Yesterday we had a power outage. When the power came back on, my TV would not work. The green light on the front just keeps flashing quickly. I tried unplugging it, and I unhooked all devices from it as well. It still won't work. Any suggestions? I own the Mitsubishi 1080 HDTV model WS 55511.

Likely has bad 1000UF capacitors on DM module. this will prevent rebooting.

power supply issue

Thats caused by weak DM capacitors when power is lost even for a minute the caps drain and then cannot charge again when power is restored so the led will blink non stop. The Repair kit called the WS48511 - WS65511 DM repair kit should solve the issue. The kit contains the caps and the cd with repair instructions. The kits available from www.tvrepairworld.com

Hello
make a System Reset process. To do this;
If the TV will not respond to either the remote control or the front panel controls and/or will not power Off, press the SYSTEM RESET button with a pointed item like the end point of a paperclip. The TV will turn Off and the TIMER light will flash quickly for about one minute. When the TIMER light stops flashing, you may again turn on the TV. The changes you made the last time the TV was on before you used the SYSTEM RESET button may be lost, however, the changes that were previously saved are not lost.
OK.

Good chance it took out the str regulator in the power supply.

Unplug the television, let it sit for an hour an try to plug it back in. That should resolve the problem. if it still flashes green after you do this, use the "reset" button again. Let me know if that works.

You will need to cahnge the capacitors on the DM board, very common problem. The V21 V19 DM repair kit at the following link contains the replacement capacitors and detailed instructions. Its listed under the repair kits catagory at the following link.

sounds like the unit is truly unhappy, eh? the power board is most likely down de tubes, mon

hey i have had the same problem but i unplugged the tv for awhile about a half hour and then plug your tv into a different wall outlet if you can and should work. It worked for me, i had it plugged into a surge protector then i unplugged it from there, let it sit of half hour then plugged into different wall outlet and worked. so try that and see if it works.

on the signal board replace the caps by the 5/9 volt regulators. c2p04 is the main culprit. 6 caps in total can be changed. I believe c2p05 also.
