Emerson LC320EM2 Dead

[CraigR]

Hello all! This time I have a Emerson LC320EM2 that is dead with no light or any sign of power. I read through a couple other threads here on this model and it seems my tv is a little different. The fuse is good and I visually checked over the caps or anything that might have gotten hot. I also tested the diodes on the hot side and came out good. I did see that they make a power board repair kit for $25 and was wondering if I should just get that but according to another thread on this TV it did not help out the other guy. Does anybody have an opinion on this??

Well I just removed the board to have a look at the underside and it looks like someone was in there I'm guessing to put that kit in and had way too hot an iron and just destroyed the traces on the board so looks like I need another board now.

I hate to revive an old thread but since this post I have done about 8 of these TV's and just get a kit and it has always fixed the tv until now. After installing the kit still no power but now high pitch squeal. Just wondering if anybody has a quick answer without going into major diagnostics?

Re: Emerson LC320EM2 Dead

Question is what components did you replace?
Did you force the PSU on without the main board?

Here is what I did to mine: https://www.badcaps.net/forum/showth...hlight=emerson

Re: Emerson LC320EM2 Dead

you switched diode D605 twice? or is that a typo?

LOL yep typo

Re: Emerson LC320EM2 Dead

Did you measure all voltage rails when this thing is chirping? I am thinking something is shorted and loading the PSU down.

Re: Emerson LC320EM2 Dead

No, unplugged it right away because i did not want to fry anything. I was hoping somebody might have ran into this before and might see what I missed replacing.

Re: Emerson LC320EM2 Dead

Does it chirp in STBY or did you turn the TV on?

Re: Emerson LC320EM2 Dead

Just plug it in and a very quiet steady squeal. No light on front and TV will not turn on either.

Re: Emerson LC320EM2 Dead

did you disconnect the main board and plug the PSU in?

Yes, same results.
