MEGMEET MLT168K (AKAI)

Well, I'm finally on the boat with trhe rest of the Akai buyers whose Megmeet P/S's have failed them also. I noticed in one of your posts you stated that you ordered a P/S from Megmeet and that solved your problem. Where? How? Who? What did you do to order this? Any/All info you could provide me with would be greatly appreciated. I have an Akai flat panel which was powered by a Megmeet MLT168K REV:1.0 2006.11.28 power supply. Please e-mail me back ASAP at madison343@verizon.net.

SOURCE: pwer supply board repairs

this model uses 2 different boards--both are not available from Akai (SAMSUNG) look carefully at all the filter caps on the power board--many will be bulged up at the top---last one I did had 20 bad caps---space allowing--replace with higher voltage rated caps---8 were 2200 mfd @25 volt, 4 were 3300 @ 35 volt, 7, 1000 mfd @ 10 volt, and one 1000 @ 6.3 volt---- Sets with 10 digit serial number use one board and sets with 8 digit serial number use another board---I have seen "rebuilt boards" on several sites on the internet for about $115 + S&H---which is about what the original board replacement sold for when they were available.

I have an Akai 37 wide-screen LCD TV/DVD Player combo and it no longer turns on


Chances are it is the Power Supply. It is a Megmeet MLT386X which is hard to find. There are places that will repair the old one. You remove the covers running across the heat sinks and if the capacitors are bulging, the repairs are within the capability of anyone who knows how to use a soldering iron.
If you are handy with a soldering iron, LCDalternatives sells a kit with ALL electrolytic capacitors prone to fail for $15.95 plus shipping. I bought the kit and fixed mine. It took a couple of hours to unsolder and replace the capacitors.

Tramaine, I would suggest a new PSU. I have used ShopJimmy.com in the past with great success. Here is a link to the part you need on their site. Hope that helps! TeeVeeMan2

T.v. won't turn on


The following parts can be purchased at digikey.com or mouser.com web site. I am also posting all of the things I have found so far with these TVs.

Here are few possible solutions:

If you have no red light and you have a Megmeet MLT386 power supply, check these parts:

1) Swollen caps on the secondary circuit (may cause the red light blink problem, but also see below).
2) Blown fuse F1 (5A/250V) this is caused by a shorted FET at QA1 (20N60), you may also find that SMT cap CX23 is burned up (.001uf) which is in parallel with diode DA2 which may be damaged/shorted, replace these components.

If the power LED goes from red to green when powered up but no picture, then it might be lost +24VDC from the power supply:

3)Check fuse F2 (3.15A/250V, I put a 5A in), if it is blown, replace FET at QA2A (9N50C), replace QA2 as well (9N50C). Check SMT resistors at R233,R234,R235,R236 (.47 ohm). If open, replace with .1 ohm 1W or 2W resistor (easier to source). Also replace SMT transistor QF1 (2X4 or 2N4401 NPN transistor). And replace diodes at DS2 and DS1 (HER207), DS2 was shorted, DS1 was ok but I replaced it anyway.

I dont know as much about the Megmeet MLT169A, but it has similar problems and similar components.

4) I had to replace all of the capacitors in the secondary circuit (there are six in a 3x3 row marked EC9 (1000uf35V),EC10(1000uf35V),EC14(470uf35V) and EC18,EC19,EC20 (all 1000uf35V).
OK for the Megmeet MLT169A with red flashing LED when turned on I found that IC7 was bad. This is an SMT component on the solder side of the power supply. It is a 4407P (P channel 30V MOSFET). For testing purposes, we jumped across it to feed +5V to the TV permenently instead of allowing +5V to go into standby.

There are 2 1000uf/16v caps that blow on the board. The second one is under the heat sink nearest the one that is easily seen on the board. You might also have to replace the 220uf/25v caps under the heat sink as well.

The MLT169A is a version number issued by MegaMeet in asia who built the supply. The correct part number for the SMPS for that unit is: E7802-005008 and unfortunately they are no longer available... However, there is some good news, those supplies can usually be rebuilt but you need to have the equipment, knowledge to make the repair...

Red light still flashing


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
