LED Indications

The front panel Status LED provides an indication of

the set's operation and the possible cause of a malfunction.

If an abnormal condition is indicated, perform the

Self Diagnostics procedure.

Self Diagnostics

To activate, press the front panel <ACTIVITY> &<CH

??> buttons at the same time and hold for 5 seconds.

The STATUS LED will then flash denoting a two digit

code.

• The number of flashes indicates the value of the

MSD (tens digit) of the Error Code.

• The flashing then pauses for approximately 1/2

second.

• The LED then flashes indicating the value of the

(ones digit) of the Error Code.

• The Error Code is repeated a total of 5 times.

Example: If the Error Code is "23", the LED

will flash two times, pause, and then flash three

times.

Table 2-2: LED Indications

Error Codes, descriiptions and the most likely cause of

the error are listed in Table 2-3.

Note: The TV must be in "Shut Down." The LED

will probably be indicating an abnormal

condition. If the TV is switched Off, AC is

removed, or a System Reset is performed, the

code automatically resets to "12" No Error.

See the Error Code Log to retrieve a history of

errors.

Note: Use the front panel buttons, not the remote

control.

Note: If there is no response, the front panel may be

locked by a V-Chip setting. To unlock, press

and hold <ACTIVITY> on the front panel for

8 seconds.

LED Indication Condition

Off Off (standby)

Green Power On

Slow Blink Green Power Off with Timer Set

Fast Blink Green (80 seconds) > Off Power Off (Cooling fan still working, 80 sec)

LED Indication Condition

Red Lamp Failure

Yellow TV Too Hot

Slow Blink Red TV May Require Service

Slow Blink Yellow Lamp Door Open or No Lamp Installed

NORMAL INDICATIONS
ABNORMAL INDICATIONS (For details perform Self Diagnostics Procedure.)

Hi Andre,

May I know if the LED light at the front panel has a pattern of flashes or flashing continuously in green color.

Please check if you can access the "Self diagnostic screen" by following the steps below.
- To activate, press the front panel "Activity" and "Channel down" buttons at the same time and hold for 5 secs. The Status led will then flash a two digit code. Example, if the error code is "23" the led light flashes 2 times(blink, blink) pause and then flash 3 times(blink, blink, blink). Let me know the error code to narrow down, it will help to diagnose where the fault came from.
Note : the TV must be in shutdown not switched off, or AC power cord is removed because the code will reset to "12" means no error. Use the front panel buttons not on the remote control. If you can't access the self diagnostic, press and hold the "Activity" button on the front panel for 5 secs before entering the "self diagnostic" code.
Regards,

Common problems on Sharp LCD tvs as tv it is agings,tv Power LED and OPC LED,LEDS lights flashes happen to mine Sharp tv many times and i had it two years,do this many times,tries to turn on the tv.By trying pushes the power button the remote again if OPC LED and power LED,LEDS lights flashes together.Everytimes the OPC LED and power LED lights flashes,just push the power switch on the tv remote and wait for the tv main Tuner signal board to kick in the backlight to light up tv to work.Have to do this like three or four times before the power supply board to kick it in to make Tuner signal to work.If u require to this more than 5 or 6 times the main tv Tuner signal board it is shorting out and beyond trying to kick in by the power supply board.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish tv Tuner signal board for the replacement.

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 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 is the troubleshooting guide for your unit. Hope this helps.

TROUBLE SHOOTING GUIDE
TROUBLESHOOTING
Symptom Remedy
1. Remote does not turn on system
- Check and replace remote batteries if the display fades while
any button is activated or no display is present. - Point remote towards IR receiver during transmission. 2. System does not turn on, no green LED & no beep
- Check wiring. (see "installation instruction")
- Check modular cable to receiver.
- Check diagnostic LED status in the upper unit control box.
3. System does not turn on even when receiver green LED is on.
- Low or over voltage condition, check diagnostic LED status in the upper unit control box.

4. Fan runs but no cold air.
- Evaporator temperature sensor reaches low limit, defrost mode.
- Check diagnostic LED status in the upper unit control box.
5. System runs continuously in the cool mode
- Remote was set for "I feel" mode and is left in a heated environment (sun etc.)
6. System runs continuously in the heat mode
- Remote was set for "I feel" mode and is left in a cool environment

1. Diagnostic LED (green)
(Note: Located on the control board in the upper unit control box.)
a) The LED is on when the 12VDC is adequate and communications are
present.
b) The LED is flashing fast and steady when in the freeze mode. Evaporator has frozen and the freeze proctection switch is engaged.
c) The LED is flashing slow and steady when the delay on break timer is
activated.
d) The LED is flashing 1 cycle on and off for one second with high or low
12VDC. Check the incoming 12VDC power for OK.
e) The LED is flashing 2 cycles on and off for one second with a
communication problem. Problem with the control board in the unit and the remote.

Hope this helps.
