Question about Flat Panel Televisions

1 Answer

Power wont stay on, switches automatically off.

I have a KTV flat screen HD TV (model # LTW42DV). When I turn on the power switch it lights up green for a split second then turns off. Yesterday it did the same thing but worked after five times of turning it on then off. Today it wont stay on at all, there is no picture but in the split second it does turn on, you can hear audio from the tv.

Do you think the TV has died, and if not, how can I ifx it???

Thanks a million!!!!!

Green light stays on when trying to turn off tv. picture go's off when cable remote is used but green light stays onand you can see that screen is still on?


You need to set up the cable box remote for your TV , now you are just turning off the cable box. Some cable boxes have a switched plug on the back that will turn on and off with the box. If yours has the switched receptacle you can use that to turn the TV on and off by plugging your TV into the switched receptacle. Make sure the TV power is on, the receptacle will kill the power so the clock on the TV wont work. Otherwise you need to set the code for your TVs remote and use the system power button.

The tv will turn on but no the screen wont. and


Replace the lamp would be the first thing to try. Lamp door switch on this model is notorious for going bad. If you replace lamp and still won't turn on jumper door switch. If you take off back you can see switch board.

Stays in standbye and will only flash green (power on) twice before staying in standbye


The 6 inverter transformers on the bottom of the picture is the problem and what need to be tested.
Unplug the 6 wires that goes to the LCD screen. Use a multimeter to test for resistance from each output plug on the board. The one without the resistance is the bad one.
If this doesn't locate the bad one this way, Each plug should give out DC voltage if working properly. Test each plug for voltage.
The TV will automatically turn off in a couple of seconds like before. You'll have to keep pushing the power button to test each output plug for voltage.

Soon as you find the bad Inverter Transformer, just solder in a new one and the TV should work fine after that.
The part # for the Inverter Transformer is LTZ2PC0MS008.
Here's two places to get them:

Green Power Light


My TV does this if I do not switch the remote to TV instead of Cable. I am using HD DVR and have to switch back and forth from Cable to TV. Hope it works.
