Facing TV Problems? Ask a TV Technician.
Hello [Sir/Ms], My name is Rick and Thank you for posting your question on Just Answer! I will be happy to help you with this problem,
I see you have 0 accepts on three answers,, what were your options,,,i dont want to waist our time with the same info
I need a technical answer, not a saler answer.
Do not tell me to go bring it to a repair center. I want to repair myself. Which sub-board is defective? Do You have case like this one?
I do not want to waste your time if you have no real solution.
I received an expertise from a tech of FixYa.com.
I found my problem, it's the Scaler board.
Hello, I have other comments and I bought the service manual.I watched when it becomes hot, regardless of video input, I see noise on the screen (video garbage) as a TV channel with no signal but the menu on the screen is always clear and stable.I removed the tuner board, Analog Digital Qam board, AV board.I have only the power supply, T-con and Scaler board, the problem still exists.I warmed the Scaler board, I have a lot more noise on the screen. When I cooled the chip IV200 (Pixel Works PW2300-30L), the noise disappears, the screen goes black but the menu is there.I do not know the function of this chip. I checked all the sub-supply (regulator) on the Scaler board, not easy, they're all good.I looked on the T-con board, nothing damaged (no schematic for That board).
