Blinking Green LED

Hi,
If the led light flashes green continuously, the fault came from the DM power supply. The faulty parts there are the electrolytic capacitors. Let me know if your handy with electronics and I will assist you to fix it yourself.

a red led usually indicates an error or defect. if removing the power for several minutes (or hours like you did) does not reset the error, then i'm afraid that you will have to replace the device completely. however, the root cause may still be found before the router. have you tried unplugging and replugging the modem as well?

check the fuse inside the tv

Thats the great sound of Exploding capacitors on either the power supply board. or another one in there. Now the set is in fault protection. It tried to warn you with the RED blinking LED that there was something amiss by shutting itself down. When you unplugged you reset the error and allowed it to do it again.

Best Regards and Smper Fi

Thats a common problem when the caps on the DM need replacement. They will function fine untill power is interupted then the set will not complete the boot sequence when power is reapplied and the led will just continue to blink. Hers a link to the kit that will usually repair that issue the kit comes with instructions.

how long was it blinking. after a complete loss of power the green light will blink on power up as it is resetting itself. It says in the manual that it should take about a minute. Over the last two days I've have to reset it several time both by unplugging it and using the manual reset button and it has taken about five minutes for the blinking green light to clear.

Unplugged my Sony for 36 hours from wall and it solved the problem

I had exactly this problem. After plugging and unplugging it multiple times over several weeks (even plugging it in quickly after it was unplugged but with the green light still flashing as suggested here) all to no avail, it just started working on its own one day. It worked for a few weeks and then the problem re-appeared.

InFocus tech support recommended:
1. Check whether the lamp door is securely closed.
2. Check the color of the LED and the number of time it blinks. (For me, a very fast almost flickering flash)
3. Does the fan operate? (My fan would go on when plugged in)
4. Remove the lamp module, shake it gently and reseat the lamp module.

For me, these steps did not work. InFocus then recommended that I send it to ProjectorDoctor http://online.projectordoctor.com/, and it was diagnosed with a bad power supply. $395, but it is fully functional again. Good luck.........

have you tried the menu and device buttons held in together to activate the led error code feature? Let me know the error code.

Check C9B01, C9B02, C9B10, and C9B11 (1000 UFD 16) on the DM PCB, if they are bad replace them with part # 181P734030..if they are ok then the DM pcb itself is bad part # 934C067002
