Television Problems




I was watching my TV, when all of once it just went to a line across the center!


One of two things in general: First, if the TV "popped" first, then went to a line, turn the set off for a

about a minute and then turn it back on. If your picture returns, you just had a picture tube arc and

the set went into a safety shutdown. If this problem persists, you probably have a picture tube

going bad, especially if the picture when the set "pops" goes green, red or blue first. Second, if

when you turn the set back on and the line is still there, you have a component failure and it is

probably worth repair by a reputable service department.


The TV just every so often goes off and may come back on by itself.  When it goes off, I can tap on the set and it comes back on.


This problem should be taken care of as soon as possible.  This can lead to more serious and expensive problems.  If you wait until someday, when it doesn't come back on again, you've waited too long.  If it happens to be a 27" or larger screen, the repair is feasible, but not for the smaller screen sets.


I was watching my TV, it popped and went dead. After turning the set off and back on, it was still dead! I unplugged it, plugged it back in, attempted to turn it on and was still dead!


This is "muchly" dependent upon the manufacturer, but either way or whatever, you have a

component failure, that can amount to being worthy of repair, to mostly junk as far as the cost of

replacement would compare. Take your set to a reputable service department for a "diagnostic

fee" estimate and get the facts about your failure. This fee should come off of the final bill and the

set may well be worth repair, either way you will know for sure.


The television picture intermittently goes to "snow", or is "snowy" all the time!


There are multiple situations here. If the set is "snowy" all the time on all channels, play your VCR on

your TV and see if the picture is ok. If it is, you more than likely have an antenna, cable or satellite

problem. If the problem is intermittent, you can have a tuner, tuner control, tuner circuit component

or circuit board solder connection failure. With any of these, you will have to get an estimate to find

out what. In most cases, replacement of the tuner is prohibitive, whereas repair of the chassis is

worthwhile.


There appears to be some horizontal lines at the top of the screen and the picture may be distorted there also.


There is a good possibility that a capacitor has failed in the vertical circuit.  Which one depends on the make and chassis.  This is generally worth while to have repaired, especially if the picture was good prior to this problem.


The picture is short or pulled up at the bottom and distorted or non-linear in its appearance.


There is a good possibility that a capacitor has failed in the vertical circuit.  Which one depends on the make and chassis.  This is generally worth while to have repaired, especially if the picture was good prior to this problem.


The picture appears to be too wide or too narrow and if in the too wide situation, shuts off sometimes.


A capacitor has most generally failed in the horizontal output circuit. This is generally worth while to have repaired, especially if the picture was good prior to this problem.


The picture is too narrow and bowed in on the sides.


A component has failed in the pincushion circuitry.  As only the larger screen televisions incorporate pincushion circuitry, this failure is worth while.


The television seems to "hunt" (sometimes apx. 3 times) when changing channels.


There is an aft component failure or alignment drift.  Unless the TV is old or has other problems, this failure is worth repair, by a competent service center.


The buttons are pushed in on the front of the set.


On some televisions, the buttons are too expensive to have replaced as they are part of the complete front panel.  If the TV is of the larger screen size, then the mask replacement should be considered.
