The AKAI LCT3201AD I got from a friend who didn't know it was stuck in stand by. Took it to the local TV repair guy who charged me $25 deposit to check it out and replaced the power supply for $99 total. Works good except for DVD player that won't eject. Just need to figure out what bolts are to be used for mounting to the wall.
you have a power supply problem there are caps in the power supply that fail the will be bulged on the top these have to be replaced in most cases or a fast switching diode
or get a replacment power supply and exchange it
Normally the end model numbers signify a revision. Your LCD screen should work fine in the other one. Manufacture's tend to keep LCD screens within the same vendors for specific models for cheap replacements =)
If you are electronically inclined, replace the three 1000uf 16v electrolytic capacitors in the power supply board located above the power switch. They are likely bulging out at the top and failed. They are the three in a row at the top - center of the board, located between the two black heat sinks. Make sure you get caps rated for 105c degrees! I recommend replacing them with 1000uf 25v caps. 35v caps will work but might be a tight fit as they are larger diameter.
Should cost you about $8 for the parts shipped. You can get them from partsexpress or digikey or any good local electronics store. Your local radio shack may have them but they won'y be 105c and thus may not last long.
Not handy, ask around, there is usually some electronic tweaker guy around that will install them for a few bucks.
This has solved the turns on / then off problem every time in the 3 I've done.
The power supply is defective and will need to be replace or repair since no new boards are being manufactured.
I repair these power supplies, write to email@example.com if you require further information or assistance.
A very common problem with that unit is the power supply. You could probably open the rear case yourself and locate the power supply module. Look for the electrolytic caps EC18, 19, 20 all are 1000uf/16v Then EC9, 10 which is 1000uf/35v and EC14, 25 both 470uf/35v Replace these and you should resolve the problem. If you have some basic soldering experience and be patient it's not a difficult repair. Just make sure that you get the new cap placed in the same manner, they are polorized, having a positive and negative side.
You'll need some solder, desoldering braid and a GOOD soldering station or stick. Most of this, including the caps you can get at ACME sales in Florida.
I will say that the part that you bought could have been removed from another LCD and it might not be working properly due to components that become defective when they overheat.
It looks like there are not service parts or they are difficult to find.
Most power supplies I've repaired have components that failed after about 1500 hours of use.
The only way to get the LCD working is to repair the power supply to the component level instead of swapping it.
In about 95% of the time the power board is defective.
Let me know if you need further assistance.
I have just repaired one of these sets for the 2nd time. The problem is definitely the Capacitors on the Main Power Supply Board. If you are handy, you could replace them yourself, or You can send your board to me and I will make the repair for you. Akai initially used what I feel are sub-standard Capacitors on these boards, and I have found that by replacing most of them, this problem can be eliminated.

I had a power supply issue with my TV too. I was able to repair it. But, during my research I cam across a store which does sale the power supply.
