My 32LG70 won't turn on and the screen remains blank.

My 32LG70 won't turn on. Plug it in and the red light comes on, but it doesn't actually get a picture. It tries, and you can hear a faint click each time it tries, but then the blue light comes on but the screen remains black after about 4 attempts by the tv to turn on.

Try resoldering everything back onto the power board.They become brittle sometimes.

That doesn't do it then buy a cheap cap meter off ebay for around a tenner and firstly pull off every single electrolytic then ceramic capacitor and test.

Very easy to test,look on YouTube for videos.

Replace faulty&marginal caps and your problem should be gone.Remember m8,take your time,don't rush these things.

    I have exactly the same problem. The power supply voltages are correct and the main board powers up and the chips get warm. It does the four attempts and gives up like the askers. Any result on this one?

Motorola cellular w376g, battery won't charge


If possible test with another charger like a car charger if you have one
also try removing the battery plug in the charger and put the battery back in (don't touch the contacts/gold pins)


if it works with other chargers then the charger is bad


if it doesn't work with other chargers charging port/battery/phone is bad

The red alert light indicates that the filter needs to be cleaned. I have cleaned it but the light remains on. I have turned the unit of and on again but it doesn't change the light. The unit is...


Tunr the unit OFF & unplug it for 15 minutes. Then plug it back in and turn it on. The electronics should have reset and reverted back to the original factory settings & the red light should no longer illuminate, as long as the filter was reinstalled properly.

Hope this helped you and thanks for choosing FixYa.

When I turn on my set, light turns green, then after 30 seconds turns red won't come on


Sounds like there is a problem with the power supply. Try unplugging the T.V. and hold the power button for 30 seconds. Plug the T.V. back in and see if that helps. If it doesn't try switching to another outlet, and if that doesn't work then you may need to replace the power supply which would probably cost anywhere from 140 to 200 for one.
