I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions

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.
