    You are right, I would have some-one do this. I do not have that skill or training. Just wanted to be sure that this repair would not break the bank. I'm just south of Boston, any ideas? Remember ,I lost picture, then power light and audio were pulsing off

That sounds like a backlight inverter malfunction. There is a cable that goes from the power supply board to the backlight inverter board. Your first objective would be to check if that is loose. The question is whether you want to do it yourself?

    Its not expensive at all. Even if the backlight inverter has to be replaced(part costs about 75$). Can you get me your zipcode so that I can look up our repair directory?

Magnavox 37MF23ID, would not turn on. Power button only blinks (green light). We have switched power cords and nothing happens. No picture, no sound.

if the power light comes on but the screen stays black, then your TV might be on the wrong input Channel. for example: you switch inputs when you play games or watch dvds vs. watching regular tv. Try to change the input

I have a Philips 347H E10839tv. I requested a channel that was not authorized on UVerse. when I tried to go back with the remote the screen went dark. now the set will come on and you can hear a sound...

Sounds like a problem with your power supply board or your cord or the outlet. Unplug the set from the wall for 1 minute and plug it back in to see if that works for you.

I have a sony KDL 46xBR2 when I turn on powers up green light stays on but a dark gray screen no picture or sound

The green light merely indicates that power is getting to your TV. The symptoms you describe point to internal power supply failure

1994 Plymouth Acclaim 2.5, 4 cyl won't start

on the backside of the alternator there should be a large black/grey wire. check to see if there is battery voltage on that wire. If there is not than you have a blown fusible link that is inbetween that wire and the battery. If there is power there than check for power on the dark green with dark blue wire. There should be power anytime the engine is running. If there is no power than there is a problem with that wire in between the alternator and the ASD relay.

Check those two out and let me know what you find.

Screen went dark (almost completely)

check your power cord and make sure it's plugged in all the way, and if it is, check your brightness setting.

Usually it's the Fn key + an arrow key. Make sure the brightness is up all the way
