Mitsubishi LT-52144 will not power on. blinking blue light

I also have a Mitsubishi LT 55164 with blinking green status light...does nothing else...reset does no good, also tried to reload software with no difference. Replaced power and inverter boards button stop the same. No obvious bad components on boards. Help! Anyone ever actually fix one of these?

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.
If blinks continue without any pause, the main board is faulty or firmware is corrupted.

Blinking light means your bulb is blown and needs to be replaced. Very easy to do. Check owners Manuel . Shop the bulb on ebay

Hello. I was in a live session with you earlier and it seems like you accidentally closed the window. Does the tv tv click on momentarily before it shuts off and starts blinking?

if not in warranty, and if you are a DIY i would open and look at power supply board, you may see a cap or 2 bulging open.

you need to buy the power suply go on line
