T NOWV WONT WORK

Hi!


Check your power amp circuit. Or, check if it is feed by the power supply circuit. Good luck,

If it's a led tv and if you have sound and, also, if you can see the picture with a flashlight very near on the screen in the dark, that means your backlight or your inverter circuit that control the backlight are defect. Good luck,


Serge.

Hi!,

I would replace the main board but check the power board before to see if it is ok. Good luck,


Serge.

Main board problem. Good luck,



Serge.

Tap on the screen with your finger end not to hard when the T.V. is on. If you see a white light flash, it means that the neon work, the backlight. So you should check your main board or your t-con board or a trouble in the power supply. Ask a technicien near you to check it. I would but i live to far. Best of Luck. Serge Lavallee.

some large surges can cause damage to multiple boards. What PC board did you replace? What you are describing sounds like a faulty main board

Definitely odd for sound to come through and not sound, especially via an HDMI connection.

I would contact LG for support, your TV could be defective.

Good luck

i want to know who wants to sell me their rca t.v?

solution

ok First question does the led continue to blink after 70 seconds after u plug it in. it is common for a cuircit board called the dm(digital module) to go bad in these units. this set has a keyboard lockout feature. Press menu for 10 seconds on front panel. if that does not release control then u more than likely have a problem with dm module. there are several bullitens about this and several things a tech can do to repair this set
