Emerson LC320EM9 32 in. LCD HDTV - Page 8 - Answered Questions & Fixed issues

I had a tv come in doing the same thing and a cap had been ripped from the circuit board I traced it back to the remote input from the front of the chassis. i havve no dea what value to but back so i have replaced it with several various fareds none work perfectly but some are better than others.

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:
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.

U check the power sourced like the other equipments that plug into that a/c power outlet work?Yes,than tries tv unplug,replug it back like about an hour later by letting the tv to do a resetting itself back to the factory setting.The tv now it should be working again.If the tv still have the same result?Yes,than the tv have a power supply board it is dead.That the board where the power a/c cord plug into it.U have some basic mechanical skills like take things aparts and putting it back togther again?Yes,tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish power suppy board for the replacement.

Hello
Your TVs system memory IC has damaged. System memory IC is one which stores all the data we give to the TV externally. This IC is a small one which have 8 solder terminals, and very cheap to buy. Can be located very near to the main system control IC. All the data we gives, and the data that has processed by the main system IC, that is brightness, contrast, colour etc:- are stored in different memory locations of this IC, and wiil be retrived back to the system control IC, as and when requred and preocessed by the system control and given to chroma and other section of the IC as we switch on the TV every time. Although this is a Small one and cheap to buy, its function in the circuit is typical. In fact this IC controls the all other functions of the TV.
Replacing it will solve the problem of your tV. It is very important to note the number of this IC. The number will be printed on it, and should be noted when buying a new one. Insist on same number, and not replace it with equivalents. The set won't even switch ON if you replace it with other numbers. It can be bough from most of the electronic soare part shops at your town. OK.

Hello,

Let verify first to narrow down to where the problem can be. First, check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. To get the sound repair, it can be from $150 and up, so if you can put up with using the good set of Powered PC speakers which actually give better sound than the tiny speakers inside the TV, I would keep using it that way, you may want to find out if the on screen sound setup will allow you to set the audio line out to be VARIABLE which means the sound output feeding the PC speakers can be varied using the TV remote control, then all you have to do is to set the PC volume to about half way up and set the TV volume to what ever you want.

Hoping this will work to solve the problem..

You have a defective LCD panel. If it is under warranty, exchange it ASAP. If not, it's time for a new TV, as it is usually more expensive to repair it than buy a new one.

Hello
Sky remote code for Wharfedale TV are:

065

584

699

OK.

Yes,those white hard residue are glues.The fuse just don't blow like that.The power supply board could have more trouble than that.If u replaced the tv fuse and tv still don't work.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power suppy board for the replacement.

There could be a setting on this model in the menu to set the type of scene you are watching...like movies, sports, etc. Sometimes these settings will affect the sound. Also check all that is included in your sound menu. Test each setting in the sound menu.

This tv not worth trying to fixed,drop on the floor 99.9% :( the tv LCD screen panel it is dead also.The replacement of the tv LCD screen panel will cost the same as a new tv,if u can buy it refurbish at all,LCD screen panel are very important to the tv and very limited in productions.Sorry this tv now only can be used a salvages tv only for it electronic pcb boards only,if those boards not already have cracks in them.

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.

All these can be checked on the power supply board.

But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Regards.

use the warranty

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering, and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.

Hello
If you have unpluged the TV from wall socket and it doesn't come On when you plug in back, either its power supply system or its stored memory has the trouble. Look whether the power indicator light coms on. Ensure that the main power ON/OFF switch at the front panel of the TV is ON. If the front panel power switch, control switch of your wall socket, and all the other electrical connections are OK, and still the TV doesn't come ON, surely the power inverter baord has the trouble and must be either repaired or replaced. if the power indicator light comes on, and your TV doesn't come ON by remote POWER ON button, the settigs that were stored has vanished, and resetting it to its original setting is necessary. Follow its manual for 'initial setup" and so all the recomended setting there. OK.

Check out ebay.

Hi, It sounds like a problem with the power supply module. When the power supply notices a problem with the TV it wont allow it to start as a safety measure. It could be just a simple resistor fault or something bigger. Get two or more quotes and dont let them tell you its the screen without any tests. Good luck. PS keep it switched off, if there is a fault you dont want a fire. Good luck.

You would use vesa screws 4mm x 10mm - for non-recessed vesa mounting holes.
4mm x 20mm + approx 1cm spacer - for recessed vesa mounting holes

Tv now turn on have no LED power light indication at all or blinking?Tries tv unplug,replug it back like about an hour later for the tv to do resetting itself back to the factory setting.The tv now should be working again.Not,if have same result,the tv power supply board it is the causes and the problems.That the board,where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbih power supply board for the replacement.

Try website like Remotes.com to buy an original remote.

Unless the tv has a VGA input, or the laptop has a HDMI output, I am afraid you are going through too many conversions to make this work.
