TV's have a built-in power supply (Switched Mode Power Supply - SMTP) to convert 110V AC to the required DC voltages plus the Extra High Voltage (EHT) for the Cathode Ray Tube (CRT). If the fuse is OK and both sound and video are not present, then the fault is almost 100% with the power supply. Some older TV's have a fusible resistor in the SMTP that "opens" whenever there is over current - check a thick resistor (usually a wirewound resistor)in the SMTP to see if it is open, Other faults that I haev discovered are the power transistors in the SMTP (usually there are 2/3 MOSFETS) - check id these are shorted or open using a multi-meter. RepairFAQ is a wonderful site that gives a lot of info on this - if you arehandy with a soldering iron and a multi-meter, this is the site for you: http://www.repairfaq.org/sam/smpsfaq.htm . If you are not hands-on, don't waste time trying to get it repaired through a repair shop - you will spend as much on the repair as you would on a brand new TV. And LCD TV's are falling in price - you can even buy a 20" LCD display for $170+ and an external tuner for $50 - or a fullfledged LCD TV for $300 .... Good luck
If the deflection yoke is rotated it can cause a slanted TV picture. The deflection yoke is located on the tube neck inside the TV.
Why not!Smashing the face of the picture tube will cause an implosion.
the tube has gone. its the second most expensive part of a tv after the screen.
Cause of Concaved Picture It sounds like you have a bad capacitor somewhere in the vertical circuit. As it ages and dries out, it changes value, and usually in the wrong direction.
Depends. People say true LED TVs give a better picture over the traditional LCD TVs simply cause it covers a more wide area. True LED TVs are made with higher resolution then normal TVs of today.
I had this problem where the Fios remote control stopped responding to inputs on certain screens like the DVR, menu, or program guide screen. The issue was infrared interference due to the Panasonic TV picture mode. If you have a Panasonic TV and the picture mode is set to VIVID it can cause this issue. Set the picture to a different mode and you will be fine.
In the analog days, a weak signal level would allow this to happen. Objects moving near the receive antenna could cause the incoming signal to arrive at the receive antenna at different times causing ghost, reflections and a jumping picture to appear on the tv screen.
The problem you describe might be the tube, but there are other parts of the television that can cause similar effects. You will need to have it checked at a TV repair center and they will also be able to tell you how much a new tube could cost. In these days of very low cost televisions, it is quite likely that the tube will cost more than a new television.
Television does not cause blindness.
TV does not cause asthma.
Sony have a far better tv, the picture quality and features far outweigh the aesthetically nice looking samsung tvs!! Also it is hard to comprehend why samsung would cause screen shadowing to make the edging slimmer.
You probably have it set for non-interlaced picture. A non-interlaced picture scans every line on the monitor in sequence and this can cause flickering. Setting it to interlaced will cause the raster to scan every other line and then go back and scan the lines it skipped on the first pass. Televisions do this routinely to prevent flickering but its user-selected on computers.
Yes, a bad tooth can cause sharp pain in the head.
yes DVT cause sharp pain in the legs
The biggest offender would be a Cathode Ray Tube picture tube in a traditional TV. I am not aware of any house hold appliances that would fall into this category. Even in a CRT TV you wouldn't get shocked by touching anything outside the TV, like the power cord. You would have to be messing around inside with the picture tube. However, from personal experience I was thrown across a room by messing with an unplugged TV picture tube.
Although not written for TV (before its appearance) the first TV play was called 'The man with a flower in his mouth' And was broadcast on the Baird Mechanical TV system in London in July 1930. There was very little action as rapid movement would cause havoc to the picture.
A sharp needle.

One reason is the refresh rate on the monitor. instead of a steady picture, it is always flashing so fast you can't see it. This is one reason why watching tv on your computer is harder on your eyes than on an actual television.
No, it does not cause cancer. In fact, it's impossible that TV cause you cancer. It only causes you bad eyesight if you keep watching it too much
