I do agree with the tech but if the green led don't come on and the 7-blink error code is still there. check the connector from the logic board that will be the board under the small signal baord. The small signal board have the AV input on it. Check the connector from the logic board to the power supply there should be one connectore btween those 2 boards. On the power supply side second pin from the left it will say Vs_On if the set has 0 volts the proble is the SSB or the logic board. how to determain that is to Use 2 Jumpers to short J8003 & J8004 on the left edge of the PSU (see figure below).
Use 1 Jumper to short CN2012 on the lower left part of the Logic PCB (this will supply a 100% White signal to the Display).
Plug in the AC to the PSU thru CN8001.
If PDP panel operates with White field screen then problem may be the SSB.

hello, amigo if the all the caps are godd then you have to replace the power supply board. don't try to fix it this is not an easy task. you are looking at almost $200.00 with tax an shipping. just go to google and type your tv model # and ask for the power supply board or just look for the part# on the board itself. good luck

The most likely problem are two failed capacitors on the main board in the center of the TV The failed parts are easy to identify as the top of the cap will no longer be flat but will have bulged up. DO NOT attempt to remove the back of the TV unless you know what you are doing.
soldering on a circuit board will be required to fix this problem.

Commonly it's going to be a power supply related problem. The two boards that need to be looked at is the Main Power Supply Board or the power supply board for the screen. The one that powers the screen, some manufactures call it a Backlight Inverter Board.
If you have some electronic experience, you can sometimes find a Service Manual for the TV over the internet for less than $20. It will have the all resource material for repairing your TV model. It's just the matter of replacing the bad part on the circuit board.

SOURCE: 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.

Check its back-light inverter board. Replace it. This is a back-light problem, especially if it is an LED LCD TV. If you wish to get some details, check the site linked here.Pull up older posts.

Sounds like you either have a defective LCD panel, LCD panel tab connection, or a LCD to T-con faulty connection. Does tapping or squeezing the left side of the TV change anything?

My tv comes on, but the left side is black & after about 20 mins. the whole screen goes black. you can still hear it, but just dont have a picture. it a philips 47 in. 7422D-37


Unplug the television, wait for 60 seconds.Then re-insert plug into the
mains socket and turn on the television again.

Your TV has a protective mode in case there is too much heat build-up.
Verify the clearance around the vents of the device to be certain there
are no blocking walls or cabinets which would limit the air flow.
If all above are OK, check the back light inverter board. For more details, visit this site 'Electro-help". It is an electronics equipments service help site. Google for it.

  • Your TV has a protective mode in case there is too much heat build-up.
  • Check the clearance around the vents of the device to be certain there are no blocking walls or cabinetswhich would limit the air flow.
  • • Check that the TV’s AC power cord is plugged into the mains socket.
    • Unplug the television, wait for 60 seconds.

If that fails take it back.. Good luck

I have a Philips 50" Flat HDTV model 50PF9431D/37. Problem with screen turning on. I get sound. I get 9 quick flashes in red. Then after unplugging and plugging back in several times. It then blinks...


I have the exact same problem! I have it hooked up to a power strip now to unplug it by flicking of the power strip and waiting for the red light to go out then I turn it back on while Channeling up 10 X's and then down and up until it comes on. I listen to the sound of the switch which it comes on. I turn it off if it is faint and then back on and channel up. Crazy process but it's been working. It takes about 10 minutes everytime to get the TV on until I get a tech to come out and look at it. The capacitor keeps a charge which is why the light is flashing with a code for 60 seconds./JJ

I have a Philips Plasma tv 42pf5321d/37 with sound but no picture


Thats the great sound of Exploding capacitors on either the power supply board. or another one in there. Now the set is in fault protection. It tried to warn you with the RED blinking LED that there was something amiss by shutting itself down. When you unplugged you reset the error and allowed it to do it again.

Best Regards and Smper Fi
