Picture Would Come In and Out, Now Not at All

At first, it would take a few hours before the problem would occur. The picture would go out, and then almost immediately come back on. Over. And over. And over. Turning the TV off and then on again would be no use immediately, but it seemed like I could let the TV "charge" and after 5 hours or so, I could back to square one, where it would take a few hours before the flickering would begin again. Over the last two weeks though, it has gotten worse, to the point where now it's roughly 5 minutes before it begins flickering, and then after a few flickers, it's off completely. The sound is still fine, but the entire video is gone. Any suggestions?

    I will say, and you can tell me perhaps if this is consistent with the problem you are suggesting, that now when I "smack" the back of the TV on the right side of the set, the picture often reappears after it goes black. But you are right, the picture is, I noticed, actually still there, just so dim after it flickers off that you can't see it (hardly) at all.

    Would you say that is the same problem, or does that enlighten anyone as to another potential solution?

It seems as though from your description it is just the brightness changing. The Cathode Ray Tube has three electron guns at the back end. These are for green, blue, and red. Each gun has a cathode and a grid. Nearly all control the brightness by having the grids tied to a variable voltage. And nearly all control the colour and luminance by an amplifier connected to each cathode. As you do not say the colours change the the amlifiers are OK. I would suggest the voltage to the grids ( or cathodes in some), is unstable due to a bad connection or a dry joint, or a faulty resistor in that part of the circuit. Very old sets without remote control used a potentiometer to vary the brightness. A voltmeter is all that is needed. When the picture goes off try holding the increase brightness for some time, to see if it reappears.

Hi

I think your problem is in the tuner, a metal box located near the antenna input. This tuner can be removed and serviced. Sometimes the tuner DC supply line is unstable due to a filter capacitor or zener diode generally rated 33V (most common) and should be the first step in troubleshooting process.

Static & Picture Loss via Coaxial Cable Input Only on Sony FD Trinitron WEGA XV-36XBR450


Hi
The problem may be in the tuner or associated circuit. Firt check the DC supply line to the tuner. This circuit has a limiting resistor (15K 3W) and a 33V zener diode. If these are OK the tuner is faulty and should be removed (sometimes it comes on a separated board attached to the main board) and serviced.

Sometimes the picture rolls for 30 minutes to one hour and then the picture is perfect. A few times when we turn it on, the picture is okay and then after a few hours, the rolling picture starts. Where is...


The rolling is a bad filter capacitor on the signal board in the set---Any Mitsubishi dealer can look the model up and see known faults including this one---some of the sets when cold---vertical jitter in picture or just menu---If the menu is stable you have a tiny bad cap= weak caps when cold act up and when get hot regain capacitance and start to work.

I have a tube tv. the picture as lines and is blur that goes in and out.


If the lines are colored DIAGONAL lines, they are referred to as "retrace lines," which indicates either that the picture tube bias is set too high, or the brightness level is set too high.. If the blur occurs when the image is particularly bright or a particular color is bright, it is referred to as "blooming." This is caused by either a weak high voltage circuit or because the picture tube bias is set too high.

Is the picture set very bright? Try reducing the brightness control to a level where the retrace lines disappear, and reducing the contrast control below the level where the blooming occurs.

If the television is more than ten years old or has many hours of use, the picture tube may simply be deteriorating normally. By nature, they have a limited life span. Before you decide to throw the set out, if you are technically-inclined, try adjusting the bias and screen drive controls for the television as recommended by the set manufacturer (you didn't specify what make or model the set is), and you may get a few months or years of additional life out of the set.

Picture goes off


A temporary solution is to unplug the TV for a few minutes, remove static from the glass with your hand. It is important to unplug rather than turn off. If you have a degauss button you can also press that before unplugging. Wait several minutes or an hour. Then plug it back in. If you have Picture in Picture it may be an issue with that and to permanently solve may need a repair person. The unplugging may get you by for a few days at a time. That's at least better than an hour.
