    my tv turn on to the red light only, but won't go to the green light

    How many times does the POWER led flash? Dont worry about the other lights.

    1x (constant blinking) = lamps or inverters
    2x = power supply
    3x = Main unit.

I had a problem with my Sharp LC-15e1u where it will not turn on
by pressing the LARGE RED pb on top. The power button remains red. It also used to be green. Well I tinkered with it and
found by starting with the power OFF,
Press both Menu & TV/Video
Turn on by pressing the Big Red Button
The power lignt is red for one second then turns green.
The TV Then turns on leaving you on channel 58.
The volume control slides from 0-30-60 and back to 0.
Also there is a small "K" in the upper left corner of the screen.

I'm returning the unit for a Factory warrenty. I bought it on
clearance "AS IS".

I hope this helps...

Assuming the inverters are bad, its better to replace all of them at the same time (there are 4 of them). Inverter A and B are the main inverters (generally $100ish is the cost... however it also depends if the service center decides to mark up the price). Inverters C and D are $10ish each (again, depending on markup). And generally, service centers charge around $200ish for labor. So total, youre looking at roughly $400-500ish.

Again, assuming the inverters are bad, they are available for repair. However, if the problem lies with the lamps, then you are looking at needing a new LCD panel (which are VERY expensive and cost more than the TV is worth).

This kind of problem is tricky to diagnose though. Basically all you can do is try to replace the inverters, and if that doesn't help, then its the lamps.

My panasonic th-42pwd8uk tv wont power on. When I press power it clicks to turn on then clicks again and the screen never shows up. No red lights no blinking lights just a solid green light.

Check the capacitors and replace the power components. It is an easy fix if handy with soldering electronics. Tv Repairman may charge less than $100.00 bucks to fix it !
Good luck

Turning on tv on a morning is a night mare led is on red press remote light goes off for about 20 mins then comes back on try turning on again goes to green light for 20 seconds then turns off again this...

usually is an issue with the power supply or power inverter for the tv. basically one of the capacators is not holding a charge like it should and is causing the power to drop. contact a repair technition or begin looking for a new tv.

My 42 inch LG LCD wont turn on, it worked fine in the morning. I got home tried to turn it on and it blinks green and then stays green like its on, but the screen is still black and I cant see or hear...

There are too many possibilities to know what's wrong with the set. About the only thing you could try is to unplug the power chord of the TV, plug it back in and see if that makes a difference, if not unplug again and leave for at least five hours then try again. If neither of those work you will need to get it serviced.

Tv wont turn on worked fine last night

If there is no power at all, then the problem is likely the power supply unit.
The PSU must be tested, then eventually replaced.

Power problems

Most likely the power supply. The part number is 270530 and cost around $130. You would need a volt meter to test.
