Question about Haier L42B1180 - 42 1080p LCD HDTV

Open Question

Screen goes black and audio cuts out as if it powered off. But the green power light is still on and does not go off even after unplugging it and plugging it back in. Is this the Main Board?

I tried the flash light at an angle to see if it was the back light or back light inverter going out but I could see no image on the screen, Sufficient power is being supplied to the rest of the components.

SOURCE: Set cuts off

hi there,

Looking at your description, i would suggest keeping that TV turned off, it could be Potentially dangerous, sounds like there are some electronics inside the TV's main power input that are faulty and causing shorts in the internal circuitry which is what is causing the overheating, the overheating is due to the electrical currents and the damage to the board.

i would suggest calling Haier Tech support and attempting to solve the problem over the phone with either a repair/replacement.

if that fails, i would definately suggest getting the TV repaired some how, having unsafe electrics in the house is dangerous, take care !

Your problem is in the power supply. Some of the filter capacitor might be blown up. Try to replace all blown up capacitors or buy new power supply.

I switch on my PC, ensuring that all cables, leads and power supplies are connected properly. The tower powers up no problems at all. I switch the screen on, the green led lights up, the screen is completely black. A blue box appears centrally on the screen with the text 'power saving mode'. The green led light turns amber and then the screen just goes black.

Please don't suggest going to control panel, as I can't get that far.

My hp pavilion a430n is not turning on. even though i pressed the power button the light wont even turn on. it is truly annoying and the screen says something about the power supply and green, red, blue...


I suggest to open your computer and unplug your power supply and look for the color green and black cord which plugged from your motherboard. Then find a piece of wire and short the color green and black wire to test if your power supply is working and plug to your power socket. And check your electronic parts (capacitor) near at your processor, it might your capacitor blown out.
