Thank you, I repaired my Tv thanks your tutorial ! :D I bought a rework station and a spare TPS54334DDA 8-pins chip. I asked Texas Instrument (TI), there are only two kinds of TPS54334 chips : 8-pins and 10-pins. What you need here is the 8-pin. Replace your chip and Tv is good to go.
I moved this tv from 1 room to another and when starting it turns on like going to reboot and then turns off and fromt lef light flashes 3 times continuously Any advice? Thanks
@@SOSfixElectronics Hello, thanks for your answer, I only have + 24V on the chip fuse F404 3.15A. I have 0V on all resistors (gray). What do you think I have to replace the Chip Fuse F404? Is it broken? I think I'll change the F404 and the IC TPS54334? What do you mean ?
@@shqipstars7796 is the fuse tested open? If yes before you cha ge the fuse check for shorted component cuz the fuse usually blown if there is a short.
There is design problem by Sony and they fix it for free until 06/23 the chip may get short again, because some components needs to be adjusted in order it to work ok . Sony actually replacing the new board is without this IC

Update : same ship burnt again after 3 days. Another faulty component seems responsible.
check for short or partial short in the input and out put of the ship
very nice! Almost like playing a game - trying to follow where the problem exists. Thank you.
Wow. Thanks for a great explanation! I can't find that IC either. Do you know the model number for the whole board? TV out of warranty... :(
sorry i dont remember, take the back cover and check there for the board number
