LG 42PC3D has the same panel and sustain boards, same core issues and same troubleshooting process as the one described above.

it is not the same TV, mind you, it is just close enough to be able to use the troubleshooting explained above.

Once you do here are some service options:

Note this does not include main board, for example, but what it covers is the most commonly failing boards in your TV.

Hope this helps!

For this model it is usually power supply(look for popped or bulged capacitors) or YSus board(look for shorted components}

SOURCE: TV will not turn on

Ok, you stated that you get a green for a second and then a couple of blinks and then, it turns off. This rules out the power board but, its main control partner is experiencing some trauma. Normally in the plasma TV set, the green is a go but, if the PCB(Power control board), doesn't agree, the the power board will shutdown the entire unit after giving a few blinks. Its very important to remember that, the power board and the power control board are two separate circuit boards. In your case, the PCB is down and it will need to be replaced.

Please rate and god bless.

SOURCE: stalling coming on

LG's are known for having bad capacitors in the power supply. These components will cause all kinds of problems like not turning on, no backlight or no video and are known to do this after the TV has been off for a few hours or days. You will need service on this TV.

SOURCE: Blinking power light

The TV has developed a fault where the start up procedure cannot be carried out & therefore the TV switches itself back off. You would need to remove the back of the TV & check if there are voltages going to your backlights (24v), are there all the other voltage rails present at start up eg 15v, 5v etc. Check the power supply to see if any of the capacitors are showing signs of stress such as a bulging on the top. If you do not have a multi meter to check voltages or feel comfortable to do this, then it would be best to contact a repair service centre.

...OK to begin troubleshooting this. Unplug the set and leave for 1 min then plug up and leave for 2 min push the power button and let light blink for 2 min.... now push and hold at the same time the MENU and DEVICE buton st the same time. this is the self diagnoses feature ... the lights should link then pause then blink again... this 2 digit code will help narrow it down. Also have you check the lamp yet?

No Picture or sound


The lamp cover door was not secured tightly. Door does not "push" shut easily. Got a little rough with it and latched it shut, then the tv worked fine.

TH-42PX60U red light blinks 10 times wont come on


On a Panasonic TV the 10-blink error code can sometimes be caused by low voltage running through an HDMI cable, particularly from a Media PC or some video game consoles. Try disconnecting any HDMI cables and unplugging the Television for 30 seconds, then power it on without the cables attached.

If this works, connect the cables to the front panel (usually HDMI-3) which uses a different controller board.

Power light blinking 2 times


2 blinks means the unit is having problem with 12 volt supply.
while power on you can check 12DC on power supply before shutdown.if the voltage is constant before shut down I would recommend to replace D board.

Panasonic pt-52lxc66 power light blinks


There are actually two red leds present on your tv and depending on which one is flashing is going to tell you what to replace. 3X on the Temp led will point to a faulty thermistor and you would want to replace this part. If the 3 red blinks are the lamp light than this is a error on the iris position and you would need to have the optical block replaced.
