If it's failing to turn on reliably, the main power supply is probably at fault and without some technical background and a couple of test instruments, you will not be able to do the repair yourself. 
What you can do though is; unplug the set, let it stand overnight or at least several hours, remove the back panel and look for a separate board with mostly larger components on it; it will have a ferrite core (no laminations as with a line-frequency part) transformer on it and several larger capacitors which are cylindrical and mounted vertically to the board.
 
Before touching anything inside, especially on that board, allow several hours to be safe since the larger capacitors can hold a painful voltage charge for some hours.  
 
If you see signs of overheating such as discoloration of the board material, it may not be repairable but if you can find a part number on the board, you might be able to buy the power supply and install it yourself but it will likely have the same problem eventually unless they have altered the design.
If there are no signs of heat damage to the board, there may be companies offering to repair it as a subassembly instead of repairing the whole set which could be much more expensive.
If you choose to replace or have it done, the power supply still may not be at fault since most are capable of switching on and off if a downstream problem is causing an overload.

Tv no picture Akai


I don't remember exactly which ones I replaced.Look at the capacitors on the power board,and replace any that have the top,or bottom bulged out.The capacitors didn't cost much,maybe around $10 with shipping,depending on how many you need.Do you have your power board out?I hope this helps.If you have any questions,please let me know.
Thank You very much!

Akai 4290 power board


Yes, I'm sure the board is bad. I had the TV checked out by a local TV repair shop. I also opened the thing up to see if I could do anything with it and it's obvious that this is the board that has bitten the dust. The correct number for the board is AA98-00188A. I made a typo in the first post.
