections on the main board. If you can solder, resolder any connections that appear grainy or have rings. That may resolve the problem even for humid days! :)

    Keep me posted.

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.

I have a sony wega trinitron, when the tv is turned on, (no visual, or sound) the red stand by light blinks 7 times, and you hear the tv click off? Please help


Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

Seven blinks, pause, seven blinks, etc. means "Horizontal deflection stopped" and indicates a serious problem, probably on the D or DZ board (whichever is applicable).

If this is the case, the TV will have to be serviced by a professional.

I hope this helps :)

Sony Vega Service Codes


KV-32HS510 and KV-27HS420, seven times blink error code shows problem in Horizontal deflection circuit.

There are many possibilities like dry solder joints, weak capacitors, Horizontal transistor short or flyback transformer fried etc.

If you have little experience of TV repair and good solder skills and have necessary tools to test / check defective parts, then you can make it. you also need to have related service manual to see board location, schematics and part numbers.
