Question about Sony KV-32S45 32" TV
I have sound and the picture will come on but will go back black and keep flashing back and forth how do i fix it
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.
