    Same problem here all 4 components replaced but still have the same problem. Can someone offer anymore suggestions. Checked all the diodes and Transistors that I could measure and all seem to be fine. It makes it really hard to troubleshoot with so little info.

You also have to replace the 2 resistor on bottom of the board they are 10 ohms each they are surface mount 1/4 quarter watt each they are next to z3, also have to replace the 3 caps. I have fixed 4 units with the same problem this must be obviously a design issue since many of these tvs have the same problem.
hope this helps

The original request was with regards to the LCT2701TD TV, which I believe uses the MLT166A power supply. While similar to the MLT169c, from the pictures I've seen, it has different input and output connectors and would not be a direct replacement for the MLT166A, as it might be for the MLT168a/b.

Exactly the MTL169c is a direct replacement for the MLT168a/b etc... that was used in these akai lcd panels. If you replaced the three problematic caps and it's still not working got to megmeet.com and order the MLT169c :( it cost more than caps but a lot less than a new tv

You need to order the MLT169c from megmeet :(

LCT2701TD t.v. will not turn on. There is only a flashing red light.


Most failures on this LCD are due to defective capacitors in the power supply board.
The defective capacitors are 1000uF/16v, the reference designators are EC18, EC19 & EC20 and since the light is flashing. Z3 a 27v 1w zener diode might be shorted and two 10 ohms surface mount resistors might also be defective.
If you are fixing it yourself, you can use 1000uF/25v or 35v as long they fit in the space provided by design. Radio shack should carry the capacitors and possibly the zener diode but not the 10 ohms surface mount resistors.
Let me know if you need further assistance.

If Z3 was shorted, there are 2 surface mount resistors that were damaged when Z3 became shorted and they have to be replace as well. The reference designator for the resistors is R65A and R65B, their value is 10 ohms and 1206 is the body size of the resistors.
If you need further assistance or to get the power supply repair, write to jah2mil@hotmail.com

Flashing RED Light


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.

deebo24,
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.

Your pwer supply module has problem. Check diode (Z3) and 2 surface mount resistors (R65A and R65B).
Good luck
