I have a TV that is labeled Emerson on the front but Funai on the model label. It says it is alc320emxf. The issue it is having is that it has now lights or power when turning on. I checked the switch and I get contact when pressed. I checked out what I think is the main power board and on the 2 wire plug it has around 160 volts constant. That plug connects to what I think is the inverter board. I also checked the main diodes and fuse, they checked fine with a ohmmeter from what I can tell. I did find two sb390 Schottky barrier diodes at d641 and d642 that ohm out to .1 ohm. I don't remember the difference between testing Schottky and standard diodes if any. They are still in the circuit as of now.
With that said I am leaning towards these Schottkys but its been so long since I had dealings with them. I don't have any of these diodes here or at home or I would try them. I can get them but I have to go through and get purchase orders and that is a pain on small items like this. Would it be a chance of a different board being bad? Also due to age would it be better to just buy a replacement?
Thanks in advance for help.
