Re: SONY KDL-40XBR4 Tab bonding repair
I am thinking I have the same tab bonding problem with my Samsung. I wanted the problem to be an easy fix and have ordered a TCON, POWER SUPPLY BOARD, and the board with all the video inputs, but I doubt those are to blame after seeing many of the scenarios posted on various sites. Where is the best walk through on doing the TAB REPAIR ?

Re: SONY KDL-40XBR4 Tab bonding repair
I find your repair to be ok ,but i have also found this will not last as the material you used will eventually release the pressure on the tab
I have used much harder material eg silicon tubing or tape that does not loose the tension over time .anyway good luck in repairing these tvs
