i am having trouble with the picture on my tv. I recently replaced the lamp on it, then shortly after that it began to act up on me. Started to get what looked like a water color effect on the picture. It looked like it had issues with the shading of the colors. Now 1-2 inch thick horizontal black lines are starting to appear and fill in along the bottom, top and now the middle of the screen. There is also a vertical one forming on the left side of the screen about four inch thick. What part is causing this? This is the 2nd time ive tried to ask you, hope you respond this time to it.
