Question about Magnavox 19MF330BF7 19 in LCD TV

Open Question

Magnovox 19" LCD tv sometimes won't turn on without unplugging the power cord and replugging it in.

I'm using my 19" Magnavox LCD tv as a second monitor. However, sometimes when I turn it on it just keeps a blank black screen and won't turn on. I have to unplug the power cord and plug it back in to get it to turn on and function properly. This doesn't happen every time, but probably about 50% of the time. I haven't been able to figure out what's causing it.

SOURCE: LCD Monitor Goes Black during Use

I had the problem sometimes, but then I connected a second computer to the analog input and found out, that the screen didnt turn black but switches between the inputs on an on.

I found out that the "input" button seems to be short or damaged, as the behaviour was invertable by pressing the button. I blew into the button some times (a very naive solution, yeah) but it worked, the switching stoppped.

SOURCE: westinghouse lcd monitor 19" - screen turns white

Fade to white might be caused by a bad or open connection to the backplane or bias voltage setting of the LCD. Check the connectors and cables between the LCD and the main board. Also, look for loose or disconnected ground wires.

TV will not turn on


Check the wall outlet, make sure there is power at the wall. If not, check the breaker panel. If there is power at the wall, check the TV for a manual on/off switch. If you have a power switch on the TV, turn it off, wait 10 seconds, then turn it on. If no power switch on the TV, unplug the TV for 10 seconds, then plug in again. Use the remote to turn the TV on. Check for a fuse or circuit breaker on the TV, usually near where the power cord enters the TV.
Make sure you have good batteries in the remote. If all this fails, then something may be damaged inside your TV, as a result of a power spike before the power went out, or when it came back on.
Take it to a repair shop.

I replaced an apparent blown fuse, TV still won't power on.


Most likely your power supply is damaged and will need to be replaced. Sometimes, power supply manufacturers add additional "fusible resistors" to provide additional protection.

Hi my son got a 19inch emerson tv for his 2nd birthday and now anytime it gets plugged in it flashes different colors and the buttons does't work and the only way to turn it off is to unplug it!! can this...


Press the the cursor key up followed by down and power the TV off with the remote or the TV itself. Please use the original remote for this. Unplug the TV for a few seconds...replug and power the TV on. The second thing to try...press the cursor key left followed by the right key. Power the the TV off with the remote or the TV itself. Unplug for a few seconds...replug and power up the TV. Some of these TVs left the factory in the service mode. The fix is pretty simple. Thanks asking and show a few hands of support!
