In standby mode, no obvious leaking caps.would a esr meter help me find a cap that is leaking with circuit powered up?

No... we got it to come back on and now we havent tuned it off since... we just leave it on 24 hours a day!

I have not worked on your particular model. But, I have serviced many TV sets over the years. My answer will ge generic.
Check all the capacitors in the horizontal output stage and power supply areas for high ESR. All the caps that are out of spec must be changed.
The high voltage multiplier & flyback can also cause the fault you are having.
You have to consider that the DC voltages are not the only important spec that has to be met. There are also many power drive signals that work with reactive devices. If there is any defect in the critical areas there will be failures.

I have the same set, and same problem.
After many hours/days of reading about this issue (which seems to be a popular one for this series and others) I have found a few sites that have detailed info on what can be done.
This link is for a different set but the same issue.

This problem seems rampant on many Sony sets. There really should be a class action suite against them for the replacement cost of the parts which can be $400(USD) or more unless you are handy with a soldering iron.
I have a service tech coming by to look at the set soon ($75) so he can tell me what is actuall wrong with it. Once I know if it is the D-board or the usual 3 ICs that die. I will most likely have a friend of mine solder on some sockets to replace the ICs if the happen to die again.
Good luck

You are correct. You are right about the power supply and replacing with led hdtv. You will be happy with a Samsung led. Time to upgrade.

Usually answered in minutes!
never use an ESR meter even the TV is in standby mode, unplugged and wait for at least 30 minutes
if your in a hurry, bleed the largest capacitor with a 4.7K 5W resistor and wait for at least 30 seconds.
