Why my Mitsubishi tv won't stay on

Select the input channel for your Fire TV - Turn on your TV and select the input channel for the HDMI port you used to connect your Fire TV. You should then see a loading screen with the Amazon Fire TV logo 4.

Check your input source. TV is coming on and switching to an input where the source is not on

This is a prime case of bad capacitors in power supply. You may have only had it a year but how old are the parts that are in it?

Hello,

It's the problem of overheating in the power supply board of the TV.on the power supply board of the tv there are few capacitors and IC.any of this ic is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.

Hope this will helpout...

REPLACE THE LAMP IT IS LOCATED IN THE BACK OF THE TV THERE ARE INSTRUCTIONS IN THE OWNERS MANUAL FOR REPLACEMENT IT IS CONSIDERED CUSTOMER REPLACEABLE ITEM.
PART NUMBER 915B403001 Lamp (180W)

The flashing light red power light should only stay while the fan cool down for about 1 minute after a power off (remember to always wait before unplugging the TV so the lamp can cool down with the fan). Does that flashing start right away after plugging back the TV after an hour of letting it without AC power.

The red light should flash no longer than 10 sec. This prepare the light to be turned on. If all is OK the green should stay (no longer flashing) and the sound and picture come on.

As for the lamp flashing, i bet it's only 1 time each 5 sec? Or do it group many rapid flash each 5 sec?

Things that can be wrong:
-the fan lamp

-the lamp is not proprely inserted (wait an hour before manipulating it to be sure it cooled down, and use glove to not put body oil on it).

-Lamps is defective and is not operating properly so you can't get to the usual on screen message that recommend to change the lamp.

the plug the connects underneath is not connecting right you have to get at the plug and seat it correctly

David,
Let's start with unplugging the set from the wall power for 15 minutes. This will hard reset the micro... While that's unplugged inspect the buttons on the front panel of the Tv to see that none are stuck in a pushed-in condition. Plug the unit back in, power it up and if all works okay you're back in business... If not, let try a keyboard unlock. Press and hold the "menu" button on the front panel for 10 seconds. You won't see any on-screen changes but then try to select an input from the buttons on the front of the Tv.
After you've done these drop me a note and if we haven't solved it will try some other things..
