    I have the same problem as well. I tried adjusting the top adjustment with no luck. A few things I noticed.

    When trying to press different buttons on the remote I find that the screen will stay on for a little longer when certain buttons are pressed, otherwise, the screen continues to blink.

    When the tv is first turned on there is only a black screen, then it will start to blink faster the longer it stays on.

    The place that you hook up the cable turns when tightening the cable to it once you get it just tight. I can turn this cable hook up on the tv by hand. I don't think it should turn.

    I hope that this helps to solve the problem.

    Thanks

This can be a sign that the picture tube is starting to fail. If you feel comfortable working with the back off, try the following:

With the back off, locate the flyback transformer (part with large red wire coming out the top). There should 2 adjustments available on this transformer. Turn the top one (screen control) slightly clockwise, this should allow the set to work as expected. If that is the case, the picture tube is starting to fail and the adjustment has bought you time to find a new set. The lower control is for focus. Note: if you turn the control too much, the picture will be really bright and you will see the retrace lines as well.

Keep us posted.

Sony kp-61hs10 tv, has sound but picture goes black after 3 min.


I just had the same problem. If your lucky it might be a free 5 minute fix. The five light flashes mean impropper current. I took the front grill off, then behind that is another black cover, I took that off and noticed the circuit boards COVERED in dust. I then took an air can duster and blew off all the dust... works like new. No more flashes and in an out picture. The collection of dust was interfereing with the electrical current.

Screen keeps flashing on and off


If the sound goes off too then there are bad solder connections, if it just the picture then the picture tube is getting weak, some times a picture tube rejuvinator can bring some life back for a while.

TV Picture Goes Black


I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions

Sony tv picture keeps flashing


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