Hi!
I have a Vizio E65X-C2 with no 5V_Stdby. I've uploaded a couple pics, but couldn't get the lighting right.
I found a bad diode, DM855, and the diode reads:
I believe the part number for that diode is SB5150. Could someone help me find a compatible diode for this PSU?
There are three diodes in that section and they're connected to the output of a transformer. I'd like to understand this transformer a little better. It looks horrible, like a child wound it.
I suspect this IC might be dead, ICB801, but I am having trouble locating a datasheet. Aliexpress is selling a lot of 5 and have it listed as a voltage regulator.
Does anyone know what this IC is? Does any one know the purpose of the transformer? I'd love to learn how to test it. I've seen videos on how to test various transformers, but when I check continuity on the input side, I see ~0 ohm resistance between certain pins and same for the output side.
Thanks!
