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 beappreciated. My model is a KV40XVR800 this is not listed in the drop down product menu so I just picked the closest one. Wade
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.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.

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.
Have you when set turns off and standby or power light flash to count here the blinks if in a sequence like seven blinks, pause etc? This se should have the error buffer.
Hello,
Does it blink seven times, pause, then seven times, pause, seven times, etc. ??
If so you may have a bad heater element. Or the water temp into the D/W is not hot enough. Most machines require at least 120 degree water to work properly. Take a close look at the heater if it looks ok you'll have to check it and the heater circuit with a meter. Turning the breaker off for 7 to 10 minutes will reset the control board but wont fix the heater of course.
Good Luck
if you have the circuit diagram of your tv,check the horizontal polarisation IC closer to the line transformer and replace it.If it doesn't work,send the question again.
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.
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.
7 times blinks shows problem in Horizontal Deflection stage of tv and possible defective part can be Horizontal Output Transistor or Fly back Transformer.
If your are qualified tech person then go ahead to check above parts.
Does it blink a certain amount of blinks pause a second or just blink constantly with no pauses? Let me know it will blink a code if its going into protected shutdown. And it will blink constantly for another reason.
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.
