You have a frame collapse, if you had previously been tapping it to come on then it sounds as if there is a dry solder connection most probably on the frame IC or surrounding component. If you are competent with the use of a soldering iron, then remove the back & gain access to the underside (circuit print board) of the TV. Look for an IC that is attached to a heat sink & carefully resolder the pin connections. Look closely at the surrounding solder connections & if any of them look dry then re-solder them also. Without knowing the model of your TV then I can't be more precise as to the specific component location. If you do not want to attempt this then a local repair shop should be able to easily fix it for you.

Sanyo LCD 40" Tv ha a horizontal split in the picture on screen. Split looks like a horizontal line with a red tinge. What could the problem be?

I hope it's under warranty, that sounds to me like a liquid crystal bleed, they nearly always start in the middle and are terminal, I hope I'm wrong.

Have the horizontal line but by tapping ( lately smacking) top or side of set,picture will resume. Been getting steadily worse.

Issue ...with Connection.. Check IC Logic Regulator..Possibility Over Heat ..Also check Capacitor for leakage Check Horizontal Holder for bad Resistance signal..

We have perfect sound but only a thin horizontal line in the middle of the screen.

this is a capacitor that has gone bad in the vertical delfection stage of the tv. it is an very easy and cheap fix if you know someone who knows how to solder and replace electronic components. If not then you'll just have to get another tv as taking it into a tv repair shop is not worth the cost. You could get another tv for what they will charge you to repair it,

Time to time I get only a horizontal line on picture tube of my 26" Sanyo TV

take it apart, there will be a chip like la7835 (then number might be different) it will be an upright chip. 7-15 pins. solder it. if you cant find the chip take it apart and turn it on and tap on all the heatsinks and the line should appear when you tap the vertical chip. then resolder it, and if you want it to last longer replace the 100@25-50v capacitor next to it

Flickering multi-colored line in the middle of the screen.

You have a failure in the vertical deflection circuit. This could be either a bad vertical chip, the power supply that runs the chip or a bad capacitor in that circuit. This is usually a repair best left to a professional. There is a small possibility that it could be bad solder connections. If genlty tapping the unit temporarily solves the issue you can try and resolder the pins on the vertical chip LA7841 is the part number. There is also a resistor 1 ohm 1 watt. If that resistor is open you can assume the IC is bad

Horizontal blue line

The intermittent horizontal line is cause by a loose solder connection in the vertical amplifier IC.
The IC is mounted on a heatsink nearby or around the flyback transformer.
The way to fix this failure is to add fresh solder where you see some brown spots on the circuitry that were cause by components getting hot.
Good Luck.

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!
