Dynex 55 tv turns itself off

It turns itself off. I have to unplug the cord from the back and plug it back in to get it to turn on. When it comes on the red light goes out and the blue light does not come on. It use to. It will only stay on for a 1/2 hour at a time after it turns itself off.

SOURCE: power button is green - no blinks / no picture / no sound

Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.

SOURCE: My dynex tv will not come on seems to be stuck in standby mode.

It sounds like the main power supply is trying to startup but failed because there is short circuits or the main power supply is bad. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

SOURCE: dynex tv no picture screen comes on and then goes black

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. Look for 5vdc, 12vdc, and 24dvc.

Console will not turn on. light is neither red or


Since you said the light isnt red or green im assuming its not glowing at all, and in that case you most likely over worked your adapter like i did. All you need to do is unplug the cord thats connected to a gray box from your Wii, and follow the cord out the other side and unplug it from the wall. The gray box is the adapter and if you leave it unplugged for a couple hours then hook it back up to the wii, the light should come back on, although in my case the light is now yellow when its off instead of red.

Tower problems


You may need to replace the cmos battery, its a cr2032 3v button cell
Make sure all your expansion cards and memory are reseated.
Make sure all cables are reseated.
your power supply could be bad

If that doesn't work try this


Here is my fix for the dell dimension 4400 amber light problem. It works!
replace cmos battery.
then unplug power cord form wall about 5-10 secs.
then plug it back in, wait 5 secs.
If amber light comes on, press and hold power button until it goes out.

(with light out, press and hold power button while amber light comes on and goes off again holding power button 2-3 secs after light goes out.) repeat whats in parenthesis until computer turns on
it should only take about 6, 7 tries.

After the computer boots, you may want to setup cmos or boot into windows.
After you shutdown, unplug power cord for 5-10 secs then plug it back in.
Press and hold the power button, computer should come on.
I found that's the only way to turn on the computer.
If you shutdown and don't unplug power cord the computer may not boot, mine didn't.
Strange I'd say
