When ordering Emerson replacement boards, you have to include the first 3 digits of your serial number as in DS1, DS2,ETC---
Did you do that-

My first solo shot from the parts cannon was ineffective.

Wont power on, transformer squeals on old power board and new power board if the main board ribbon cable is plugged in.

After reading many of your posts I trust you can provide me with a solution if I provide you the correct information. Does the 50" 39" size difference matter should I go ahead and purchase the board you recommended?

Model LF391EM4
S/N DS3

Will a new main board make my TV work again or will I need an IR board as well?

If you disconnect the power supply to Main Board, and TV Power Board squeals, then replace Power Board.
If you disconnect Power Supply to Main Board, and squealing stops, replace Main Board.
This theory is not 100%

So go ahead and buy the main board you recommended for the 50" TV with mine being a 39" TV?

Can you help me! My tv was dropped. It will turn on but the keyboard controller will not work. Took the back off and noticed one end of the cord has been disconnected but I have no idea where to connect it back to.

I just tried this on my emerson tv of over 5 years. After reattaching the LVDS cables for the main and power board, I finally tried replugging the ir sensor with my tv on and it started working again! It barely started having issues with it today and I've been at it all day trying to fix it until I found your guide online. I ordered a new ir sensor for replacement soon 😊
Thanks for all your advice it really helped!

I have a Emerson 45 that the power light is on and it won't turn on. The capasitors are fine nothing wrong there. I took the power button completely off for now and am using the remote cause the buttons there are broken and don't work anyways. Anything you can suggest looking for?

Unknown error code. I believe it's a capacitor on the CPU panel. Specifically capacitor 6?

Tim here, would you have any more of the Ba31M0G0203 (for LF320EM4A) i/r boards left? Hope this fixes the problem. TV will not turn on, just blinks 4-5 times and goes to standby I guess. I appreciate your help. Thanks.
