I seen 2 post with same problum diffrent explations, I have the same TV with the same problem. I am sorry that all the answers are so silly and basic. I just open up mine to check all the compositors to see if their are any Bulging or to see if anything looks damage. I will pull the Power supply and start checking the compositors. and let you know. I will look in other places first to see if I can get some REAL Answers. Poco Zocko Actor

    OKAY I found the Problem!! Bad Caps Compositors. I Proved this in 2 ways. First I took off the Back(always make sure the TV is UNPLUG) In the photo above I put my finger on the capacitors. I found some that where NOT FLAT ON TOP(You can kinda see in the photo too). I could feel a little nipple on top.(Some times you can see if their busted open but not in this case) so I felt them and the bottom right and top left area in red in the photo where not flat. I took my dryer(My wife really) and warmed them up for about 2 minuets each then another minuet rotating back then forth. I leaned the t.v. up to lea on the frame and plug it in. I continued warming the capacitors up and in about 2 Min the T.V. has stop blinking. Much better then the 20-30 min. So the hunt for the Capacitors is on. It will be some work to get the boards out. If everything is done delicately The Soldor job is easy for me. I am going to buy the 8 but replace 1 board at a time until the TV works and put the other on the side for next time or put them up on E-bay. I hope this helped Please like if this helped you.

SOURCE: Vertical colour lines on whole screen

The problem is that the panel has failed. Apparently this is a common problem with LCD TV's between 18 mths and 3 yrs old. If it survives over 3 yrs it is likely to last for a few years longer. The cost of replacing the panel is more than a replacement TV!

SOURCE: A fine green vertical line displayed on the Sony Bravia 46.

Thats a pixel data problem, there's no data being sent to that row of pixels so they don't change color. This is a pixel address registry (PAR) issue and the PAR circuits need to be serviced its usually due to open or shorted SMT components on the PAR circuits. PAR also sends data, voltage, and control to each pixel, the green line you see are pixels that have voltage but because there's no data sent too them their all green because there's no control. If the pixels have voltage but no data or control they show up as green red, blue, yellow, or whit line vertically down the LCD panel. The vertical-horizontal section of PAR are controlled by 16 to 32 bit micro-controllers which may need replacing. If its under warranty take it back if not have your local repair center fix the tv for you...

If the screen works for a short while and then completely fails once the TV warms up you have a problem with the main unit video board or the LCD control logic board. Most often if the picture cuts out but audio continues to work the logic board is over heating and should be replaced. However if the picture cuts out and audio shuts off as well then its your video input board.

Tv has horizontal line in middle of screen,sanyo ds25390


hi if only a horizontal line across with no video anymore, you have bad either vertical ic or no dc supply b+( vertical ic ) or no output dc coming from the ic. if it is not totally a horizontal white line and you can see a video you must check leak or bulged capacitors at the vertical section near the vertical ic. hope this can help good luck.

Tv screen is black except for 1 horizontal line of color


The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv .

6 horizontal lines


I would look for a Vertical circuit failure. Most likely is the vertical output IC and or open resistor off the hv transformer. Definitely look for any loose solder connections around the Vertical output IC.
Hope this helps,

TV: bright line across black screen for several hours.


vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch

Sony rear projector TV problem, KP-61v35


This is a problem with the vertical circuit. This can be as simple as poor connections at the vertical IC or a defective IC. If you can solder, you should be able to fix this yourself. Let me know if you wish to attempt the repair and I will supply additional details and instructions.

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!
