Hello,
I have an Emerson LC320EM82 S here and it doesnt want to work.
When i first plug it in, the red standby light comes on.
I press the power button
The power light flashes green a few times
I notice the entire screen gets slightyl lighter to a grey almost and DIGITAL TELEVISION comes up in white in the bottom right cornner
It then turns of and standby light is on.
Ive googled around and heard the power transformers for the LCD bulbs one or more of them may be bad due to the secondary winding opening and it shuts down for protection.
Ive heard you can check these with a multimeter and i have some electronics backround but not sure how these transformers are hooked up. Here are some pics im hoping someone could draw on them or tell me how to test each one.
i know thier the 6 black rectangles up at the top in this pic
 the brown stuff every where just looks like excess resin to me
bottom side of #1 transformer, not sure where to put my test leads. (or what values are to be expected)
Ive also found out that its not really Emerson who makes it its Funai and thats who id buy the new parts from. (where and how on thier site????)
thanks for your help! |

Had an Emerson/Funai a month or two ago stayed on with set on A/V1 or other input. On tuner grey w/"DIGITAL TELEVISION" pix would fade and set would cycle set on/off. Was bad digital main board.
Transformer secondary should be on transformer side of blue caps - not at bulb connector (hundreds to thousands of ohms), primary opposite (few tenths to few ohms). Or measuring matching pins of each transformer, one to the next, all should have same reading, is another way of looking at it.  |

cool so just test between the pins in the white plugs where the pink and white wires would be when its hooked up
6: 128.3Kohms
5:128.5Kohms
4: 127.9Kohms
3: 127.1Kohms
2: 128.9Kohms
1: infinite

NO.
"on transformer side of the blue caps - not at bulb connector."
A transformer wire is on one lead of blue disc cap and a bulb pink or white is on the other lead of blue disc cap. |

Sneaked in some info when I wasn't lookin'?
Looks like at least 6 pins. ?maybe 8? The two pins the printed "arrows" are pointing at should be the ones. Hard to see foil runs under white paint.  |
