If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

SOURCE: akai lct3201 power problem
I fixed my Akai LCT3201AD in about 30mins. using 3 small parts from
Radio Shack. Once I got the back off, I found the power supply board
(PSB), mine was part# MLT-169B rev1.2. I looked at the capacitors
(caps.) first, because they are usually easy to diagnose. I noticed the
caps. bubbled out on the top of the board (where all the cables connect
to it). There is 3 of them in a row, positioned between the two large
heatsinks. My guess is that the heatsinks are generating a LOT of heat
over time, because of bad ventilation, and causing the caps. to fail.
I went to Radio Shack and found 3 caps. (only had 3 in stock). The original ones were 16V-1000uF, Radio Shack only carried 35V and 50V in the 1000uF caps., so I bought the 35V ones and headed home, I removed the old caps. from the board, and installed the new ones. The 35V caps, are a little bigger, so its a tighter fit on the board, be careful. It took longer to remove the back from the TV than it did to do the soldering. YouTube.com has excellent videos on how to de-solder caps. on PSB's.
Total money spent on repairs:
$1.59 ea for 3 Caps. (part# 272-1032) $4.77
$2.99 for new soldering iron tip + $2.99
$1.00 donation for St. Jude's + $1.00
Total including tax $9.30
So for less than $10, I did a repair that my local TV repair shop wanted $575 for. Online stores want anywhere from $100-$275 for a PSB. If I get another 2 yrs out of it that's well worth $10.

Unplug power cord- safety first!
check powersupply- top center right is p.s.
top left side of powersupply you'll see 5 capacitor 3300uF 10V.
see any pop up on top? replace it All with same rate or 16v is O.K.
do not use temperature rate 75c. Use 105C.
if you know how to solder. you could save $300 at least! Mahalo!

It's common for capacitors on the power supply board to go bad (tops will swell up) and cause the same problem. these new LCD tv's are all very bad when it comes to power surges.
