Attached is a crappy pic of a bad diode on tv board which the HDMI port stopped working. The other diodes test fine for the other HDMI port. What type of diode is this? I cant see any numbers on it or anything.
I have not tested it off the board but I am 99% sure its bad. I tested the other HDMI diodes and that one diode tests bad. I know its out of focus and will try to get a better pic. I will have to use a magnifying glass to see anything on it.
If as you say you are sure its bad then you may as well take it off the board - it will have to come off whatever.
If it is paralleled on another section of the board it may be easier to read the part number
on its twin.
Is the other hdmi port working ok?
I can see that it is connected in series with the diode on the left, so it can be the TVS protection diode. If we can get the make and model, then we can locate the service manual for the TV. Did the TV get hit by the surge?
I will get the make / model when I get home. The other HDMI port is working which makes me think that one diode is bad. It looks like 2 diodes per port so I test them all and the one diode that is bad, the port doesnt work. A service manual would be great! Ill post the info asap.
