|
| How high pitch is the ringing sound? Do you feel any accumulated static when you wave your hand over the glass of the screen? Without hearing it, it pretty hard to guess what your problem is. But when I have no picture (or HT) , the first thing I check is the horizontal drive transistor. Good luck. Switch mode power supplies can squeel if the are not happy. | |
