Communications have been lost between the video processor on the
FB1/FB3 board and the TCON (TFT Control) board which is part of the
LCD panel. This can be caused by a defective FB1/FB3 board, a defective
LVDS cable, or a TCON failure. On XBR models using the frame doubling
UB1 board the problem could reside there.
Edit: I was also able to put another LCD to see if it was the pannel and still no screen. Also when I shorted which ever pannel out, the screen whent black while the back light stayed on. Now after turning it off then back on the back light won't come on either.
My warrenty was voice. Because I opened the back panel.
What ever happened to your 46XBR4 till the end of 2012. Do not open your panel. Because your will be very upset and sorry. Their Technicians is very racism and unfriendly.
If anyone had fix the problem with 46XBR4 with it turned with solid green light, then 30 second later switch to standby red light and kept blink 5 times and continuously. Please help.
Am I correct in seeing that you voided your warranty? If not then you have an extended warranty that covers your panel until 10/31/2012. There is not a part# listed for the t-con board on this model. Sony never released those parts. However. for serial#'s from 8,000,001 to 8,200,000 the part# for the panel is 180249113. For serial#'s from 8,200,001 to 8,500,000 the part# for the panel is 180249131.
After I checked my Serial ##, and 82,4 range. So therefore the part would cost me $1700, and this is crazy. If anyone a good lawyer please refer me. I am will to spend around $300 to $500 to fight this case. and I want anyone this same LCD know not to make the same mistake that I did. I'll contact consumer affair and see if I can get some help on this.
The fuse is located just above and to the left of the main T-con cable input CN1 at the bottom of the board. It is the smallest of the SMDs on there and labeled F1 . C1, C2, & C3 are right there. It is to the right of C3
This happens all the time. I am a repair shop and have done probably 50 or more of these in our store. TV is JUNK . Sony should be ashamed of the panels and products they have started to produce. Of course American consumer society asked for cheap and now that's what we have gotten so .............
