I purchased and AKAI LCT2701TD about 2 years ago...it was working fine until today. I can no longer turn the set on and the indicator light in the front of the set is now flashing red. From what I've gathered it is and SMPS failure and a part can be purchase and easily replace for $70 plus shipping. I was wondering if you could help me with the name of the part to order and where it can be purchased. Thanks in advance!!

Re: AKAI LCT2701TD SMPS Failure: Red flashing light
I do not think there aren't any new power supplies available to fix these LCDs. The only way to make the LCD work again is to have someone to repair the power supply.
You could send me an email to email@example.com for more info.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Hi The flashing light is actually a code indicating an area that may be defective. With no light at all, I would assume something is wrong in the primary of the power supply or a major component has completely shorted thus causing the primary to stop working. Find a reputable repair person. Good luck
The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.

The failure of a blinking light is from a defective power supply. It could be a zener diode that is faulty, rectifier and a few capacitors as well.

Our AKAI also shut off & the red light started to blink...got no help from AKAI, but did from COSTCO. We bought the set before the 90 day warranty they have in place now, so they referred us to COSTCO Concierge Services: 1-866-861-0450. We were referred to a repair service & after discovering what the problem was found out that AKAI not longer has parts for this model. COSTCO replaced our TV---talk about satisfaction guaranteed.
I had the same problem; the blinking light problem is caused by a bad power supply. It try’s to power up but senses a failure so it shuts down and just keeps repeating this process. I troubleshot the problem and found that zener diode Z3 (27volt 1 watt) was shorted and zener resistor forgot designation (2 surface mount 10 ohm resistors in parallel) were open. The zener is under a heat sink so it is hard to see. Also there were 4 1000uf capacitors that were bulging so I changed them as well. I got the parts from digikey for 20 bucks and its now working fine. This was a lower cost TV at the time of purchase so it seem the manufacture used low quality parts and I would suggest trying to return the TV to Costco before fixing it. Good luck.
You just had to buy the cheap one... These units have an all too common failure in the SMPS, (made in China) which is a MLT166A part number if you're buying the whole supply. But the SMPS can easily be removed in this unit and after you access it you'll find three 16v/1000mf caps that have failed EC18, EC19 & EC20, together with Z3 a 27v 1w zener diode... You can replace the caps with a 25v/1000mf if you order them to size. The higher voltage will provide a greater reliability...
If any or all that sounds too confusing you can simply replace the entire SMPS for just about $70.00 plus shipping. They're available at Fox International 888-498-7278 but don't be surprised if their temporarily out of stock and on backorder. Techs buy these things by the case because they are that common a failure.
