Re: snow screen

Your symptom is not a normal failure symptom. Can you be more specific? Is this on all inputs?

Screen has gone grey and has fine horizontal lines on entire screen. Blue screen is out.

Either the screen voltage to picture tube is more than normal, or the video processor IC has damaged. There is an other possibility that there is no voltage at the video output card, plugged on to the neck of the picture tube. Anyway, your set need a through checkup, and the work is somewhat skilled one. Just check this site. Soemtimes you might get some details about this fault. The fault is called vertical retrace lines. Thin horizontal lines all across the screen with an inch apart. One among the posts published in the following site have details about this fault.
Visit the site named 'Electro-help' for more details. Click this link. View it in "Timeslide" or "Flipcard" option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. It will make search easy.

My tv made a little noise and then the picture disappeared. The screen is black with a vertical line of picture approx 1/4 inch wide going up the middle of the screen. Is it fixable?

Generally this is not good news. Even in the event this TV is repaired, it will work very long. This TV has a horizontal problem. This is the most stressed area of any conventional TV. The Horizontal Output Transistor will need replace, the flyback transformer is bad, you have bad power supply with horizontal capacitors that are bad, and last, is a possible bad picture tube. This TV is not worth the effort or money to repair. Thanks for asking and show all hands of support!

Phillips 28in wide screen tv. Picture OK through Sky, but has two moving distortions on ordinary aerial. Actual picture is good but the distortions moving up the screen make it very difficult to watch.

Even digital signals can be sensitive to electrical interference and using an antenna, you could be getting garbage from any nearby 'noisy' source. Something you might try is to temporarily switch off any electrical device in your home, one at a time and look for changes in the banding you have.
If the antenna you are using is outside (rooftop) and is rotor equipped, try changing the position to see if there is any increase or decrease of the problem. If an indoor antenna, rotate it slowly while watching the TV display for change. You may be able to determine the general direction of the source of interference. Some seemingly innocent devices that can cause problems; - Light dimmers/controllers - Poorly designed network routers - Cordless phones - Power supplies

Kv-35xbr48 turns on fine nice picture then horizontal lines form distorting picture like interference also is the back hard to take off and put on needs a good vacum thanks for any suggestion

At first the picture is ok, and then distorted with horizontal lines i thinks. If the horzontal lines are parellel acros the screen, with an inch apart across the whole screen, your tv needs screen adjustments. Screen voltage may be high. look into the crt base also. Change it first. These also not resolve the problem, LOT may be faulty, with respect to screen focus pack. May need replacement. Try first setting screen voltage to a lower settings and observe.

Ps 27123 have sound, tuning etc only small horizontal color band

Hello bdedrick708,

If what you are trying to say is that you have a 1/4 inch horizontal line across your screen, this means that something in your vertical deflection circuit has failed. This could be the vertical oscillator, the vertical output processor, the vertical coupling capacitor, or the vertical section of the yoke transformer.

If what you are talking about is a vertical line from top to bottom then you are possibly talking about a failed horizontal section of the yoke transformer.

Why so little about the horizontal section of the yoke? That is because if the horizontal section fails completely then you would lose high voltage and no line would be present because you would not have raster (screen light).

In any even check the yoke transformer first. Then work back from there.

I hope this helps,

Thank you,

Check for leaky capacitors in the vertical section of the TV or cold solder joints.
I would also check in the power supply.
Good Luck.

Not likely convergence because it's simply a direct view TV. Could be vertical, a common problem with that unit is the vertical output IC Q301 and poor solder connections of the link off R305. This could be enough to put the unit in shutdown. And it could also be SMPS, possibly regulator or horizontal output transistor - you would need to test these to be sure. The HOT, if shorted, will have continuity E to B or E to C.. If you're not sure you're up to this take it to a reputable shop. What I've described above isn't too serious and a good shop can having back to running good as new in a couple of hours. One tip I might add, take to the shop yourself it will save a few bucks. Good Luck Bill
