Question about Emerson Televison & Video
It is funny to see this post since i just worked on this same unit a few days weeks ago, i replaced the power supply and the inverter to no avail, it acts so much like a bad inverter but the actual cause was much more fun, the set is detecting a no_light condition by mistake, this could be caused by a bad inverter but in your case (and mine) it was not, the board looks for a 5v supply to show up on the connector to the mainboard/inverter baord if it is present it orders the power supply to continue its power on cycle if not the set attempts once more to power on the inverter if it still does not detect the Inverter_on pulse to the main board it orders an emergency shut down(flashes faster then off)
The problem stumped me and i had 2 hours of troubleshooting using a meter and a scope and found the main board was the issue, yes the digital board, weird i know but i changed the part and fixed the problem. It turns out i am not the only one to have this kind of fun a buddy of mine did the same thing a few months back found a bad digital board same as me, and another guy I worked with had the same issue but on his it was the connector from the digital board to the main board had lifted slightly he pressed it flat and wham bam Fixed but in all cases it was the Digital that was holding the set from powering on, you may want to be sure all the connectors are fully seated but if that doesn't fix it replace the board.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
