Emerson tv mod. Ewl20s5

SOURCE: Emerson EWL20S5 20 in.

This TV has a network of diodes connected to a PROTECT-1 line monitored by the control IC. If any circuit pulls this line low, the control IC turns the system OFF. The diodes act to isolate all the circuits from each other, its called a diode-OR circuit.
You can troubleshoot by opening a diode which disconnects a circuit from pulling the line low. I had a hunch the EL backlight board was bad, so after opening that protect line the power stayed ON.

I found a bad .068uF 250V cap on the transformer primary, it measured .002uF. I've replaced the cap and the other two on the other transformers just for good measure.

It probably took more time than the TV is worth, but my friend's Mom will be happy, and thats worth it.
I hope this helps, look around for the service manual, it can be found online.

You will need part number 1EMN20039B just do a goolge search with that part number. Good Luck.

The most common problem for this set that will cause shutdown after a few seconds is the inverter board. Looking at the set from the back, it is the long slim board that is normally located on the far left side of most lcd tv's. There are 3 electrolytic capacitors located on this board, and changing them will fix a lot of these sets for this problem. The location numbers of the caps are c330, c350, and c370. If you have any experience working on electronics, I would start by changing these caps. They are very inexpensive. If you would rather just change the inverter board, try shopjimmy.com. That is a good place to buy boards for flat screen tvs.

The set can recieve analogue transmissions or cable signal only, for digital transmission a converter box would be needed
