Both Convergence fault (malfunctioning convergence IC) and dirty sensor may be the cause for auto focus not aligning to presets. Another possible reasons is that presets are bad and must be set up with service procedure.

In all cases the job should be done by a technician, as it is easier that you cause more damage , rather then fixing the TV.

You can call technical support by using the number listed on your oner manual.

One possibility reason is The Sensors installed inside screen of TV can be dirty and not giving proper data to adjust convergence automatically.

These 4 sensors require cleaning by front screen taking off.

Tip

White Raster with thin lines; Sound Ok.


White raster with retrace lines: No picture, Sound OK
(picture tube based telivisions.)

It is a common fault to occur in most of the CRT based telvisions, regardless of which brand it is. There will be sound OK, and a bright screen with thin white horizontal lines across; at about an inch space, all over the screen area. This fault may occur along with colur shades also, like blue screen with white retrace line, red screen with white retrace lines, green screen with white retrace lines. Let us take the first case. A white raster with white thin retrace line acorss the screen. These are call vertcial retrace lines technically. To make it mor understand, we have to go to some picture tube electrode details. There are three colour cathodes for a colour picture tube, Red, Blue and Green. Two girds are there called Focus and Screen. Focus grid is supplied with focus voltage which in turn determine the cocus of picture, and screen grid is supplied with screen volrage which determine the emission of the picture tube; in short. There is a final anode to all the picture tubes, which supplied with Extra High Tension voltage, can be located at the top side of the picture tube, to which the EHT voltage from LOT is connected with the help of rubber ****** and clip. Without these three voltages, EHT, Screen and Fcous, no raster will be produced. Therefore in our case, there is a raster, so, horizontal output section including Line Output Transformer [LOT] is functioning well, and as far as sound is there, tuner and video IF section are working well. In fact, all other section except, video output section is working properly.
There are three cathode points on the base card, marked as Bk, Rk and Gk. Check the voltages of these three cathodes. In our case, it will be very low or approximately equal to zero. When cathode voltages goes low, emission of the CRT increases, is the reason. There must be a voltage between 120 and 135VDC at these points. Find out the reason for this voltage drop is the next step. The video drive voltages in most TVs comes from LOT windings, after rectification and filtering. There will be one reisitor of low value, say one Ohms or so, will be connected series with this winding, in between diode and winding. Check the voltage at the cathode of this rectifier diode first. If found low replace the diode and the smoothin capcitor. The smoothing capacitor will be between 33 and 47MFD 250VDC rating. Replace both of them. If there is volatge, say 200VDC or so, check whether this voltage comes to the CRT base board or not, If not, check the conducting wire, serial resistors; if used for open. There is no chance of transistor shortage at this time as the raster we see is white. If raser we see have a specific colour predominent, that is green, blue or red, check the revalent video out transistors and replace it. It is best to replace all the three video output transisors at the same time with same batch and number.

Dp50747 has vertical 2 inch wide black row with a green line up the center, which card might be at fault? thanks


If you have JUST two green lines then your choices are between the buffer boards, YSUS board (all boards on the LEFT side of the TV when looking from the back) and , less likely, the main or plasma controller board. I'd really focus on the first two.

if you have two lines ON TOP of otherwise normal picture then you most likely have a bad panel, specifically the address register ICs embedded in the display's fabric underneath the display ... there's no solution to that I'm afraid.

Lines down screen


We have a Samsung LE32A457, whilst we were watching T.V tonight the top halve of the screen suddenly appeared with green lines halfway down the screen and that half of the picture was unwatchable, T.V is 2 years old. We have removed all scart leads but this did not help and the problem still exists, when shutting down a white horizontal line across the centre of the screen appears from this line upwards the picture is faulty. Any help or advice would be grateful.

Green lines down length of screen on my samsung 40 inch LE40F8


The reason for the green lines are the resolution. I'm assuming you're TV is set at 1080i, not 720p or 1080p correct? What happens is the "i" stands for interlaced, meaning, your TV displays your images with scan-lines. The "p" stands for progressive, meaning, TV displays picture as a whole. You can not visibly see the scan lines when seeing 1080i, but certain TV programs are not outputting their show to the resolution you're at, which will cause you to have the green line up at the top of your TV. SOME TVs might let you adjust the settings to rid yourself of the scanline, but most consumer TVs will not let you without the maintenance code to protect your unit from over calibrating and braking your television. Hope this helps.

Red,green and blue lines across screen


I f these lines are slightly diagonal and they all showed up at the same time. you probaly have an open resistor in the ABL circuit. since your set is 13 yrs old, I would not put a penny into it.
You might take the front grill cover off and the panel behind it and find the little black box with 6 little controls 3 are for focus 3 are for screen turn the screen ones ever so slightly counter clock wise. the control in the middle is the green screen adjustment. If the green line goes away try the one labeled r for red and b for blue.

CRT lenses need to be aligned. Would recommend having a profesional technician do it. Easy fix for a CRT profesional but quite technical for the homeowner. Before fixing it, unplug. open up back go in and look at the front of the tubes with a bright flash light. If you see a brown square under the lenses you might just want to upgrade instead of fix. Brown square is CRT burn.
