Most likely this is a case of bad solder connections to the TV's vertical output integrated circuit (IC). This part gets pretty hot while operating, and it's very common for the connections on the circuit board to get flaky from the heating and cooling cycles. A few minutes with a soldering iron by someone who's done electronic soldering is usually all it takes.

It's also possible the output IC has failed, but the bad connections are far more common. I have no idea what a service shop in your area would charge to make the repair if you don't feel you can handle it, but it would certainly be less than the cost of a replacement TV.

Don't continue using the set with this loss of vertical output. The picture tube phosphor surface can be burned by the narrow bright line, and leave a dark line in the picture after the set is repaired. There is no way to repair that other than replacing the tube, and that WOULD be more expensive than a new TV.

My crt acer ac512 monitar only centre line view,c"not full view why?


there are several reasons why picture of crt monitors did not display good picture. if your monitor had horizontal line at the center of the screen?...the faulty is in the vertical deflection, check the vertical oscillator also the fusible resistors & capacitors around that section. if there had vertical line at the center of the screen?..check the horizontal deflection, horizontal output transistor also check the YOKE.

Horizontal lines shadowed / blured picture after 20-30 minutes


There are some semiconductors or capacitors that are leaky. Might need thorough check up inside the TV.

We have a 27" MTS Stereo color TV. There are white horizontal lines at the top of the screen. We do have a DVR with Direct TV. How do we fix?


U can't.Only horizontal lines on the top parts of the tv screen or the lower parts of the picture screen.Or very light horizontal lines mix in with the tv screen pictures.The "CRT" the picture tube is slowly dying of old age.Quicker than they supose to.The late 90" these problems case show up alot more in standard tvs using CRT tube.Because the CRT and analog design about to be faze out of the market place.The glass molding and those radiation matrials,they used to make those "CRT" picture tube materials,not as good as before.

Three coloured lines appered on the screen - no picture


If there is no picture and 3 vertical lines in the center of the screen, stop. Turn off TV. You have no horizontal deflection happening. Lines will burn into crts and be permanently visible after repair.

No horizontal deflection is caused by Horizontal sweep circuit failure, maybe flyback transformer and associated components. More than a simple do-it-yourself repair.

Faint horizontal lines in picture


This is usually caused by a problem in the Horizontal Output section, around the Horizontal Output transformer usually a capacitor or diode going or gone faulty... the line you see are the Horizontal "Retrace" lines that are useually "Hidden" when the circuit is OK..
