You said that you could send a diagram of the capacitors you replaced. My tvs been having the same line problem. It seems from the other posters that it is the 10u, 100v electrolytic that's the problem and that by replacing it with a 10u, 250v it can prevent it from going bad in the future. I'm not sure what your thoughts on that are, but any help you can give would be great. I'm only working with a fairly basic knowledge of electronics. anyway thanks a lot

U talking about way back in the 40 and 50.From the 60 on tv all use intergrated circuit board.Mostly ICS chips now,no more tubes and analog parts.The problems ur tv have is the Horizontal IC chip is dead.
Circuit diagrams are available online from 5-20 dollars. I doubt it will do you much good, as you will need to be an expert at tv repair in order to read the diagram, and trace the problem. It sounds to me like a bad capacitor near the horizontal deflection circuits, or a resistor near the pincushion adjustment could have blown. If you really want to learn how to fix your tv, you should visit some learning websites that explain the different areas of a tv circuit board and their functions.
I recently had my phillips 27" model
27PT6341/07 repaired after warranty expired due to white lines
appearing at the top of the screen. The shop advised that it was a
capacitor giving me the problem. So, after getting it back, I examined
the repair job and the shop had replaced a capacitor at the back of the
main board, next to the rear rca inputs. It is labeled 10uf 100v. I was
told that it would fail again soon because it is a manufactures defect.
For me it is at location 2465. Here are a couple of photos of the part. http://farm4.static.flickr.com/3215/2337629026_eaa30cfa18.jpg?v=0
Ok the TV repair shop was correct the problem is with out a schematic you won't know which one it is. Let me explain. Even if you send a picture that actually tells a technician nother but the location of two capacitors. What is needed is a part number c13, c67... you get the point and then these can be looked up in a schematic to determine where they are in the circuit. I would suggest getting a schematic and sending an electronic copy to whomever you want to help you with this problem. I would be glad to help you but as a technician of 25 years I can only say that having and providing a schematic would be of a greater help then a picture. Unless yo plan on taking a picture of the whole circuit board and sending the model number and make of your TV to a technician so that they can look at the picture compare it to a schematic that they have (if they have one) and using that determine which capacitor or capcitors have to be replaced.
Hi, I have a Philips 29PT9009/12 TV. Recently I have begun to see horizontal green lines on my tv, when either watching a dvd or watch tv. This has gotten worse and now the green lines are more visible and the background is now turned a shaded green. Please help me. Thanks in advance
