wow, been had on this set. rain spots, rust, roach poop, missing interconnect cable from av input to mainboard, cable from mainboard to tcon is some rigged krap. no led no power. Have 110vac into inverter board, 160ish dc output from inverter board to main power supply, inerter board already has some new inverters and they check ok, i think i have a main ps issue and probhably a whole lot more. I have no 5v, no 3.3v, nothing.

I will post some pics tommorow this will give you a good laugh.

Oh well. I traded a 27 incher i had $15 into for: this krap emerson set and a working 20 inch sanyo lcd so i should still come out ok. I guess the good thing is now i have 6 good inverter transformers....

well its toasty i think. Ive got 160 or 170vdc fromn the inverter boasrd to the main power supply board. I have that same 160 into the transformer, and absolutely nothing out of the outpuit side. SO i have a bad power supply transformer, and whatever the eff else that might be wrong with this thing.

I believe this shall be a parts set. THose inverters will come in handy someday

Usually, anything that had roaches is trashed. Its almost the same as water getting inside - you dont know what circuit got fried. That roach poop is conductive and not worth your time cleaning unless it was a 52 inch or something.

hi guys. Just picked up another craigslist gem. Its a 32" emerson lcd.

Looking at this set, it appears to run the same chassis and plastics as a sony bravia. I will document this set with several pictures so you can confirm or deny my suspicion.

WHen powered on the led goes from red to blue, tv comes up with a picture, then tv immeadiately shuts down, back to red standby led. I have been told its been fussy to power on for awhile now and finally got to the point of not staying powered on now at all.

I suspect bad caps. Getting ready to tear it down now. WIsh me luck.

I found the same Emerson model on the curb near my home waiting for bulk pick-up. tossed it in the trunk and a year later found it buried in the shed. Your post/thread helped me focus on the correct board (inverter). The secondary all tested the same Ohms but then when I tried unplugging all the connectors and then plugging back in it would not light up so I put them all back on and the symptom was the same, however, I heard a barely audible bzzzzt sound and saw a very thin wisp of smoke coming from the area of #6. I hit power on a again and saw the smoke come from between the two wires of #6 that were touching half way to the black rubber grommet. Plain as the nose on my face is a chard section on each wire where they were touching. I spread all wires apart on all transformers and powered on and TADAAAA! The char looks deep and I cannot see wire inside the hole in the insulation. Not sure whether to cover liberally with electricans tape or splice first. (are these super fine wires that are difficult to splice?). If it works, don't fix it? Picture upon request, I just joined so need to learn how to post pix.
