Don't unplug every wire and turn it on...Those ribbon cables drive the Y main and Xmain boards. You can blow the Ymain if the ribbon cable is disconnected. Leave the ribbon cables connected, and look for a 1 second blinking light on the logic board. Pink picture ? Check the VS voltage on they Ymain...it should be close to 200 Volts Check the Panel's voltage sticker, the Vs should match the sticker.

You stated --

On the Ymain, there is also a VSC voltage created ON the Ymain board. If that voltage is low, or excessively high, you'll get a NOISY pink screen. That's the KEY. Do you get a pink picture, or Noisy Pink screen with no picture?

Xmain fuse. When i disconnect the board i have the same problem than at beginning. The screen is not clear and have snow the screen is like pink.
Expert:  TV Tech1 replied 1 year ago.

When the Xmain is dead, you can end up with a pink blob in the center of the TV screen. That's what I've seen. Since that specific fuse is blowing, I'd replace that board first.

There's 2 different boards used in your model. This site shows both with instructions on how to identify which board you have.

Compare your board with the information given and order that part.

You think that the another board is ok. In your experience?
Expert:  TV Tech1 replied 1 year ago.

If the TV has a lit screen, the Ysus and power supply boards should be good.
