Does not turn on

There might be a cold solder in its PCB... If the problem is not serious. If you know how to do it, if not a service technician can.

this is very common. it is the power supply going bad. it should run at 130 volts dc. but it is now running much lower that this. just enought for the tv to come on. but not enough to power all the circuits right.

if it was a new tv you can ask the supplier for check up it was covered with warranty.

Will ur tv the power supply board finally completely gave out.That the board where the tv power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish power supply board for the replacement.

No,bulb on this tv.Ur tv the power supply board finally gave out,5 years that a very good tv u got there,most tvs last only 3 or 3 1/3 years max.Than the power supply board or the other boards gave out.

sounds like u have a bad mainboard.

Dont know if this will work for you or not, but my brother gave me his because of the same problem. It would power up and a green light would come on, then after 10 -15 seconds it would change to a red blinking light. I plugged a usb cable into the service port on the side and left the other end unplugged. Then plugged the tv back into the power. i took a small screwdriver and ran across the contacts in the end of the usb cable until both the red light and the green lights came on. I did this several times listening fot the clicking noises in the TV. after doing this for approx 20 seconds, i pressed the power button and the TV worked fine. 5 days now and no problems. Only thing I can think is I somehow reset the software and now it is working fine. Hope some of you can figure this out and give it a try. if the TV is just sitting, you have nothing to lose

My Mitsubishi WS-73713 had the same blinking green timer light problem and would not turn on. I tried the reset button and unplugging power to no avail. I found that by simultaneously holding down the remote control "power" button and "volume" button for about 30 seconds the blinking light would go out and a solid green light would come on. Even though the solid green light came on the unit would still not power up. After doing this several times however the unit did finally power up in a normal mode and appears to be working again. It's worth trying before calling in for an expensive repair. PS - From here on out I'm sticking with SONY or Toshiba sets which have given be great service.
