There is a brilliant violet light in the back of my Samsung Television model # T X N 3234HF CRT .Along with it, there is a fan in the same area that no technician can figure out why a big noise is started every time I open this television.The technician bought already another violet light and adjust the fan but it still not working properly.Please tell me what to do because I am very tired of this problem. Again send me an answer soon is possible.Thank you!
