I assume that its there regardless of of which screen size you select.

If that's the case, it will be a problem somewhere in the optical light path. There are a couple of things in there that can fall into the light path. One is a defective light tunnel, another is something as simple as the mirror falling out of place.

In any case, you'll need to call service for this.

The picture tube could be getting old.

You can try to de-gaussing with a high voltage gun.

Sometimes when we are wearing tight clothes and put mobile phones in the pocket, the screen gets pressed against coins or keys in the pocket. This damages the screen. I think this is the case with you. Now, the only solution remaining is replacing the LCD.

The screen is dark no picture at all.The blue light is on indicating there is power.But there is no picture or sound !!!!!????


The standby 5vdc power section is working but the rest of the power sections (5vdc, 12~16vdc, and 24vdc) may not be working.
That will be the first place to look, look for caps with leaking/bulging tops.
