My UMC 22" LCD TV Receiver, Model No. : UMC-L22A01C01G-796, will not show any picture at all. I have changed the output to see if it will work but it doesn't. Earlier today the AC to DC box stopped working and so I bought a new one. Could you please tell me if i can do anything?

Hi and welcome to the forum.
Let's clear up a few things first...
You say you have no picture, do you have any sound?
Is the standby led lit?
What do you mean by "I have changed the output to see if it will work but it doesn't"?
How do you know the AC adaptor stopped working?, did you measure it's output with a voltmeter?
Did you buy an adaptor with the same output voltage, current rating and DC output plug polarity?
