Hi, I read this post after experiencing the same popping and LED blinking on my AKAI. I have removed the power supply and see the bulging caps. I would like to have you repair the power supply. Please reply to [email protected] with details on payment options and shipping info. Thank you, Jeff Horka

The led is blinking due to fault in power supply board.
On the power supply board there are some capacitors and ICs .if any of those gets short or faulty the power supply board will create problems and the red light will start blinking.
The components on the board needs to be checked with the help of multimeter and continuity tester.And the faulty components needs to be replaced with the help of soldering iron.
the procedure to check the power supply board is as follows:----
1) You are going to need a Phillips ( X ) Screwdriver for this procedure. The first thing you will want to do is find a suitable location to disassemble the TV. Try to find somewhere with plenty of space to work and preferably somewhere you will not have any hazards such as static (like carpet) Lay the TV Flat on its face (picture side down) and remove the 4 screws from the back of the TV holding the base on. Next you will want to process to remove the screws around the back cover. There are 12 screws you will need to remove (refer to picture for locations). Carefully remove the back panel of the TV. It may snag on the coaxial connector so be careful. 2) Once you have the back off of the TV you can see the Main board and power supply covers.You will now need to remove the left (right side from the back) speaker cover to allow access to two of the screws holding the Power Supply Cover in place. This is easy and pretty straight forward and has 8 screws around the perimeter. Once you have the speaker cover off you should be able to access the screws on the side and you will also want to remove the other screws from around the sides of the cover. Some TV's I have worked on only had 6 where others had 7 or 8. Just make sure to remove all of the screws before trying to remove the cover. Once you have the cover removed you will see the Power supply. Remove the wiring harnesses from the power supply board. You will have 4 cables at the top of the power supply and one main power input at the bottom. The main power input may have some glue securing it in place. Simply cut this with a knife or pull it loose. Once you have the cables off of the power supply you can remove it from the TV via the screws on the 4 corners. Be careful not to damage anything as you remove these screws. You now have the Power Supply removed from the TV.you can now get the power supply repaired from any local tv repair technician.or get new replacement power supply from the service center.or from online stores like :www.partstore.com or from www.shopjimmy.com Thanks. you can rate this solution and show your appreciation.
This series of TVs has a famous issue with the power board (part number MLT166A or similar). Several capacitors and zener diodes burn out causing some resistors to burn as well. If you are capable of doing component level repairs check capacitors on the board and zeners Z2, Z3, Z4, Z5 and resistors around them. If you prefer to spend hundred bucks and simply buy the working power board for it - ebay is your answer.
The power supply is defective if the TV fails to power up or the front light just blinks, common failure on these LCDs with MLT166A power supplies.

That is a bit expensive.
I would fix that module for you for about $110.00 with shipping and handling both ways.
The only thing you'll do is to remove the power supply module and send it in for repair.
There are about 16 to 17 capacitors that are a common fail point on this TV. I can repair your power supply board with new high quality capacitors and recondition the board to work like new for $100 + S/H, you simply have to send me the power supply module and turn around is approx 2 days from the time I receive the package to the time its out the door. Approx 8 business days according to the delivery carrier you use.
