Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

SOURCE: LCD TV SCREEN PROBLEM RED HORIZONTAL LINES OF DOTS ALL OVER SCREEN PLEASE HELP

This should be repairable. It may be the LVDS Cable or the Main board problem. The only other problem is the T-Con Board.

SOURCE: Colours missing from tv

There are three color guns in a TV that make up the picture. Red, Green & Blue. It sounds like you have lost the green color gun.

You can get it rpeaired again, but your TV sounds like it is ready for TV heaven.

Hello Mr Kumar
According to you, there was colour displaying on your TV, and it has gone for now. It is now displaying picture in pure black/white also. Since black/white, picture is Ok, there is no problem to your picture tube. It now doesn't get chroma signals. That is the problem.
There are many reasons for this fault. The first one is related to Its RF stage, that is Video IF and Tuner stage. Since picture is correct in bl/wh, tuner has no problem. Your TV has PIP functions also. You just do this one first. Tune to a station with manual tuning, and advance the tuning process till the station goes out, and try to see, at any point during this process, you gets colour or not. If you get colour in this way, your TVs tuner has some problem. Before doing this keep the antenna corectly. If antenna is not in correct position this type of fault will occur. If these two won't help, the problem may be to its Chroma IC. If so this Ic should be replaced. You just do these things first and inform me about the progress through Fixya. I've its schematic diagram and can give you the number of Ics used in different stages. But I can do it only through Fixya. I can't send it to you diretly, since it is against our terms and conditions. Since the TV is a used one we don't know its present condition also.OK.

Sony wega 28 inch colours wrong, circle on screen


It sounds that there is some magnet near by TV that is affecting picture tube. Please remove any extra speaker or any thing that has strong magnet inside, unplug TV for 20-30 minutes, replug back in, turn it ON, hope that will solve your TV problem.
Thanks.
