Hello i need schematic diagram for power supply Model MEGMEET - ML686 . that power supply used for LCD TV .it's bad Brand and nobody care in service center. hope somebody help


If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Check the present power supply [SMPS]; and find out the number of switching regulator IC used. Surf the site with that IC number. You will get similar circuit for SMPS there.

Element tv has to be turned on and off repeatedly before coming on


Either the on/off switch is defective or a broken lead to the switch. Take it to a repair shop.

Tv shuts off when you turn it on again it will play a minute


I think this might be bad/swollen capacitors in your power supply, or something odd in the +5VDC circuits of the power supply, but I am 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 PS secondary circuit (may cause the red light blink or shutdown problems).
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 we 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.

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
