Emerson LC195em9

[knoxrebel]

Emerson lc195em9 2 Lcd tv w/vga input. Power light comes on then immediately starts fast blink on and off. Lcd panel does not show any backlight/video. Examined all caps and tested with esr meter, all within tollerances.

Not sure where to go from here.


The missing capacitor on the inverter board was fine, needed to use it in a pinch and it has been replaced with Rubycon

1) I didn't download to take a look, but service manual for EMERSON LC195EM82 LC195EM87 might be the same as your model?



2) Great clear photos. Thank you.

Re: Emerson LC195em9

Take a look at the area of the left-most connector in the first picture. The jumpers in that area are marked to indicate ths voltages they carry. Verify they are correct.

Absolutely it is legit. Everyone here uses it.

Try using Internet Explorer 7 or 8 or 9 and looking for the Get Manual icon near the bottom of the screen (just to the right of the picture of the TV).

Okay, now i am confused. All of a sudden the thing starts working properly and displays video. Unplugged and moved to other side of workbench, plugged back in; original problem reoccurs. Checked for loose connections, all appear intact.

Typical of a bad solder joint somewhere. I offer my condolences.

Re: Emerson LC195em9

Is there anything else that i can check as i have already carefully examined all boards with aid of a light table to check for holes and cracked joints.

About all you can do is flex the various board slightly with power on to see if one particular board causes it to quit. IF you can localize it to a small area, the resolder everything in that area.

Re: Emerson LC195em9

i currently have the same tv, and same problem.
Questions:
1 Did you ever find a manual for it or are the above manuals "close enough"?
2 Did you ever find a solution?

thanks
