I tried replacing the power supply in the set, I ordered a new one and it didn't have any positive effect. Not sure what to do next, but I will keep troubleshooting the set. I assume there is a short somewhere in the set.

I'm back, and it turns out that the issues was with the Main Board of the tv. Bought a new one, plugged it in and the tv works like new again!

Hi This is most likely a problem in the High Voltage section of the set, probably the High Voltage Transformer, this is something only a qualified technician should service due to the dangerous voltages and shock hazzards involved.

19 or 20" Emerson TV (looks like EWF2004) about 6

The power source is forced to deliver more power than what it's rated for because the capacitors have aged and have started to lose their insulating properties so much that when heated by the normal functioning a lot of current is wasted thru them - they start to act like a short.
You must replace all of them ASAP or they will fail and the entire tv will be fried.

After tv is on for approx 20-30 mins it starts to make a loud high pitched squeal or whine. once turned off for approx 10-15 mins can turn it back on for another 20-30 mins before squeal will return....

Sounds like a problem I had with a Polaroid t.v. Take the cover off the back and look for capactors that are buldging on the top. The top should be slightly concave. If they are convex at all, you can buy new one at Radio Shack and replace them for under $5.00

I need to find a manuil on this manuil for emerson tv ewf2004 23 inch

Dear arlenejune1,

Below is the link to the official manual for Emerson EWF2004 20".

http://www.emersonaudiovideo.com/pdf/om/EWF2004.pdf

It actually seems that Emerson EWF2004 23" does not exist. If you do have this model, try working with this manual and if that does not work, I cannot do much else for you.

I hope that helps,

Tv. will not turn on

You might have blown an in line fuse. It would be right where the power cord hooks up to the TV. If that's the case and you replace it and it blows again call the repairman. Real good chance it just blew though. Good luck.
