How to fix a tv with constant blinking green and orange lights:
If your TV has been constantly blinking green and orange lights, it is likely that there is a problem with the power supply. The first thing you need to do is to check the power cord and make sure that it is properly plugged into the outlet.
If the power cord is not the problem, then you need to check the fuse box and make sure that the fuse is not blown. If the fuse is not the problem, then you need to check the power supply itself.
If the power supply is the problem, then you will need to replace it.
How to fix tv with tv doesn't come on when plugged in:
If your TV doesn't come on when plugged in, the first thing you need to do is to check the power cord and make sure that it is properly plugged into the outlet.
If the power cord is not the problem, then you need to check the fuse box and make sure that the fuse is not blown. If the fuse is not the problem, then you need to check the power supply itself. If the power supply is the problem, then you will need to replace it.
It might not be the fuse,it must be its power cord or the plug you are using try that if it works on other plugs and if not, check the power cord(cable).
Hello. If you have multimeter available you can actually check if voltage present at the end of your power cord first. If it's OK than you have to remove back cover from your TV and locate power supply board. It's very easy - it should be next to the power cord receptacle. First look for capacitors that have bulged tops instead of flat ones. If you locate any - replace them and check if it's going to take care of problem. Right next to receptacle connection is fuse located and you have to check if it's open. Replace it if needed. If new fuse got blown right away - you have short in power supply board. If fuse is OK - connect power cord and using multimeter try to figure out if 5V is supplied from Power supply board to the main board (the one that have all inputs attached to it). If 5V is present but power LED in front of the TV is still dead - you could have problem with main board. Best regards. Russ.
check outlet power by connect other device, check power cord if OK check then unplug tv and open the back cover and check power filter fuse power filter is the one that you hooked power cord if OK check power supply board fuses if OK check the power supply board for bad blown components .good luck
Just try to hold the power button while pressing for 15 seconds .If still not powering up then that is the time to check the fuse maybe the fuse is busted already,this is the common problem when you already secure all the corde and wall socket for electricity is there still your tv is not turn on.
there is usually about 3 fuses in mitsubishis many models have more than 3. Look the bord over good where the power enters especially in the center of the board.
