TV video problem

I have two TVs both started showing a thin compressed picture in a horizontal line across the screen. I have used different cable outlets, disconnected all my other equipment but the problem persists. My smaller (and older) Sanyo will occasionally work for brief periods but there is nothing consistent going on. Cable guys came out and said it is electrical interference...what now?

Re: TV video problem

If you have intermittent line horizontally across both tv screens then there is likely to be bad solder connections on the vertical ic's of both of them. This can be fixed by taking the back off with quarter inch nut driver and carefully sliding the chassis out and turning it up to see the solder side. I don't know the location numbers but the vertical ic will be mounted on a metal heat sink and the connections will be in a row. Sometimes you can see the bad connections. You may need a magnifying glass. I recommend someone who has experience soldering electronic circuits. No solder bridges etc. This is for intermittent (works sometimes) problem on vertical ic. If the line stays then the chip ic is bad along with a 1 ohm resistor off the flyback high voltage transformer. From what you described you likely have bad connections. Hope this helps

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.

Black line running horizontally across TV screen

A line on an LCD, either horizontal or vertical usually means the video driver board is defective or the screen is defective, does it show up as black even on a dark screen? That means a line of LCD "shutter"s is not working and there is a problem that cant be fixed by a reboot or channel change. Bummer.

Tube TV - one thin horizontal line of bright light

Vertical defection failure. Common failure. Pretty easy to repair ($50-75?). However, my general rule of thumb is not to waste any more money on TVs over 10 years old. Too much other stuff in there ready to fail as well.

Tv not working

this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!

Horizontal 'pinstripe' lines on all channels

sound like the screen control on the flyback is set just a little too high. the flyback has the red wire attached to the tube. the flyback has 2 small adjustable controls. if you look close enough 1 is marked focus & on is screen. turn the screen slightly to the left & look at your picture. the screen is like a master brightness & if it's up too high you will see what is called retrace lines. good luck.

Top section of the picture gets reversed and compressed

Dear simon, Seems like a simple problem. In all likelihood, one of the Electrolytic Capacitors in the vertical Output stages has failed.It could also be a cold / dry solder, as symptoms seem to disappear when you tap the set. But, do not try anything thing at home. A proffessional Techie should fix it up in 15-20 mins. Definitely worth the spend.
