crt burn in

when looking in the dump I will often see a television with horizontal line burn in and some thrift stores have tee vees that when you turn them on all you see is a horizontal line. How come you never see a vertical line.

if the horizontal fails, so does the high voltage, so you see nothing

As another poster replied, horizontal defleciton is related to high voltage; you rarely have one without the other.

Vertical deflection has a lot of components driving it, and bad solder joints are a very common problem after a TV is several years old. But horizontal deflection failure, when it does happen, is usually caused by a bad connection on an inductor or a connector. There are just so many more opportunities for failure in vertical deflection.

Sometimes, when viewing a pile of TVs at the thrift shop, you'll see phosphor burn along the top of the screen. This is caused by failure of electrolytic capacitors in the vertical deflection circuit, causing a problem called "foldover." The electron beam is drawn more often in the topmost section of the tube than it should be, leaving a burn.

The horizontal line and foldover line burn in on the phosphor is 99% of the time not the direct cause of any internal failure of the tv set (except for RPTVs). Since it typically takes considerable time on a direct view tv set for burn in to occur, the burn in is caused by someone using the tv set for extended hours in the fault condition.

This is because there was a vertical deflection failure of some type, and the user left the set running. After the set is serviced, there is a scan burn in the phosphors of the CRT. This type of damage is not reversible without putting in a new CRT.

How come you keep swapping servers, s*****ad?? Now on an anonymous denmark server.

More importantly, how come you haven't been on for a week?
