    I was watching the TV and it just shut off. The TV would not tunr back on. I unuplugged the TV and let it rest overnight. The next day it come back on. However, it turns off after an hour or so. We had this problem last fall. It did not occur over the winter, however it is happening again now.

This may be a power supply failure. The set would have to be troubleshooted to determine the exact cause, failed parts, and replace them. It is also possible that there is a short somewhere else that caused the power supply to shut down or be damaged.

While I was watching my Emerson TV I heard a loud click and the screen went black and audio went off. When I press tv button on cable remote the tv button glows red, and nothing happens on the tv.


Hi the power supply might have shut down through overheating turn the power of at the wall socket & wait for a short time before trying again the TV might reset itself if this doesn't work its probably shut down from a faulty component. good luck

My tv shut off while watching and won't come backon


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

You need to boost your signal somehow, get a better antenna. nothing is wrong with the TV, this is a typical Dropout when signal is low.

Still won't work


Hi again,

This forum has much info re Mitsubishi PTVs. Nonetheless, an excerpt from there....
1.Set the Layer Switch at the top of the Mitsubishi Remote to TV.

2.Press and hold the POWER button, and while holding the power button enter 090.

3.Now the remote should function like this:

Power = Power On Discreet
Stop = Power Off Discreet
Pause = AV Reset

Pressing INPUT followed by:
PIP = DTV
1 = Input 1
2 = Input 2
3 = Input 3
4 = Input 4
5 = DVD / Component 1
6 = Component 2
SQV = Input STB
QV = Input VGA
PIP CH Up = Antenna A
PIP CH Down = Antenna B

4.When done, press and hold the POWER button and enter code 000 to return to the standard remote functions

Power button Flashes


For the first one, please list the model number and count the blinks. Also, can you please post each problem separately. It will get too confusing trying to address 3 sets with different but similar problems.
Thanks,
