It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Hi Aaron,

I just want to ask you something before I give the solution, does the unit gone to start-up problem (needs warm-up before it finally turn on, needs to pressed the power button key several times, needs to unplug from the outlet and plug it back in)before, you have said that you've encountered it last few months?

If going through a cable box you may be loosing signal from time to time. Try playing a DVD to rule out the possibility that its your tv. Try replacing cable box, or add a cable amplifier. Hope this helps.

If the induction motor ain't going I would look for a blown 3 amp (purple) fuse on the control board. If that was good I would check if any of the roll out switches were tripped. If a rollout switch was tripped check or air restrictions somewhere.

Reimage the hard drive by opening the DVD drive door and inserting the recovery disk, which is obtainable from a distributor such as Betson in the US. Close the DVD drive door and power the game off then on again. Follow any on-screen instructions as the software installs. If this procedure fails or the game still gives trouble, you may have a failing hard drive. You could attempt replacement yourself if you feel up to it, or alternatively send the entire computer unit to a distributor or specialist dealer for testing and possible repair as necessary.

I had the same problem. Could you let me know how to replace the power supply? Thank you in advance.

you might want to have the thermal fuse checked... seems to be an issue... sony knows about it but doesn't want to share this info with many.

amazing how you can spend big bucks on a tv and the life of the tv isn't all that long.

My TV won't power on either with the remote or with the manual power on. I hear a clicking noise and it appears that the TV is turning on and off. After several times it stops. Never actually see a picture.
