SOURCE: my flat screen tv does not have a picture or

I've had the same problem with a 32" model LC320EM82S. All the Emerson TV ( no matter what size ) are having the same issue.
I'm sure with your TV, the green light is blinking before the TV automatically turns OFF. Basically, the TV is trying to power up the screen and has failed. Protection mode turns the TV OFF to prevent other parts from being damaged inside.
My solution for fixing my TV was replacing one bad inverter transformer of six on the Backlight Inverter/Power Board. Here is what my board looks like: 767c946.jpg
You can see the six inverter transformer on the bottom of the board. It's what supplies power to the screen. Your board may look similar. You can sometimes find a whole replacement board over the internet for a good price. Shopjimmy.com is a good place to start. Just start searching by your TV model number.
If you have some electronic experience, you can repair the board itself by finding a Service Manual over the internet for less than $20. It will have all the part numbers, schematics, and diagrams you need. I would investigate the inverter transformer for your problem.
I hope I helped you out with your problem.

Hi kellswty15,

Here are some basic steps that will help you fixing the problem.

I'm assuming that your unit is dead set without an standby LED light and your outlet is live.1.Power cord - check the cord it might be opened (no continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse- sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I would advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts in the power supply, you may visit the linkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.

4.If you see that the fuse is intact , don't attempt to touch anything because there some fatalcomponents stored electricity enough to hurt you with a simple mistake only. I would advice you to look for a professional to troubleshoot the power supply. If you want to repair it yourself make sure that you have necessary tools and test instrument. First check bad solder joints(re-solder all cold solder), leaky electrolytic capacitor(sometimes it has bulged at the top but not all, you better have a capacitor checker), open/shorted regulator transistor/IC(mounted in heat sink), open fusible resistor (caused by shorted regulator Transistor/IC), shorted zener diode.

You may also replace the power supply board for your convenient, click this LINK. Double check the actual part no. of your board before ordering.

Also check if your unit is under warranty/extended warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.

Hope I helped you.

Have a nice day!

Thanks for using fixya.

Sounds like capacitor/s failing on the power board. This is a common issue and there is lots of literature and even videos on how to perform the repair on web. A shop will charge upwards of $200 for this repair yet if you find the components and only have them change those; perhaps they will work with you on cost. GL!

Need codes to program a dishnet remote to a emerson tv


Turn on device you want to control (TV, VCR, DVD)

Press and hold the CODE SEARCH button until the red indicator light remains red, then release

Press the desired mode button (TV, VCR, DVD) and release

Press the POWER button slowly, but repeatedly
until device turns off. While doing this, the red indicator blinks then stays lit

Once the device turns off, press and release the Enter button to install code. The remote should be synced to the device.


Another view:
Someone on another board pointed out that with some newer models you do not need to press the CHANNEL UP button repeatedly. Rather, you press it only ONCE, and the device will cycle through all the code possibilities. When the TV turns off, it means that the proper code has been found. Immediately press the Enter button to install that proper code. This method (and no other) worked for me.
