The power supply section of the tv needs a voltage rectifier or diode or similar possibly there is a fuse inside but there must have been a reason for it blowing. Usually aging electrolytic capacitors are the cause

SOURCE: remote control code for 32 inch lcd EMERSON TV

I succeeded is using the DirectTV remote control for the Emerson 42" plasma TV, by using a Samsung code. On my TV, was 10060. If this one does not work, there are a bunch of others that might work. Good luck

SOURCE: my emerson tv won't turn on

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.6_2_2012_12_46_56_am.jpg6_2_2012_12_47_12_am.jpg

Emerson Model LC320EM3FA TV will not turn on?


Fault to the main power supply regulator section. Either it will be on a separate board, or on the part of its main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

How do I change the channel on my Emerson LC320EM3FA 32" flat screen TV? I've tried the auto programming that does not work. When I press the channel button on the TV, it just changes the source...


Has it detected any channels? Are you connected to Cable TV wire or antenna? Has it worked before? Without it detecting channels, all it can do is change inputs.

No sound from my Emerson tv


try a dvd to see if sound via the audio/video jacks and also look in set menu to see is speakers are turned OFF or not, the sound if works with a dvd means it is a hookup or similar issue and the audio circuit in the set is good. Also if set has headphone jack see if that works.

Emerson tv....won't turn on...stand by light won't go off


Not making it on or out of standby---first place to look is the power supply for signs of damage or puffed up filter caps there.

My tv won't turn on


If the screen is damaged/shattered you are done. Not worth the cost of the part or labor.

If something else use the "make a comment button" on this page to let me know.
